23. Cyrea arlene Gordon and Canepari , new species

Description. Male holotype. Length 2.4 mm, width 2.0 mm; body somewhat rounded, oval, convex. Dorsal surface with head weakly alutaceous, slightly shiny, pronotum and elytron smooth, shiny. Color yellow except pronotum with short, narrow, pale brown basomedian macula with short, anterior projection at each end and at middle, lateral projection feebly connected to narrow, semicircular macula on each side of middle of pronotum, semicircular macula extended slightly more than 1/2 distance to anterior pronotal margin; elytron pale yellowish brown with 6 indistinctly defined yellow spots arranged in rows of 2 each with apical spot, humeral spot triangular, scutellar spot large, oval, connected at base to elongate intermediate spot, intermediate spot between humeral and scutellar spot elongate, mediolateral spot seemingly absent, discal spot somewhat oval, apical spot transversely rectangular, anterior border of spot slightly emarginate ( Fig. 123 ); ventral surface with head, prosternum, meso- and metaventrite yellowish brown; abdomen yellow. Head punctures small, separated by less than a diameter, each puncture slightly larger than 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 less than to about a diameter; metaventral punctures larger than on elytron, separated by less than to twice a diameter medially, larger and separated by less than a diameter in lateral 1/3. Clypeus slightly emarginate apically, nearly truncate, 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 straight, basal margin without trace of bordering line medially. Epipleuron wide, grooved, slightly descending externally, deeply emarginate for reception of femoral apices. Protibia with wide oblique angle, outer margin arcuate, smooth, sponda slightly extended beyond angle. Carinae on prosternal process narrowly separated apically, convergent, joined at base of prosternum. 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 dense, short pubescence and coarse, sparse punctures; ventrites 3-6 with long, dense pubescence throughout, punctures fine, dense; 5th ventrite depressed in median 1/3, apex shallowly emarginate; 6th ventrite medially depressed, apex weakly emarginate. Apical tergite finely, densely punctured, apex emarginate. Genitalia with basal lobe about 3/5 as long as paramere, asymmetrical, sides parallel to apex, apex obliquely truncate; paramere Pav, widened from base to apex, upper margin arcuate with anterolateral impression, large, apically bifid “ear” based on emargination ( Fig. 124, 125 ); sipho strongly curved in basal 1/2, apex lost, basal capsule with inner arm somewhat elongate, wide, outer arm about as wide as and longer than inner arm, with accessory piece, basal border widely, shallowly emarginate ( Fig. 126, 127 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Colombia, Columb., Thieme , Cleothera lueteoguttata?(illegible) Chevr. ( ZMHB).

Geographical distribution Colombia.

Remarks. If the obscure elytral color pattern is consistent this species it is readily differentiated from other members of the group. The paramere of the male genitalia is unique because the anterolateral “ear” or projection is very large, and the basal lobe is apically obliquely truncate.
