Cylindronotum Putzeys 1846

Cylindronotum Putzeys 1846:374 . Type species: Cylindronotum aeneum Putzeys 1846:374 (original monotypy). Lectotype selected and labeled by G.E. Ball in MNHP (Muséum National d'Histoire Naturelle, Paris). Type locality: FRENCH GUIANA, Cayenne.

Pseudometabletus Liebke 1930:722 . New synonymy (see notes).

Diagnosis. (cf. Fig. 15). Head and pronotum densely and evenly punctate. Antennomere 4 multisetiferous from basal third to apex, in addition to apical ring setae. Elytron at basal third depressed, without trace of tubercles, without callus at apical third. Male and female with small v­shaped indentation medial on posterior margin of sternum 6. Male endophallus with flagellum; flagellum apex not barbed.

Geographic distribution. A widespread Nearctic and Neotropical genus known from Texas, USA, south to Argentina, east to French Guiana.

Notes. Liebke (1930:723) placed this genus in the Subfamily Colliurinae after his treatment of the genus Calophaena because of the pectinate tarsal claws shared with members of that genus. Since no one has worked extensively with the groups Liebke treated as Colliurinae, the synonymy remained undetected until now. There are 16 species represented in the collections in NMNH, most of which are undescribed.
