Paraeulioptera Massa , new genus. Figs. 15–20

Type species: Paraeulioptera emitflesti n. sp., here designated

Diagnosis. Characterized by fore femora flattened, long legs, open tympana and tegmina translucent.

Description. General habitus. Head and antennae. Fastigium of vertex narrower than first antennal segment, not contiguous with fastigium of frons, sulcate above. Eyes circular, prominent, face smooth, higher than wide. Thorax. Pronotum smooth, higher than long, with a well-developed humeral excision, lateral lobes widely rounded. Legs. Long, fore coxae armed with a fine spine, fore femora flattened laterally, fore and mid femora unarmed, hind femora armed, fore and mid tibiae ventrally armed, genicular lobes of hind femora armed with two spines on inner and outer margins. Open tympana on inner and on outer margins of fore tibiae. Tegmina translucent, narrow, welldeveloped, shorter than hind wings. Stridulatory area marked. Styli present.

Etymology. The name Paraeulioptera means that it is related to Eulioptera Ragge, 1956 .

Remarks. Paraeulioptera n. genus is related to Eulioptera and to Phaneroptera Serville, 1831 . According to Ragge (1980), the genus Eulioptera is closely related to Phaneroptera , but has translucent tegmina and has not styli, while the number of apical spurs on each side of hind tibiae is variable (two or three; one species with only one spur has been moved to the genus Pigalua Massa, 2017 ).
