Indothele amboli Kadam, Tripathi & Sherwood 2025, sp. nov.

Indothele amboli Kadam, Tripathi & Sherwood sp. nov. urn:lsid:zoobank.org:act: CC8A7C2A-DCD8-43AB-8CDC-8847C3ED511B Figs 1–4, 14, Table 1 Diagnosis Males of Indothele amboli sp. nov. resemble those of I. mala by the very long and slender embolus curving gently upward (Fig. 4A–B); metatarsus I ventral apophysis situated medially and consisting of a low retrolateral ridge (Fig. 2F), and distal end of metatarsus I with tiny protuberance situated basally, but can be distinguished by the following characteristics: (1) the embolus is much slender and the embolic tip longer (vs slightly broad and shorter tip in I. mala); (2) the tibial apophysis is elongate and narrow (vs short and broad in I. mala), and (3) the palpal tibia is incrassate (vs. unmodified in I. mala) (cf. Fig. 4A–C vs Fig. 12A–E). Females of Indothele amboli resemble those of I. rothi Coyle, 1995 by the weakly sclerotized spermathecal lobes, with each (opposing) median receptacle longer than lateral one, and with a correspondingly larger lobe on the median receptacle(s). However, they can be distinguished by the uniform size and shape of the receptacles (vs receptacles elongated in I. rothi) (cf. Fig. 4E vs Coyle 1995: figs 347–354). Etymology The specific epithet is a noun in apposition derived from the type locality.
