104. Cyrea ruizi (Bréthes) , new combination

Curinus ruizi Bréthes, 1924:40 ; Korschefsky 1932:252; 1945:451.

Cyra ruizi: González 2008:89 .

Description. Male. Length 2.4 mm, width 1.5 mm; body elongate, slender, parallel sided. Dorsal surface with head, pronotum and elytron smooth, shiny. Color black except head and pronotum yellowish red; elytron with 3 small yellow spots, mediolateral spot irregularly round, discal spot slender, elongate oval, apical spot narrowly, transversely oval ( Fig. 577 ); ventral surface with head, prosternum except apical process, legs yellow; abdomen yellow except median portion of ventrites 1-4 brownish yellow. Head punctures small, separated by a diameter or less, each puncture large as an eye facet; pronotal punctures slightly larger than head punctures, separated by less than to about a diameter, elytral punctures slightly larger than on pronotum, separated by less than to twice a diameter; metaventral punctures as large as on elytron, separated by about a diameter, becoming larger and separated by less than a diameter laterally. Clypeus weakly emarginate apically, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 4 eye facets long, angled forward, apically rounded, reddish yellow. Pronotum narrowed from base to apex, basal and anterior angles abrupt, lateral margin curved, basal margin without trace of bordering line medially. Epipleuron narrow, grooved, not descending externally, deeply emarginate for reception of femoral apices. Protibia with wide oblique angle, basal tooth absent, sponda slightly extended beyond angle ( Fig. 578 ). Carinae on prosternal process widely separated at apex, convergent, joined at basal 1/3 of prosternum, 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 short, rounded throughout, ventrite with sparse, short pubescence and fine, sparse punctures; ventrites 2-6 pubescent throughout, punctures fine, dense; 5th ventrite slightly depressed in median 1/3, apex shallowly emarginate; 6th ventrite depressed medially, apex widely, deeply emarginate. Apical tergite coarsely, densely punctured, apex emarginate. Genitalia with basal lobe about 3/4 length of paramere, symmetrical, sides very slightly convergent from base to apical 2/3, curved to rounded apex; paramere Psc, narrowed from base to apex ( Fig. 579, 580 ); sipho robust, strongly curved in basal 2/3, with visible alae in apical 1/6, basal capsule distinctly sclerotized, inner arm short, wide, apically widened, apex obliquely truncate, outer arm slightly curved, as long and as wide as inner arm, with accessory piece, basal border weakly emarginate ( Fig. 581, 582 ).

Female. Similar to male except genitalia with spermathecal capsule long, slender, basal1/4 enlarged, cornu narrowed to acute apex; bursal cap oval, with 3 sclerotized arms, apical strut short, widened from base to apex ( Fig. 583 ).

Variation. None observed.

Type locality. Chile, locality not stated.

Type depository. Unknown. Not in BMNH or MNHS collections.

Geographical distribution. Chile.

Specimens examined. 2. Chile. Subida C El Roble Caleu -Chacabuco, Región Metropolitana. ( MNHS) ( RH).

Remarks. Cyrea ruizi is known only from Chile, where it is rarely collected (Guillermo Gonzalez, pers. comm.). This is an easily recognized species because of the entirely yellowish red head and pronotum; 3 small, discrete, yellow spots on each elytron, both humeral and scutellar spots absent; and Chilean distribution.

Bréthes originally described it as a species of Curinus , a genus of Chilocorini not at all similar to Cyrea . For several years it was recognized within Chile as a species of Cyra (Cyrea) , and González (2008) formally placed it in Cyra (Cyrea) . This generic disposition is almost certainly correct because the Chilean Cyrea fauna is extremely depauperate, and these specimens fit the original description well.
