Nyctiophylax (Paranyctiophylax) lancelot , new species

Figures 87–89 View FIGURES 87–89

Diagnosis: This species has slender, elongate, unbranched gonopods and no sclerotized dorsal paraproctal processes; sternite IX is strongly produced into a median lobe. Similar genitalic structures are found in N. (P.) icelus (Neboiss) from Sulawesi; N. (P.) nepenthes , new species, from Sabah; N. (P.) padangensis Malicky from Sumatra; N. (P.) pongdiatensis Malicky & Chantaramongkol from Thailand; N. simaritensis Malicky & Chantaramongkol from Sumatra; and N. (P.) temburongensis Malicky from Brunei. The new species is most similar to the latter species, from which it is separated by the presence of oval cerci; gonopods arching uniformly in ventral view, not irregularly bending more abruptly at mid-length; and a lance-shaped spine present on the tip of the ventromesal lobe of each gonopod.

Description: Male. Body pale brown, lighter on less-sclerotized parts. Maxillary palp formula (I,II)-IV- III-V. Forewings light brown with weakly pronounced hyaline windows (1) along crossveins r -m, (2) along crossvein m -cu and (3) on arculus (junction of A1+2+3 with wing margin). Forewing length 4.2 mm. Forewing A1, A2, and A3 looping.

Male genitalia. Sternite IX robust, obliquely elongated-ovoid in lateral view ( Fig. 87 View FIGURES 87–89 ), with welldeveloped apicoventral mesal lobe; tergum IX membranous except for small sclerotized rudiment anterior of fulcrum on each side where sternite IX, paraproctal complex, and cercus meet. Segment X membranous, with single, digitate, hyaline process with terminal, small seta. Cerci large, setose, drop-shaped in lateral view; almost as long as ventral paraproctal processes. Paraproctal complex well-developed, highly sclerotized; each composed of narrow, paraproctal base andlarge ventral paraproctal process horizontal, slightly curving ventrad at apex; dorsal paraproctal process absent. Gonopods elongate, slender, slightly S-shaped in lateral view ( Fig. 87 View FIGURES 87–89 ) evenly curving mesad in ventral view ( Fig. 88 View FIGURES 87–89 ); each with small ventrobasal “elbow” and with mesal lobe bearing strong, straight spine ( Figs. 87, 88 View FIGURES 87–89 ). Phallic apparatus ( Fig. 89 View FIGURES 87–89 ) located dorsally in genitalia, guided by ventral processes of paraproct complexes and membranous segment X. Phallotheca thick, horizontal, convex dorsally to dorsal constriction, then more slender and slightly downcurved; apex of membranous, retracted membranes covered with granules.

Holotype male: MALAYSIA: Sabah: Tawau: Maliau Basin, Nepenthes Camp , crossing stream, 4 ° 43 ’ 58.9 ’’ N, 116 ° 52 ’ 40.7 ’’ E, 994 m, 9.xii.–14.xii.2007, Mega Malaise Trap (6 m long) [B. Viklund & N. Jönsson] ( NHMS). GoogleMaps

Distribution: Malaysia (Sabah).

Etymology: Lancelot, named after the presence of a straight lance-like, long spine on the ventromesal lobe of each gonopod. In the Arthurian and Holy Grail legends, Sir Lancelot is the greatest of King Arthur's knights of the Round Table.
