ONOMASTUS KAHARIAN SP. NOV.
( FIGS 5A–E, 6A–F)
Diagnosis: Males are readily separated from O. patellari s and O. indra by the absence of TA2. Separated from O. rattotensis , O. nigricauda , O. quinquenotatus , and O. pethiyagodai by the presences of a broad conductor ( Fig. 6D). Separated from O. complexipalpis , O. kanoi , and O. nigrimaculatus by the scoop-like MA and shape of C ( Fig. 6D). Females could be separated from all other Onomastus by the presence of semicircular epigynal fold and C-shaped CD ( Fig. 5D, E).
Male holotype: Total length: 3.4; prosoma length: 1.5, width: 1.0. Leg I: femur 1.6, patella 0.5, tibia 1.7, metatarsus 1.1, tarsus 0.5. All spiders are whitish to pale yellow in alcohol, no markings. Prosoma oval, almost as wide as long, laterals darker. Opisthosoma oval, longer than wide, lighter in colour. Legs pale yellow, laterally without dark markings; might be a result of preservation. All eyes except AME surrounded by dark rings. Chelicerae with pro- and retromarginal teeth, number not examined. Leg formula 4132. Leg spination: leg 1: metatarsus V 2-1-2; tibia V 2-2-3; femur D 0-0-1, P 0-1-2. Palp as in Figures 5A, B and 6A–F.
Female paratype: Total length: 3.5; prosoma length: 1.4, width: 1.0. Leg 1: femur 1.4, patella 0.4, tibia 1.5, metatarsus 1.1, tarsus 0.4. Morphology as above, except for the lighter coloured prosoma, opisthosoma and leg spination given below. Leg spination: leg 1: metatarsus V 2-1-2; tibia V 3-2-2; femur D 1-1-1. Epigynum and vulva as in Figure 5C–E.

Khao Luang NP, 8°43′25.2″ N, 99°40′7.7″E, 355 m, 10–12.x.2003 (ATOL expedition 2003), 1♂ 1♀, deposited in USNM GoogleMaps .
( FIG. 7A–E)
Diagnosis: Onomastus kanoi is readily distinguished from all known species of Onomastus except for O. complexipalpis by the large disk-shaped palpal conductor in the males ( Fig. 7A–D). The conductor of O. kanoi is relatively smaller than that of O. complexipalpis ( Fig. 7D). The female of O. kanoi is unknown. However, I predict that the CD of O. kanoi females would be longer than that of all other Onomastus , but shorter than that of O. complexipalpis .
Male: Total length: 5.2; prosoma length: 2.0, width: 1.5. Leg I: femur 2.0, patella 0.6, tibia 2.0, metatarsus 2.0, tarsus 0.6. For a detailed description see Ono (1995).
