ETYMOLOGY. — Species named after the shape of pseudepiphallic apical lobes in male genitalia, which resembles the ears of a rabbit ( cunicula, in Latin ). Name in apposition.

DIAGNOSIS. — Within the genus, small species close to P. subaptera n. stat. by the lack of developed FWs in males and females, and by the general shape of male and female genitalia. It is characterized by its male genitalia (pseudepiphallic sclerite long and very narrow, more so than in P. subaptera n. stat.; pseudepiphallic lobes very long and wide, twisted over their length, resembling rabbit ears; pseudepiphallic parameres short, the lower part narrowed toward apex, the upper part short and broadly squared), its low number of dorsal spines on TIII and basitarsomere III, and its female genitalia (lateral margins rounded in dorsal view, dorsal aperture narrowed distally).

DESCRIPTION

In addition to the characters of the genus (Desutter-Grandcolas 1992b).

General morphology

Size small. Maxillary palpi not very elongated ( Fig. 25A ); article 3 shorter than article 4, article 5 the longest. DD posterior margin largely concave ( Fig. 25C ). TI with a small inner tympanum; outer tympanum absent. FIII with filiform apical part. TIII lacking spines between subapical spurs and apical spurs on both sides; on inner side, no spine in male and females between isa1 and isa2, and between isa2 and isa3, three spines in male, two spines in females between isa3 and isa4, five spines in male, three to five spines (mean 4.2) in females above isa4; on outer side, one spine in male and females between osa1 and osa2, two spines in male and females between osa2 and osa3, five spines in male, four to five spines (mean 4.4) in females between osa3 and osa4, eight to ten spines (mean 9) in male, nine to 12 spines (mean 10.2) in females above osa4. Barsitarsomere III serrulation: no inner spines in male and females; two outer spines in male, three outer spines in females, in addition to apical spines.

Coloration

Face ( Fig. 25A ) variably yellow, from almost fully yellow below antennal pits to light brown with large yellow spots and indistinct brownish areas close to epistomal suture and below anterior angles of eye; with a yellow line below median ocellus, bordered with a black line and separated from antennal pit by a short light yellow and light brown coloration. Cheeks light yellowish, with light brown area behind posterior margin of eye. Fastigium black ( Fig. 25C ), ocelli ivory. Head dorsum black; vertex with five indistinct yellow longitudinal lines ( Fig. 25C ). Anterior side of scapes with a transverse yellow spot, surrounded with black brown. Antennae brown, apical margin of articles yellow. Maxillary palpi very light yellow or brown, last three articles marked with brown on lateral sides ( Fig. 25A ). Pronotum: anterior margin light brown; DD ( Fig. 25C ) with a wide longitudinal yellow band over its whole length, bordered by two wide black spots close to anterior margin, and an irregular yellow band on each lateral margin; DD otherwise light brown, black brown and black, with yellowish posterior margin; LL black, lower margin bordered with light brown ( Fig. 25B ). Metanotum with a yellow, longitudinal band, bordered by two lateral black brown spots, prolonged on tergites I and II by a very thin line. Legs: TI, TII yellow, lower side light ochre; four black rings. FI, FII light yellow, inner and outer lower margins black; one and two (respectively) black rings in distal half; a large black patch on each side and several small black spots dorsally and laterally. FIII yellow with black brown pattern: outer side with many oblique black stripes and a longitudinal black line close to lower margin; two black rings on apical filiform part; inner side less marked with dark brown. TIII black brown with a bright yellow transverse line close to the knee; irregular yellow flecks on the sides, more or less prolonged dorsally. Spurs and claws yellowish with brown apex. Tarsomeres 1 brown with yellow base; tarsomeres 2 and 3 light brown. Cerci light brown.

Male

Antennae without bunches of strong and long setae. Apterous. Supra anal plate brown with two indistinct transverse yellowish spots at base. Subgenital plate brown; very long, going beyond supra anal plate distal margin by half of its length.

Male genitalia ( Fig. 25 D-F)

Pseudepiphallic sclerite very narrow dorsally, abruptly raised anteriorly. Pseudepiphallic apical lobes very wide and flat, separate by a narrow U-shaped depression. Pseudepiphallic parameres small; lower part wider on its outer side, acute distally; upper part close to midline, broadly squared. Rami wide, slightly concave, widened anteriorly and posteriorly. Ectophallic apodemes reaching only rami mid length; apex abruptly widened, triangular and acute.

Female

Apterous, without even flap-like FWs laterally. Supra anal plate brown with yellowish base. Subgenital plate short, transverse; distal margin straight, not sinuate. Ovipositor very short, shorter than FIII; apex outer sides very faintly crenulated, almost smooth.

Female genitalia ( Fig. 23 G-I).

Copulatory papilla small, close to that of P. subaptera n. stat., but apical two-third of the papilla more rounded than quadrangular in dorsal view, lower and straighter in side view; dorsal aperture regularly narrowed toward distal margin; apex small, with a distinct sclerotized edge.

Measurements (in mm)
