Bioacoustics of Otteiini

Key to Otteiini genera 1. Tegmina present with different degrees of development ( Fig. 1 , 3 , 5 ). Female macropterous ( Fig. 2 ).................... 2 – Tegmina absent in both sex ( Fig. 9 , 10 , 12 )................................................................. 3 2. Lateral lobes of pronotum not expanded laterally and without carinae dividing the pronotal disc of the lateral lobes ( Fig. 1B ). Male tegmina covering about half of the abdomen and without stridulation file ( Fig. 1A ). First tarsomere of the hind tibia, unarmed dorsally and as long as half of the hind tibiae ( Fig. 2 )............................................. Tohila – Lateral lobes of pronotum expanded laterally, separated from the pronotal disk by a shallow curved carina. Tegmina of the male covering the mesonotum, and with functional stridulation file ( Fig. 3 , 5 ). First tarsomere of the hind tibia, armed dorsally and as long as a third of hind tibiae ( Fig. 3A ).................................................. Paracophus n. sensu. 3. Normal size eyes for the tribe, larger than half of the scapus width and pigmented. Non-specialized tergal segments, with or without dorsal glands. Male epiproctus variable in shape, but without lobes on the lateral-distal borders................. 4 – Eyes remarkably reduced, small than half of the scapus width, and with reduced pigmentation, or absent ( Fig. 10 A-D). Usually with plate-like extensions on the tergal segments of moderate size or very conspicuous and/or with dorsal glands ( Fig. 10 E-J). Male epiproctus quadrangular with finger-like lobes on the latero-distal borders ( Fig. 10 E-H)....... Hubbellcophus n. gen. 4. Hind tibiae with two subapical spurs; first tarsomere of the hind legs not serrated on the dorsal margins. Glandular organs present on the third and fourth tergites......................................................................... 5 – Hind tibiae with three subapical spurs; first tarsomere of the hind legs serrated on the dorsal margins. Glandular organs absent................................................................................................ 6 5. Pseudepiphallic median lophi apex with notch deep and narrow, or very shallowly concave; rami shorter to slightly longer than ps.m.; ectophallic fold very long, clearly exceeding over ps.m apex and strongly arcuate in lateral view ( Fig. 15 D-F)................................................................................................. Cubacophus – Pseudepiphallic median lophi apex with notch semicircular, rami much longer than ps.m; ectophallic fold much shorter, not reaching ps.m apex and not arcuate in lateral view................................................. Dominicophus 6. Medium-sized, less than 20 mm . The hind femur is relatively short and stout; hind tibia with a variable number of dorsal spurs, from 3 to 4 on the outer side and 1 to 5 on the inner side. Male epiproctus wider than long............................ 7 – Large-sized, more than 20 mm . The hind femur is relatively long and slender; hind tibia always with 3 dorsal spurs on each side. Male epiproctus, noticeably longer than wide.......................................................... Otteius 7. Lateral lobes of pseudepiphalus rounded, protruding upwards, and with denticulations all over the dorsal border. Pseudepiphallus fused in dorsal view ( Fig. 13 D-F, 14C-E).............................................. Venegascophus n. gen. – Lateral lobes of the pseudepiphalus not produced upwards and without denticulations. Pseudepiphallus divided in dorsal view, and without connection ( Fig. 14 F-H)....................................................... Hortacophus n. gen.
