The species can be separated from all other species of Connelicita by the following features of the male terminalia: anal tube subcylindrical and elongate (~1.9 x as long as wide in dorsal view), with dorsal margin not emarginate in lateral view (Fig. 3A-C ), capitulum of gonostylus placed at apicodorsal angle and bearing two strong lateral teeth (Fig. 3A-C ), and dorsal process of periandrium forming a large lobe concave in distal portion (Fig. 3F, G ). Description. Measurements and ratios : LT: ♂ ( n = 6): 12.56 mm (11.91-13.17); ♀ ( n = 2): 13.60 (13.50-13.70). LTg/BTg = 2.19; LW/BW = 2.02; LV/BV = 1.04; LF/BF = 1.15. Head (Fig. 2A-C ): narrower than thorax and elongate, with ~2/3 of vertex length surpassing eyes and genae largely visible from above. Vertex brown, with median yellowish line, weakly concave, ~1.0 x as long in mid-line as broad basally, with lateral margins subparallel, anterior margin bisinuate, roundly produced anteriorly in middle portion, and posterior margin excavate. Frons pale yellowish brown, with two curved brown lines on disc; lateral margins finely lined in dark brown; convex in lateral view; smooth, with median carina reaching dorsal margin but not frontoclypeal suture. Genae yellowish, with brown markings between eye and anterior margin, between antennal insertion and posterior margin, and near red ocellus. Clypeus pale yellowish brown, triangular, with median carina in distal portion and with fronto-clypeal suture rounded. Labium yellowish, elongate, and narrow, reaching metacoxae, with apical segment elongate. Eyes globular (not emarginate) and protruding laterally; ocelli present. Antennae yellowish brown, with longitudinal black line along underside of pedicel; scape ring-shaped and pedicel cylindrical, longer than broad. Thorax (Fig. 2A, B ): pronotum yellowish brown, darker on middle portion, with median, yellowish carina and 3 or 4 small yellowish tubercles on sides of disc; paranotal fields with 3 black spots, one being behind eye. Mesonotum yellowish brown, with median and peridiscal carinae yellowish; blackish, slightly curved longitudinal line in lateral fields and 2 blackish points at base of scutellum. Tegulae yellowish brown. Tegmina (Figs 1A-D , 2D ): translucent, with brown spot near middle of vein CuP and vein CuA2 and apical cells weakly infuscate in middle; costal and postclaval margins slightly diverging towards the posterior; distal margin widely rounded.

Venation (Fig. 2D ): costal area well developed, with numerous cross-veins delimitating elongate cells, pterostigma absent; veins ScP+R, MP and CuA separated at base, first fork of vein ScP+R near base; first fork of vein MP after first fork of vein CuA; clavus long, reaching near 4/5 of tegmina length; veins Pcu and A1 fused at basal half of clavus. Hind wings (Fig. 2E ): translucent, with veins blackish; CuP-Pcu-A1 lobe weakly infuscate, with apical angle blackish; A2 lobe weakly infuscate and roundly protruding along postclaval margin. Venation : main veins present; ScP+R, MP, and CuA running more or less parallel, slightly diverging towards posterior; Pcu curved around distal third of wing towards CuP but not reaching the latter; A2 complete, reaching margin. Legs (Figs 1A, B , 2F ): pale yellowish brown, with dark brown marking. Metatibiotarsal formula: (2) 9 / 2 / 2. Abdomen (Fig. 1B ): Pale yellowish brown. Terminalia ♂ (Fig. 3 ): pygofer ( Py - Fig. 3A, B ) ~1.6 x as high as wide in caudal view, in lateral view with posterior margin deeply inclined posteriorly at upper 1/3 and deeply inclined forward and slightly sinuate at lower 2/3. Gonostyli ( G - Fig. 3A-C ) rather short in lateral view, with capitulum at apicodorsal angle, and with large laminate process behind capitulum; posteroventral angle rounded; capitulum ( ca - Fig. 3A-E ) laterally flattened, with posterior margin rounded in lateral view and 2 strong lateral spines derived from anterior portion, projecting lateroventrad, the dorsal one about twice as long as the ventral one. Aedeagus (Fig. 3F-I ) upcurved, with pair of lateral pointed processes ( lpa ) not reaching apex, and 3 small terminal processes, middle one with small, triangular lamina projecting anterodorsad; dorsal process of periandrium ( dpp ) large, foliaceous, somewhat shovel-shaped, and concave in distal half, and with apical margin widely rounded; paired ventral processes of periandrium ( vpp ) surpassing 1/2 length of aedeagus, elongate, and with pointed apex curved lateroposterad; connective ( co ) strongly curved. Anal tube ( An - Fig. 3 A-C ) subcylindrical, with basal ventral bulge, ~1.9 x as long as wide in dorsal view, with apical margin rounded in dorsal view, excavate in lateral view; epiproct short, located at distal third of anal tube. Female. Similar to male. Etymology. The species epithet bachmaensis refers to Bach Ma National Park where the new species was discovered. Biology. The specimens were found sitting on leaves on the lower vegetation (Fig. 4A ) in a subtropical evergreen forest (Fig. 4B ) at the junction of the Northern Vietnam lowland rain forests, Southern Vietnam lowland rain forests, and Southern Annamites montane rain forests ecoregions, at rather low altitude (150-600 m).
