Colliuris marginestriata (Putzeys, 1845)

Casnonia marginestriata Putzeys, 1845: 371 . Type locality: « Mexico (Oaxaca)» (original citation). Colliuris marginestriata: Liebke (1930: 665) .

Type material. Putzeys original description of C. marginestriata was based upon a single specimen. The holotype, which I have not seen, is not in the Institut Royal des Sciences Naturelles de Belgique, Bruxelles (Jacques Cools, pers. comm.) but probably in collection Chaudoir in MHNP (see Chaudoir 1872: 406).

Description. COLOR. Body black dorsally with faint blue green lustre; antennomere 1, in some specimens also 2, brown to reddish-brown, antennomeres 3 and 4, in some specimens also 2, paler, yellowish, antennomeres 5–11 dark reddish-brown; femur with basal third to basal half yellow, apical half or more brown or reddish-brown, tibia more or less yellow with apex slightly infuscate. MICROSCULPTURE. Frons and vertex with poorly impressed isodiametric to transverse meshes. Pronotum, proepisternum and prosternum with transverse meshes. Elytra with granulate microsculpture (meshes irregularly isodiametric and sculpticells convex) at base, at apex and on intervals 7–9, in some specimens also on intervals 5 and 6, leaving remaining of disc smooth, contrastingly shiny. PROTHORAX. Pronotum with three or four lateral setae on each side. Proepisternum and prosternum with transverse wrinkles over entire surface. ELYTRA. Intervals 1, 3 and 5 with 7–14 discal setae, interval 7 with six to nine discal setae. Striae impunctate, not impressed over smooth area, impressed laterally over microsculptured area. MALE GENITALIA. Median lobe as illustrated (Fig. 6).

Body length: 6.4–7.8 mm.

Geographical distribution. I have seen this species only from Mexico where it ranges from Chihuahua to Chiapas (Fig. 26).
