( Figs 4, 11 View FIGURES 1–11 , 26–27 View FIGURES 24–42 , 43 View FIGURES 43–49 , 52, 56 View FIGURES 50–58 )

Pallodes loriai Grouvelle 1906: 327 . Type locality: “N lle Guinée Britannique: Bujakori, coll. Loria” (MCNG); Kirejtshuk 2008: 118.

Pallodes opacus Grouvelle 1906: 330 , syn. nov. Type locality: “Iles Arou, Wokan” (= Tanahbesar I. or Wokam I., Aru Islands, Indonesia), coll. O. Beccari (MCNG).

Diagnosis. This species has a characteristic shape of the antennal club, although this feature shows a rather wide variation probably depending on body size. Indo-Malayan and Australian specimens are very similar to each other, but exhibit a series of parallel variations. Coxollodes loriai differs from C. cyrtusoides and C. amamiensis from the only in the ultimate antennomere more or less longer than two previous ones combined (in C. cyrtusoides the ultimate antennomere not longer than two previous antennomeres) and also from C. reitteri from in the moderately narrow tibiae and more raised median carina on prosternum. The specimens of the type series and other specimens from New Guinea in general have somewhat larger body size: length of the lectotype of Pallodes loriai is 2.6 mm and the length of the holotype of P. opacus is 2.8 mm. Additionally, the Australian specimens usually have a shining dorsal integument and with distinct and deeper punctures.

Redescription. Length = 1.80–2.90: 1.80–2.10 (1.96 ± 0.10, n = 11) mm. Body broadly ovate, strongly convex: body length/elytral width = 1.28–1.61: 1.28–1.41 (1.34); greatest depth/elytral width = 0.58–0.64 (0.61). Posterior part of head, anteromesal portion of pronotum, scutellar shield and elytra dark reddish-brown to black; lateral portions and posterior edge of pronotum yellow; pygidium, ventral surfaces and legs varying from yellow to black. Dorsal vestiture very short and not visible under lower magnification; ventral vestiture consisting of short, fine setae. Head about 0.92× as long as wide. Eyes about 0.44× as long as head width. Temples about 0.18× as long as eye, more or less straight. Frontoclypeal suture distinct. Clypeus 0.37× as long as wide at base, sides subparallel to weakly concave apex. Labrum 0.36× as long as wide; sides rounded, anterior edge weakly, broadly rounded with very fine median incision. Antennal scape 1.75× as long as wide and 1.56× as long as pedicel; antennomere 3 about 2.0× as long as 4; club 1.16× as long as antennomeres 3–8 combined and 2.00× as long as wide; terminal antennomere as long as wide. Mandible strongly, abruptly curved at apex, which is obliquely bidentate and dorsally serrate; mola well-developed with a number of transverse ridges; prostheca a slender membrane lined with hairs; base of mola ventrally with densely setose lobe. Apical maxillary palpomere 2.5× as long as wide, widest near base with narrowly rounded apex. Mentum 0.45× as long as wide, widest subapically, apex slightly, broadly emarginate, with pair of broadly angulate anterior processes flanking shallow median emargination. Apical labial palpomere 1.5× as long as wide, broadly rounded at apex. Genal ridges sinuate and strongly converging, extending almost to posterior edges of eyes. Pronotum 0.42–0.47 (0.44)× as long as wide, widest at about posterior fourth, sides obliquely explanate, lateral margins very narrow, not visible for their entire lengths from above; anterior edge emarginate forming broadly rounded anterior angles; posterior angles almost right; posterior edge broadly rounded but sinuate on either side of scutellar shield; disc evenly convex; punctation very fine and sparse, punctures usually separated by more than two diameters; interspaces smooth and shiny. Prosternum 0.27× as long as mid length of procoxal cavity, with median carina extending beyond middle of prosternal process, which is 0.31× as wide as mid length of procoxal cavity, not curved behind coxae, and apically slightly emarginate, without distinct vertical or oblique wall. Scutellar shield 0.40× as wide as pronotum, with subacute apex; punctation about as fine and sparse as that on pronotum. Elytra 0.87–1.00 (0.93)× as long as wide and 2.05–2.60 (2.32)× as long as pronotum; lateral margins not visible from above; apices independently rounded, usually exposing part of pygidium; humeri weakly developed; disc convex; subsutural lines extending almost to anterior end; megapunctures distinctly larger than scutellar punctures, forming irregular, often incomplete rows and relatively widely separated within rows, punctation more confused posteriorly; micropunctures irregularly distributed; interspaces usually smoth or lightly sculptured and shiny. Epipleura oblique, wider anteriorly, gradually narrowed posteriorly and extending to posterior edge of abdominal ventrite 4. Anterior edge of mesoventrite on same plane as metaventrite, with low mesal carina extending to about middle and separating a pair of impressions; posterior edge of mesoventrite between mesocoxae deeply emarginate. Mesocoxae separated by about 0.5× longest longitudinal diameter of mesocoxal cavity. Metaventrite slightly convex; shortest distance between meso- and metacoxal cavities 0.31× as long as width of ventrite; discrimen about 0.50× as long as metaventrite, excluding anterior process; axillary spaces absent; posterior edges of mesocoxal cavities joined by fine, anteriorly curved line near base of anterior process of metaventrite, which is narrowly rounded at apex. Metanepisternum 4.7× as long as wide, widest near anterior end and narrowed posteriorly. Metacoxae separated by about 0.5× mid length (shortest diameter) of metacoxa. Protibia slightly expanded apically, its outer edge densely lined with serrations, each of which bears a short, stout, blunt spine; outer apex rounded with 5 long, dark, spines. Mesotibia ( Fig. 56 View FIGURES 50–58 ) moderately expanded, widest at apical third, then narrowed to apex, its outer edge lined with long, spines. Metatibia not or barely expanded, lined with long spines. Anterior faces of meso- and metatibia each with longitudinally oblique setal row. Basal pro- and mesotarsomeres moderately expanded and lobed. Metatarsomeres simple and metatarsus about equal in length to metatibia. Abdomen with ventrite 1 at lateral third slightly shorter than ventrite 2, with intercoxal process narrowly rounded, without postcoxal lines and with a double row of small pits behind metacoxae; ventrites 3 and 4 subequal to 1; ventrites 2–5 each with two transverse carinae near anterior edge; ventrite 5 1.22× as long as 4, broadly rounded in female and very slightly truncate in male. Pygidium with straight transverse basal carina, its apex broadly rounded in both sexes. Tergite VIII (anal sclerite) in male apically rounded. Tegmen ( Fig. 26 View FIGURES 24–42 ) 2.50× as long as wide, sides parallel for basal three-fourths, then slightly converging to broadly rounded apex; anterior tegminal strut 0.37× as long as body of tegmen, with narrowly truncate apex; penis ( Fig. 27 View FIGURES 24–42 ) slightly shorter than tegmen and 3.27× as long as wide, sides subparallel for basal four-fifths, then rather abruptly converging to narrowly rounded apex; anterior penile strut 1.32× as long as body of penis, slightly enlarged at apex. Ovipositor ( Fig. 43 View FIGURES 43–49 ) 1.36× as long as wide, somewhat flattened; paraprocts 1.79× as long as gonocoxites, which are 1.08× as long as their combined widths, with subparallel sides and broadly truncate, contiguous apices, without gonostyli.

Types. Lectotype of Pallodes loriai here designated (MCNG), male, “N. Guinea, Bujakori, Agosto 1890, Loria”, “ Pallodes Loriae ty. Grouv.”, “Typus” and 27 paralectotypes (MCNG, ZIN) with the same labels; lectotype of Pallodes opacus here designated (MCNG), female, “Isole, Aru, Wokau, O. Beccari, 1873”, “ Pallodes opacus ty. Grouv.”

Notes on synonymy. The specimens in the type series of Pallodes loriai (including lectotype) are somewhat smaller (with length 2.4–2.7 mm) than the lectotype of Pallodes opacus (with length 2.8 mm). Additionally, the types series of the first includes mostly specimens with very characteristic appearance and proportions of sclerites, while the lectotype of the second is more or less unicolourous brown, and also the latter has more regular longitudinal rows on elytra and wider mesotibia.

Distribution. Indonesia (Irian Jaya, Aru Islands), Papua New Guinea, Australia (Northern NSW to northern QLD).

Biology. The vast majority of Australian specimens have been collected in flight intercept traps and only one individual was found associated with a Ganoderma applanatum (Persoon) Patouillard (Basidiomycetes: Ganodermataceae ). The gut of one dissected specimen from northern NSW contained fungal spores only.
