Genus Sudra Distant

Type species. Sudra notanda Distant , by original designation.

Diagnosis. Head produced in front of eyes, narrowed anteriorly and apex reflexed. Crown rounded and slightly convex. Ocelli mesad of and almost at midlength of each eye. Callosities look like two transparent spots on posterior margin of crown. Fontal sutures not reaching ocelli but end close to them. Face elongate, laterally obliquely straight in front of eyes to near apex. Frontoclypeus parallel sided below eyes. Clypellus broad basally, gradually narrowed distally, before apex expanded and convexly rounded apically, slightly extending beyond genal curve. Lora narrow long, ending dorsally at transclypeal sulcus. Labium reaching posterior margin of mesosternum. Pronotum centrally about as long as crown, disc obliquely striate, striae discontinuous, anterior margin roundly truncate, posterior margin subangularly sinuate, lateral margins carinate. Combined length of mesoscutum and scutellum much longer than pronotum and crown, extending beyond clavus or at least beyond distal 0.75 length of clavus, narrowed, and spine-like apically, blade-like in lateral view, with prominent dorsal median carina on scutellum. Hind wing costal margin with 7 stout setae in proximal half ( Fig. 14K, L ). Pro tibiae dilated. Meta femur distal macrosetae 2+1+1. Meta tibial macrosetal row PD 11, AD 12±1, AV 19 setae, AV row present at distal 0.75 length and distal three setae elongated. Metabasitarsomere plantar surface with 3 stout long setae in oblique row distally in addition to a few thin narrow setae and distal transverse row with 6 platellae flanked by one seta on either side ( Fig. 15G ). Male genital capsule depressed, partially withdrawn into segment VIII. Pygofer posterior margin sclerotized and with tooth-like serrations, each tooth bearing one thin seta, with ventral process longer than subgenital plates. Subgenital plates articulated with valve, lateral margins convexly rounded, apex conically rounded. Style as in Hatigoria , not exceeding connective in dorsal view, with setae at apex of apophysis. Connective articulated with aedeagus longer than broad, anteriorly bilobed. Aedeagus with prolonged atrium, dorsal apodeme well-developed, shaft tubular without processes, with apical gonopore, dorsal surface with transverse rugae.

Remarks. Kramer (1964) redescribed the genus including the type species and also described one new species from Borneo. However, he mistook the male pygofer ventral process for the style and considered the true style as part of connective. Tang & Zhang (2023) treated the gnus Pseudosudra as a junior synonym of Sudra and Sudra insularis Schmidt as a junior synonym of S. notanda , recognized three species in the genus, namely S. manonga Kramer (from West Borneo), S. notanda Distant (from Myanmar, Thailand, China Indonesia) and S. borneensis Schmidt. The genus is recorded for the first time from India represented by a new species and the genus is now found in India, Myanmar, Thailand, Indonesia (Sumatra, Borneo).
