83. Cyrea lucille Canepari and Gordon , new species

Description. Male holotype. Length 2.6 mm, width 2.0 mm; body elongate oval, convex. Dorsal surface with head and pronotum alutaceous, dull, elytron smooth, shiny. Color yellow except pronotum with large, black basomedian macula extended 5/6 distance to anterior pronotal border, macula with anterior margin evenly semicircular except for slight anterolateral projection; elytron black with 4 large, yellow spots, humeral spot extended posteriorly along lateral margin of elytron to apical 3/4, widened medially and at apical declivity, scutellar spot elongate posteriorly, discal spot oval, apical spot transversely oval ( Fig. 459 ); ventral surface with head, prosternum, meso- and metaventrites black; abdomen dark brown, slightly paler toward lateral margin. Head punctures small, separated by a diameter or less, each puncture as large as 2 eye facets; pronotal punctures larger than head punctures, separated by less than to twice a diameter, elytral punctures larger than on pronotum, separated by 2 to 3 times a diameter; metaventral punctures larger than on elytron, separated by less than to twice diameter. Clypeus weakly emarginate apically, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 8 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal and anterior angles abrupt, lateral margin rounded, basal margin without trace of bordering line medially. Epipleuron narrow, grooved, not descending externally, deeply emarginate for reception of femoral apices. Protibia without oblique angle, basal tooth absent, sponda slightly extended beyond protibia. Carinae on prosternal process widely separated at apex, convergent toward base, joined at basal 1/3 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, ventrite with sparse, long pubescence and small, dense punctures; ventrites 2-6 pubescent throughout, punctures fine, dense; 5th ventrite depressed in median 1/3, apex shallowly emarginate; 6th ventrite medially depressed, apex shallowly emarginate. Apical tergite finely, densely punctured, apex weakly emarginate. Genitalia with basal lobe 3/4 as long as paramere, symmetrical, sides smoothly rounded and narrowed from base to rounded apex; paramere strongly Psc, short, wide, slightly widened medially, apex rounded ( Fig. 460, 461 ); sipho robust, strongly curved in basal 2/3, with visible alae in apical 1/10, basal capsule slightly sclerotized, inner arm short, narrow, apex bifid, outer arm curved, as wide as and longer than inner arm, with accessory piece, basal border shallowly emarginate ( Fig. 462, 463 ).

Female. Similar to male except head black, pronotum with large, black median macula extended to anterior pronotal border. Genitalia with spermathecal capsule long, slender, basal 1/4 enlarged, widened, cornu apically narrowed; bursal cap narrowly rectangular, with 3 sclerotized arms, apical strut narrowed from base to spatulate apex ( Fig. 464 ).

Variation. Length 2.4 to 2.8 mm, width 1.6 to 2.1 mm. Elytron with long lateral spot sometimes broken into a humeral and median spot, creating an elytron with 5 spots, discal and apical spots are sometimes slightly connected.

Geographical distribution. Argentina.

Remarks. The dorsal color pattern is similar to several other species within this genus, and male genitalia must be examined to place C. lucille in the correct group. Within the tessulata group lucille has genitalia most similar to those of C. fasciata , C. laurie , and C. katie , but the complete, or nearly complete, black pronotal discal spot, long, yellow lateral elytral spot, and Argentina type locality seem to distinguish C. lucille . See remarks under C. katie .
