Identification.
This species can be distinguished from other
Eurysternus
species
, by the pronotum with eleven more or less clear calluses, some of the calluses of the middle region are not very shiny; metaventrite with a foveolate in the middle in males; posterior aspect of the male metafemur has a small tooth located towards the middle, and in the females there may or may not be a tooth (
Génier 2009
).
Distribution.
In
Colombia
it has been reported from
Antioquia
, Bolívar,
Boyacá
,
Cesar
,
Magdalena
,
Meta
,
Norte de Santander
, and
Tolima
(
Génier 2009
; Camero-R 2010). It is found in dry and humid habitats, both forest and open habitats (
Génier 2009
), at elevations between
100–1050 m
a.s.l. (
Medina et al. 2001
). In the Colombian Orinoco region, the species is restricted to elevations between
200 to 600 m
a.s.l. (
Medina and Pulido 2009
). This rare species was found between
700–900 m
a.s.l. in the study area, and was represented by 17 individuals, predominantly open areas of wooded grassland (13 individuals), and less abundant in open grassland (three individuals) and in the high secondary forest (
one specimen
). The species was observed during times of both greater and lesser precipitation.
