33. Cyrea agnes Canepari and Gordon , new species

Description. Male. Length 3.4 mm, width 2.8 mm; body elongate oval, convex. Dorsal surface with head weakly alutaceous, slightly shiny, pronotum and elytron smooth, shiny. Color yellow except pronotum with black basomedian macula extended slightly more than 2/3 distance to anterior pronotal margin, macula protruding medially, anterior border widely, deeply emarginate with yellow medially; elytron black with 5 large, yellow spots arranged in rows of 2 each plus apical spot, humeral spot irregularly rectangular, scutellar spot round, mediolateral spot projected inward, discal spot irregularly oval, apical spot transversely rectangular with apical border weakly emarginate ( Fig. 182 ); ventral surface with head, prosternum, meso- and metaventrite black; abdomen yellow except median portion of ventrites1-3 brown. Head punctures small, separated by less than a diameter, each puncture about as large as 2 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 twice a diameter; metaventral punctures larger than on elytron, separated by a diameter or less medially, larger and separated by less than a diameter in lateral 1/3. Clypeus slightly 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 slightly curved, basal margin without trace of bordering line medially. Epipleuron wide, slightly grooved, weakly descending externally, deeply emarginate for reception of femoral apices. Protibia with wide oblique angle, outer margin slightly arcuate, smooth, sponda slightly extended beyond angle. Carinae on prosternal process widely separated at apex, convergent toward base, carinae joined just before basal prosternal margin. Metaventrite with dense setal tuft. Basal abdominal ventrite with dense setal tuft. Abdomen with postcoxal line on basal abdominal ventrite rounded throughout, extended forward at apex, ventrites 1-2 with coarse, dense punctures; ventrites 3-5 with long, dense pubescence throughout, punctures fine, dense; 5th ventrite depressed in median 1/3, surface with long, dense setae, apex shallowly emarginate; 6th ventrite medially depressed, apex weakly emarginate. Apical tergite finely, densely punctured, apex emarginate. Genitalia with basal lobe shorter than paramere, asymmetrical, sides weakly convergent from base to rounded apex; paramere Pem, sinuate, widened from narrow base to wide apex, lower margin curved, upper margin sinuate, apex obliquely truncate ( Fig. 183, 184 ); sipho strongly curved in basal 1/2, without visible alae, basal capsule with inner arm long, wide, outer arm narrower and slightly longer than inner arm, with accessory piece, basal border broadly, shallowly emarginate ( Fig. 185, 186 ).

Female. Similar to male except head black with frons medially and basally yellow, pronotum entirely black except anterolateral angle triangularly yellow. Genitalia with spermathecal capsule short, weakly curved, slightly widened from base to rounded apex; bursal cap oval with 2 slender, sclerotized arms, apical strut short, slender, apical 1/3 spatulate ( Fig. 187 ).

Variation. Length 3.3 to 3.6 mm, width 2.4 to 2.0 mm. Female head varies from that described above to entirely black with median, yellow triangular macula on frons, female pronotum may have a central, diamond shaped macula, and elytron rarely with apical and discal spots narrowly connected.

Type material. Holotype male; Peru, Callanga, ex. Coll. J. Weise ( ZMHB) . Paratypes; 12, 10, same data as holotype ( ZMHB) ; 1, ( Peru) Tingo Maria, 21.8.64, J. Lamas Coll., S.N.A., 784-64 ( JEBC) ; 1, Peru, Satipo, x-xii.1935., F. Waytkowski (sic), B.M.1936-732 ( BMNH) .

Geographical distribution. Peru.

Remarks. Cyrea agnes is not easily recognized by external appearance alone except that it is larger than most of the similarly patterned species. It is distinctive by males having dense setal tufts on the metaventrite and basal abdominal ventrites. Male genitalia are also extremely distinctive and diagnostic.
