discussion
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. 23 M, 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. 29 C). TIII serrulation: spines lacking between subapical spurs and apical spurs on both sides; on inner side, one spine between isa 1 and isa 2, one to two spines between isa 2 and isa 3, 20 spines above isa 3; on outer side, one to two spines between osa 1 and osa 2, two spines between osa 2 and osa 3, 18 - 19 spines above osa 3. Barsitarsomeres III serrulation: one to two inner spines and five to six outer spines, in addition to apical spines. Subgenital plate as on Fig. 23 O.
discussion
REMARK Two subspecies have been separated in P. elapsus (see Desutter-Grandcolas 1992 a) to acknowledge variations in size, coloration, male stridulatory file, female ovipositor length and female copulatory papilla. The only female at hand (Fig. 29 C) does not fully fit neither of the subspecies, and its status will have to be reconsidered with additional specimens.
