Cadena-Castañeda, Oscar J., 2011, A new genus of cricket near to Miogryllus and Kazuemba from the Colombian Atlantic coast and the first report of Gryllodes sigillatus from Colombia (Orthoptera: Gryllidae: Gryllinae: Modicogryllini), Zootaxa 3126, pp. 55-61 : 56

Faguagryllus n. gen.

Type species: Faguagryllus luteolus n. sp., described below; in tribe Modicogryllini .

Diagnosis. Male brachypterous, with the tegmina covering half of the abdomen; female micropterous with the transparent tegmina partially covering the second tergite. Fore tibia with auditory tympana only exposed on the external face, hind femur with the internal side convex and curving outwards from the ventral margin ( Fig. 1 C). Pseudoepiphallus with the apical margin denticulate, apical region with a wide U-shaped emargination, ectophallus divided ( Fig. 2A & 2 B). Ovipositor 1.1 times as long as the hind femur (Fig. 3).

Comparative notes. Faguagryllus n. gen differs from the two related genera in many features, especially genital morphology and general coloration. In the new genus the pseudoepiphallus has a denticulate apical margin and the body coloration is light, whereas in Miogryllus and Kazuemba the pseudoepiphallus is smooth and the body is dark brown our black.

In Miogryllus the ectophallic apodeme is closed and the apex of the rami uniform, while in the new genus the ectophallic apodeme is separate and the apex of the rami widened.

Miogryllus differs from Kazuemba in having the auditory tympana on the fore tibia only exposed on the external face, the male venation is reticulated; males are brachypterous and females micropterous. In Kazuemba the auditory tympana is absent; the venation is only parallel longitudinal veins connected by very weak transversal veinlets, both sexes micropterous, males without harp and stridulatory file.

Etymology. In honor of Professor Giovanny Fagua at the Pontificia Universidad Javeriana (Bogotá-Colombia).
