Apiomerus nitidicollis
Stål, 1872
(
Figs. 1–2
)
Apiomerus nitidicollis
was described based on specimens from “Brasilia borealis” [= north
Brazil
] (
Stål 1872
).
Apiomerus pulchripes
Walker, 1873
, downgraded to a junior synonym of
Ap. nitidicollis
by
Distant (1903)
, was described based on specimens from Northern
Brazil
too. Besides Brazilian specimens,
Costa Lima
et al
. (1951)
and Gil-Santana
et al
. (2003) mentioned a female and a male of this species from
Suriname
and
Colombia
, respectively.
Stål (1872)
named two varieties to
Ap. nitidicollis
based on the color of the coria of hemelytra: “
var.
nigripennis
”, with the hemelytra completely black and “
var.
discopterus
”, with the central portion of the coria golden yellowish (“croceo”). Photos of a male
syntype
deposited in the NHRS has been made freely available at: http://www2. nrm.se/en/het_nrm/d/apiomerus_discopterus.html. According to these images, the central portion of the coria of the hemelytra are reddish to pale reddish, similarly to an individual examined here (
Fig. 1
). It is possible that in other specimen(s) examined by C. Stål, the central portion of the coria were paler as mentioned in his description, similarly to another specimen studied (
Fig. 2
). Gil-Santana
et al
. (2003) emphasized the high similarity in dimensions and general coloration between specimens of
Ap. nitidicollis
with hemelytra bicolored (“
var.
discopterus
”) to another member of
Apiomerini
,
Calliclopius nigripes
(
Linnaeus, 1767
)
, whose record from
French Guiana
is confirmed here. In both species, the head, thorax and fore legs are black, while the middle and hind femora and tibiae, and the abdomen are pale yellowish to reddish. These similarities make plausible to suppose that they share a mimetic model, including sets of variation in color (see below).

The
two males
examined here agree well with the descriptions and diagnosis of
Ap. nitidicollis
(
Stål 1872
,
Walker 1873
,
Costa Lima
et al
. 1951
) (
Figs. 1–2
). A remarkable characteristic of this species is the strongly curved apices of middle tibiae (
Stål 1872
,
Costa Lima
et al
. 1951
) (
Fig. 1
).
