56. Cyrea marcia Canepari and Gordon , new species

Description. Male holotype. Length 2.6 mm, width 2.0 mm; body elongate oval, convex. Dorsal surface with head, pronotum and elytron smooth, shiny. Color yellow except pronotum with narrow, dark brown basomedian macula extended about 2/3 distance to anterior pronotal margin, macula with apex deeply, widely indented with yellow, lateral borders sinuate; elytron dark brown with 3 yellow spots, humeral spot small, triangular, discal spot large with irregular borders, apical spot somewhat rounded ( Fig. 310 ); ventral surface with head, prosternum yellowish brown, meso- and metaventrites dark brown; abdomen yellowish brown except median portion of ventrites slightly darker. Head punctures fine, separated by less than a diameter, each puncture 2-3 times as large as an eye facet; pronotal punctures slightly larger than head punctures, separated by less than to twice a diameter, elytral punctures larger than on pronotum, separated by 1 to 3 times a diameter; metaventral punctures smaller than on elytron medially, separated by 1 to 3 times a diameter, 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 5 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, grooved, weakly descending externally, deeply emarginate for reception of femoral apices. Protibia with narrow oblique angle, outer margin weakly arcuate, basal tooth absent, sponda slightly 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 slightly flattened medially, extended forward at apex. Ventrites 1-3 with sparse, long pubescence and coarse, dense punctures; ventrites 4-6 pubescent throughout, punctures fine, dense; 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 about 3/4 as long as paramere, slender, asymmetrical, sides mostly parallel from base to rounded apex; paramere Pvl, wide, widest medially, lower margin strongly curved from base to rounded apex ( Fig. 311, 312 ); sipho robust, strongly curved in basal 2/3, without visible alae, basal capsule with inner arm long, slender, apex feebly rounded, outer arm curved, narrowed from base to apex, wider and longer than inner arm, with accessory piece, basal border widely, shallowly emarginate ( Fig. 313, 314 ). Female. Similar to male except head dark brown, pronotum dark brown except lateral 1/7 yellowish brown, elytron with 2 pale spots, humeral spot lacking. Genitalia with spermathecal capsule short, wide, basal 1/4 slightly widened, cornu slightly enlarged with rounded apex; bursal cap oval, with 2 faintly sclerotized arms, apical strut fine, short, apical 1/3 spatulate ( Fig. 315 ).

Variation. Length 2.5 to 2.9 mm, width 2.0 to 2.3 mm. Elytron with discal spot slightly differently shaped in every specimen from highly irregular to somewhat triangular.

Type material. Holotype male; Brazil, Santarem, Acc.No. 2966. ( CMNH) . Paratypes; 2,1, same data as holotype ; 1, Brazil, Taperina, Acc.No.2966 , June ( CMNH) .

Geographical distribution. Brazil.

Remarks. Cyrea marcia may be recognized by the dorsal color pattern and lack of setal tufts on metaventrite and basal abdominal ventrite. In size and elytral color pattern it most resembles the single paratype of C. jackie , but males of C. marcia have a pale humeral spot that is lacking in males of C. jackie .
