Epidius longimanus View in CoL sp. nov.

( Figures 5 View Figure 5 (a–d), 6(a–c), and 8(c))

Type material

Holotype, Male (MNHN 9783), India, Tamil Nadu State, Kodaikanal (10.23°N, 77.48°E), no more data, E. Simon collection. GoogleMaps

Etymology

Latin, ‘longimanus’ refers to the relatively longer male palp.

Diagnosis

Distinguished from known congeners by the distinctive shape of E (thick, stout tip), C (tapering, screw-like tip; Figures 5 View Figure 5 (d), 6(a), and 8(c)) and absence of RTA ( Figures 5 View Figure 5 (d) and 6(a)). Females are distinguished by the globular S, and except for E. floreni sp. nov. by the deeply indented anterior margin of the epigynum ( Figure 6 View Figure 6 (b, c)).

Description

Male. Total length: 4.0; prosoma length: 2.1, width: 1.6. Leg I: femur 3.6, patella 0.9, tibia 3.4, metatarsus 3.3. tarsus 1.7. Prosoma yellow, without prominent markings or conspicuous setae. Opisthosoma light yellow, dorsally with inconspicuous brown spots. ALE = PLE> PME> AME. AER, PER recurved, eyes on brown-coloured protuberances. Chelicerae with 3 and 2 teeth on pro- and retromargin of fang furrow, respectively. Leg formula 1243. Palps as in Figures 5 View Figure 5 (d), 6(a), and 8(c), femur and tibia characteristically elongated, femur as long as tibia, furnished with 2 thick long spines and MTr, RTA absent. Bulbus ovoid, conductor with a screw-like tip, MA absent. Embolus stout, tapering.

Female. Total length: 6.0; prosoma length: 2.4, width: 2.1. Leg I: femur 3.6, patella 0.9, tibia 3.2, metatarsus 2.4, tarsus 1.2. In general similar to male. Epigynum without hood, anterior margin deeply indented, dual-chambered S connected by a C-shaped, thickwalled CD ( Figure 6 View Figure 6 (b, c)).

Distribution

Known only from Kodaikanal and Trichanophilai in India. This species and the next, Epidius mahavira sp. nov., appear to occur in the same two localities. This might be due to mislabeling.
