Description. Male. Length 1.7 mm, width 1.4 mm; body oval, somewhat rounded. Dorsal surface with head alutaceous, dull, pronotum and elytron smooth, shiny. Color dark brown except head yellow, pronotum yellow with long, narrow, dark brown basomedian macula extended 3/4 distance to anterior pronotal margin, macula with apical border weakly emarginate with yellow, small, obliquely triangular yellow spot present on each side of middle; elytron with 5 large yellow spots arranged in rows of 2 each with apical spot, humeral spot triangular, mediolateral spot rectangular, projected inward, apical spot transverse with apical border deeply emarginate ( Fig. 441 ); ventral surface with antenna, mouthparts, hypomeron, and legs yellow; abdominal ventrites brownish yellow laterally, dark brown medially except ventrites 4-6 yellow. Head punctures small, separated by a diameter or less, each puncture about as large as an eye facet; pronotal punctures larger than head punctures, separated by less than to about a diameter, elytral punctures larger than on pronotum, separated by about a diameter; metaventral punctures smaller than on elytron, separated by 1 to 3 times a diameter medially, larger, separated by less than a diameter in lateral 2/3. 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, slightly 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 widely separated at apex, convergent, joined at basal 1/6 of prosternum. Metaventrite without setal tuft. Basal abdominal ventrite without 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 large 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 weakly emarginate; 6th ventrite medially depressed, apex emarginate with lateral angle rounded. Apical tergite finely, densely punctured, apex emarginate. Genitalia with basal lobe 2/3 as long as paramere, nearly symmetrical externally, weakly oval, sides slightly curved, narrowed to rounded apex in apical 1/2; paramere Psc, equal in width throughout ( Fig. 442, 443 ); sipho curved in basal 1/2, with visible alae at apical 1/6, basal capsule with inner arm short, narrow, apically emarginate, outer angle strongly projected, inner angle with apex acute, outer arm slightly wider and longer than inner arm, with accessory piece, basal border widely emarginate ( Fig. 444, 445 ).

Female. Similar to male except head brown with yellow triangular spot at base of frons, pronotum with basomedian macula extended to anterior pronotal margin. Genitalia with spermathecal capsule long, slender, basal 1/4 wide, cornu weakly enlarged at apex; bursal cap rectangular, with 3 sclerotized arms, apical strut long, widened from middle to spatulate apex ( Fig. 446 ).

Variation. Length 1.7 to 2.6 mm, width 1.4 to 1.9 mm. Pronotal and elytral color patterns vary in size of markings. Basal lobe of the male genitalia varies from slender, triangular, to wider and somewhat oval.

Type locality. “Am. mer.” (America meridionale) (South America).

Type depository. ZMUC (lectotype here designated).

Geographical distribution. Brazil, Colombia, Guyana, Surinam, Trinidad, Venezuela.

Specimens examined. 146. This is another frequently collected species known from northern and western South America ( BMNH) ( CMNH) ( DZUP) ( MIZA) ( MZSP) ( USNM) ( ZMHB).

Remarks. Cyrea fasciata is here considered to be widespread and extremely variable because neither male nor female genitalia allow discrimination into more than one species. It is probable that more than one species is involved, but molecular study will be needed to completely resolve the taxonomy.

This species is very similar to C. ormanceayi in most characteristics except body shape and form of the apical spot on each elytron. A distinctive character for recognizing those specimens of C. fasciata having elytra with dark backgrounds is the shape of the apical yellow spot on each elytron which is transverse with a strongly emarginate apical border.

A male in the ZMUC labeled “TYPE (red paper) C. fasciata , ex. Am. mer. Schmidt (handwritten)” is designated the lectotype. One other female specimen labeled “TYPE” without further labels is designated a paralectotype.
