Diagnosis. Distinguished from congeners by stout dorsal and ventral barbs on profemora, well-developed bilobed ventral projection of pygophore ( Fig. 8A View FIGURE 8 ), dorsal lobes of pygophore distally swollen and convergent ( Fig. 8A View FIGURE 8 ), and eighth gonocoxa of female almost obsolete ( Fig. 10A View FIGURE 10 ).

Description. Body longer than broad ( Fig. 6A View FIGURE 6 ). Head as long as breadth across eyes. Antennal segment I reaching apex of head. Posterior margins of compound eyes convergent towards midline. Pronotum with gibbosities of callus areas distinct but low; anterolateral margins weakly denticulate; lateral angles subspinose. Scutellum with apex rounded, not dorsally reflexed. Posterior angle of laterotergites produced as small lobe.

Anterior angle of bucculae obtusely angled. Labium reaching abdominal fourth sternite (third visible); ratios 1:1.4:1.2:0.8. Peritreme 1/2 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 two ventral and one dorsal rows of spines; anteroventral row composed of three developed distal ventral spines and 2–3 proximal tubercles; posteroventral row composed of 2–3 small distal tubercles; dorsal row composed of 3–4 small distal tubercles.

Color and vestiture. Ground color straminous to testaceous with piceous punctures. Antennal segments I– II with testaceous longitudinal dorsal marking, distal 3/4 of segments III–V testaceous. Pronotum with five faint piceous longitudinal bands. Scutellum with castaneous marking on each side of anterior bulge; tongue with two faint lateral longitudinal bands Corium mottled straminous and testaceous patches. Legs mostly straminous, spines/tubercles of profemora castaneous; tibiae with two castaneous bands. Lateral portions of abdomen with castaneous band along spiracular line in males or with castaneous patches around spiracles in females.

Male. Pygophore with median narrow ventral process on ventral rim; lateral lobes of dorsal rim elongate, slightly clubbed distally, convergent before diverging distally ( Fig. 8A–C View FIGURE 8 ). Proctiger hemispherical, broadly sulcate medially; basal sclerite subquadrate, posterior margin slightly undulate ( Fig. 8C View FIGURE 8 ).

Female. Eighth gonocoxa small, almost obsolete, apically rounded. Ninth laterotergites broader than long, distally obtuse; medial margin strongly lobed, sometimes covering portions of the ninth gonocoxae ( Fig. 10A View FIGURE 10 ).

Measurements. Males (n=3): body length 15.1 SD 0.3 (14.8–15.4), anterior pronotal width 3.2 SD 0.2 (2.9–3.4), humeral width 7.4 SD 0.2 (7.1–7.6), scutellar length 5.7 SD 0.1 (5.5–5.8), medial length of sixth sternite (fifth visible) 1.2 SD <0.1 (1.2–1.2), medial length of seventh sternite (sixth visible) 2.6 SD <0.1 (2.5– 2.6). Females (n=2): body length 15.8 SD 0.2 (15.6–15.9), anterior pronotal width 3.1 SD 0.1 (3.0–3.2), humeral width 7.4 SD 0.1 (7.3–7.4), scutellar length 5.7 SD 0.2 (5.5–5.8), medial length of sixth sternite (fifth visible) 1.4 SD <0.1 (1.3–1.4), medial length of seventh sternite (sixth visible) 2.4 SD <0.1 (2.3–2.4). Appendages in Table 2.

Etymology. From the Latin word clandestinus — hidden or concealed; reflecting the cryptic coloration of the species.
