99. Cyrea allison Canepari and Gordon , new species

Description. Male holotype. Length 3.3 mm, width 2.4 mm; body elongate oval, convex. Dorsal surface with head alutaceous, dull, pronotum and elytron smooth, shiny. Color yellow except head black with clypeus and anterolateral angle of frons yellow, pronotum with long, narrow basomedian macula extended 3/4 distance to anterior pronotal margin, macula with apex medially indented with yellow, lateral borders sinuate; elytron black with narrow yellow vitta on lateral margin from humeral angle to apical declivity, and small, somewhat transversely oval reddish yellow spot at apex ( Fig. 549 ); ventral surface with head, prosternum, meso- and metaventrites black; abdomen yellowish brown except median portions of ventrites 1-4 brown. Head punctures fine, separated by less than a diameter, each puncture about 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 twice a diameter; 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, nearly truncate, 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, grooved, not descending externally, deeply emarginate for reception of femoral apices. Protibia with narrow oblique angle, basal tooth absent, sponda slightly extended beyond protibial margin. Carinae on prosternal process widely separated at apex, parallel to middle of prosternum, apparently not joined apically. Metaventrite without setal tuft. Basal abdominal ventrite without setal tuft. Abdomen with postcoxal line on basal abdominal ventrite flattened medially, extended forward at apex. Ventrites 1-3 with sparse, short pubescence and coarse, sparse punctures; ventrites 4-6 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 emarginate. Genitalia with basal lobe about 2/3 as long as paramere, slender, asymmetrical, sides weakly convergent from base to apical 1/4, curved to rounded apex in apical 1/4; paramere Psc, slender throughout, apex rounded ( Fig. 550, 551 ); sipho robust, strongly curved in basal 1/2, without visible alae, basal capsule with inner arm short, wide, apex weakly bifid, outer arm wider, longer than inner arm, narrowed from base to apex, with accessory piece, basal border shallowly emarginate ( Fig. 552, 553 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Ecuador, Canar Prov., 22 km SE El Triunfo , 200m, 2.III.81, H. Howden. ( USNM).

Geographical distribution. Ecuador.

Remarks. This large species has a dorsal color pattern differing from that of any known species of Cyrea , and males have a mostly black head, making identification relatively simple.
