Gamasomorpha ophiria Eichenberger n. sp.

( Figs. 15–16 )

Type material: Holotype male ( PBI_OON 00012010 ): West-Malaysia: Johor: Gunung Ledang (= Mount Ophir ), Puteri Waterfalls , 2°21'22.2"N / 102°37'48.8"E, 80-130 m, rain forest near stream, 21 – 22 May 2004, leg. P. Schwendinger ( MHNG). Female paratype ( PBI_OON 00016053 ), collected with male holotype ( MHNG). Male paratype ( PBI_OON 00016052 ), collected with male holotype ( NMBE).

Etymolog y: The species epithet, an adjective, is composed of the name of the Mount Ophir in West-Malaysia which is the type location of this species.

Diagnosis: Resembles G. insomnia n. sp. but booklung covers small, ovoid, elevated from body surface (figs. 15. I–J), carapace with two pairs of posterolateral spikes (cps), (fig. 15. H) and carapace lateral margin with sharply pointed denticles (fig. 15. H).

Description: Description based on 2 males and 1 female.

MALE: Body length: 2.1 mm. Uniformly orange-brown colored species, legs pale orange (figs. 15. A–C). Sternum with radial furrows of large, roundish, droplike pits between coxae I-II, II-III, III-IV (fig. 15. D), anterior margin with interrupted transverse groove (itg) (fig. 15. D). Carapace with two pairs of posterolateral spikes (cps) (figs. 15. F, H); posterolateral edge with a pair of pits (cpp) (figs. 15. F, H); lateral margin straight from dorsal view. Eye group by radius to diameter of anterior lateral eyes narrower than clypeus (fig. 15. E). Abdomen scuto-pedicel region and pedicel tube unmodified (fig. 15. G). No detailed description on promarginal chelicerae setae, serrula, grooves on lateral margin of sternum, trichobothria hood structure, tarsal organ and scopula between claws. 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. 16. A–E). Mesal embolic accessory appendage (ma) with a transparent, denticulated seam (ds) (figs. 16. A–C). Conical extension unincisive (ce) (figs. 16. A–C).

FEMALE: Body length 2.3 mm. Female genitalia: Ventral view (fig. 16. D): Without external features.

Distribution: Known only from the type location, Mount Ophir, West-Malaysia (fig. 49. A).
