102. Cyrea joy Canepari and Gordon , new species

Description. Male holotype. Length 2.0 mm, width 1.5 mm; body elongate oval. Dorsal surface with head, pronotum and elytron smooth, shiny. Color black except head yellow, pronotum with narrow anterior border and small, triangular, anterolateral macula yellow; elytron black except minute, triangular spot at humeral angle yellow ( Fig. 566 ); ventral surface black except mouthparts, legs yellow; abdomen dark brown. Head punctures fine, separated by a diameter or less, each puncture about as large as 2-3 eye facets; 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 diameter; metaventral punctures larger than on elytron, separated by a diameter or less medially, 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 4 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, slightly descending externally, deeply emarginate for reception of femoral apices. Protibia with narrow oblique angle, basal tooth absent, sponda distinctly extended beyond protibial margin. Carinae on prosternal process widely separated at apex, convergent toward base, joined at basal 1/6 of prosternum, connected to base by 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, ventrite with sparse, short pubescence and coarse, sparse punctures; ventrites 2-6 pubescent throughout, punctures coarse, dense; 5th ventrite slightly depressed in median 1/3, apex shallowly emarginate; 6th ventrite depressed medially, apex shallowly emarginate. Apical tergite finely, densely punctured, apex emarginate. Genitalia with basal lobe nearly as long as paramere, asymmetrical, sides curved from base to apical 2/3, curved to unevenly rounded apex in apical 1/3; paramere Psc, straight, widened from base to apex, apex rounded ( Fig. 567, 568 ); sipho robust, strongly curved in basal 2/3, without visible alae, basal capsule distinctly sclerotized, inner arm long, narrow, obliquely bifid apically, outer arm curved, wider, longer than inner arm, with accessory piece, basal border widely, shallowly emarginate ( Fig. 569, 570 ).

Female. Similar to male except head black, anterior margin of pronotum black, elytron without yellow humeral spot. Genitalia with spermathecal capsule short, rather wide, bent medially, about same width from base to rounded apex of cornu; bursal cap oval, with 2 slender, sclerotized arms, apical strut, long, slender ( Fig. 571 ).

Variation. Length 2.0 to 2.4 mm, width 1.5 to 1.7 mm. Dorsal background color varies from black to dark, pitchy brown.

Type material. Holotype male; Brazil, M. Couto N. Iguassu, Est. Rio de Janeiro, VIII-1960, M. Alvarenga leg. ( DZUP) . Paratypes; 3, 2, same data as holotype ( DZUP) ; 1, Brazil, Guarapari, E. Santo, IX-1960, M. Alvarenga leg. ( DZUP) .

Geographical distribution. Brazil.

Remarks. Cyrea joy is defined by the very small size and dark, nearly immaculate dorsal surface. It does not resemble any other known species of Cyrea , and is one of the few immediately recognizable taxa within the genus.
