Genus Hatigoria Distant

Type species: Hatigoria praeiens Distant , by original designation.

Diagnosis. Crown abruptly narrowed and produced in front of eyes, basal half with median and sublateral carinae, distal projection with dorsal and ventral carinae and lateral ridges. Labium short not exceeding fore coxae. Pronotum without lateral carinae or ridges. Hind wing costal margin with 7 stout setae in proximal half ( Fig. 13E, F ). Mesonotum about as long as pronotum. Meta femora with distal macrosetae 2+1+1+1; metabasitarsomere with hair-like setae on plantar surface, distal transverse row with 9 platellae flanked by one stout long seta on either side ( Fig. 15B ).

Description. Head produced in front of eyes, narrowed and directed dorsally in distal half, with dorsal, ventral and lateral prominent carinae. Ocelli on crown near anterior margin of eyes, frontal sutures end in front of ocelli. Crown anterior to ocelli with median carina and sublateral carinae arising in mesal margin in front of ocelli and becoming lateral and forming lateral margin of crown, posterior area with two faint oblique lateral ridges. Clypellus broad basally but widest a short distance from base and then slightly narrowed extending much beyond genal curve and medially slightly concave. Antennal ledges prominent and protruding; frontoclypeus more or less parallel sided. Labium short not exceeding front coxae. Face somewhat broad, anteriorly subtriangular. Pronotum somewhat depressed sublaterally in anterior half, posterior margin concave medially, lateral margins rounded without carina, obliquely sinuate. Hind wing costal margin with 7 stout setae in proximal half( Fig. 13E, F ). Mesonotum subtriangular, about as long as pronotum. Fore tibiae not dilated, Meta femora with distal macrosetae 2+1+1+1, Meta tibiae PD 12, AD 10, AV 20, distal five setae in row AV a little stouter and longer than remaining ones; plantar surface without stout seta but covered by thin hair-like setae, distal transverse row with 9 platellae flanked on either side by a stout long seta ( Fig. 15B ).

Male genitalia. Pygofer elongate, about 2× as long as width at midlength in lateral view, slightly longer than subgenital plates, with ventral process bifurcated, lateral fork short, mesal fork long, abruptly curved inwardly near 0.33 length and crossing over its counterpart at mid line. Subgenital plates longer than basal width, lateral margins slightly convexly rounded, apex conically rounded. Style apophysis lobe like, not extending beyond posterior margin of connective, anterior part more than 3× as long as apophysis, lacking lateral lobe, posterior apex with a few apical setae. Connective plate-like articulated with aedeagus. Aedeagus with atrium and dorsal apodemes though short well-developed, shaft tubular, with lateral marginal transverse striations, without processes, gonopore apical on dorsal surface.

Remarks. Tang & Zhang (2021) revised the genus and dealt with three species from the Oriental region, one of which was new. Here one new species in addition to the type species is described. Three species of Hatigoria namely, H. praeiens , H. longistyla and H. zhangi sp. nov. are very uniform in the following characters: shape of the anterior process of the crown, metabasitarsomere without macrosetae on plantar surface (information on this in the type species unknown), male pygofer ventral process distally bifurcated. However, H. sauteri Jacobi has a quite atypically shaped crown, an unbranched pygofer ventral process and a stout spine on the plantar surface of the metabasitarsomere.
