Nyctiophylax (Paranyctiophylax) nepenthes   , new species

Figures 94–96 View FIGURES 94–96

Diagnosis: This species is similar to N. (P.) icelus Neboiss   from Sulawesi, N. (P.) padangensis Malicky   from Sumatra, N. (P.) pongdiatensis Malicky & Chantaramongkol   from Thailand, N. (P.) simaritensis Malicky & Chantaramongkol   from Sumatra, and N. (P.) temburongensis Malicky   from Brunei in having slender, ventradcurving ventral paraproctal processes, no sclerotized dorsal paraproctal processes, and a ventroapical median lobe produced posterad from sternite IX. The new species is most similar to N. (P.) icelus   , from which it is separated by its long, clavate cerci; gonopods with their apices excised, not pointed; and 6 stout spines on the endotheca.

Description: Male. Body uniformly pale brown. Maxillary palp formula (I,II)-IV-III-V. Forewing brown, with hypertrophied longitudinal vein R and pronounced hyaline patch pattern of 3 hyaline windows: (1) along crossvein r -m, (2) along crossvein m -cu and point of basal forking of M, and (3) on arculus (at junction of A1+A2+A3 and wing margin). Forewing length 3.0 mm; A1, A2, and A3 looping.

Male genitalia. Abdominal segment IX forming robust sternite, nearly ovoid in lateral view ( Fig. 94 View FIGURES 94–96 ) with well-developed apicoventral mesal lobe; tergum IX membranous, with no narrow sclerotized stripe discernible. Segment X membranous, with pair of long, digitate, hyaline processes weakly discernible in holotype. Cerci setose, narrow, elongate, clavate in lateral view ( Fig. 94 View FIGURES 94–96 ); almost as long as ventral paraproctal processes. Paraproctal complexes highly sclerotized; each including narrow, paraproctal base and large ventral paraproctal processes curving ventrad and bearing 4–6 setae in row on outer surface at vertical apical half; no sclerotized dorsal paraproctal processes discernible; pair of hyaline digitate processes possibly associated with paraproctal complexes. Gonopods elongate, slender, slightly S-shaped in lateral view ( Fig. 94 View FIGURES 94–96 ), arching evenly mesad in ventral view ( Fig. 95 View FIGURES 94–96 ); apices excised in lateral and ventral view; ventrobasal “elbow” absent; base large, bulbous. Phallic apparatus ( Fig. 96 View FIGURES 94–96 ) located dorsally in genitalia, guided by paraprocts and segment X. Phallotheca thick, oriented horizontally; phallothecal sclerotization ending with distinct edge; apex of phallic apparatus membranous, the retracted membranes covered with granules; retracted membranes with row of 4 anterad-directed, stout spines in phallobase and 2 stout spines distally immediately below horizontally oriented, elongate phallotremal sclerites.
