Diagnosis.
Antennae with thirteen antennal segments in both sexes, antennal organ on the 10th segment. Both sexes brachypterous. Latero-posterior angle of the first three abdominal tergites projecting backwards in females. Cerci of the male specialized, slender, long and curving ventrally at the tip (
Figs. 101–102
). Phallic complex: epiphallus and ectophallus slightly sclerotized, sub-membranous, epiphallic disc narrow and ribbon-shaped. Thick, U-shaped endophallus.
Etymology.
In memoriam of Morgan Hebard, whose many contributions of regional studies, made many orthopteroid taxa known to
Colombia
and a good part of the world.

)
n. comb.
Comments.
This new genus is proposed here based on the results of the current phylogenetic analysis, where
C. atopa
is more closely related to the
Eumastax
+
Homeomastax
clade than with the
Caenomastax
+
Zeromastax
clade in the absence of sclerotization in the dorsal shield, the specialization of the male cerci, the unlobed tegmina for both sexes and the location of the antennal organ.
