ONOMASTUS INDRA SP. NOV.

( FIG. 4A–E )

Holotype: ♂ from India, Kodaikanal , Grade, 1600 m, 30.iii.1962, leg. E. S. Ross and D. Q. Cavagnaro. Deposited in CAS.

Paratypes: 2♀ from the same locality as the holotype. Label data as above. Deposited in CAS .

Etymology: Indra is the deity of war in the Hindu religion. I use the species epithet as a noun in apposition.

Diagnosis: Separated from all other species except for O. patellaris by the occurrence of TA 2 in males. Separated from O. patellaris by the shorter, stouter TA1 and TA2 ( Fig. 4A, B ); further, the end of TA2 is in the shape of an upward hook in O. patellari s ( Fig. 17A ).

Male holotype: Total length: 3.8; prosoma length: 2.0, width: 1.3. Leg I: femur 1.6, patella 0.3, tibia 0.8, metatarsus 0.7, tarsus 0.3. 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. Palps as in Figure 4A and B .

Female paratype: Total length: 4.4; prosoma length: 2.0, width: 1.3. Leg 1: femur 1.6, patella 0.6, tibia 1.4, metatarsus 1.2, tarsus 0.6. Morphology as above, except for the lighter coloured prosoma and 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 4C–E .

Other material examined: None.
