Auxentius integer Horváth, 1915: 240–241 , fig. 9

Diagnosis. Recognized by well-developed flanged carina on episternal ridge; dorsal lobes of pygophore, narrow, distally turned ventrally ( Fig. 8E View FIGURE 8 ) and convergent ( Fig. 8F View FIGURE 8 ); and the absence of stout dorsal barbs on profemora.

Redescription. Body 2.2X longer than broad ( Fig. 6 View FIGURE 6 ). Head as long as breadth across eyes. Antennal segment I surpassing apex of head. Posterior margins of compound eyes straight. Pronotum with gibbosities of callus areas distinct, raised; anterolateral margins distinctly denticulate; lateral angles subspinose. Scutellum with apex angulate, dorsally reflexed. Posterior angles of laterotergites produced as distinct lobe.

Anterior angle of bucculae acute, angled ventrally. Labium reaching abdominal fourth sternite (third visible); ratios 1:1.6:1.6:1. Peritreme 2/5 as long as distance from ostiole of metathoracic scent gland to lateral margin of metapleuron. Episternal ridge located 4/5 of distance between ostiole of metathoracic scent gland and lateral margin of metapleuron. Profemora armed with anteroventral row of 3–4 small distal tubercles.

Color and vestiture. Ground color straminous with piceous punctures. Antennal segment I with piceous longitudinal dorsal marking; distal 3/4 of segments II–V piceous. Posterior margin of pronotum with five faint piceous triangular spots along posterior margin. Scutellum with castaneous marking on each side of anterior bulge; tongue with two faint lateral longitudinal bands. Corium of mottled straminous and rubignaceous patches. Legs mostly straminous with piceous speckling, tibiae with two castaneous bands. Lateral portions of abdomen with interrupted irregular castaneous band along spiracular line or with castaneous patches around spiracles.

Male. Pygophore with ventral rim produced posteriorly, ventrally concealing median ventral process; process low, deeply emarginate medially; lateral lobes of dorsal rim long, not swollen distally, tip curved venterolaterally ( Fig. 8D–F View FIGURE 8 ). Proctiger hemispherical, sulcate medially; basal sclerite with posterior margin slightly broader than anterior margin ( Fig. 8F View FIGURE 8 ).

Female. Eighth gonocoxa small, apically rounded, located in a shallow emargination of seventh sternite (sixth visible). Ninth laterotergites longer than broad, hatchet–shaped ( Fig. 10B View FIGURE 10 ).

Measurements. Males (n=5): body length 16.1 SD 0.6 (15.4–17.1), anterior pronotal width 3.2 SD 0.1 (3.0–3.4), humeral width 7.9 SD 0.3 (7.4–8.4), scutellar length 5.9 SD 0.1 (5.8–6.1), medial length of sixth sternite (fifth visible) 1.3 SD 0.1 (1.1–1.4), medial length of seventh sternite (sixth visible) 2.5 SD 0.1 (2.3– 2.8). Females (n=5): body length 17.2 SD 0.3 (16.9–17.7), anterior pronotal width 3.4 SD <0.1 (3.4–3.5), humeral width 8.2 SD 0.2 (7.9–8.6), scutellar length 6.2 SD 0.1 (6.0–6.3), medial length of sixth sternite (fifth visible) 1.4 SD 0.1 (1.3–1.5), medial length of seventh sternite (sixth visible) 2.4 SD 0.1 (2.2–2.6).
