Hyperaspis suzannae Crotch, 1874: 219 ; Korschefsky 1931: 197; Blackwelder 1945: 448; Gordon 1987: 27.

Hyperaspis pulcherrima Mader, 1954: 127 . (NEW SYNONYM).

Description. Male. Length 2.6 mm, width 2.2 mm; body rounded, slightly elongate, convex. Dorsal surface shiny, lacking alutaceous sculpture except head and pronotum slightly alutaceous. Color yellow except pronotum with narrow, basomedian, dark brown band widened at each end, 1 triangular, light brown spot medially on each side of middle; elytron narrowly bordered with light brown, sutural border slightly widened on disc, 2 large black spots present medially, anterior spot irregularly transversely rectangular with apical border weakly emarginate, posterior spot on apical declivity irregularly transversely oval with posterior border weakly emarginate ( Fig. 67 ); ventral surface with head, prosternum, meso- and metaventrites reddish brown; abdomen reddish brown. Head punctures small, separated by about a diameter, each puncture as large as an eye facet; pronotal punctures slightly larger than head punctures, separated by less than to twice a diameter; elytral punctures larger than those on pronotum, separated by 1-3 times a diameter; metaventral punctures slightly larger than on abdomen medially, larger and separated by less than a diameter toward lateral margin. Clypeus deeply 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 slightly rounded, basal margin without trace of bordering line. Epipleuron narrow, grooved, slightly descending externally, deeply emarginate for reception of femoral apices. Protibia strongly flanged, flange wider than remainder of protibia, outer margin rounded, smooth, sponda extended slightly beyond protibial flange ( Fig. 68 ). Carinae on prosternal process widely separated at apex, weakly convergent toward base, joined at basal 1/6 with single carina extended to basal margin of prosternum. Metaventrite without setal tuft. Basal abdominal ventrite without setal tuft. Abdomen with primary pores laterally between ventrites 4-5 large, extended under apical 1/2 of 4th ventrite; postcoxal line on basal abdominal ventrite rounded, flattened along posterior ventrite margin, weakly extended forward, ventrite with sparse, long pubescence and small, sparse punctures; ventrites 2-4 pubescent throughout, punctures small, dense, becoming denser toward lateral margin; 5th ventrite slightly depressed medially in apical 1/2, depressed by primary pore laterally, without tubercle on each side of middle, apical margin broadly emarginate, surface weakly punctate; 6th ventrite short, narrow, depressed medially, apical margin broadly emarginate, sparsely pubescent on each side of median depression, lateral angle abruptly rounded, surface feebly punctured. Apical tergite coarsely, densely punctured, pubescent, apex weakly rounded. Genitalia with basal lobe slightly shorter than paramere, asymmetrical, slightly narrowed from base to weakly triangular apex; paramere weakly Psc, apex with small, ventral projection, dorsal surface broadly, strongly rounded ( Fig. 69, 70 ); sipho robust, strongly curved in basal 1/2, basal capsule large, inner arm slender, slightly sinuate, apex narrowly rounded, outer arm wider and slightly longer than inner arm, with accessory piece, basal border broadly emarginate ( Fig. 71, 72 ).

Female. Similar to male except clypeus brown. Genitalia with spermathecal capsule short, wide, widened from base to apex, cornu widened at apex; bursal cap narrowly oval, with 3 arms, inner arm short, faint, apical strut long, apex flattened in lateral view ( Fig. 73 ).

Variation. Length 1.6 to 3.0 mm, width 1.5 to 2.3 mm.

Type locality. Of suzannae , ( Venezuela), Cumana ; of pulcherrima , Venezuela.

Type depository. Of suzannae, UMZC (lectotype designated by Gordon 1987); of pulcherrima, (NHMV) (holotype, examined).

Geographical distribution. Trinidad, Venezuela.

Specimens examined. 9. Tobago. Plymouth Rd . Trinidad. “ Trinidad. ” Venezuela. Aragua, Rancho Grande, 1100m .; Caracas Valley ; Cerama (?), Edo., Carabobo ; Estado Aragua, P. Nac. Henri Pittier, Maracay / Occumare km 36, La Trilla, 300m. ; Prov. Cumana , Sucre ; Estado Aragua, P. Nac. Henri Pittier, Campo Experimental CENIAP, Pozo del Diablo , 400m. ; San Esteban, nr. Puerto Cabello. ( BMNH) ( NHMV) ( UMZC) ( USNM) .

Remarks. Dilatitibialis suzannae has a unique dorsal color pattern by which it may be recognized within the genus.

Type material of Hyperaspis pulcherrima (NHMV) was examined and found to be conspecific with the lectotype of D. suzannae . In addition to the holotype of D. pulcherrima , there are 2 paratypes in the NHMV collection bearing identical labels. Mader’s male holotype is labeled “D’Moritz 1858 Venezuela / Holotype Hyperaspis pulcherrima m (pink paper, handwritten)/ Coll. Muls. Vindob.”
