(Figures 1B, 5A–C)
Diagnosis
Males of C. cylindriformis sp. nov. closely resemble those of C. cultrata sp. nov. in having the petal-shaped RTA; the cylindrical base of embolus freely emerging from the tegulum (cone-shaped in C. cultrata sp. nov.); the embolus being shorter and more slender (embolus blade-shaped and more elongate in C. cultrata sp. nov.). Males of both species possess a conspicuous, conical tubercle situated on the dorsal side of cymbium (Figure 5C,E,F).
Type material
Holotype. ♂, Malaysia, Borneo, Sarawak State, Serian District, Penrissen Road 12 miles (19 km) of Kuching, Sernonkok Wildlife Rehabilitation Centre: Nursery Centre of the Forest Department, 20–50 m, 8 December 1987, C. Lionhard leg. (MHNG, Sar-87/62).
Etymology
The specific epithet is a derived combination of Greek and Latin words (Gk. κυΛΙΝδΡΟϛ = cylindrus = cylindrical), referring to the shape of the embolic base.
Description
Male (holotype). Total length 5.8; prosoma 3.4 long, 3.0 wide; opisthosoma 3.2 long, 1.4 wide. Prosoma ovoid, convex, in profile highest mid-distance between PME and longitudinal fovea; integument smooth, devoid of hairs; carapace yellowish brown; chelicerae brown, with three promarginal and three smaller retromarginal teeth; labium and gnathocoxae pale brown; sternum pale yellow. Eye sizes and interdistances: AME 0.10, ALE 0.10, PME 0.20, PLE 0.18, AME–AME 0.10, AME–ALE 0.10, PME–PME 0.40, PME–PLE 0.32; MOQ: 0.30 long, 0.32 anterior width, 0.66 posterior width. Legs uniform pale yellow; scopulae on tarsi and metatarsi I–II distinct, in III–IV sparse. Leg formula 4213. Leg measurements: leg I 5.2 (1.6, 0.8, 1.2, 1.0, 0.6); leg II 6.8 (2.2, 0.8, 2.0, 1.2, 0.6); leg III 6.4 (1.6, 1.4, 1.4, 1.4, 0.6); leg IV 8.4 (2.4, 0.8, 2.2, 2.0, 1.0).
