26. Cyrea crotchi (Harold) , new combination

Hyperapis crotchi Harold, 1875: 213 ; Korschefsky1931: 186 (replacement name for Hyperaspis carolinae Crotch, 1874: 223 ).

Hyperaspis carolinae Crotch,1874: 223 ; Korschefsky 1931: 186; Gordon 1987: 28 (preoccupied by

Hyperaspis carolinae Crotch, 1874: 220 , now Dilatitibialis carolinae ).

Description. Male. Length 3.3 mm, width 2.7 mm; body elongate oval, convex. Dorsal surface with head alutaceous, dull, pronotum and elytron smooth, shiny. Color yellow except pronotum with black, basomedian macula extended 3/4 distance to apical pronotal margin, apex of macula widely projected, weakly emarginate with yellow medially; elytron black with 2 yellow spots, humeral spot small, triangular, spot on lateral apical declivity elongate oval ( Fig. 140 ); ventral surface with head, prosternum, meso- and metaventrites black, metafemur brown; abdomen dark brown except ventrite 6 yellowish brown. Head punctures small, separated by a diameter or less, each puncture as large as 2-3 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 2 times a diameter; metaventral punctures larger than on elytron, separated by less than a diameter medially, larger, nearly contiguous in lateral 1/2. Clypeus slightly emarginate apically, nearly truncate, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 6 eye facets long, angled forward, wide, rounded throughout, pale yellow. Pronotum narrowed from base to apex, basal and anterior angles abrupt, lateral margin slightly curved, basal margin without trace of bordering line medially. Epipleuron wide, weakly grooved, slightly descending externally, deeply emarginate for reception of femoral apices. Protibia with narrow oblique angle, outer margin arcuate, smooth, sponda extended beyond angle ( Fig. 141 ). Carinae on prosternal process narrowly separated at apex, convergent, joined at basal 1/4 of prosternum, connected to base by 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, ventrites 1-2 with sparse, long pubescence and coarse punctures; ventrites 3-6 pubescent throughout, punctures fine; 5th ventrite depressed in median 1/3, apex widely, shallowly emarginate; 6th ventrite deeply depressed medially, apex widely, deeply emarginate with lateral angle rounded. Apical tergite finely, densely punctured, apex weakly emarginate. Genitalia with basal lobe slender, slightly more than 1/2 as long as paramere, sides slightly convergent from base to obliquely truncate apex, paramere Pav, widened from base to rounded apex, upper anterior angle with almost membranous projection terminated with apically forked “ear” ( Fig. 142, 143 ); sipho strongly curved in basal 2/3, without visible alae, basal capsule with inner arm short, wide, apex rounded, outer arm slightly wider and longer than inner arm, with accessory piece, basal border widely, abruptly emarginate ( Fig. 144, 145 ).

Female. Similar to male except head black, pronotum black except narrow anterolateral angle yellow, elytron with humeral spot absent. Genitalia with spermathecal capsule slightly elongate, slender, narrowed at middle, apex of cornu rounded; bursal cap rounded, with 2 feebly sclerotized arms, apical strut short, slender, apex abruptly widened ( Fig. 146 ).

Variation. Length 3.4 to 3.8 mm, width 2.7 to 3.2 mm. Size and shape of apical spot on elytron somewhat variable.

Type locality. Not stated, but almost certainly Brazil.

Type depository. UMZC (lectotype designated by Gordon, 1987).

Geographical distribution. Brazil.

Specimens examined. 6. Brazil. Corupa, (Hansa Humboldt), S. Cath.; Nova Teutonia; Rio de Janeiro. ( BMNH) ( CAS) ( CMNH) ( DZUP) ( ZMHB).

Remarks. The dorsal color pattern of C. crotchi is distinctive on its own, but the species is positively identified by the wide, rounded (fat), pale yellow eye canthus. The shape of the canthus is similar only to that of C. flavocalceata .

Crotch (1874) described Hyperaspis carolinae on page 220, then repeated the same name on page 223. Harold (1875) replaced the latter name with H. crotchi . Hyperaspis carolinae Crotch (1874, p. 220) was transferred to Dilatitibialis by Canepari and Gordon (2013).
