description: Gamasomorpha petoteca Eichenberger n. sp.
(Figs. 8–10)
Type material: Holotype male (PBI_OON 00016054): West-Malaysia: Perak: limestone hill 500 m S of Perak Tong Cave Temple, 4°38'35.8"N, 101°05'48.1"E, 6 km N of Ipoh, 70 m, secondary scrub, 20 June 2004, leg. P. Schwendinger (MHNG). Female paratype (PBI_OON 00016055), collected with male holotype (MHNG). Male paratype (PBI_OON 00016058), collected with male holotype (MHNG). Male paratype (PBI_OON 00016056), collected with male holotype (NMBE). Female paratype (PBI_OON 00016057), collected with male holotype (NMBE).
Etymology: The species epithet is arbitrarily composed of the first two letters each of the name of the type location: Perak Tong Cave Temple.
Diagnosis: Resembles G. asterobothros n. sp. but mesal embolic accessory appendage (ma) with a transparent, denticulate seam (ds), (fig. 10. C, E) and lateral margin of carapace with small, pointed denticles (fig. 8. F).
Description: Description based on 12 males and 9 females.
MALE: Body length 2.1 mm. Uniformly orange-brown colored species, legs pale orange (figs. 8. A–C). Similar to G. asterobothros: Sternum with radial furrows of large, roundish droplike pits between coxae I-II, II-III, III- IV (fig. 8. D), anterior margin with interrupted transverse groove (itg) (fig. 8. D). Carapace with three pairs of posterolateral spikes (cps), (figs. 8. F–G), lateral margin of carapace with pointed denticles that may be partly reduced (fig. 8. F), posterolateral edge with a pair of pits (cpp) (figs. 8. F–G). Eye group by radius to diameter of anterior lateral eyes narrower than clypeus (fig. 8. E). Abdomen scuto-pedicel region with paired curved scutal ridges (psr) (fig. 9. A), pedicel tube with small, dorsolateral, triangular extensions (pds) (fig. 9. A). Booklung covers (boc) quite large, ovoid, anterolateral edge unmodified (fig. 9. D). 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. 10. A–C). Conical extension (ce) unincisive (figs. 10. A–B).
FEMALE: Body length 2.4–2.7 mm. As in male except as noted. Slightly larger than male. Opisthosoma more round. Postepigastric scutum not fused to epigastric scutum. Booklung covers may be stronger pronounced (fig. 9. D). Female palp spines absent, 3 trichobothria on tibia.
FEMALE GENITALIA: Ventral view (fig. 9. B): Without external features. Dorsal view (10. F–H): receptaculum (re) and secretory sac (ssa) ovoid, globular appendix (gap) about half the length of receptaculum, pore field of receptaculum (pof) concentrated at posterior end of globular appendix, with an anterior paddle-like sclerite (psc) and a nail-like process (na), with lateral sclerites functioning as muscle attachments (A1).
Distribution: West-Malaysia, Perak (fig. 49. A).
Intraspecific variation: Carapace lateral margin pointed denticles vary in size, number and distribution. Booklung covers may be hardly visible (fig. 9. C). Small pointed denticles on lateral margin of carapace partly reduced.
