Hishimonus thapai Viraktamath & Murthy, 2014, sp. nov.

Hishimonus thapai sp. nov.

Figs 29–30, 193–204.

Head and thorax greenish yellow, crown of vertex with irregular light brown to dark brown spots. Face and pronotum mottled with dark brown. Median spot on forewings not so distinct.

Male genitalia. Pygofer in lateral view longer than its height, posterior margin broadly rounded, macrosetae confined to posterior half. Valve with broadly rounded corners, 2.75 times as wide at base as long medially. Subgenital plates abruptly narrowed to terminal fingerlike process, terminal process about 0.33 as long as total length. Style about 3.5 times as long as wide at base; preapical lobe well-developed, with a few hairlike setae; apophysis acute, long, directed laterally. Stem of connective stout, shorter than arm. Aedeagal shafts diverging right from base, directed posteriorly, broadly lamellate over caudal half in lateral view, with short fingerlike process at apex turned abruptly anteriorly; pair of elongate acute processes arising basally from posterior surface of shafts extending beyond mid-length of shafts.

Female genitalia. Seventh sternite 2.5 times as wide at base as long medially, posterior margin concave but medially produced posteriorly with median V-shaped notch, posterolateral angles conically rounded.

Measurements. Male 4.00 mm long and 1.23 mm wide across eyes. Female 4.10–4.15 mm long, 1.30 mm wide.

Material examined. HOLOTYPE ♂, NEPAL: Kathmandu, 23.viii–5.ix.1978, V.K. Thapa (UASB). PARATYPES: 1 ♂, 2 ♀ data as for holotype; 1 ♂, 4 ♀, Kathmandu: Kokani, Takha, 28.x–14.xi.1978, V.K. Thapa (BMNH, NPC, UASB).

Remarks. Externally H. thapai and H. gillespiei resemble each other closely but can be distinguished by the coloration of the median spot on the forewings: the anterior margin of the median spot is dark brown in H. gillespiei where as it is not so in H. thapai. They also have different male genitalia: the aedeagus of H. thapai has basal processes whereas in H. gillespei they are absent. The females of the two species may also be diagnosed by the shape of the posterior margin of the seventh sternite. In H. thapai the posterior margin is shallowly excavated in the middle with lateral rounded lobes whereas in H. gillespiei the excavation is deeper and larger in the form of a trough. Both the species are sympatric.
