13. Cyrea trepida (Mulsant) , new combination

Cleothera trepida Mulsant, 1850: 590 .

Hyperaspis trepida: Crotch 1874: 219 ; Korschefsky 1931:198; Blackwelder 1945:448.

Description. Male. Length 2.7 mm, width 2.3 mm; body rounded, convex. Dorsal surface with head alutaceous, dull, pronotum and elytron smooth, shiny. Color yellow except pronotum with short, narrow, dark brown, sinuate basomedian macula extended about 1/8 distance to anterior pronotal margin, macula with short median projection and larger angulate projection at each end, triangular spot with emarginate posterior border present on each side of middle at midpoint of pronotum; elytron with dark brown sutural border from scutellum nearly to apex, border triangularly widened anterior to middle of elytron, 4 large, dark brown spots present, humeral spot irregularly elongate oval, narrowly connected to base of elytron anterior to humeral callus, inner margin of spot medially emarginate, discal spot broadly elongate oval, posterior lateral spot small, widely separated from lateral margin, posteromedian spot obliquely elongate oval ( Fig. 65 ); ventral surface with head, prosternum, meso- and metaventrites dark brown; abdomen yellowish brown except median 1/3 of ventrites 1-3 brown. Head punctures small, separated by less than to about a diameter, each puncture as large as an eye facet; pronotal punctures larger than head punctures, separated by less than to about a diameter, elytral punctures as large as on pronotum, separated by 1 to 2 times a diameter; metaventral punctures larger than on elytron, separated by a diameter medially, becoming denser and larger in lateral 1/2. Clypeus emarginate apically, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 4 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal and anterior angles abrupt, lateral margin nearly straight, basal margin without trace of bordering line medially. Epipleuron wide, grooved, not descending externally, deeply emarginate for reception of femoral apices. Protibia with narrow oblique angle, outer margin slightly arcuate, smooth, sponda slightly extended beyond angle. Carinae on prosternal process narrowly separated at apex, convergent, joined at basal 1/4 of prosternum, connected to prosternal base by single carina. Metaventrite without setal tuft. Basal abdominal ventrite with sparse, long setal tuft. Abdomen with postcoxal line on basal abdominal ventrite flattened along posterior ventrite margin, extended forward at apex, ventrite with sparse, long pubescence and small punctures sparse medially becoming denser laterally; ventrites 2-6 pubescent throughout, punctures fine, sparse medially, becoming denser laterally; 5th ventrite depressed in median 1/3, apex shallowly emarginate; 6th ventrite medially depressed, apex emarginate with lateral angle rounded. Apical tergite finely, densely punctured, apex weakly emarginate, nearly truncate. Genitalia with basal lobe 1/2 as long as paramere, asymmetrical, sides parallel from base to apex, apex obliquely truncate; paramere Pav, widened from base to rounded apex, upper margin with sclerotized projection, or “ear” slightly posterior to apex ( Fig. 66, 67 ); sipho strongly curved in basal 2/3, without visible alae, basal capsule with inner arm short, wide, angled forward, outer arm wider and longer than inner arm, with accessory piece, basal border shallowly, broadly emarginate ( Fig. 68, 69 ).

Female. Similar to male except head with clypeus and apex of frons faintly brown, pronotum with dark maculae wider, more pronounced than in male. Genitalia with spermathecal capsule short, slender, wide in basal 1/2, abruptly narrowed before cornu, cornu widened with apical beak; bursal cap with 2 slender outer arms, apical strut long, slender, apex slightly widened ( Fig. 70 ).

Variation. Length 2.4 to 2.8 mm, width 1.8 to 2.3 mm. Pronotum often with maculae reduced in size, sometimes with basomedian macula reduced to 3 spots, elytron may have spots in anterior 1/2 narrowly connected, and humeral spot sometimes not connected to elytral base.

Type locality. l’Amérique méridionale.

Type depository. MNHP (lectotype here designated).

Geographical distribution. Colombia, Surinam, Trinidad, Venezuela.

Specimens examined. 52. Frequently collected and widely distributed from Surinam and Trinidad south through most of Colombia. ( BMNH) ( CMNH) ( USNM) ( ZMHB).

Remarks. This species is easily identified because it has a distinctive dorsal color pattern with a pronotum strongly marked with maculae, elytron with 4 dark spots, humeral spot usually connected to elytral base and emarginate with yellow on the interior margin.

Mulsant (1850) had material only from the Dupont collection, and a female type specimen in the MNHP labeled “Type/coll. Mniszech/Trepida” is designated the lectotype. Another female type with identical labels is designated a paralectotype.
