Nyctiophylax (Nyctiophylax) catunujah

new species

Nyctiophylax (Nyctiophylax) catunujah   , new species

Figures 69–71 View FIGURES 69–71

Diagnosis: This species resembles N. (P.) archemoros Malicky   from Thailand, and N. (P.) antenor Malicky   from Nepal. It differs from these species in having large rectangular cerci and straight, not curving, ventral paraproctal processes, each with a slightly hooked or knotted apex.

Description: Male. Body uniformly brown. Maxillary palp formula (I,II)-IV-III-V. Forewing length 6.4 mm. Forewings each with median cell open.

Male genitalia. Sternite IX rounded and pentagonal in lateral view ( Fig. 69 View FIGURES 69–71 ); tergite IX fused with paraprocts. Segment X weakly sclerotized, in dorsal view deeply incised into large, quadrangular dorsal interlobular gap with short, irregular, median lobe and long, rod-like lateral lobes; lateral lobes narrow, scarcely setose. Cerci large, quadrangular ( Fig. 69 View FIGURES 69–71 ), setose; arising from complex of tergite IX and paraproct. Paraproctal complexes each consisting of basal body and ventral paraproctal process; smooth, heavily sclerotized, straight with slightly hooked apex. Gonopods robust, each with basal expansion well-developed, representing ventral branch; dorsal branch straight in lateral and ventral views ( Figs. 69, 70 View FIGURES 69–71 ), with dorsoapical incision in lateral view. Phallic apparatus ( Fig. 71 View FIGURES 69–71 ) located dorsally in genitalia, guided by ventral paraproctal processes. Phallic apparatus with tube-like, faintly sclerotized phallotheca continuing into membranous endotheca or endophallus, with pair of long, arching, spines (possibly parameres) arising from phallobase.

Holotype male: MYANMAR: North East , Kambaiti, 7000 ft, 30.iv.1934, Malaise trap, [R. Malaise]— ( BMNH).  

Distribution: Myanmar.

Etymology: Catunujah, quadrangular in Sanscrit, after the quadrangular cerci.

Remarks: Nyctiophylax (P.) archemoros   was placed into subgenus Paranyctiophylax   because it has looped anal veins in the forewing. Nyctiophylax (Nyctiophylax) catunuyah   , new species, has very similar genitalia but the forewing anal veins are not looped.
