Abstract

Corotoca Schiødte, 1853 is a Neotropical genus of termitophiles beetles, with five species, and its description marks the first record of insects associated with termites. A new species, Corotoca fontesi sp. nov., from Brazil, is described and illustrated, and a taxonomical problem regarding to the identification and nomenclatural status of two species, Corotoca phylo Schiødte, 1853 and Corotoca seeversi Fontes, 1977, is solved. Therefore, Corotoca seeversi is proposed as a new junior synonym of C. phylo, and the material identified as C. phylo housed in the Museum of Zoology of the University of São Paulo, Brazil (MZUSP) is recognized as a new species, Corotoca fontesi sp. nov. New morphological and sexual dimorphism data in the species, and solution of some messy informations about the genus present in the literature are also present.

Keywords: Coleoptera, dimorphism, illustrations, morphology, taxonomy, termitophiles

[Entomology • 2010] Eocorythoderus incredibilis • A new genus and species of flightless, microphthalmic Corythoderini (Coleoptera: Scarabaeidae: Aphodiinae) from Angkor Wat, Cambodia, associated with Macrotermes termites

Abstract

Eocorythoderus incredibilis, a new genus and new species, of Corythoderini is described. This new species was found in fungus gardens of Macrotermes gilvus (Hagen, 1858) in Angkor Wat, Cambodia. The new taxon is a flightless, microphthalmic species and the first corythoderine associated with Macrotermes Holmgren, 1910. The beetles were observed being carried by worker termites. Eocorythoderus is probably closely related to the genera Corythoderus Klug, 1845 and Paracorythoderus Wasmann, 1918 (also Corythoderini). Some character states shared with the distantly-related termitophilous scarab genus Termitotrox Reichensperger, 1915 (Termitotrogini) are noted, and proposed as convergent. 

Key words: Termitophile, fungus garden, Odontotermes, Oriental region, convergence

Eocorythoderus new genus

Type species. Eocorythoderus incredibilis new species, here designated.

Etymology.  A combination of  Eos, the Greek goddess of the dawn, and Corythoderus, the type genus of 

Corythoderini, in reference to the new taxon having the eastern-most distribution of the genera in the tribe. Gender: masculine.
