Account

What the sources say about this taxon, as written.

Bioacoustics · Plazi

Bioacoustics. All gryllacridids produce sound by a femoral-abdominal stridulatory apparatus, formed by parallel rows of pegs on the lateral side of tergites and a row of pegs on the adjacent inner side of the hind femora. Sound producing is only used as a defence if the crickets are threatened. Tympana are absent in this cricket family ( Rentz and John 1989 ).

Diagnostic notes · Plazi

Diagnostic notes. Raspy Crickets ( Gryllacrididae ) are plump, non-jumping crickets with soft, fleshy bodies and nocturnal behaviour. They are often sandy-coloured (Fig. 185 ). Glomeremus capitatus resembles G. pileatus in almost all aspects, including the male abdominal terminalia. The main characteristics of G. capitatus are the typical black pattern on the pronotum and more extensive black markings on the antennae, abdominal tergites and legs (Fig. 187 ), compared to G. pileatus . There are subtle differences in the genital plate in males of both species: rounded mainly with a slightly truncated apex in G. capitatus and trapezoid in G. pileatus (Fig. 188 ). In females, there is a clear difference in the subgenital plate. In G. capitatus , females have elongated lobes with a rounded apex. In G. pileatus , they are much shorter, square and sharply notched (Fig. 189 ). The width of the head is not a good characteristic for separating both species, contrary to Uvarov (in Uvarov and Popov (1957) ) and Popov (1984) . In both species, the head is wider than the pronotum. Uvarov (in Uvarov and Popov (1957) ) and Popov (1984) state that, contrary to G. pileatus , G. capitatus does not have stridulatory pegs on the side of its tergites. However, an examination of the specimens G. capitatus collected at Skand and Zerig in 2012 shows the presence of those pegs on the second and third tergites, both in males, females and late instar nymphs.
