Ptenidium Erichson 1845

Blackwelder (1944–57) lists 8 species of Ptenidium occurring in Central America : concinnum from St. Vincent and Grenada, foveatum from Mexico and Guatemala, fuscipenne from Panama, nitens from Nicaragua, and ignobile, impunctatum, obesum and strangulatum from Guatemala . With the exception of fuscipenne described by Motschulsky, all these specimens were collected by G. Champion and described by A. Matthews (1872). The types of all the Matthews species are in BMNH and were examined and found to be different species from the Costa Rican specimens. The only other species of Ptenidium known from Central and South America are those from Peru described by Darby 2016, who erected a new subgenus, Peruvium, to accomodate several species bearing patches of posteriorly directed setae at the hind angles of the pronotum and globular spermathecae.
