Description. Body small, narrow, delicate, with yellowish tan. Head: about as wide as pronotum ( Fig. 1B ), yellow, shiny, without any trace of vittae or markings, eyes large and black, faint central ocellus, clypeus pentagonal, the last segment of maxillary palps triangular. Pronotum: setose, with anterior margin concave and the posterior margin straight, latero-anterior lobe more pronounced than latero-posterior ( Fig. 1A ). Legs: fore femora subcylindrical and armed with three apical spines, auditory tympana of fore tibiae exposed on the external margin. Fore and middle femora compressed; hind femora robust, hind tibiae dorsally with five external and four internal spurs, additionally three apical ones are present on both sides. Sternum: Prosternum unarmed with the posterior margin constricted, hence the coxae close together; mesosternum rectangular with posterior margin obtuse-angled; metasternum broader than mesosternum, slightly expanded and covering base of posterior coxae, posterior margin constricted and convex. Wings: Brachypterous, tegmina as long as pronotum, harp whith three parallel cross-veins and two longitudinal veins covered from the lower-basal region of the stridulatory file, two veins of superior margin of the base stridulatory file. Abdomen: setose, cerci as long as hind femur. Internal genitalia: main body of pseudoepiphallus with a deep U-shaped posterior invagination coupled to a pair of broad and denticulate projections, pseudoepiphallic apodemes small and triangular. Ectophallic arch and ectophallic apodeme separate, rami not fused and with widened apex.

Female: (Fig. 3) Similar to the male; micropterous, ovipositor well developed, compressed with enlarged apex.

Distribution. Only known from rural zone in Cartagena de Indias, Bolívar department. Colombian Atlantic coast.

Etymology. (Latin) luteolus – of yellow, referring to the yellowish tan of this species.

The first report of Gryllodes sigillatus from Colombia. Otte’s proposal (2006) on the status of the species of the genus Gryllodes is well founded, but some of the images are confused. The images referred to as G. sigillatus actually correspond to the neotype of G. supplicans therein designated; both the habitus and the genitalia. The fully winged individuals Otte referred to G. supplicans and the brachypterous to G. sigillatus . Subsequently he discovered the female holotype of G. s u p p l i c a n s in the Natural History Museum in London (Otte 2009), which makes the neotype designation invalid.

Gryllodes sigillatus is a species with cosmopolitan distribution (Eades et. al.). In Colombia it is widely distributed, apparently in locations from 0 to 1800 m, showing that this species prefers warm and temperate climate. The species is not common, and can be found in forests and in secondary vegetation.
