Hyperaspis laterinotata Brèthes, 1925b: 6 ; Korschefsky 1931: 191; Blackwelder 1945: 447.

Description. Female holotype. Length 2.6 mm, width 2.1 mm; body oval, convex. Dorsal surface shiny with feeble alutaceous sculpture throughout. Color black; head yellow; pronotum with anterior 7/8 and anterolateral 1/4 yellow; elytron with large, yellow, triangular macula, macula projected inward from lateral margin slightly more than 1/2 distance to sutural margin ( Fig. 322 ); ventral surface with mouthparts, legs, epipleuron yellow; abdomen with median 1/3 of ventrites 1-3 dark brown, outer portion of ventrites 1-3 and remaining ventrites yellowish brown. Head punctures small, separated by less than a diameter, each puncture as large as 1 eye facet; pronotal punctures as large as on head, separated by a diameter or less; elytral punctures as large as on pronotum, separated by 1 to 2 times a diameter; metaventral punctures large, coarse, separated by less than a diameter medially, larger and denser laterally. Clypeus very slightly emarginate apically, nearly truncate, lateral angle broadly rounded. Eye canthus about 6 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, sides straight, basal and anterior angles abruptly rounded, basal margin with trace of bordering line. Epipleuron narrow, grooved, deeply emarginate for reception of femoral apices. Protibia weakly flanged, flange slightly arcuate, 1/2 as wide as remainder of protibia, outer margin smooth; sponda projecting slightly beyond flange. Carinae on prosternal process narrowly separated at apex, weakly convergent, joined at basal 1/4 of prosternum, connected to base by short stem. Metaventrite without setal tuft. Basal abdominal ventrite without median setal tuft. Primary pores laterally between ventrites 4-5 large, extended under apical 1/3 of ventrite 4, forming large, deep depression on ventrite 5; postcoxal line on basal abdominal ventrite straight in basal 1/3, extended to apical margin of ventrite at middle, curved along basal margin, rounded in apical 2/3, extended forward; Abdominal ventrites 1-4 with short, sparse pubescence, punctures on basal 3 ventrites large, separated by less than to twice a diameter, becoming smaller and dense laterally, ventrites 4-6 densely punctured throughout. Genitalia with spermathecal capsule short, curved at basal 1/3, strongly widened from base to apex; bursal cap rectangular, with 3 arms, apical strut long, “pinched” medially, apex wide, spatulate in lateral view ( Fig. 323 ).

Male. Unknown.

Variation. Unknown.

Type locality. Brazil, Rio de Janeiro.

Type depository. BMNH (holotype, examined).

Geographical distribution. Brazil.

Remarks. This species has an elytral color pattern unlike any as yet seen in Dilatitibialis . The basically black color, and large, inwardly projecting yellow macula on the lateral margin of each elytron are diagnostic for D. laterinotata .

The female holotype in the BMNH is labeled “Type (orange bordered disc)/ 60174 (handwritten)/ Brasilia Rio Jan (handwritten)/type (handwritten)/ Fry Coll. 1905.100./ Hyperaspis laterinotata Brethes (handwritten).”
