NEW SYNONYM
Discussion.
Elkins (1969)
described a new
Harpactorinae
wasp-mimic genus,
Coilopus
, close to
Notocyrtus
Burmeister, 1835
, to include two new species:
C. vellus
and
C. crabrus
, which were very similar to each other. He described the new genus based on specimens from
Brazil
(Amazonas, Goiás, and Mato Grosso) and
Costa Rica
.
Carvalho
et al.
(2001)
described the new genus and species
Notocyrtoides
tuberculatus
(Fig. 1) based on specimens from
Brazil
(Pará, Goiás, Rondônia, and Mato Grosso), mentioning the similarity of their new genus to
Notocyrtus
.
After
Carvalho
et al
. (2001)
publication, the evident similarity between
Coilopus
and
Notocyrtoides
was first noticed by the French entomologist Dr. Jean-Michel Bérenger who kindly communicated this fact to the senior author, and its formal synonymy is presented here.
The synonymy of the two genera is evident if the structure of the legs (Fig. 1) and pronotum (Fig. 2) are compared (see also
Elkins 1969
: his fig. 1,
Carvalho
et al
. 2001
: their fig. 1). The pronotum is enlarged, anteriorly rounded, with a pair of large, blunt, lateral projections; and a pair of smaller projections basal to the nearly quadrangular third lobe (Fig. 1). The legs are relatively long and thin, compared for instance to what is found in
Notocyrtus
.
The structure of the phallus in dorsal view was not clear in the figures presented by previous authors (
Elkins 1969
;
Carvalho
et al.
2001
), therefore new ones are provided here (Figs. 4–5).
Of the two species described by Elkins as
Coilopus
,
N. tuberculatus
can be assigned to
C. vellus
based on the structure of the front tibial spur (Fig. 3), which is elevated (spur is lacking in
C. crabrus
), and by the longitudinal sulcus of the pronotum reaching the hind pronotal lobe (Fig. 2) (not reaching the hind lobe in
C. crabrus
). The identity of
C. crabrus
, nonetheless, is puzzling. This species was described based on a single female from Manaus (Amazonas), and has not been mentioned in the literature, or found in the collections examined by us.
Elkins (1969: 460)
stated that the only differences between the two species of
Coilopus
were the presence of a prominent tibial spur and the shape of the pronotum. The lack of a prominent tibial spur would be surprising, because all species of
Harpactorini
possess it (
Davis 1969
,
Forero
et al
. 2004
,
Weirauch 2008a
). One possibility is that the description of
C. crabrus
was based on a malformed specimen, as has been documented for other “unique”
Reduviidae
species (
e.g
.,
Paramanicocoris
,
Gil-Santana
et al
. 2002
). This has to be corroborated with the study of the
holotype
of
C. crabrus
.
Elkins (1969)
stated that the
holotypes
of
C. vellus
and
C. crabrus
were both deposited in his personal collection. He also stated that some female
paratypes
were deposited at the American Museum of Natural History, New York,
USA
[AMNH]. No specimens of
C. vellus
labeled as
paratypes
were located at the AMNH collection. The fate of Elkins’ personal collection is unknown, and this is worrisome because beside the
holotypes
of the species of
Coilopus
he deposited many other
holotype
specimens of
Reduviidae
there. Elkins used to live in Dallas (Texas,
USA
), and apparently, specimens from his personal collection were neither deposited in the Museum of Dallas nor in the Texas A&M entomological collection [TAMU] (J.C. Schaffner, pers. com.).

Efforts of the junior author to locate the
holotypes
of
C. vellus
and
C. crabrus
have been unsuccessful so far. Only recently, through the kindness of Joseph C. Schaffner (TAMU) the whereabouts of some of the specimens from the Elkins personal collection have been revealed. Among specimens sent back to TAMU by E. R. Hart, were also specimens belonging to Elkins. It is probable that some of Elkins
type
specimens might be in that lot. A detailed study of this collection is in process by Schaffner, and the lot of specimens is going to be permanently deposited at TAMU (J.C. Schaffner, pers. com.).
Distribution.
The genus
Coilopus
is distributed from
Costa Rica
to
Brazil
