Dorsal color yellow with black spots. Male abdomen with several ventrites depressed and emarginate. Penis guide of male genitalia with an apical triangular projection, penis with long slender alae.


Holotype. Male. Length 3.6 mm, width 2.0 mm; body oval, convex. Dorsal color yellow except pronotum, with a small basal black spot on each side of the disk center, a small black basal spot and a black subquadrate spot on each side at ½ from the lateral margin; scutellar shield black; each elytron with five black spots: scutellar spot slightly oval, sub-humeral spot large and oval, mid-lateral spot at the apical half of the elytron, discal and sub-apical spots rounded, the spots do not touch the elytral margin, the elytral suture or the anterior border (Fig. 59 View Figures 59–64 ). Ventral surface with head, prosternum, metaventrite and abdomen black; legs, mouthparts, and antennae yellow. Head punctures small, separated by their diameter, each puncture slightly larger than an eye facet; pronotal punctures larger than head punctures, separated by their diameter; elytral punctures as large as pronotal punctures, separated by their diameter; metaventral punctures larger than elytral punctures, separated by more than three diameters at center, about one diameter on sides. Clypeus straight. Carinae on prosternal process curved, divergent, not joined, larger than half the prosternum. Protibia not flanged, basal tooth small. Basal abdominal ventrite without setal tuft. Abdomen with postcoxal line on basal abdominal ventrite slightly flattened along posterior ventrite margin; ventrite with sparse, long pubescence and small, dense punctures. Ventrites III-VI depressed and emarginated (Fig. 60 View Figures 59–64 ). Ventrites II-VI pubescent throughout, punctures fine, dense; third ventrite with a tubercle on each side of middle. Genitalia with penis guide as long as parameres, symmetrical, sides slightly convergent, apex almost truncated but with a triangular appendage (Fig. 61 View Figures 59–64 ); parameres narrowed to apex, apex acute, setae rising from the convex side border (Fig. 62 View Figures 59–64 ); penis curved in basal ½, apex with long slender alae, basal capsule crested, inner arm of basal capsule long and slender (Figs 63 View Figures 59–64 , 64 View Figures 59–64 ).

Female. Similar to male except abdominal characters. Genitalia not examined.


Males. Length 2.9-3.1 mm, width 2.2-2.7 mm. Females. Length 2.6-3.8 mm, width 2-2.9 mm.


From the Latin inversos (= invert). The name refers to the dorsal color pattern, yellow with five black spots, the inverse of that of many Brachiacantha species (black with five yellow spots).
