6. Cyrea eileen Canepari and Gordon , new species

Description. Male holotype. Length 2.0 mm, width 1.6 mm; body elongate oval, convex. Dorsal surface with head weakly alutaceous, slightly shiny, pronotum and elytron smooth, shiny. Color yellow except head with black vertex; pronotum with small, black basomedian macula extended slightly more than 1/2 distance to anterior pronotal margin, macula deeply emarginate with yellow medially; elytron black with 5 yellow spots, humeral spot triangular, scutellar spot round, mediolateral spot separated from lateral margin, irregularly rectangular, discal spot obliquely oval, apical spot transversely oval, apical border of spot slightly emarginate ( Fig. 29 ); ventral surface with head, prosternum, meso- and metaventrites black; abdomen brown medially, yellowish brown toward lateral margin. Head punctures small, separated by a diameter or less, each puncture about as large as 2-3 eye facets; pronotal punctures larger than head punctures, separated by 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 a diameter or less medially, larger, denser in lateral 1/3. Clypeus slightly emarginate apically, nearly truncate, 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 curved, basal margin without trace of bordering line medially. Epipleuron narrow, grooved, not descending externally, deeply emarginate for reception of femoral apices. Protibia with oblique angle nearly as wide as remainder of protibia, outer margin sinuate, smooth, sponda not extended beyond oblique angle. Carinae on prosternal process widely separated at apex, convergent, joined at base of prosternum. Metaventrite without setal tuft. Basal abdominal ventrite without setal tuft. Abdomen with postcoxal line on basal abdominal ventrite slightly flattened medially, extended forward at apex, ventrite with sparse, long pubescence and coarse punctures medially becoming smaller and denser laterally; ventrites 2-6 pubescent throughout, punctures fine, sparse medially, becoming denser laterally; 5th ventrite slightly depressed in median 1/3, apex shallowly emarginate; 6th ventrite medially depressed, apex weakly emarginate with lateral angle rounded. Apical tergite finely, densely punctured, apex emarginate. Genitalia with basal lobe slightly more than 1/2 as long as paramere, asymmetrical, sides convergent in basal 3/4, curved to abruptly rounded apex in apical 1/4; paramere Unm, narrow at base, widened to rounded apex ( Fig. 30, 31 ); sipho strongly curved in basal 1/2, without visible alae, bursal cap with inner arm long, narrow, apex slightly rounded, outer arm longer and wider than inner arm, with accessory piece, basal border shallowly, widely emarginate ( Fig. 32, 33 ).

Female. Similar to male except head with clypeus black and base of frons with median black macula. Genitalia with spermathecal capsule elongate, slightly wider in basal 1/4, apex of cornu rounded; bursal cap rectangular, 2 outer arms sclerotized, apical strut short, widened from base to spatulate apex ( Fig. 33 ).

Variation. None observed.

Type material. Holotype male; Ecuador, Sucumbios, San Rafael Falls , 1100m, 00 o 06.24’S / 077 o 35.31’W, VIII-5/6-1998, Fred G. Andrews. ( CSCA) . Paratypes; 2, 1, same data as holotype ( CSCA) ; 1, Peru, Rio Charape , 15.Sept. 11, CHT Townsend Collector ( USNM) .

Other specimen. 1. Bolivia, Cochabamba, Carmen Pampa, 16 37’06 S 66 28’50 W, 1820m, 27.vii.2001, malaise trap, coll. A.C. Hamel L. & A. Pascall. ( BMNH).

Remarks. This is a mostly unremarkable species, but this and C. gertrude , are the only 2 very small taxa with 4 or more dark spots on each elytron within the tredecimguttata group. The mediolateral spot distinctly separated from the lateral elytral margin is somewhat unusual in the genus, and is the only external character worthy of comment. A male specimen from Bolivia is recognized as possibly this species under “other specimen.” Male genitalia appear to be identical, but the mediolateral elytral spot located on the lateral elytral border, and the somewhat disjunct geographic locality, make the identification doubtful. See remarks under C. gertrude .
