Hyperaspis trina: Korschefsky 1931: 198 ; Blackwelder 1945: 448.

Description. Female. Length 2.7 mm, width 2.1 mm; body elongate oval, convex. Dorsal surface with head slightly alutaceous, shiny, pronotum and elytron smooth, shiny. Color yellow except head with dark brown clypeus, pronotum with long, narrow, dark brown basomedian macula extended 5/6 distance to apical pronotal margin, apex of macula entire, arcuate; elytron with 2 dark brown vitta, sutural vitta narrow, extended from posterior to scutellum nearly to apex of elytron, median vitta wider than sutural vitta, apically curved, extended from base inside humeral callus to apical 1/8 ( Fig. 644 ); ventral surface with head, prosternum, meso- and metaventrites black, trochanters dark brown; abdomen dark brown except paler brown laterally and apically. Head punctures coarse, separated by a diameter or less, each puncture about as large as 2 eye facets; pronotal punctures larger than head punctures, separated by less than to about a diameter, elytral punctures larger than on pronotum, separated by 1 to 3 times a diameter; metaventral punctures larger than on elytron, separated by less than a diameter medially, becoming larger and separated by less than a diameter toward lateral margin. Clypeus emarginate apically, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 6 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal and anterior angles abrupt, lateral margin curved, basal margin without trace of bordering line medially. Epipleuron narrow, grooved, slightly descending externally, deeply emarginate for reception of femoral apices. Protibia with narrow oblique angle, outer margin slightly arcuate, basal tooth absent, sponda slightly extended beyond protibial margin. Carinae on prosternal process widely separated at apex, convergent, joined at basal 1/5 of prosternum, connected to base with single carina. Metaventrite without setal tuft. Basal abdominal ventrite without setal tuft. Abdomen with postcoxal line on basal abdominal ventrite rounded throughout, extended forward at apex. Genitalia with spermathecal capsule short, wide, basal 1/3 slightly widened, cornu apically rounded; bursal cap rounded, with 2 sclerotized arms, apical strut short, apex abruptly widened.

Male. Unknown.

Variation. Length 2.7 to 3.0 mm, 2.1 to 2.4 mm. Pronotum with basomedian macula sometimes reduced in size to a basal dark border and obscure brown markings at middle of pronotum.

Type locality. Brazil, Rio de Janeiro.

Type depository. BMNH (holotype).

Geographical distribution. Brazil.

Specimens examined. 4. Brazil. Corcovado, Guanabara; Rio de Janeiro; S. Bocaina, 1650 m, S. J. Barreiro, SP. ( BMNH) ( DZUP) .

Remarks. Brèthes (1925b) stated that he had a single female when he described this species. The three additional specimens examined here were also females. The dorsal color pattern is diagnostic for C. trina , but placement within the genus is unknown because no males were available.
