Larvae of
Hologymnetis
Martínez
The larval description of
Hologymnetis cinerea
(Gory and Percheron)
that follows is the first for the genus. Larvae of
Hologymnetis
(to the extent known based upon only one species) are most similar morphologically to those of
Cotinis
species.
Larvae of
Hologymnetis
have the tarsungulus with seven setae, a maxillary stridulatory area with five irregularly spaced, low teeth, and the last segment of the antenna with three ventral sensory spots. Larvae of
Cotinis
have a tarsungulus with 10–12 setae, a maxillary stridulatory area with 7–9 regularly spaced, high teeth, and the last segment of the antenna with 5–13 ventral sensory spots.
The genus
Hologymnetis
consists of seven species that are found from the southwestern
United States
to southern
Brazil
; the genus was revised by Ratcliffe and Deloya (1992). Adults of
Hologymnetis
species
have been found in the detritus piles of leaf cutter ants (
Atta
sp.
) and are known to feed on rotting fruit, flowers, and the sap of several trees and shrubs (
Baccharis
and
Acacia
species
). Like other gymnetines, the larvae feed in compost and rotting wood. It is not known whether the adults are obligate myrmecophiles or whether the larvae are also found in ant nests.
