NEW RECORDS OF DELTOCHILINI FROM ECUADOR (COLEOPTERA: SCARABAEIDAE)

Аннотация

The tribe Deltochilini Lacordaire, 1856 is a tribe of scarabaeid beetles, in the dung beetle of subfamily
Scarabaeinae. Members of the tribe vary widely in size (2—33 mm long). The tribe Deltochilini includes 22 genera.
Species of the tribe are widespread in South America and extend north into the temperate zones of North America. Most
species are coprophagous, some species are saprophagous and feed on rotting mushrooms and plant debris.
During the expedition to Ecuador in the Yasuni National Park and Lalo Loor Dry Forest Reserve in 2018, some data
were obtained on representatives of the family Scarabaeidae, including species from the tribe Deltochilini. As a result of the
research new finds for four species of the tribe Deltochilini are presented (Canthon (Goniocanthon) fulgidus martinezi Nunes
et al., 2018, Deltochilum (Deltochilum) rosamariae Martínez, 1991, Dichotomius (Dichotomius) mamillatus (Felsche, 1901)
and Dichotomius (Dichotomius) podalirius (Felsche, 1901)). Three species (Deltochilum rosamariae, Dichotomius mamillatus
and Dichotomius podalirius) were collected at night under light, and one during the day (Canthon (fulgidus martinezi).
The article illustrates diagnostic features of rare and little-known species (Canthon (fulgidus martinezi and
Deltochilum rosamariae) and indicates some of their ecological preferences. For the first time, Deltochilum rosamariae
is recorded for the Manabí Province and Lalo Loor Dry Forest Reserve.
