Pseudopectinosoma Katovich, new genus, and review of Pectinosoma Arrow (Scarabaeidae: Melolonthinae: Macrodactylini)

摘要

Pseudopectinosoma Katovich, new genus, from Colombia is described and illustrated, with Pseudopectinosoma mesa Katovich, new species, as the type species. The similarly appearing South American genus Pectinosoma Arrow is redefined for comparative purposes. Pectinosoma elongatum Arrow, the type species, is redescribed in a modern sense, the female is described for the first time, and a new distribution record from Venezuela is noted.
