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.
