Bioacoustics of Latitatagraecia vulgivaga

Differential diagnosis. Male . Differs from L. kalamaya principally in the shape of the cercus ( Figs 14 H-J), the dark colour of many specimens, the presence of the dark patch on the outer pagina of the hind femur ( Fig. 14A ) and the elongate paraprocts of the male ( Fig. 14C ). The internal margin of the male cercus is minutely serrate (not easily seen in Fig. 14J ). Female. The subgenital plate is broader than long; cercus conical, expanded basally. Ovipositor shorter than length of hind femur ( Table 4 ), gracefully upcurved. Colouration. The overall colour of this species is very dark, especially on the pinned specimens. The head is very dark, especially in the region of the genae. The pronotum is almost uniformly black in some specimens. The outer pagina of the hind femur is usually dark ( Fig. 14A ) or light with an elongate dark stripe. Habitat. This species seems to prefer the dry leaf litter and dead twigs under eucalypts. Seasonal occurrence. L. vulgivaga occurs from late spring and probably extends its activity into summer. Stridulatory file. Fig. 20H . The stridulatory file comprises 19 principal teeth with the usually few small teeth at the distal end. The proximal teeth are rather widely spaced. Song. The calling song of this species has not been documented. Karyotype. Not documented.
