Bioacoustics of Paracophus

Diagnosis. Eyes not reduced (as wide as half of scapus) and normally pigmented ( Fig. 3 , 5 ). Pronotum subquadrate, little broader than long, anterior and posterior margins weakly concave, side margins broadly convex with anterior portion wider than mid-portion, lower parts of lateral lobes separated from disk by a shallow curved impression ( Fig. 7A, E, I ). Male tegmina mostly covering by pronotal disc, thickened, very short and broad, covering the weakly sclerotized mesonotum, their distal margins gently convex, outer and inner angles rounded, inner margins slightly overlapping; venation indistinct; stridulatory file present and functional ( Fig. 7A, E, I ). Female tegmina reduced to minute oval lateral rudiments, often hidden under the edge of pronotum. Legs relatively short and stout, hind tibia with four dorsal spurs on each margin; all tarsi slender and elongated, first tarsomere armed dorsally and as long as a third of its respective tibiae ( Fig. 3A , 5A ). Abdominal tergites unspecialized (glandular apparatus present); male epiproctus subtriangular, as wide as long, with straight margins and rounded apex ( Fig. 3B , 5D ). Cerci slender and barely longer than the hind femur ( Fig.3 , 5 ). Ovipositor slightly decurved, three-fourths as long as the hind femur, apex dorsally rounded and distally sharp ( Fig. 3E ). Male genitalia: tubuliform and elongate; ectophallic fold membranous; pseudepiphallic median lophi with a medial notch and, on the posterior lateral borders, with a spine-shaped projection that curves upward in lateral view; pseudepiphallic paramere with three projections, one ventrally and two posteriorly; endophallic apodeme moderately sclerotized, with cartilaginous appearance and connected to endophallic sclerite which is well sclerotized; ectophallic apodeme slim, curved in lateral view and parallel one branch with the other ( Fig. 4 , 6 ). Taxa included: Paracophus subapterus Chopard, 1947 ( Type species), P. velazquezi n. sp. and P. victoriensis n. sp.
