Zenoria carbo González & Santos , sp. nov.

Figs. 32–45

Diagnosis. Z. carbo sp. nov. resembles a group of species with a long subtriangular penis guide, about 3 times longer than wide, and parameres with setae only at the apex. Other species that have these features are Z.

circumcincta Gordon, 1971 ; Z. emarginata Gordon, 1971 ; Z. linteolata Mulsant, 1850 and Z. purpurea Gordon, 1972 . The new species differs from Z. circumcincta in the more elongated phallobase (3 times longer than wide) and the parameres parallel sided with a straight outer margin in ventral view. It is distinguished from the other species by having a penis guide with a sinuous inner margin in lateral view. Apart from this, all other species are predominantly lighter in color (with or without dark spots on the elytral disc), except Z. linteolata and Z. purpurea , which have a dark metallic-green and dark metallic-purple elytra respectively.

Description of holotype, male. Length 3.2 mm; width 2.6 mm. Body oval, convex ( Figs. 32–33 ). Head and prothorax pale yellow; antennae and mouthparts brown; pubescence yellowish white ( Fig. 34 ). Pronotum with basal black spot occupying central ¾ of base and extending to middle; pubescence yellowish white, about half scutellar shield length ( Figs. 32–34 ). Elytra black, shiny with yellowish-white pubescence, except central medial area with inconspicuous dark-brown pubescence ( Figs. 32–35 ). Scutellar shield black ( Fig. 32 ). Epipleuron black, inner carina extending half distance to outer margin. Meso- and metaventrite black. Legs pale yellow. Abdominal postcoxal line curved posterolaterally, closely paralleling posterior margin of ventrite for short distance, then abruptly redirected anteriorly toward base of ventrite in lateral third ( Fig. 36 ). Posterior margin of ventrite V with smooth emargination. Posterior margin of ventrite VI with wide emargination, accentuated medially, deep ( Fig. 37 ). Phallobase long, ½ length of tegminal strut, three times longer than wide ( Fig. 37 ). Penis guide triangular in dorsal view, nearly three times longer than wide, sides almost parallel, slightly narrower in apical fourth; apex rounded ( Figs. 39–40 ); in lateral view triangular, inner margin slightly sinuous ( Figs. 42–43 ). Parameres projecting slightly beyond penis guide ( Fig. 39 ), in ventral view subtriangular with straight lateral margins, directed slightly inward in distal 1/5 ( Fig. 41 ), regularly curved in lateral view and parallel sided. Sparse short setae at end of paramere ( Figs. 42–43 ). Penis normal, wide, no more than 40 times longer than wide, semicircular in basal 3/5, straight in apical 2/5, except apex recurved upward relative to penis capsule, with membranous areas on outer side, fewer on inner side ( Figs. 44–45 ); penis capsule with inner branch slightly longer than outer branch, curved inward, narrow at base and widening to 2/3 of length with membranous areas, outer branch with almost parallel sides, truncated, with outer membranous area ( Fig. 44 ).

Female. Unknown.

Variation. Length 3.1–3.2 mm; width 2.5–2.6 mm. The pale yellow coloration of the pronotal anterior margins may be reduced to ½ or ¼ of the size.

Etymology. From Latin " carbo " meaning coal, referring to the intense black color of the elytra; proposed as a noun in apposition.
