Diagnosis. Distinguished by relatively long labium, sparsely punctate pronotum, wedge–shaped proctiger in males, and pygophore with outer ventral rim surpassing posterior of dorsal margin ( Fig. 19K View FIGURE 19 ).
Description. Body 2X longer than broad ( Fig. 16H View FIGURE 16 ). Vertex of head slightly convex, punctate. Juga apically acute, rounded laterally. Juga and tylus subequal in length. First antennal segment subequal with apex of head. Eyes stalked; posterior margins converging with head at right angle. Pronotum rugose; anterolateral margins crenulate; lateral angles acute. Scutellum swollen anteriorly; apex broadly rounded, somewhat angulate, dorsally reflexed. Laterotergites with posterior angles weakly produced into small rounded tubercles.
Bucculae produced, becoming obsolete prior to reaching posterior margin of head; anterior angle of bucculae acute, directed anteroventrally. Labium reaching seventh abdominal sternite (sixth visible); ratios 1:1.75:1.8:1. Peritreme 2/5 as long as distance from ostiole of metathoracic scent gland to lateral margin of metapleuron. Episternal ridge located 2/3 of distance between ostiole of metathoracic scent gland and lateral margin of metapleuron. Venter of abdomen primarily convex; median distinctly sulcate. Profemora with 7–8 ventral thorn–shaped spines; spines becoming larger on distally portions.
Color and vestiture. Ground color straminous to testaceous with black shining punctures. Antennal segments I–III testaceous with piceous markings; segments IV–V piceous. Legs mostly straminous; tibiae with two castaneous bands on longitudinal ridges. Abdomen mostly straminous, spiracles surrounded by black spot. Antennal segments I–II and proximal portion of segment III shiny with sparse vestiture; remainder of segment III and segments IV–V with dense short pile.
Male. Ventral rim of pygophore thickly produced posteriorly, shallowly emarginated medially ( Fig. 19J– L View FIGURE 19 ). Proctiger elongate, wedge–shaped; basal sclerite shallowly trilobed posteriorly, anterior margin straight ( Fig. 19L View FIGURE 19 ).
Female. Eighth gonocoxa triangular, extremely concave medially. Ninth laterotergites swollen almost cylindrical in cross section, narrowed throughout ( Fig. 20F View FIGURE 20 ).
Measurements. Males (n=1): body length 18.3, anterior pronotal width 3.3, humeral width 9.6, scutellar length 6.7, medial length of sixth sternite (fifth visible) 1.1, medial length of seventh sternite (sixth visible) 2.6. Females (n=2): body length 19.7 SD 0.2 (19.6–19.9), anterior pronotal width 3.5 SD 0.1 (3.4–3.6), humeral width 9.4 SD 0.1 (9.3–9.5), scutellar length 7.6 SD 0.3 (7.3–7.8), medial length of sixth sternite (fifth visible) 0.8 SD 0.0 (0.8–0.8), medial length of seventh sternite (sixth visible) 1.2 SD 0.1 (1.2–1.3).
