Paragryllus elapsus Desutter-Grandcolas, 1992a: 151 .

REMARK

Two subspecies have been separated in P. elapsus (see Desutter-Grandcolas 1992a) to acknowledge variations in size, coloration, male stridulatory file, female ovipositor length and female copulatory papilla. The only female at hand ( Fig. 29C ) does not fully fit neither of the subspecies, and its status will have to be reconsidered with additional specimens.

TYPE LOCALITY. — French Guiana, aval du saut Pararé ( Paragryllus elapsus elapsus Desutter-Grandcolas, 1992 ) and Sinnamary ( Paragryllus elapsus incertus Desutter-Grandcolas, 1992 ).

Allotype. French Guiana • 1 ♀; same locality and collector as the holotype; 12.VII.1988; MNHN-EO-ENSIF5139.

Paratypes: 1 male, 1 female: French Guiana • 1 ♂ 1♀; same locality and collector as the holotype; VII.1988; MNHN-EO-ENSIF5140, 5141. Paragryllus elapsus incertus Desutter-Grandcolas, 1992 : Holotype by original designation. French Guiana • 1 ♂; Sinnamary; VII.1977; M. Descamps leg.; MNHN-EO-ENSIF5142 .

Allotype. French Guiana • 1 ♀; same locality, date and collector as the holotype; MNHN-EO-ENSIF5143.

Paratype, 1 male: French Guiana • 1 ♂; same locality, date and collector as the holotype; MNHN-EO-ENSIF5144 .

MATERIAL FROM THE MITARAKA. — French Guiana • 1 ♀; Monts Tumuc-Humac, Massif du Mitaraka vers sommet en Cloche; entre 54.4541 O 2.2349 N et 54.4646 O 2.2329 N; alt. entre 370 m et 470 m; 23.II.-10.III.2015; F. Legendre & S. Hugel leg.; fn. SH458, de nuit; MNHN .

REMARK

Compared to the two subspecies, the female at hand differs by the small size of its ovipositor, well shorter than FIII and TIII (longer in P. elapsus elapsus and P. elapsus incertus ), its larger size, the shape of its copulatory papilla (short, not concave laterally, bisinuous distally, Fig. 23M, N ) and details of coloration, such as area between eyes light yellow, this coloration prolonged on occiput; LL black, with a short median yellow line along lower margin; DD yellowish marked with brown and black, with a wide longitudinal, median yellow band bordered distally by a pair of Y-shaped black spots, muscular inscriptions marked with black ( Fig. 29C ).

TIII serrulation: spines lacking between subapical spurs and apical spurs on both sides; on inner side, one spine between isa1 and isa2, one to two spines between isa2 and isa3, 20 spines above isa3; on outer side, one to two spines between osa1 and osa2, two spines between osa2 and osa3, 18-19 spines above osa3. Barsitarsomeres III serrulation: one to two inner spines and five to six outer spines, in addition to apical spines. Subgenital plate as on Fig. 23O.

MEASUREMENTS (IN MM). — See Table 21 .
