94. Cyrea rosemary Canepari and Gordon , new species

Description. Male holotype. Length 3.0 mm, width 2.5 mm; body elongate oval, convex. Dorsal surface with head alutaceous, dull, pronotum and elytron smooth, shiny. Color yellow except head with narrowly black vertex, pronotum with large, black basomedian macula occupying all of surface except narrow anterior and lateral borders yellow; elytron dark brown with 5 small yellow spots, humeral spot oval, median lateral spot projected inward, discal spot irregularly oval, apical spot transversely oval ( Fig. 519 ); ventral surface with head, prosternum, meso- and metaventrites dark brown; abdomen brown. Head punctures coarse, separated by less than a diameter, each puncture about as large as 3 eye facets; pronotal punctures as large as head punctures, separated by less than to 3 times a diameter, elytral punctures larger than on pronotum, separated by a diameter or less; metaventral punctures as large as on elytron medially, separated by a diameter or less, becoming larger and separated by less than a diameter toward lateral margin. Clypeus weakly 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 weakly curved, basal margin without trace of bordering line medially. Epipleuron narrow, feebly grooved, not descending externally, deeply emarginate for reception of femoral apices. Protibia with weak oblique angle, basal tooth absent, sponda slightly extended beyond protibial margin. Carinae on prosternal process widely separated at apex, convergent toward base, joined almost at base of prosternum. Metaventrite without setal tuft. Basal abdominal ventrite without setal tuft. Abdomen with postcoxal line on basal abdominal ventrite rounded throughout, slightly extended forward at apex, ventrite with sparse, short pubescence and fine, sparse punctures; ventrites 2-6 pubescent throughout, punctures fine, dense; 5th ventrite not depressed in median 1/3, apex shallowly emarginate; 6th ventrite not medially depressed, apex shallowly emarginate. Apical tergite finely, densely punctured, apex emarginate. Genitalia with basal lobe longer than paramere, slender, asymmetrical, sides convergent from base to apical 1/8, rounded to truncate apex in apical 1/8; paramere Psc, wide throughout, apex rounded ( Fig. 520, 521 ); sipho robust, strongly curved in basal 1/2, narrowed at apical 1/8, without visible alae, basal capsule weakly sclerotized, inner arm short, narrow, weakly bifid apically, outer arm wider, longer than inner arm, with accessory piece, basal border shallowly emarginate ( Fig. 522, 523 ).

Female. Similar to male except head entirely dark brown, pronotum dark brown except lateral border narrowly yellow. Genitalia with spermathecal capsule elongate, basal 1/5 widened, cornu apically narrowed; bursal cap narrowly rectangular, with 3 sclerotized arms, apical strut short, weakly curved, slender ( Fig. 524 ).

Variation. Length 2.8 to 3.2 mm, width 2.2 to 2.6 mm.

Type material. Holotype male; Paraguay, Sapucay, Mar., WT Foster Collector. ( USNM) . Paratypes; 4, same data as holotype except additional month “Feb.” ( USNM) .

Geographical distribution. Paraguay.

Remarks. Cyrea rosemary is not easily distinguished from some other tessulata group species, but neither can it be placed with any one of them. The small, yellow elytral spots and basal lobe of male genitalia longer than paramere are a combination not found elsewhere.
