57. Cyrea tanya Canepari and Gordon , new species

Description. Male holotype. Length 2.7 mm, width 2.0 mm; body elongate oval, convex. Dorsal surface with head weakly alutaceous, shiny, pronotum and elytron smooth, shiny. Color yellow except pronotum with long, wide, black basomedian macula extended about 5/6 distance to anterior pronotal margin, macula with apex faintly emarginate with yellow medially, lateral borders sinuate; elytron black with 2 yellow spots, humeral spot small, triangular, center of elytron with wide vitta extended from base nearly to apex ( Fig. 316 ); ventral surface with head, prosternum, meso- and metaventrites black; abdomen yellowish brown except median portions of ventrites 1-3 dark brown. Head punctures fine, separated by a diameter or less, each puncture 2-3 times as large as an eye facet; 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 a diameter; metaventral punctures larger than on elytron medially, separated by less than 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 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, 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 1/4 of prosternum, connected to base with single carina. Metaventrite with setal tuft. Basal abdominal ventrite without apparent setal tuft. Abdomen with postcoxal line on basal abdominal ventrite flattened medially, extended forward at apex. Ventrites 1-3 with dense, long pubescence and coarse, dense 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 3/4 as long as paramere, slender, asymmetrical, sides weakly convergent from base to abruptly rounded apex; paramere Pvl, wide, widest medially, lower margin strongly curved to rounded apex ( Fig. 317, 318 ); sipho robust, strongly curved in basal 1/2, without visible alae, basal capsule with inner arm short, wide, apex feebly rounded, outer arm curved, slightly wider and longer than inner arm, with accessory piece, basal border widely, shallowly emarginate ( Fig. 319, 320 ).

Female. Similar to male except head black with large, yellow macula on frons posterior to clypeus, apex of macula slightly projected medially, pronotum with basomedian macula extended to anterior pronotal margin. Genitalia with spermathecal capsule short, widened in basal 1/3, apex of cornu abruptly rounded;

bursal cap with 2 sclerotized arms, apical strut slender, slightly widened in apical 1/2, apex bent to one side ( Fig. 321 ).

Variation. None observed.

Type material. Holotype male; Bolivia, Santa Cruz, Amboro National Park , Los Volcanes.C. 1000m, S18 o 06'; W63 o 36', 20/xi-12/xii/2004, Flight Interception Trap, Mendel, H. & Barclay, M. V.I. BMNH (E)2004- 280. ( BMNH) Paratype; 1, same data as holotype except MV Light Sheet on stream beach, Barclay, M. V.I. & Mendel, H. BMNH (E)2004-280. ( BMNH)

Geographical distribution. Bolivia.

Remarks. This species is readily distinguished from all other Cyrea species except C. nellie by the bright yellow median vitta on each elytron sharply contrasted with the black background. The holotype of C. nellie is nearly identical externally, but the protibial and siphonal structures of the two species are quite different, and they are widely separated geographically. See remarks under C. nellie .
