NEPAL: 3 larvae, Bagmati Zone, East Rapti River, 27.571631, 84.668756, h— 230 m a.s.l., 27.i.2014, Chertoprud M. V. leg.— IN Nepa 16 Torsp 1 [NMNH NASU].
Diagnosis. This species can be distinguished from other Torleya species by the following combination of characters: Larva: (i) dorsal surface of body covered by long hair-like setae (Fig. 10A; fig. 1 in Allen & Edmunds 1963); (ii) maxilla with rudimentary palp (fig. 13 in Allen & Edmunds 1963); (iii) anteromedian emargination very shallow, almost absent (fig. 14 in Allen & Edmunds 1963); (iv) labium highly reduced (fig. 17 in Allen & Edmunds 1963); (v) abdominal segment VIII with a unique shape and setation (Fig. 10A, C; fig. 1 in Allen & Edmunds 1963; fig. 1 in Jacobus et al. 2007); (vi) posterolateral projections of segment IX extremely elongated (Fig. 10A, C; fig. 1 in Allen & Edmunds 1963); (vii) tarsal claw with distinct distal palisade of denticles (Fig. 10B; fig. 15 in Allen & Edmunds 1963); (viii) lateral margins of abdominal segments IV–VIII with short stout setae; stout setae on segment VIII pass over acute posterior projection (fig. 1 in Allen & Edmunds 1963); (ix) paired submedial projections on abdominal terga are absent (Fig. 10C; fig. 1 in Allen & Edmunds 1963); (x) gills III–VI with outer posterolateral protuberances, gill III not covering following gills entirely (figs 1, 16 in Allen & Edmunds 1963). Male imago: (xi) penis short, lobes apically rounded (fig. 2 in Jacobus et al. 2007); (xii) dorsal projection of penis small, rounded, with broad apical cleft (figs 2, 4 in Jacobus et al. 2007) (xiii) genital forceps segment II robust, with relatively straight lateral profile, not expanded apically and segment III subovoid (fig. 2 in Jacobus et al. 2007); (xiv) abdomen with light general coloration and purple shading, lacking a prominent, middorsal, longitudinal stripe (figs 3, 4 in Jacobus et al. 2007).
Distribution. India (Allen 1980, Jacobus & McCafferty 2003, Jacobus et al. 2007, new data), India-China border region (new data), Malaysia (Jacobus et al. 2007), Nepal (Allen & Edmunds 1963, new data), Thailand (Wang & Sites 1999; Jacobus et al. 2007) and Vietnam (Jacobus et al. 2007).
Remarks. The larva of this species was adequately described and illustrated from Nepal by Allen & Edmunds (1963) and from Thailand by Wang & Sites (1999) (as Crinitella permkami Wang & Sites, 1999, junior synonym). Larvae of this species already were reported from Kashmir, and the adult description and details of species variability were provided by Jacobus et al. (2007). Following Jacobus & McCafferty (2008), we consider Crinitella Allen & Edmunds, 1963 as a junior synonym of Torleya Lestage, 1917. Ogden et al. (2009: figs 1, 2) could not confirm monophyly of Crinitella + Torleya, however, based on their partial sampling of these genus groups.
The other Indomalayan species of Torleya include T. dibruensis sp. nov., T. lacuna (Jacobus, McCafferty & Sites, 2007), T. longforceps (Gui, Zhou & Su, 1999), T. lutosa Kang & Yang, 1995, T. naga Jacobus & McCafferty (in Jacobus et al.), 2004, T. nepalica (Allen & Edmunds, 1963) and T. simbalbarensis sp. nov.
