6. Genus Paurotarsus Hancock, 1900

This genus consists of two species: Paurotarsus ruficornis (Walker, 1871) (Fig. 23) and Paurotarsus insolitus Rehn, 1916 with three subspecies,namely Paurotarsus insolitus abbreviatus Grant,1955 (Figs.18, 19); Paurotarsus insolitus extremus Grant, 1955 (Fig. 20) and Paurotarsus insolitus insolitus Rehn, 1916 (Figs. 21, 22) (Grant, 1955 b, 1962, Cigliano et al. 2021). Paurotarsus is characterized by elongate body, antennae with 20-22 segments; well-marked fascial carinae, with a “V” inverted shape; anterior margin of the pronotum (lateral and dorsal view) not hook-like; ventral sinus absence; tegmina elongate, but not broad, being conspicuously as long as the fore femur; mid femur without an internal, dorso-apical spine and macropronotal specimens (Hancock, 1900; Grant, 1955 b, 1962), no brachypronotal form is known. This genus occurs in north part of South America, with records for Bolivia, Peru, Amazon in Brazil, Colombia, Panama, Surinam and Trinidad-Tobago (Fig. 37) (Grant, 1955 b, 1962; Cigliano et al. 2021).

This genus can be distinguished from macropronotal Tetttigidea species and other batrachideines by frontal costa poorly highlighted; fascial carinae well-marked and projecting beyond the eyes in lateral view, with a “V” inverted shape in frontal view; vertex over the eyes; supraocular lobes and fossulas well-marked; anterior margin of the pronotum (lateral and dorsal view) not hook-like; elongate tegmina, ventral sinus absence and hind femur slender.
