Hebardomastax Cadena-Castañeda n. gen.

http://lsid.speciesfile.org/urn:lsid: Orthoptera .speciesfile.org:TaxonName:470303

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.

Type species. Hebardomastax atopa ( Hebard, 1923) 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.
