109. Cyrea courtney Canepari and Gordon , new species

Description. Male holotype. Length 3.9 mm, width 2.6 mm; body elongate, nearly parallel sided, convex. Dorsal surface with head, pronotum alutaceous, dull, elytron smooth, shiny. Color yellow except pronotum with large, black macula extended 2/3 distance to apical pronotal margin, apex of macula entire, slightly arcuate; elytron black except basal, lateral, and apical margins broadly yellow, median yellow vitta reduced to elongate oval spot ( Fig. 608 ); ventral surface with head, prosternum, meso- and metaventrites black; abdomen dark brown except ventrites 5-6 reddish yellow. Head punctures fine, separated by a diameter or less, each puncture as large as an eye facet; pronotal punctures larger than head punctures, separated by less than to twice a diameter, elytral punctures larger than on pronotum, separated by less than to about a diameter; metaventral punctures larger than on elytron medially, separated by a diameter or less, becoming larger and separated by less than a diameter toward lateral margin. 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, grooved, slightly descending externally, deeply emarginate for reception of femoral apices. Protibia with wide oblique angle, almost flanged, outer margin arcuate, basal tooth absent, sponda widely extended beyond protibial margin. Carinae on prosternal process widely separated at apex, convergent, joined at basal 1/3 of prosternum, connected to base with single carina. 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 1-3 with dense, short pubescence and coarse, sparse punctures; ventrites 4-6 with dense, fine punctures; 5th ventrite slightly depressed in median 1/3, apex shallowly emarginate; 6th ventrite medially depressed, apex shallowly emarginate. Apical tergite finely, densely punctured, apex emarginate. Genitalia with basal lobe 3/4 as long as paramere, wide, asymmetrical, sides parallel from base to rounded apex; paramere Psc, long, wide, slightly widened medially, apex rounded ( Fig. 609, 610 ); sipho robust, strongly curved in basal 1/2, with visible alae in apical 1/6, basal capsule with inner arm short, slender, apex obliquely bifid, outer arm curved, wider and longer than inner arm, with accessory piece, basal border abruptly emarginate ( Fig. 611, 612 ).

Female. Similar to male except head black. Genitalia with spermathecal capsule long, slender, basal 1/5 widened, apex of cornu acute; bursal cap rectangular with 3 heavily sclerotized arms, apical strut long, apex abruptly widened ( Fig. 613 ).

Variation. Length 3.7 to 3.9 mm, width 2.5 to 2.6 mm. Elytron with elongate median vitta enlarged, extended to basal and apical yellow borders, or vitta more widely expanded and more widely connected to yellow borders.

Type material. Holotype male; ( Brazil) Vila Monte Verde, Minas Gerais, 9.II.1965, Halik 26507. ( USNM) . Paratypes; 7, 1 ( Brazil) V. Monte Verde, M. Gerais, 25.II.1964, Halik 23968 ( USNM) ; 1, Brazil, Minas Gerais, Poco de Caldas , ZII 1965, Coll. O. Leoncini ( CAS) ; 5, Brazil, SC, Nova Teutonia , I.1966, F. Plaumann col. ( DZUP) .

Geographical distribution. Brazil.

Remarks. Cyrea courtney has a vittate elytral color pattern that is different from other vittate species of Cyrea . However, it is somewhat variable as the paratypes from Nova Teutonia have the yellow elytral vittae and borders more widely expanded and more broadly connected, leaving a central dark vitta on each elytron.
