Indopadilla bamilin Maddison, sp. nov. Figs 76-79

Type material.

Holotype male (specimen SWK12-1618, in UBCZ) from Malaysia: Sarawak: Mulu Nat. Pk., Clearwater Cave Trail, 4.0597°N, 114.8292°E to 4.0592°N, 114.8291°E, 60 m el. 14 March 2012 Maddison/Piascik/Ang WPM#12-027.

Etymology.

An arbitrary combination of letters, ungendered. Other names: In Maddison (2015b) and WPM’s lab notebooks the informal code for this species was “BVBML”.

Diagnosis.

Both embolus and RTA short and simple (Fig. 76 ). Other species with such a short embolus have a distinct TmA ( I. annamita , I. kahariana , I. redunca , I. sabivia ), which seems lacking in I. bamilin . First legs and body dark. None of the known females is an obvious match for this male in terms of markings or molecular phylogenetic placement, but also the unmatched females have longer copulatory ducts than would be expected for such a short embolus, or have a more dramatic ECP than expected for the simple RTA.

Description.

Male (based on holotype, specimen SWK12-1618). Carapace length 2.3; abdomen length 3.0. Carapace dark brown, slightly paler around fovea, with a few patches of pale scales on thorax (Figs 78 , 79 ). Clypeus dark, narrow; status of arthrodial membrane unclear, as chelicerae are somewhat sunken into the prosoma. Chelicerae vertical, brown, concave in front and with lateral ridge. Retromarginal teeth at least three, on long ridge. Palp femur dark; more distal segments pale. Embolus short, undivided (i.e., no TmA; Fig. 76 ). Tibia with dorsal lobe distally (Fig. 77 ). Endite rounded laterally, without corner or lobe. Legs strongly contrasting between black leg I and pale legs II-IV. First patella entirely black. Abdomen dark red in life, with longitudinal band of pale scales on each side broken as typical for the genus.
