COMPLEMENT OF DESCRIPTION

General morphology

TIII serrulation lacking between subapical spurs 1 and 2 on both sides; on inner side, no spine between isa2 and isa3, two to five spines (mean 3.75) between isa3 and isa4, 9-14 (mean 11.25) spines above isa4; on outer side, one to two spines (mean 1.75) between osa2 and osa3, four spines between osa3 and osa4, 11-14 (mean 12.25) spines above osa4. Barsitarsomeres III serrulation: no inner spine and two outer spines, in addition to apical spines.

Coloration

Face coloration as on Fig. 18A . Male

FWs as on Fig. 18B . Metanotum with two rounded glandular areas ( Fig. 18C ).

Male genitalia

As on Fig. 18 D-F.

Measurements (in mm)

See Table 12 .

Variation

The two males from Mitaraka correspond to the description of A. spelaea , except for their larger size (see Table 12 ). The number of stridulatory teeth of their file (496 teeth, n= 1) fits the upper number found in the type series (385-495 teeth, mean 459, n= 11). Their FWs have the particular shape found in the species, but lateral part of dorsal field is much longer ( Fig. 18B ). Their male genitalia are also similar, though larger ( Fig. 18 D-F). Slight variations in coloration include, in one or both males, entirely dark LL, variously dark cerci, one or two yellow spots near anterior margin of supra anal plate, and entirely dark subgenital plate.

CALLING SONG
