discussion
Remarks Loboscelidia barbata sp. nov. resembles L. convexa sp. nov. and L. sisik in having the following characteristics: reddish brown (L. convexa sp. nov.) to dark brown (L. sisik) body color, scale-like setae on the lower gena, and cervical expansion with longitudinal furrow (L. convexa sp. nov.). However, L. barbata sp. nov. can be distinguished by the following characteristics: rectangular frontal projection (triangular in L. sisik); strongly convex cervical expansion (weakly convex in L. sisik); cervical expansion with longitudinal furrow (L. sisik without longitudinal furrow); scape 2.9 times as long as wide (twice as long as wide in L. sisik); pronotum 0.80 times as long as posterior width (0.70 times as long as the posterior width in L. convexa sp. nov.); metanotum that 0.40 times as long as scutellum (more than 0.50 times as long as the scutellum in L. convexa sp. nov.); midtibial flange present (L. sisik absent); and longer A vein longer than Cu + M (as long as Cu + M in L. sisik).
distribution
Distribution Vietnam (Northern Vietnam, Central Vietnam) (Fig. 26).
etymology
Etymology Named after the Latin ‘ barbata ’, meaning ‘ beard’, referring to the scale-like setae on the lower gena.
