Diagnosis.
This species is distinguished from other species of the
C
.
pluto
species group by the following combination of characters: Length of male frons more than twice that of clypeus (in females one-half times that of clypeus); posterior portion of paraocular area smooth; pronotal transverse ridge quadrilobate with lobes linked by thick carina (
Figs. 10
c, 11a); basal pronotal fossae effaced; elytral interstriae flat; pygidium with wide basal groove; parameres viewed dorsally with wide, flattened subapical teeth.

Description.
Holotype
.
Male (
Fig. 10
c): Length
19 mm
. Humeral width
13 mm
. Completely black.
Transversal frontal carina low and trituberculate. Transverse protuberance on pronotum quadrilobate with lobes linked by thick carina (
Fig. 10
c); protuberance flanked by broad concavities; declivitous surface of pronotum beneath protuberance smooth, devoid of sculpturing. Tooth-like projection in the middle of the basal margin of the pygidium. The parameres of the aedeagus have their teeth backwards hooked.
Allotype. Female.
Length
18 mm
. Humeral width 12.5 mm. Similar to male, but allotype has a low and feeble frontal carina; transverse pronotal carina broadly obtuse, vaguely indented at anterior median edge; surface behind carina shallowly concave, transverse depression summit weakly bitumid.
Variation.
Six specimens examined, four males and two females. Length
18–20 mm
. Humeral width
12–13 mm
. In smaller males the transverse pronotal protuberance is only evident as a thickening.

Habitat.
Tropical moist forest, altitudinal distribution
120–790 m
, collected from June to July, with flight interception and carrion traps.
Geographical distribution (
Fig. 16
).
The new species is presently known from central
Panama
, distributed in the provinces of Colón,
Panamá
, and the Canal Zone.
Chorological affinities.
C. gephyra
, represents a geographical and morphological bridge, between
C. kohlmanni
to the north and
C. morenoi
to the south of its central Panamanian distribution. It is also found in tropical moist forest, as are the other two species.
Taxonomic relationships.
This new species was originally, partly, and erroneously considered to be
C. ohausi
by
Howden & Young (1981)
and as a Panamanian variation of
C. morenoi
by
Edmonds & Zidek (2010)
. In reality, a species complex exists (
Fig. 16
), where
C. kohlmanni
is distributed from
Nicaragua
to northwestern
Panama
(Bocas del Toro),
C. gephyra
is distributed in central
Panama
, and
C. morenoi
is distributed from southeastern
Panama
(Darién) to
Ecuador
. All three species are very similar in their morphological characters.
Etymology.
A Greek word in apposition,
gephyra
(
γέφυρα), meaning bridge, in reference to the fact that it acts like a bridge to the distribution of two similar species,
C. morenoi
in South
America
and
C. kohlmanni
in Central
America
.
