Notes

Zonstein & Marusik (2019: 88) considered the type locality of Filistata marginata   as “ Japan, Honshu, Akita Prefecture, Senboku”. This was apparently a mistake: H. Ono (in litt.) informed us that the original text in Komatsu (1936) reads “Distribution: Taiwan. In August of 1935, Mr. Kyukichi Kishida found this spider in a hotel at Tainan where he stayed. […] Afterwards, Mr. Izumi Kayashima announced that this spider is very common in houses in Taihoku.” Taihoku was an administrative region of the island while it was under Japanese rule, and corresponds to modern-day Taipei. Apparently, the old Japanese kanji ‘tai’ was misread by Zonstein & Marusik as ‘sen’, causing the confusion. Thus, the correct type locality of this species is Taiwan, Tainan. This species is cited in books on Taiwanese spiders ( Kayashima 1943; Lee 1966), supporting this view. H. Ono (in litt.) kindly informed us that “after the death of Dr. Kishida in 1968, no specimen has been found, which he presumably held”, and thus we may consider that the type specimens of F. marginata   have been lost. We have examined specimens from Taiwan, Pingtung (50 km to the south of Tainan) whose habitus morphology fits well with Komatsu’s (1936) illustration, thus ascertaining the identity of this species. Since this is the only filistatid known to occur in Taiwan and the original illustrations match our specimens, this name can be objectively applied to this species, precluding the need for a neotype (see International Code of Zoological Nomenclature, article 75.1). Wang (1987: fig. 1i) was the first to illustrate the female genitalia of this species, showing the single pair of receptacles with a trilobulate structure; however, the locality of the illustrated specimens is unclear.

The types of Filistata bakeri   are in a bad state of preservation, and apparently have dried at some point. The palp of the holotype is deformed, especially the sperm duct; the colours are faded, but Berland’s illustration match the colour pattern of fresh specimens examined by us. Berland (1938) mentions a male paratype, but the two vials we saw contain only one male, six females and one immature. Records of this species by Berland (1942) from Austral Islands could not be checked and are not included in the map; his report of this species for Christmas Island probably refers to L. gibsonhilli   . Lehtinen (1967) included two species in his Pritha bakeri   group: Filistata bakeri   from Vanuatu and a species from Taiwan he thought to be new (his revision did not account for F. marginata   ). We here show that specimens from both islands are conspecific; specimens from Taiwan ( Fig. 19F View Fig ) and Vanuatu ( Fig. 19C View Fig ) show similar female genitalia, and the differences observed in males ( Fig. 18D, G View Fig ) are due to the bad preservation of the holotype of Filistata bakeri   .

Diagnosis

The male is most similar to L. incerta   sp. nov. in the paraembolic lamina divided in two parts, with a rounded apex near the embolus; it differs by strong fimbriations in the paraembolic lamina and the bulb with a median constriction ( Fig. 18 View Fig ) (vs smaller fimbriations, bulb without clear median constriction). Females are unique among all filistatids by the genitalia with a single pair of stalked, trilobate receptacles ( Fig. 19 View Fig ).

on the proximal and distal ends of tibiae III–IV. Abdomen brown, with faint light brown chevron posteriorly, and a large patch of white setae anteriorly on dorsum.

HABITUS. Anterior margin of the carapace subrounded, with unsclerotized tip. Eye apodemes present. Sternum subrounded, sigilla not visible.

MEASUREMENTS. Total length 2.49. Carapace length 1.19, width 0.93. Clypeus length 0.23. Eye diameters and interdistances: AME 0.07, PME 0.09, ALE 0.13, PLE 0.10, AME–AME 0.02, PME–PME 0.10. Sternum length 0.73, width 0.65. Palp: femur length 0.56, height 0.17, tibia length 0.32, height 0.19. Leg I: 6.20 (1.59, 0.40, 1.80, 1.55, 0.86). II: 4.21 (1.21, 0.35, 1.14, 0.99, 0.52). III: — (0.99, 0.30, 0.87, x, x). IV: 4.85 (1.32, 0.35, 1.26, 1.31, 0.61). Abdomen: length 1.58, width 0.82.

LEG MACROSETAE. Mt I 1a.vr.

PALP ( Figs 18 View Fig , 20–21 View Fig View Fig ). Cymbium horseshoe shaped, bulb enlarged, with a median constriction, sperm duct N-shaped with a single coil, prolateral excavation very large occupying most of the tegulum, paraembolic lamina large, in two parts, with fimbriations proximally and digitiform distally, ending close to the apex of the embolus, embolus short and slightly curved.

State of the specimen: good, lacking some setae; left palp and right leg I dissected.

Female (from Parque Nacional La Cangreja, San Jose, Costa Rica, INBIO 79582)

COLOURATION. As in male, except for lack of brown markings on carapace and chevron in the abdomen.

HABITUS. Eye apodemes present. Sternum subrounded.

MEASUREMENTS. Total length 3.86. Carapace length 1.25, width 1.02. Clypeus length 0.28. Eye diameters and interdistances: AME 0.06, PME 0.08, ALE 0.12, PLE 0.11, AME–AME 0.02, PME–PME 0.09. Sternum length 0.86, width 0.67. Palp: femur length 0.72, height 0.30, tibia length 0.39, height 0.23. Leg I: 4.89 (1.28, 0.37, 1.31, 1.13, 0.80). II: — (1.08, 0.35, 0.88, x, x). III: — (0.92, 0.35, 0.70, x, x). IV: 4.32 (1.27, 0.39, 1.11, 0.97, 0.58). Abdomen: length 2.56, width 1.63.

LEG MACROSETAE. Absent. Calamistrum with three rows with 5-5-6 setae.

EPIGASTRIC FURROW. Adorned with thick setae.

ENDOGYNE ( Figs 19 View Fig , 22 View Fig ). Median receptacles absent, lateral receptacles on a short stalk, trilobulate, sclerotized, with several glandular pores restricted to the proximal lobe. State of the specimen: good, genitalia dissected.

Variation

Female seminal receptacles may be fully sclerotized or hyaline ( Fig. 19 View Fig ); perhaps this may depend on the maturity or reproductive status of the females. Males (N = 5): total length 2.19–2.79 (2.55), carapace length 0.99–1.2 (1.15), femur I length 1.31–1.59 (1.49), tibia I length 1.57–1.8 (1.72), femur/carapace ratio 1.18–1.34 (1.29). Females (N = 5): total length 2.73–4.96 (3.79), carapace length 1.17–1.8 (1.42), femur I length 1.1–1.58 (1.36), tibia I length 1.13–1.72 (1.4), femur/carapace ratio 0.88–1.02 (0.96).

Distribution

Widely distributed in tropical Polynesia, with other records in Taiwan, Philippines, New Guinea, Vanuatu, and in continental America from Mexico to Brazil ( Fig. 1D View Fig ).
