Diagnosis
Keosarima konkakinha gen. et sp. nov. can be recognized by the moderately elongate shaft of the laterodorsal process of the periandrium, reaching nearly to halflength of the aedeagus (sp – Fig. 8H View Fig ) and the lateroventral process of the aedeagus reaching to the basal fourth of the aedeagus (lvp – Fig. 9H View Fig ).
Differential diagnosis
The new species is close to Keosarima armillata Constant gen. et sp. nov. but it shows a much shorter shaft of the laterodorsal process of the periandrium, limited to about halflength of the aedeagus (reaching nearly to the base of the aedeagus in K. armillata ), and the longer lateroventral process of the aedeagus less strongly sinuate and reaching to the basal fourth of the aedeagus (more sinuate and reaching to basal third of the aedeagus in K. konkakinha gen et sp. nov.).
Etymology
The specific epithet ‘ konkakinha ’ refers to the type locality of the species: Kon Ka Kinh National Park in Central Vietnam.

Vertex medium brown, slighlty darker along anterior margin, and with obsolete median carina yellowish brown; 2.0 × as broad as long in midline, weakly constricted in middle; disc moderately concave; anterior margin slightly, angularly projecting anteriad; posterior margin rather deeply concave; all margins elevated. Frons brown densely covered in small yellowish mottling, with more or less distinct transverse yellowish marking in middle; row of yellowish tubercles along lateral margins, larger yellowish spots along fronto-clypeal suture; convex, smooth with complete median carina, peridiscal carina obsolete. Genae yellowish brown, distinctly paler than vertex and frons, with small slightly darker area above ocellus; anteroventral angle not projecting anteriad. Clypeus triangular, convex, smooth with distinct meadian carina; anteclypeus yellowish brown with apical portion darker; postclypeus blackish brown. Labium yellowish brown with last segment longer than broad, slightly shorter than penultimate. Antennae with scape short, ring-shaped, dark brown, and pedicel bulbous, brown.
THORAX ( Fig. 7A, C–E View Fig ). Pronotum brown with weak, paler, yellowish median line; subtriangular, projecting anteriorly; smooth with anterior margin carinate and some yellowish tubercles in lateral fields, and pair of impressed points on each side of midline; lateral fields very narrow behind eyes; paranotal lobes brown, pale yellowish under eye and with strong black marking along ventral margin, with small yellowish tubercles, posteroventral angle rounded. Mesonotum brown, with carinae marked with paler colour, smooth, weakly convex with shallow depression before scutellum; sublateral (peridiscal) carinae incomplete but rather distinct, some pale tubercles in angles. Tegulae brown.
TEGMINA ( Fig. 7A–D View Fig ). Brown with most veins slightly paler, main veins more elevated than cross-veins; distinctly convex, and about 2.2 × as long as wide, with distinct lateral hump including vein ScP+RA slightly before basal ¼; distinct, brown epipleuron; clavus closed, reaching 4 /5 of tegmen length. Venation: as in genus description.
HIND WINGS ( Fig. 7F View Fig ). Blackish brown; veins darker than background, generally black, sometimes marked with red; well developed, with three distinct lobes ( Sarimini type) more or less equal in width; indentation between ScP-R-MP-Cu and Pcu-A1 lobes rather deep. Venation: as in genus description.
LEGS ( Fig. 7A–E View Fig ). Generally brown, paler than tegmina; darker rings on profemora (basal and anteapical), wide one about midlength of pro- and mesotibiae, and anteapical on metafemora; pro- and mesotibiae blackish apically; metatibiae darker basally; all spines of posterior legs black apically. Anterior and median legs slightly flattened dorsoventrally, tibiae more slender than corresponding femora; posteroventral margin of pro- and mesofemora with row of minute teeth; tarsi yellowish brown, pro- and mesotarsi rather elongate. Metatibiae with two lateral spines in distal half and six apical spines. Metatarsi moderately short with first segment about as long as combined length of remaining segments. First metatarsomere with two latero-apical and seven intermediate spines arranged in arc. Metatibiotarsal formula: (2) 6 / 9/ 2.
ABDOMEN. Brown, each segment with middle area and two spots along base darker.
MALE TERMINALIA ( Figs 8–9 View Fig View Fig ). Pygofer (Py – Fig. 8A, C, E–F View Fig ) short, about 2.6 × as high as long at midheight in lateral view, with posterior margin broadly rounded in lateral view; in caudal view suboval, 1.4 × as high as wide; dorsally abruptly, deeply notched. Gonostyli (G – Fig. 8B, D, G View Fig ) massive, moderately convex, subtriangular in lateral aspect with posterior margin rounded but not forming distinct lobe, anterodorsal margin distinctly convex and posterodorsal margin slightly sinuate; capitulum (ca – Fig. 8B, D, G View Fig ) elongate, rather strongly projecting dorsad and with poorly distinct neck, curved anterodorsad and more or less evenly tapering towards apex in lateral view, with basilateral laminate process directed lateroventrad in caudal view, and with distal portion anteroposteriorly laminate, apically rounded in caudal view. Anal tube (An – Fig. 8A, C, E–F View Fig ) strongly elongate, dorsoventrally flattened, and oblong, moderately narrow with lateral margins weakly sinuate in dorsal view, about 3.0 × as long as wide in dorsal view and with anal opening in basal ¼; in lateral view, downcurved and sinuate. Aedeagus (ae – Figs 8H–O View Fig , 9 View Fig ) symmetrical, rather strongly curved posterodorsad in lateral view around distal 2 /5. Ventral lobe of periandrium (vl – Figs 8J–L, N–O View Fig , 9A–E View Fig ) laminate, spatulate, with apical margin roundly notched. Dorsal lobe of periandrium (dl – Figs 8H–J, M View Fig , 9A–E View Fig ) laminate, elongate, spatulate; curved in lateral view in distal portion. Laterodorsal processes of periandrium (ldp – Figs 8H–O View Fig , 9A–E View Fig ) arising lateroventrally from middle portion of dorsal lobe, curved posterodorsad and slightly twisted, with apical hook directed dorsad and upcurved; elongate shaft (sp – Figs 8H–O View Fig , 9A–E View Fig ) directed cephalad, distinctly upcurved and reaching to about halflength of aedeagus, pointed apically. Aedeagus (sensu stricto, ae – 8H–O, 9F–H) surpassing dorsal and ventral lobes of periandrium, bifid with lateral margins sinuate, forming lateral lobe distally in dorsal aspect, and with distal portion dilated in lateral view; pair of elongate, moderately sinuate lateroventral processes (lvp – Figs 8H–M, O View Fig , 9E–G View Fig ), ribbon-like, arising at about distal third of aedeagus, somewhat spiralate, distally curved mesad above dorsal lobe of periandrium and reaching to about basal fourth of aedeagus. Connective (co – Fig. 8J View Fig ) well developed, corpus connective long, nearly straight in lateral view, tectiductus (te – Fig. 8J View Fig ) well developed, conical with anteroventral apodemes and wide anterior foramen.
Biology
