Hinda joeli Almeida and Milléo, 2000: 84 .

Description. Female. Length 2.6 mm, width 1.9 mm; body slightly elongate, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; head brown except clypeus and area above antennal insertion brownish yellow; pronotum black except lateral 1/3 yellow; elytron brown with 2 yellow spots, elongate oval spot on disc, and transversely oval spot at apex ( Fig. 359 ); venter of head, prosternum, mesoventrite reddish yellow, metaventrite reddish brown; abdomen with ventrites 1–3 yellowish brown, ventrites 4–6 yellow. Head punctures small, separated by diameter or less, each puncture as large as 2 eye facets; pronotal punctures smaller than head punctures, separated by diameter or less; elytral punctures equal in size to pronotal punctures, separated by less than 2 times diameter. Clypeus weakly emarginate apically, nearly truncate, lateral angle abruptly rounded. Eye canthus about 5 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal angle broadly rounded, anterior angle abruptly rounded, lateral margin rounded, basal margin with trace of bordering line. Epipleuron narrow, weakly grooved, deeply emarginate for reception of femoral apices. Protibial flange narrower than remainder of protibia, outer margin arcuate with about 8 small teeth medially and on basal 1/2, sponda slightly extended beyond protibial border. Carinae on prosternal process widely separated at apex, convergent, joined at prosternal base. Abdomen without primary pores laterally between ventrites 4–5; postcoxal line on basal abdominal ventrite straight in basal 1/3, curved along apical margin of ventrite, apex extended forward. Abdominal ventrites with long, sparse pubescence, punctures on ventrites 1–3 large, separated by about diameter medially, becoming smaller and dense laterally, ventrites 3–6 densely punctured throughout. Genitalia with spermatheca short, stout, curved medially, cornu enlarged; bursal cap oval, with distinct arms, apical strut elongate, apical 1/2 curved, spatulate in lateral view ( Fig. 362 ).

Male. Similar to female except head yellow, pronotum with median black area apically emarginate, not reaching anterior pronotal margin. Genitalia (after Almeida and Milléo 2000) with basal lobe slightly shorter than paramere, sides convergent, apex obliquely truncate; paramere Unm type, widened apically, apex rounded ( Fig. 360 ); sipho robust, wide, curved in basal 2/3, basal capsule large, inner arm short, wide, apex obliquely truncate, outer arm wide, as long as inner arm, with accessory piece, basal border deeply emarginate ( Fig. 361 ).

Variation. Length 2.7–2.8 mm, width 2.0– 2.2 mm.
