Diagnosis. Eyes not reduced (as wide as half of the scapus) and usually pigmented. Pronotum wider than long, with lower margins of lateral lobes moderately expanded laterally. Apterous species. Legs exceptionally long and slender, hind tibia always with 3 dorsal spurs on each side; all tarsi slender and elongated; first tarsomere armed dorsally and as long as a third of its respective tibiae. Abdominal tergites unspecialized and without glandular apparatus. Male epiproctus longer than wide. Cerci slender and barely longer than the hind femur. Ovipositor slightly up-curved, three-fourths as long as the hind femur, with apex dorsally straight, and with very small serrulations. Male genitalia: compact, ectophallic fold membranous and poorly developed; pseudepiphallic median lophi short, and on the posterior lateral borders with a finger-like projection; pseudepiphallic paramere with a cylindrical projection apically; endophallic apodeme membranous and short; ectophallic apodeme thick, ribbon-shaped and upcurved in lateral view ( Fig. 15 A-C).

Taxa included: Otteius thoracicus (Saussure, 1874) .

Comments. This is the genus with the largest known crickets of the tribe, exceeding 20 mm., in contrast to the other Otteiini taxa that do not reach these measurements. The male genitalia resemble more the continental taxa than insular genera, especially the median lophi and lateral lophi of the pseudepiphallus. On the other hand, the first tarsomere armed dorsally of the hind leg is observed in most continental taxa (except Tohila and Hubbellcophus n. gen.), but not in the other two insular genera, these characters suggest a greater association of Otteius with the continental genera than Antillean taxa.
