Genus
Glodianus
Cameron, 1902
Glodianus
Cameron 1902: 369
.
Type
species:
Glodianus bombycivorus
Cameron, 1902
, by monotypy.
The genus
Glodianus
belongs to the small subtribe
Glodianina
comprising three exclusively Neotropical genera (
Townes 1970: 232
,
Yu
et al
. 2016
). All species of the subtribe are characterized by a small, rectangular or slightly trapeziform areolet in the fore wing (
Fig. 5
), polished first metasomal tergite (
Figs 6, 7
) and ovipositor apex with oblique grooves on dorsal valve (
Fig. 9
). Within the subtribe
Glodianina
,
Glodianus
is easily distinguished from two other genera by having a median compressed horn on the frons (
Fig. 2
).
Glodianus
comprises ten species distributed from
Mexico
to
Venezuela
and
Brazil
, including one species described in this paper and another one resurrected. Seven species of
Glodianus
are restricted to South America and three species are known only from
Mexico
. Nothing is known about the distribution of any species in Central America.
An identification key to all known species of
Glodianus
is provided. However,
Townes (1970: 235)
noted that the genus is large; Central and South American faunas of
Glodianus
require revision, therefore additional comparison of species with their original descriptions or
types
is strongly recommended. Two species,
G. dimidiatus
(Brullé)
and
G. xanthostomus
Cameron
, are known only from males, the
type
of the former species is lost, and original descriptions of both species are brief and incomplete. Thus, these two species cannot be distinguished from each other until the South American fauna of the genus is revised, and therefore both species are placed in one couplet of the key.
