Psilochorus sphaeroides (misidentification; see

Notes below): Jackson and Rowe, 1987; Jack­

son 1992; Jackson et al., 1992.

?‘‘ Psilochorus ’’ sp. 1: Huber, 1998: fig. 2M (see

Notes below).

NOTES: Robert Jackson and coworkers did not publish detailed collection data of the material they identified as Psilochorus sphaeroides (only ‘‘Cairns’’, or ‘‘near Cairns’’). A label accompanying the type material of the present species reads ‘‘R. R. Jackson, voucher specimens’’, but these specimens were collected after the publication of all the papers listed above. Nevertheless, since the only four vials in the QMB containing specimens collected by R. Jackson contain the present species, I find it highly probable that this is actually the species studied by Jackson and coworkers.

Secondly, the species whose ‘‘valve’’ was studied in Huber (1998) is either conspecific or very close to the present species. (I copied the erroneous label, saying ‘‘Mittag Mittag’’, which should be ‘‘Millaa Millaa’’.)

TYPE: Male holotype from Crystal Cascades near Cairns (16°58̍S, 145°42̍E), Queensland, Australia ; Dec. 1992 (R. R. Jackson), in QMB ( S34679 View Materials ) .

ETYMOLOGY: Named for the Tjapukai, a rainforest tribe in northeastern Queensland. The species name is a noun in apposition.

DIAGNOSIS: Distinguished from most congeners by the modified male clypeus (figs. 2–4), from all known congeners (including the very similar Wugigarra mamu ) by the shapes of procursus tip (figs. 10, 11) and dorsodistal bulbal elements (fig. 12).

MALE (holotype): Total length 3.9, carapace width 1.84. Leg 1: 53.9 (13.1 + 0.7 + 12.4 + 19.7 + 3.1), tibia 2: 8.1, tibia 3: 6.0, tibia 4: 8.4; tibia 1 l/d: 79. Habitus and prosoma shape as in figs. 1–4. Carapace ochre with wide median and marginal brown bands, thoracic furrow black (fig. 3).

Clypeus ochre yellow, distally modified into black sclerotized rim (figs. 2–4); sternum dark brown, with small yellowish speckles, margins lighter (fig. 4). Chelicerae light brown, with pair of black pointed apophyses medially and low humps at their bases (fig. 5); apophyses not visible in lateral view (fig. 1). Palps as in figs. 6–7, mostly ochre­yellow, only procursus and bulb partly brown to black; procursus tip and bulb distinctive, as in figs. 6, 7, 10–12. Legs ochre to light brown, without dark rings, tips of femora and tibiae whitish; curved hairs on tibiae and metatarsi; without spines and vertical hairs; retrolateral trichobothrium of tibia 1 at 8%; tarsus 1 with>40 distinct pseudosegments. Opisthosoma roundish, as in fig. 1, gray, with black and white spots except ventrally; genital plate brown, about trapezoidal; brown plate in front of spinnerets.

VARIATION: Tibia 1 in 7 males: 10.1–12.4 (x = 11.4).

TYPE: Male holotype from Bellenden Ker Range, Cableway Base Stn (17°16̍S,

145°54̍E), 100 m elev., Queensland, Australia ; Oct. 17–24, 1981 (Earthwatch/ QMB), in QMB ( S27760 View Materials ) .

ETYMOLOGY: Named for the Mamu, aboriginal rainforest dwellers in northeastern Queensland. The species name is a noun in apposition.

DIAGNOSIS: Distinguished from most congeners by the modified male clypeus (cf. figs. 2–4), from all known congeners (including the very similar Wugigarra tjapukai ) by the shapes of procursus tip (figs. 13, 14) and dorsodistal bulbal elements (figs. 15, 16).

MALE (holotype): Total length 2.9, carapace width 1.42. Leg 1: 38.9 (10.0 + 0.5 + 9.6 + 16.1 + 2.7), tibia 2: 6.1, tibia 3: 4.4, tibia 4: 6.4; tibia 1 l/d: 85.

Legs as in W. tjapukai , including curved hairs on tibiae and metatarsi; retrolateral trichobothrium of tibia 1 at 7%; tarsus 1 with>40 distinct pseudosegments. Opisthosoma identical to that in W. tjapukai (cf. fig. 1).

VARIATION: Tibia 1 in 7 males: 9.6–10.9 (x = 10.4).

FEMALE: In general very similar to male; tibia 1 in 8 females: 8.1–9.5 (x = 8.6). Epigynum externally not distinguishable from that of W. tjapukai (cf. fig. 8).

DISTRIBUTION: Known only from the Bellenden Ker Range area near Cairns, northeastern Queensland (map 5).

Wugigarra kaurna , new species

Figures 17–32 TYPE View Figs View Figs View Figs : Male holotype from Bunyeroo Gorge (31°25̍S, 138°34̍E), ABC Range, Flinders Range National Park, South Australia, Australia; May 16, 1991 (D. Hirst), in SAM (N1999/717).

ETYMOLOGY: Named for the Kaurna, an aboriginal tribe from the Mount Lofty Range area. The last woman survivor, Ivaritji, died in 1931. The species name is a noun in apposition.

DIAGNOSIS: Large species, distinguished from congeners by the tip of the procursus (figs. 22, 23), the distal bulbal elements (figs. 24, 25), the shape of the epigynum (fig. 26), and the three pairs of lateral spots on the car­ apace (fig. 18). The AMS has a possibly closely related species from Capertee Valley (~33°10̍S, 150°25̍E), differing with respect to the procursus tip (AMS KS44134).

MALE (holotype): Total length 4.8, carapace width 2.03. Leg 1: 47.0 (12.8 + 0.8 + 12.5 + 18.1 + 2.8), tibia 2: 8.9, tibia 3: 6.7, tibia 4: 8.9; tibia 1 l/d: 63. Habitus and prosoma shape as in figs. 17–19. Carapace pale ochre with brown marks as in fig. 18. Ocular area pale ochre, slightly darker laterally; distance PME­PME 0.215; diameter PME 0.145; distance PME­ALE 0.065; diameter AME 0.095. Clypeus with pair of dark stripes (fig. 19); sternum brown, with small yellowish speckles. Chelicerae light ochrebrown, with pair of black pointed apophyses medially and low humps at their bases (fig. 21); apophyses visible in lateral view (fig. 17). Stridulatory files as in fig. 31. Palps as in fig. 20, mostly ochre­yellow, only procursus and bulb partly brown to black; procursus tip and bulb distinctive, as in figs. 22– 25. Palpal tarsal organ as in fig. 30. Legs ochre to light brown, dark rings on femora subdistally, patellae + tibiae proximally, and tibiae subdistally; with many curved hairs on tibiae and metatarsi 1–3; without spines and vertical hairs; retrolateral trichobothrium of tibia 1 at 8%. Tarsus 1 distally with ~15 fair­ ly distinct pseudosegments; proximally pseudosegmentation difficult to see. Opisthosoma as in fig. 17, gray, with many black and some white spots except ventrally. Genital plate only slightly darker, about trapezoidal; gonopore without epiandrous spigots (fig. 32). Plate in front of spinnerets indistinct. Two spigots on ALS (fig. 29, showing also the usual two spigots on PMS).

VARIATION: There is an impressive north– south clinal variation, especially in size—tibia 1 in 15 males from north of latitude 32°S: 10.5–13.7 (x = 11.3), in 9 males from south of 34°S: 7.3–8.9 (x = 8.3); the males from between 32° and 34°S have intermediate values: 8.9, 10.3, 10.3, 11.2. The same pattern occurs in females (see below). In addition, the number and size of teeth prolaterally on the male genital bulb follows a similar pattern: most specimens from northern populations have several teeth (as shown in figs. 24, 25); towards the south, these teeth get fewer and smaller, until they are completely absent.

FEMALE: In general very similar to male— tibia 1 in 8 females from north of latitude 32°S: 7.5–10.4 (x = 9.1), in 8 females from south of 34°S: 5.5–8.0 (x = 6.7). Epigynum as in fig. 26, anterior plate laterally brown, medially whitish with pocket on short transparent scape; dorsal view as in fig. 27. Spigots on ALS as in male (fig. 28).

DISTRIBUTION: Known from several localities in southeastern South Australia (map 4).

283–285, pl. 23, figs. 6, 6a–d. Psilochorus sphaeroides: Simon, 1893: 481–482 .

TYPE: Koch (1867, 1872) described both sexes from Rockhampton (23°22̍S, 150°32̍E), Queensland. This material seems to be lost, but the ZMH has a male from Gayndah (~ 270 km SE of Rockhampton) from the Museum Godeffroy collection that is very likely conspecific with Koch’s original material (see diagnosis below).

DIAGNOSIS: Closely related to W. yawai and W. eberhardi , distinguished from both by the long transparent scape on the epigynum (figs. 41, 46) (Koch’s [1872] ‘‘ weicher... Fortsatz ’’), from the first also by the cheliceral apophyses not visible in lateral view (fig. 34) and the more slender procursus (fig. 35), from the second also by the lateral cones on the epigynum (figs. 40, 41) (Koch’s ‘‘ kegelförmige... Höckerchen ’’), and the ‘‘stridulatory’’ cone frontodorsally on the female opisthosoma (Koch’s ‘‘ kleines Höckerchen ’’).

MALE (Homevale): Total length 3.8, carapace width 1.55. Leg 1: 36.1 (9.6 + 0.7 + 9.6 + 14.3 + 1.9), tibia 2: 6.3, tibia 3: 4.5, tibia 4: 6.4; tibia 1 l/d: 64.

Brush of hairlike structures on tip of procursus (fig. 47). Legs ochre to light brown, with dark rings on femora subdistally, patellae + tibiae proximally, tibiae subdistally; tips of femora and tibiae whitish; without spines and vertical hairs; with curved hairs on tibiae and metatarsi 1–3 (few distally on femora and proximally on metatarsi); retrolateral trichobothrium of tibia 1 at 10%; tarsus 1 distally with ~16 distinct pseudosegments (fig. 44 shows two from near the tip), proximally pseudosegmentation very indistinct. Opisthosoma shape as in W. tjapukai (cf. fig. 1), ochre gray with blackish spots dorsally. Gen­ ital plate brown; gonopore without epiandrous spigots (fig. 43). Brown plate in front of spinnerets; two spigots on ALS (fig. 48).

VARIATION: Tibia 1 in 5 males: 8.1–10.0 (x = 9.1). Measurements of Koch’s ‘‘type’’ from Gayndah: total length 3.4, carapace width 1.6; leg 1: 10.0 + 0.7 + 9.7, metatarsus and tarsus missing, tibia 2: 6.4, tibia 3: 4.7, tibia 4: 6.7.

FEMALE: In general very similar to male, but palps and chelicerae brown, and opisthosoma frontodorsally with unpaired sclerotized area, opposing part of thoracic furrow that is less deep and more heavily sclerotized than in male. Stridulatory files on chelicerae as in fig. 45. Palpal tarsal organ and palpal tarsus tip as in figs. 49 and 50. Epigynum as in figs. 40 and 41, with anterior plate divided into lateral brown parts with cones and median whitish part with long transparent scape provided with pocket (figs. 41, 46); dorsal view as in fig. 42.

Chelicerae brown with low proximal humps and black apophyses that are not visible in lateral view (figs. 51, 52); with stridulatory ridges. Palps very similar to W. sphaeroides (cf. fig. 35), bulb and procursus as in figs. 53–56. Legs light brown, without any rings; without spines and vertical hairs; with curved hairs on all tibiae and metatarsi, and distally on femora; retrolateral trichobothrium of tibia 1 at 7%; tarsus 1 distally with ~14 distinct pseudosegments, proximally pseudosegmentation very indistinct. Opisthosoma shape as in W. tjapukai (cf. fig. 1), ochre with dark spots dorsally; genital plate light brown, trapezoidal; brown plate in front of spinnerets.

VARIATION: Tibia 1 in other males: 6.8, 7.1, 8.7, 8.8. The male from Gecko Cave, Gloucester, differs minimally with respect to the bulb (arrow in fig. 53: this process is smaller; arrow in fig. 56: more prominent hump).

FEMALE: In general very similar to male. Epigynum without lateral elevations, with median pocket (fig. 57); dorsal view as in fig. 58.

ETYMOLOGY: Named for the Taribelang (also called Yawai), an aboriginal tribe in the Bundaberg area. The species name is a noun in apposition.

DIAGNOSIS: Closely related to W. eberhardi and sphaeroides , distinguished from both by the male cheliceral apophyses visible in lat­ eral view (fig. 60) and the broad procursus (fig. 61), from the first also by the presence of a spine on the genital bulb (fig. 64); from the second also by the absence of a long transparent scape on the epigynum (fig. 66).

MALE (holotype): Total length 2.4, carapace width 1.23. Leg 1: 28.2 (7.5 + 0.5 + 7.5 + 10.8 + 1.9), tibia 2: 4.8, tibia 3: 3.3, tibia 4: 5.1; tibia 1 l/d: 75. Habitus and prosoma shape as in W. tjapukai (cf. figs. 1–4). Carapace with dark pattern as in W. tjapukai (cf. fig. 3). Ocular area ochre; distance PME­ PME 0.105; diameter PME 0.105; distance PME­ALE 0.055; diameter AME 0.095. Clypeus with pair of dark stripes converging distally, not modified; sternum dark brown except laterally. Chelicerae light brown with pair of high proximal humps and distinctively projecting black apophyses that are visible in lateral view (figs. 59, 60), with stridulatory ridges. Palps as in fig. 61, bulb and procursus as in figs. 62–65. Legs light brown, with slightly darker rings preceding whitish tips of femora and tibiae; without spines and vertical hairs; with curved hairs on all tibiae and metatarsi 1–3; retrolateral trichobothrium of tibia 1 at 10%; tarsus 1 with>25 pseudosegments, proximally pseudosegmentation very indistinct. Opisthosoma shape as in W. tjapukai (cf. fig. 1), gray with blackish and white spots except ventrally; genital plate brown; brown plate in front of spinnerets.

VARIATION: Tibia 1 in 5 males: 6.0–7.5; the male from Double Island is significantly larger (tibia 1: 9.7), but is otherwise identical. Several males have on the prolateral side of the bulb, distal to the large spine (arrow in fig. 65), one or two additional tiny spines.

FEMALE: In general very similar to male, but chelicerae and palps dark brown, and opisthosoma frontodorsally with unpaired sclerotized area, opposing part of thoracic furrow that is less deep and more heavily sclerotized than in male. Tibia 1 in 8 females: 5.2–7.2; female from Double Island significantly larg­ er (tibia 1: 9.2).

TRICHOCYCLUS SIMON, 1908

Trichocyclus Simon, 1908: 407 (type species by monotypy T. nigropunctatus Simon, 1908 ; examined).—Deeleman­Reinhold, 1993: 325; 1995: 35–36.

NOTE: The following diagnosis and description do not cover the ‘‘aberrant’’ T. watta , which is assigned tentatively to Trichocyclus .

DIAGNOSIS: Small­ to medium­sized (total length usually 3–5 mm, rarely under 2 mm) pholcids with globular or higher­than­long opisthosoma, mostly with large AME (AME diameter usually 80–130% of PME diameter, in T. harveyi only 70%), apparently restricted to Australia or the Australian region. Distinguished from Wugigarra (which is the only similar genus in Australia) by a characteristic weak zone dorsally on the male cymbium (asterisks in figs. 201, 248, 265); by the absence of the worm­shaped process on the bulb characteristic for Wugigarra ; by the absence of curved hairs on the legs; by the presence of several piriform gland spigots on the ALS (only 2 spigots on each spinneret in Wugigarra ); by the absence of stridulatory files in females; and by the characteristic and conservative shape of the epigynum that has a median projection but lacks a pocket (e.g., figs. 193, 213, 217).

DESCRIPTION: Total length in males usually ~ 2.5–5 mm, only T. harveyi and T. ungumi under 2 mm. Carapace oval, wider than long, with distinct thoracic groove not widened into thoracic pit, often with three pairs of lateral spots loosely connected to median spot by radial marks (e.g., fig. 187). Eight eyes in conservative pattern on moderately elevated ocular area. AME distinctively large (see above), only in T. septentrionalis male on elevation (fig. 244). Distance PME­ALE relatively small (~30–55% of PME diameter). Clypeus never modified. Male chelicerae usually with two pairs of distinctive frontal apophyses, the distal one more prominent (e.g., figs. 190, 199, 211). Significantly different cheliceral armature in T. septentrionalis (figs. 245, 246), arawari (figs. 264, 266), arnga (figs. 269, 270), and bugai (fig. 274). Stridulatory ridges always present on male chelicerae. Male palps large in relation to overall size (e.g., figs. 186, 275); coxa without retrolateral apophysis, trochanter without apophyses; femur conspicuously enlarged (e.g., figs. 191, 238, 256), with retrolateral hump proximally, usually without ventral apophyses ( T. ungumi , T. harveyi , and T. oborindi with brown ventral knob; fig. 277); patella triangular in lateral view (e.g., fig. 192); tibia simple, with 2 trichobothria in very proximal position (e.g., figs. 192, 206, 247, 256); cymbium with characteristic weak zone dorsally (e.g., figs. 201, 248, 265), with heavily sclerotized procursus usually provid­ ed with dorsal apophysis and ventral pocket (‘‘a’’ and ‘‘p’’ in figs. 197, 201, 206, 229, 232, 260, 273; apophysis always distinct, pocket shallow to very deep), distally with brush of hairlike membranous structures (e.g., figs. 216, 221, 229); bulb consisting of proximal globular part and distal sclerotized elements, often with transparent dorsal projection (arrows in figs. 191, 203, 252, 254, 260; asterisk in fig. 220); sperm duct opens close to this projection, without any embolus (shafted arrow in fig. 220). Tarsal organ capsulate (fig. 208). Legs usually long (leg 1 about 8–13 X body length, in T. harveyi only 5.6 X body length), usually medium thin (tibia 1 l/d ~50–85, in T. harveyi only 34), leg 1 always the longest, legs 2 and 4 about same length, leg 3 shortest; with dark rings on femur subdistally, patella + tibia proximally, and tibia subdistally; tips of femora and tibiae whitish; legs without spines and curved hairs, with few vertical hairs; retrolateral trichobothrium of tibia 1 usually at 7– 16%, in T. harveyi at 30%; tarsus 1 sometimes with fairly distinct pseudosegments distally, sometimes pseudosegmentation not visible in light microscope; in SEM regular pseudosegmentation visible (fig. 210). Opisthosoma either globular or higher than long (very ‘‘high’’ opisthosomata usually point in dorsoposterior direction and could be regard­ ed as secondarily long; e.g., fig. 204); gray with black spots and sometimes white spots dorsally; genital plate usually light brown, about rectangular. Male gonopore without epiandrous spigots (figs. 207, 219). ALS with several piriform gland spigots (figs. 195, 209, 224, 225; examined: T. aranda , arawari , arabana , nigropunctatus ); other spinnerets typical for family.

Sexual dimorphism slight, females with shorter legs, often with larger (higher) opisthosoma; female chelicerae without stridulatory ridges. In most species female opisthosoma provided with two indistinct, usually whitish humps dorsofrontally; corresponding side on carapace either unmodified or distinctively elevated (fig. 261). Epigynum shape very conservative, consisting of two plates, frontal plate with median elevation (e.g., figs. 193, 213, 217), rarely with paired indentations (e.g., figs. 240, 241); internally simple, with pair of relatively small pore plates (e.g., figs. 194, 214, 234).

MONOPHYLY: All species included (except T. watta ) share the weak zone dorsally on the male cymbium. This character is otherwise only present in Aucana kaala , a ninetine from New Caledonia. The transparent projection dorsally on the bulb might be a further synapomorphy of the genus, but seems to be absent in some species (difficult to see).

GENERIC RELATIONSHIPS: Trichocylus is apparently part of holocnemines, whether this group is mono­ or paraphyletic. Within this group, the presence of fairly distinct pseudosegments suggests it is basal, while the procursus with its dorsal apophysis and ventral pouch, as well as the reduction of epiandrous spigots, suggest it might form a clade with Physocyclus and Artema (and possibly with Wugigarra ). Holocneminus might be close, but is insufficiently well known. See Relationships above (p. 6) for more detailed discussion.

SPECIFIC RELATIONSHIPS: Several species groups can be identified by morphological characters and are roughly supported by their geographical distribution: (1) The nullarbor group is most diverse in South Australia and southern Western Australia (map 9). T. nullarbor and kokata have identical chelicerae; T. nullarbor and hirsti have very similar procursi. T. pandima is assigned to this group because of the long dorsal apophysis on the procursus, similar only to kokata . (2) The nigropunctatus group, with three species in western Western Australia ( T. nigropunctatus , balladong , warianga ) and with T. arabana widely distributed in central Australia (map 10), share the shape of the procursus and the wide but short distal apophyses on the male chelicerae. (3) The aranda group, just to the north of the previous group (map 11), is distinguished by the rather slender procursus ( T. aranda , djauan , gnalooma ). T. kurara is assigned to this group because the male chelicerae are similar to those of T. gnalooma ). (4) T. septentrionalis is geographically close to the previous two groups, but is highly autapomorphic in structure. (5) The eastern group ( T. grayi , oborindi , pustulatus ), which is presently the only group known from Queensland (map 12), is distinguished by the straight distal element of the procursus. (6) The arawari group, with four species, is only known from Kimberley (map 13), and includes T. arawari , worora , arnga , and bugai . These species share a distinctive sclerotized element on the bulb set with scales (figs. 259, 272), as well as relatively huge pockets ventrally on the procursus; T. arawari and worora have very similar procursi, as do T. arnga and bugai . (7) T. harveyi and ungumi , both from Kimberley (map 14), have an unknown relation to each other and to any other species. (8) Finally, T. watta is assigned tentatively to Trichocyclus .

NATURAL HISTORY: The genus is most remarkable for its unparalleled ability among pholcid spiders to thrive in the Australian deserts, in the ‘‘dry heart’’ of the continent. Summarizing the information on collection labels, the spiders build their webs between and under rocks, at rocky cliff faces and overhangs, at the bases of trees and under logs, and in caves, hollows and wells, and in termite mounds and nests. No single­species study, or any closer published observation, is known to me.

DISTRIBUTION: Presently known from Australia only. The CLD collection has a male of an undescribed species from Togian Islands, Sulawesi, with remarkably similar chelicerae but very different procursus. Within Australia, all described species are from the western part of the continent (west of 140°E), with the remarkable exception of T. pustulatus . However, the collections studied contain (apart from T. pustulatus ) some unidentified females from Queensland and New South Wales (map 2), suggesting that the genus is rare rather than absent in the Great Artesian Basin and in the east.

COMPOSITION: The genus now includes a total of 23 species. Several types of evidence suggest that the actual number is significantly higher. First, nine species are known from just a single locality. Rather than indicating limited distribution, this probably reflects the spotty effort made so far by collectors. Second, the number of new species per decade represented in the collections studied does not seem to be leveling off; that is, six species were represented until 1980, 14 species until 1990, and 23 species until 2000. Third, vast areas of Australia lack any record, probably in part because of collector bias.
