Nyctiophylax (Paranyctiophylax) anosib , new species

Figures 72–75

Diagnosis: This species has a mesoventral branch on the gonopods developed into a large lobe. These lobes are each accompanied by slender dorsal and ventral paraproctal processes. Most Afrotropical Nyctiophylax species have similar gonopods, and N. (P.) anosib , new species, is distinguished from the other species in that the gonopods have larger ventral branches and a narrower interlobular gap.

Description: Male. Body uniformly dark brown. Maxillary palp formula (I,II)-IV-III-V. Forewing length 4.3 mm. Forewings each with anal veins A1, A2, and A3 looped.

Male genitalia. Abdominal segment IX reduced to robust sternite, rounded in lateral view, especially anteriorly ( Fig. 72 ); tergum IX membranous, with no narrow sclerotized stripe discernible. Segment X membranous, small triangular, almost as long as gonopods in lateral view ( Fig. 72 ) and apically truncate in dorsal view ( Fig. 73 ). Cerci setose, narrow, elongate in lateral view, slightly curving mesad in dorsal view, as long as dorsal paraproctal processes. Paraproctal complexes well-developed, highly sclerotized, smooth; each composed of (1) paraproctal base (anterior body formed by meeting point of dorsal and ventral paraproctal processes) narrow, (2) dorsal paraproctal process slender, slightly longer, laterad-curving, and (3) ventral paraproctal process slightly shorter, curving, and tapering. Gonopods ( Fig. 72, 74 ) robust, broad, each with well-developed dorsal and mesoventral branches; dorsal branch long, curving dorsad in lateral view; mesoventral branch shorter, resembling thumb of mitten, especially in ventral view; apices of dorsal and ventral branches blunt. Phallic apparatus ( Fig. 75 ) located dorsally in genitalia, guided by paraproctal processes; forming simple tube with apical membranes and without visible sclerites or spines.

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

Distribution: Madagascar.

Etymology: Anosib, after the type locality.
