: Maxillary palpus four-segmented; labial palpus with second segment ca. 1.5x longer than basal segment. Mandible with outer and condylar ridges converging apically; with two teeth, upper tooth very slightly shorter and wider than lower tooth; inner margins of upper and lower teeth forming nearly 80 degree angle; upper tooth with inner and dorsal margins forming ca. 45 degree angle; inner, ventral margin of mandible carinate apically, weakly diverging away from condylar ridge. Clypeus with distinct truncation medially on apical margin, lateral corner of truncation forming ca. 140 degree angle with lateral margin of clypeus. Inner margin of antennal socket weakly carinate, raised dorsomedially and slightly overhanging socket. Interantennal area and frons clearly elevated above level of paraocular area. Flagellar segments subequal in length, except F1 half F2 length, F11 nearly one-fourth longer than other segments. Vertex behind lateral ocellus ca. 2.0 OD in length. Genal width three fourths compound eye width in lateral view or slightly more. Preoccipital margin rounded, not carinate. Hypostomal carina moderately high, very slightly higher midway along length of proboscidial fossa, shorter at angle, not forming distinct tooth. Pronotal lobe and omaulus with strong carinae separating anterior and lateral surfaces. Scutellum with triangular medial and lateral notches in the anterior margin, forming three pockets (one median and two lateral) at the suture between the mesoscutum and mesoscutellum. Malus forming triangular apical spine about same size as adjacent margin of velum, inner margin of spine with minute hairs. Foretarsal segments 2–3 with anterior lobes distinctly longer than posterior. Mid and hindtarsi not swollen. Hindtibial spurs moderately curved at apical sixth, outer spur slightly shorter than inner. Hind basitarsus relatively long, slender, with lateral margins of outer surface parallel, lacking tooth on inner margin. T6 medioapical margin with small impunctate truncation, this truncation very weakly concave along width. T6 lateroapically with triangular tooth (apex rounded); lateroapical margin of T7 somewhat recessed, not continuous with apical margin of medioapical impunctate truncation. T6 lateroapical tooth larger than T7 submedian tooth. T7 midapically with shallow emargination, forming ca. onefourth of circle in outline, with teeth on either side of emargination very small, triangular). S2 widely, weakly subtruncate, medially nearly straight; disc of S2 overhanging much of S

S4 apical margin laterally with carinae forming posteriorly directed trough, medially ventral-most carina reduced to obsolescence where punctures overlay medioapical margin. S5 apical margin only partially visible, but apparently shallowly, widely emarginate. S6 apical margin strongly convex, not forming distinct truncation. S8 apical margin triangular. Gonoforceps strongly swollen subapically, with distinct secondary projection arising from inner apical margin (more distinctly visible in lateral view); this secondary projection apically swollen; gonoforceps more or less straight along length in lateral view.
