Microcanus minor ( Bates, 1885 )

Nearns, Eugenio H., 2019, A new genus and species of Onciderini Thomson, 1860 (Coleoptera: Cerambycidae: Lamiinae) from Ecuador, with notes on additional taxa, Insecta Mundi 701 (701), pp. 1-7 : 4

Microcanus minor ( Bates, 1885)

= Oncideres paurosoma Noguera, 1993 ; syn. nov.

Remarks. Oncideres paurosoma Noguera, 1993 was described from four specimens (one male, three females) from Guerrero and Oaxaca, Mexico. Taricanus minor Bates, 1885 was described from a series of specimens collected in Jalapa (Veracruz), Mexico. Dillon and Dillon (1945) later proposed the genus Microcanus for this latter species. Examination of the female lectotype specimen of M. minor (BMNH) and a female paratype specimen (ACMT) of O. paurosoma revealed no characters to separate the two species ( Fig. 2 a–d). Based on the absence of morphological features to separate the two species and similar distribution, Oncideres paurosoma Noguera, 1993 is synonymized with Microcanus minor ( Bates, 1885) .
