Diplectrona indica ( Mosely 1931)

( Figs 1–5 )

Diagnosis. This species is similar to Diplectrona jacobsoni Ulmer 1909 , D. ismene Malicky 2002 , D. hermione Malicky & Chantaramongkol 2002 , and D. eurykleia Malicky 2002 as the dorsal views of the male genitalia are very similar in all these species, especially similar to D. ismene . However, the lateral lobes of tergum X are twisted outwards in D. indica at 2/3rd of their length in dorsal view and are longer than the mesocaudal lobes; whereas the lateral lobes, though twisted, are almost equal to the mesocaudal lobes in length in dorsal view in D. ismene .

Description. Adult male color in alcohol dark brown, wings light brown, antennae and maxillary palps infuscate, dorsum of head and thorax black. Length from tip of head to apex of folded forewings about 7.25 mm; maxillary palps each 2.25 mm long, segment II longer than III, V as long as I–IV combined; labial palps each 0.75 mm long. Length of each forewing about 6 mm, venation typical for genus; Sc and R1 running independently to wing apex; each hind wing about 5 mm long, Sc thickened, R1 bowed subapically, fork I present.

Male genitalia ( Figs 1–5 ). Abdominal segment IX annular, anterolateral margins slightly convex; posterior margin nearly straight, produced ventrolaterally over bases of inferior appendages. Tergum X divided into paired mesocaudal and lateral lobes; mesocaudal lobes each apically rounded and slightly convergent in dorsal view, apicomesally separated to mid-length; enclosed by projecting lateral lobes. Lateral lobes each broad basally in lateral and dorsal views, distally narrow, angulate, slightly constricted, twisted, and divergent preapically. Inferior appendages long, stout, slender; each with basal segment about 3 times as long as apical one; apical segment small, curved mesad sub-basally and pointed apically. Phallus tubular, elongate, slightly angled near base, with 2 pairs of elongate dorsolateral spines and ventral scoop-like structure possibly representing phallicata.
