description: Gamasomorpha keri Eichenberger n. sp.
(Figs. 5–7)
Type material: Holotype male (PBI_OON 00031319): Indonesia: Sumatra: Jambi Province: Mount Kerinci, footpath to summit, W of Kersik Tua, 2160 m, evergreen hill forest, 17-18 February 2000, leg. P. Schwendinger (MHNG). Female paratype (PBI_OON 00031321): same locality, 1800-1980 m, evergreen hill forest, 16 February 2000, leg. P. Schwendinger (MHNG). Male paratype (PBI_OON 00011997), Sumatra: Jambi Province: Mount Kerinci, 2100 m, 14 November 1989, leg. Agosti, Löbl & Burckhardt (MHNG). Female paratype (PBI_OON 00031320), collected with male holotype (NMBE).
Etymology: The species epithet refers to the first part of the name of the Mount Kerinci in Sumatra which is the species’ type locality.
Diagnosis: Resembles G. asterobothros n. sp. but receptaculum (re) roundish with a posterior hump, glandular duct (gd) narrow, clearly longer than half the length of the receptaculum (figs. 7. E–F), and pars thoracica with two pairs of posterolateral tiny spikes (cps) and a ventral pair of rounded extensions (re), (figs. 5. G–H).
Description: Description based on 3 males and 6 females.
MALE: Body length 3.0 mm. Uniformly red-brown colored species, legs orange-brown (figs. 5. A–C). Similar to G. asterobothros: sternum with radial furrows of large, roundish, droplike pits between coxae I-II, II-III, III-IV (fig. 5. D), anterior margin with interrupted transverse groove (itg) (fig. 5. D; see fig. 5. F). Posterolateral edge of carapace with a pair of pits (cpp) (fig. 5. G–H). Eye group by radius to diameter of anterior lateral eyes narrower than clypeus (fig. 5. E). Abdomen scuto-pedicel region with paired curved scutal ridges (psr), (figs. 6. A–B), pedicel tube with small, dorsolateral, triangular extensions (pds), (figs. 6. A–B). Booklung covers (boc) quite large, ovoid, anterolateral edge unmodified (figs. 6. B–C). Male genitalia: Similar to G. asterobothros n. sp. with a long slender, lamellar embolus (em), adjacent to an embolic accessory appendage (ma) and a lamellar conductor (co) (figs. 7. A–C). With small conical extension (ce) (figs. 7. A–B).
FEMALE: Body length 3.6 mm. Distal apex of palpal tarsus with small pointed extension (fig. 7. D). Female genitalia: Without external features (fig. 6. D). Dorsal view (figs. 7. E–G): receptaculum (re) roundish with a posterior hump (ph) oriented ventrally, with almost circular secretory sac (ssa), globular appendix (gap) narrow, clearly longer than 0.5 times the receptaculum, pore field of receptaculum (pof) concentrated along globular appendix, with an anterior paddle-like sclerite (psc) and a nail-like process (na), with lateral sclerites functioning as muscle attachments (A1).
Distribution:
Sumatra, Mount Kerinci, Mount Tujuh (fig. 49. B).
Intraspecific variation: Sternal pits quite narrow and partly fused (fig. 5. F). Small pointed extension on distal apex of female palp reduced.
