101. Cyrea exclamationis (Mulsant) , new combination

Hyperaspis exclamationis Mulsant, 1850:654 ; Weise 1906:229; Korschefsky 1931:188; Blackwelder 1945:447.

Description. Male. Length 2.6 mm, width 1.8 mm; body elongate oval, convex. Dorsal surface with head weakly alutaceous, slightly shiny, pronotum alutaceous, dull, elytron smooth, shiny. Color yellow with pronotum all black except narrow anterior and lateral borders yellow; elytron black with lateral vitta and 2 spots yellow, lateral vitta extended from humeral angle nearly to suture at apex, scutellar spot small, somewhat triangular, discal spot elongate, obliquely oval ( Fig. 560 ); ventral surface with head, prosternum, meso- and metaventrites black; abdomen mostly dark brown except paler brown laterally and apically. Head punctures fine, separated by less than a diameter, each puncture about as large as an eye facet; pronotal punctures about as fine as head punctures, separated by less than to 3 times a diameter, elytral punctures larger than on pronotum, separated by 1 to 3 times a diameter; metaventral punctures larger than on elytron, separated by less than to twice diameter 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 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, arcuate, basal tooth absent, sponda slightly extended beyond protibial margin. Carinae on prosternal process widely separated at apex, parallel to basal 1/4 of prosternum, joined at basal 1/4, connected to prosternal 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. Ventrites 1-6 with sparse, short pubescence and fine, sparse punctures; 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 slightly shorter than paramere, slender, slightly asymmetrical, sides parallel from base to apical 1/ 3, curved to rounded apex in apical 1/3; paramere Psc, wide, apex rounded ( Fig. 561. 562 ); sipho robust, strongly curved in basal 2/3, with visible alae at apical 1/6, basal capsule with inner arm long slender, narrowed medially, apex bifid, outer arm wider, longer than inner arm, curved, with accessory piece, basal border shallowly emarginate ( Fig. 563. 564 ).

Female. Similar to male except head black, pronotum with anterior border black. Genitalia with spermathecal capsule long, slender, basal 1/6 widened, apex of cornu acute; bursal cap rectangular, with 3 heavily sclerotized arms, apical strut robust, short, extreme apex slightly widened ( Fig. 565 ).

Variation. Length 1.9 to 2.7 mm, width 1.5 to 2.0 mm.

Type locality. Brazil.

Type depository. MHNG (lectotype here designated).

Geographical distribution. Brazil.

Specimens examined. 18. Brazil. Brasilia, Rio. Jan; Santa Catha.; Parana, 40km. SE Curitiba, Jose dos Pinhais; Porto Alegre; S.C. (Santa Catarina), Sao Joaquin; Vila Velho, PR;1 BMNH specimen without specific locality data, but labeled “257/80.23/ Hyperaspis exclamationis Melly Brasil/ Named by Mulsant.” ( BMNH) ( MHNG) ( USNM).

Other specimens. Three specimens from the DZUP collection labeled as from “( Brazil) Guarapucava, H. Schneider”

Remarks. This little species is surprisingly distinctive because the pronotum is heavily alutaceous; male pronotum entirely black except narrow anterior and lateral borders yellow; and elytron with long, lateral vitta and elongate oval discal spot. Within this group of species it is rather distinctive. “Other specimens” are placed here because 2 of them, both females, have the scutellar and discal spots united into a central vitta.

Mulsant stated that his type was from the Melly collection, some part of which is in the MHNG. Dr. G. Cuccodoro provided a loan of specimens from the MHNG collection, among which was one from the Melly collection recognizable as a type of C. exclamationis . This specimen is here designated as the lectotype.
