Description

Total length: 8.1-9.7; carapace: 3.91-4.27 long, 2.31-2.48 wide; abdomen: 3.89-4.01 long, 1.78-1.89 wide. Body pattern in male similar to its female ( Kulkarni 2014) (Figs 6, 7). Cephalothorax. Cephalic and thoracic region in same plane. Lateral eyes encircled black, placed on prominent tubercles. AME separated by its diameter, PME less than its diameter. Smooth black pubescence on carapace. Thoracic region margined dark black. Chelicerae brown, long with three promarginal and four retromarginal teeth. Labium brown, semi-circular with slight corrugations; endites longer than wide, with wider proximal edge. Sternum brown, overall heart-shaped with straight margin at coxa II and folded inwards at coxae III and IV. Legs yellow coloured, femora black distally. Abdomen oval shaped, narrower than cephalothorax and slightly overlapping thoracic region when viewed laterally. Dorsum covered with greenish pubescence; venter black with thick yellow lines on the margin, sparsely covered with silver specks and whitish pubescence.

Cymbial dorso-basal process is shorter than half the cymbial width and perpendicular to cymbium longitudinal axis. Embolar base roughly circular. Long macrosetae on palpal metatarsus measuring half times its length. Morphometry of palpal organs is given in Table 1.

Remarks

The variation in body size and patterns in T. ventralis (see Jäger and Praxaysombath 2009) may be confused with T. sataraensis . Male palp and female epigyne examination can confirm the species identity. Furthermore, we found webs of T. sataraensis exclusively above and across stream water surfaces whereas webs of T. ventralis were found either adjacent to stream margins or away, among low vegetation; both observed in different localities.

Diagnosis

Tylorida sataraensis is closely related to T. ventralis but distinguished from all described Tylorida species by the following combination of characters: less swollen tegulum ventrally, longer embolar tip (Figs 1, 2, 3), presence of macroseta on palpal patella (Fig. 4). CDBP erect and pointed in T. sataraensis but slightly bent upwards near tip in T. ventralis (Fig. 5). Paracymbium arrow shaped, lateral margins curved, distal end folded inwards in former but with straight lateral margins and distal edge bulged at one end in latter species. Overall, T. sataraensis is large sized species than T. ventralis (Table 1).

Distribution

India, Maharashtra, Satara.
