Orotettix Ronderos & Carbonell, 1994: 88 ; Eades et al., 2015.

Type species. Paradichroplus andeanus Bruner, L. , by original designation.

Diagnosis. Small (males 12.8–16.7 mm; females 17.6– 22.2 mm) brachypterous insects. Fastigium prominent, with median sulcus; frons slanted; pronotum with lateral borders slightly divergent at metazona; hind margin of pronotum disc straight or slightly rounded; hind femur proximally wide; tegmina not surpassing the second abdominal segment, not overlapping dorsally; male cerci robust at base, tapering towards the apex, slightly curved towards the epiproct; subgenital plate conical with acute apex; phallic complex ( Fig. 5A, B ): apical valves of aedeagus thin, slightly curved upwards, with the apices slightly overlapped or touching each other; sheath of aedeagus with lateral and median dorsal lobes.

Closely related to Coyacris Ronderos but differing as follows: smaller size, tegmina narrower and shorter, not overlapping dorsally, and if so only slightly overlapped, without raised median longitudinal vein; postocular band mostly indistinct; male cerci not compressed at distal portion; apical valves of aedeagus not strongly up-curved, without membranous expansions, with the apices if overlapped, only slightly; sheath of aedeagus with lateral lobes and without transverse flange; ectophallus less sclerotized; epiphallus with narrower lateral plates and lophi not so largely developed.

Distribution: Peru (Ayacucho, Arequipa, Apurimac, Cusco, Puno) and Bolivia (La Paz) ( Fig. 1 ).
