Nyctiophylax (Paranyctiophylax) kilah , new species

Figures 83–86

Diagnosis: This species has triangular gonopods as in N. (P.) africanus Kimmins from East Africa and N. (P.) aurorae Gibon and N. (P.) brenguesi Gibon , from West Africa. This new species is easily distinguished from those 3 species by its bifurcate apex of each ventral paraproctal process.

Description: Male. Body uniformly dark brown. Maxillary palp formula (I,II)-IV-III-V. Forewing length 6.0 mm. Forewing anal veins A1, A2, and A3 looping.

Male genitalia. Abdominal segment IX reduced to robust sternite, nearly triangular in lateral view, with pronounced ventroapical mesal process ( Fig. 83 ); sclerotized tergite IX narrow, tall, each side fused to paraproctal base. Dorsal and ventral paraproctal processes fusing at paraproctal base. Segment X membranous, well discernible; small and triangular in lateral view ( Fig. 83 ); apically cut, with shallow mesal concavity in dorsal view. Cerci setose, narrow, elongate in lateral view, slightly curving mesad ( Fig. 84 ); slightly longer than dorsal paraproctal processes ( Fig. 83 ). Paraproctal complex highly sclerotized, smooth; each composed of (1) paraproctal base narrow, fused to narrow tergite IX; (2) dorsal paraproctal process slender, long, and laterad-curving; (3) ventral paraproctal process short, arching ventrad, with bifurcate apex for which ventral arm tapered, spine-like. Gonopods ( Fig. 83 ) robust, broad, nearly triangular, each with small mesoventral branch; dorsal branch long, curving caudad; apices of dorsal and ventral branches tapering. Phallic apparatus ( Fig. 86 ) located dorsally in genitalia, guided by paraproctal processes; simple, with thick phallobase, slender distal membranes without visible sclerites or spines; apex dark.

Holotype male: MADAGASCAR: Anosibe, “km 57 route”, 1955 [R. Paulian]—( MNHN).

Paratypes: Same data as holotype — 1 male ( MNHN), 1 male ( OPC) .

Distribution: Madagascar.

Etymology: Kilah, road in Sanscrit, referring to Road 57 km from the city of Anosibe, where this species was collected.
