Colliuris tubulifera ( Bates, 1878)

Casnonia tubulifera Bates, 1878: 604 . Type locality: «Chontales, Nicaragua » (original citation).

Type material. Bates originally described this species from an unspecified number of specimens from Chontales, Nicaragua. He later reported the species also from Cahabon in Guatemala and Volcan de Chiriqui and Bugaba in Panama ( Bates 1883: 162). The BMNH holds seven specimens from Cahabon, Volcan de Chiriqui and Bugaba. One of them, probably a male glued on a cardboard, is labelled " Type H.T. [round label with red trim] / Bugaba, Panama. Champion. / B.C.A. Col. I.1. Casnonia tubulifera, Bates. / Casnonia tubulifera Bates [handwritten]". However, this specimen, as the other ones seen from BMNH, are not part of the original series. The syntype (s) is possibly in the Oberthür collection in MHNP.

Description. COLOR. Head and pronotum black; elytra reddish-black with three small, more or less yellowish spots on each side: one antemedian on medial intervals (extended anteriorly to base along intervals 5 and 6 in one specimen, more or less so in another specimen), one preapical over intervals 5–7 or 5–8, and one almost apical over intervals 1 and 2 or 1–3. Antenna more or less uniformly pale reddish-yellow. Femur reddish-brown to dark reddish-brown; tibia usually paler, yellowish-brown to pale reddish-brown; tarsus yellow with extremity of each tarsomere infuscate. MICROSCULPTURE. Head and pronotum without microsculpture. Proepisternum and prosternum with faint, transverse meshes. Elytra with poorly impressed, isodiametric meshes. Abdominal sterna (except last one) with meshes except over posterior half medially; last sternum with meshes all over. HEAD. Posterior supraorbital seta located in front of level of posterior edge of eye. Frons with rather deep, median impression. PROTHORAX. Pronotum without transverse wrinkles; side without setae. ELYTRA. Interval 3 with three discal setae, interval 5 without discal setae. Strial punctures as in C. bivittis .

Body length: 5.9–6.8 mm.

Geographical distribution. This species ranges from southern Mexico to Panama. I have seen ten specimens from Honduras (Francisco Morazán and Copán Departments), Guatemala (Zacapa Department) and Panama but only a single one from Mexico.

Record. Mexico. CHIAPAS. Tapachula, 21–25.IX.1987, R. Wharton (1ɗ, TAMU).

MARGINESTRIATA GROUP

Isocasnonia Liebke, 1938: 48 , 72. Type species: Casnonia marginestriata Putzeys, 1845 , by original designation.

Diagnostic description. Body without pubescence dorsally. HEAD. Vertex short. Posterior supraorbital seta located at level of posterior edge of eye. PROTHORAX. Pronotum without punctures, with strong transverse wrinkles, without dorsal swelling; lateral groove indistinct; side with three or more setae. Proepisternum and prosternum without punctures. ELYTRA. Lateral edge shallowly, more or less distinctly extended anteriad humerus. Discal setae black, stiff. Intervals 1, 3, 5 and 7 with numerous setae. ABDOMEN. Sterna with very sparse, very small (barely distinct even at high magnification) pubescence; last sternum of male with deep median notch along apical edge.

Note. According to Liebke (1938: 72), the subgenus Isocasnonia also includes C. gratiosa Liebke of Brazil.
