Ordo: Coleoptera
Familia: Curculionidae
Name
Microzurus Heller, 1895: 13 – Wikispecies link – Pensoft Profile
Type species
Microzurus rhombus Heller, 1895 [by monotypy].
Gender
Masculine.
Diagnosis
Microzurus can be differentiated from Copturus by the lack of a ventral tooth on the profemora, a thin fifth tarsomere with minute tarsal claws (Fig. 58), and costate elytral intervals. Champion (1906: 89) described two species that have shallow or absent modification to the mesoventrite – no material was observed of the species without modification (M. edentatus Champion, 1906), but the species would still be easily recognized as a Microzurus by the concealed scutellum, minute tarsal claws, and absent ventral tooth on the pro- and mesofemora. The second funicular article is not longer than the first and the hind femora are carinate and ventrally toothed. The observed species have a similarly apically laterally flanged receptacle of the mesoventrite as in Copturus, though it is usually much less prominent.
Phylogenetic relationships
Hespenheide (1984)[1] suggested a relationship between Microzurus and Cylindrocopturinus. Microzurus is here interpreted as closely related to Copturus, but the position of those two genera within the lechriopines is uncertain. See entry on Copturus.
Host associations
Hespenheide (1984[1]: 316) reported the possibility of seed-feeding based on label data. Costa-Lima (1956[2]: 219) mentions South American species on fruits of Campomanesia Ruiz & Pav. and Psidium guajava (Myrtaceae).
Described species
Three species are known from the focal region and an additional four species are known from South America (Wibmer and O’Brien 1986[3]: 266).
Range
Mexico, Belize, El Salvador, Honduras, Panama; South America.
