Descriptions

Larva. Described by Selvakumar et al. (2014). Additional characters: Labrum with simple setae forming transverse field all over labrum width, with feathered setae located distad of this field. Abdominal terga without bifurcate setae [in contrast to T. (D.) eloisae]; terga I–IV nearly without setae; tergum V with few hair-like setae on posterior margin submedially; tergum VI with pair of rows of longer setae; tergum VII with few larger pointed setae, terga VIII–IX with few setae and few small denticles on posterior margins (Figs 141–142). Setae on lateral margins of abdominal segments VII–IX long and slender, on posterolateral spines of these segments short and stout (Fig. 137). Posterior margin of sternum IX evenly convex (in male with small protogonostyli by sides) (Fig. 137). Tergalii III–IV stretched anteriorly, each with cleft on apex (Figs. 18–19) [in contrast to T. (D.) eloisae, which has no cleft on tergalius IV]; tergalii II–III with two-branched ventral lobe, tergalius IV without ventral lobe.
