Description of two new species in the genera Epectinaspis Blanchard and Strigoderma Burmeister (Coleoptera: Scarabaeidae: Rutelinae: Anomalini)

“…The morphological characters, terms, and criteria used are those of Paucar-Cabrera (2003) for Epectinaspis and Bader (1992) and Delgado & Mora-Aguilar (2012) for Strigoderma.…”

Synopsis of the New World Genera of Anomalini (Coleoptera: Scarabaeidae: Rutelinae) and Description of a New Genus from Costa Rica and Nicaragua

“…Epectinaspis (e.g., Fig. 1h) is a neotropical genus with its species distributed from southern Mexico to northern Venezuela at elevations ranging from 10 to 2,500 m. This genus is comprised of nine species (Paucar-Cabrera 2003), and its species are characterized by a mesepimeron that is partially visible anterior to the base of the elytron (in dorsal view; Fig. 23), a mesometasternum that is not produced anteriorly beyond the base of mesocoxae (Fig.…”

“…40), males with apex of clypeus moderately reßexed, maxilla with six teeth, mandible with two small, sharp teeth (second tooth biÞd), and anterior angles of pronotum covering posterior one-third of eye. Phylogenetic analyses (Paucar-Cabrera 2003) demonstrated that the genus Epectinaspis was paraphyletic, and species were included in two clades: the "Epectinaspis clade" (with nine species) and an "undescribed clade" which represented a new genus of Anomalini (with one species of Epectinaspis transferred into this new taxon). Phylogenetic analyses showed that Strigoderma is the sister group of Epectinaspis (Paucar-Cabrera 2003).…”

Phylogenetic analyses showed that Strigoderma is the sister group of Epectinaspis (Paucar-Cabrera 2003). Morphological character examination revealed that Strigoderma species are distringuished from Epectinaspis species by the following characteristics: mesepimeron subtriangular and weakly exposed beyond elytra in Epectinaspis (Fig.…”

“…With the addition of the new genus described herein, the New World Anomalini includes 16 genera and Ϸ320 species. Modern taxonomic treatments are available for three of these genera: Dilophochila Bates (six species, Moró n and Howden 2001), Strigoderma Burmeister north of Panama (28 species, Bader 1992), and Epectinaspis Blanchard (nine species, Paucar-Cabrera 2003). The monotypic genera Nayarita Moró n and Nogueira, Yaaxkumukia Moró n and Nogueira, and Mazahuapertha Moró n and Nogueira were recently created, and treatments for these are available (Moró n and Nogueira 1999).…”
