Nyctiophylax (Paranyctiophylax) dactylatus n. sp.
( Fig. 2 View FIGURE 2 )
Diagnosis. This new species is very similar to Nyctiophylax (Paranyctiophylax) sagax ( Mey 1995) from Vietnam. It differs in that the preanal appendages are shorter than tergum X and the phallus lacks any spines. In contrast, the preanal appendages of N. (P.) sagax are longer than tergum X and the phallus of that species has a complicated, serrate, longitudinal, subapicoventral “cornutus” of tiny spines.
Male. Length of each forewing 5.6 mm (N=1). Head yellowish brown with dark yellowish antennae, pronotum light brown, meso- and metanota brown, forewings brown.
Male genitalia. Segment IX triangular anteriorly and nearly straight posteriorly in lateral view ( Fig. 2A View FIGURE 2 ); in ventral view segment IX narrowed anteriorly with semicircular excision 1/4 as deep as length of sternum, posterior margin with broad and shallow concavity ( Fig. 2C View FIGURE 2 ); dorsal region of segment IX semi-membranous, rectangular ( Fig. 2B View FIGURE 2 ). Preanal appendages each forming laterally compressed and horizontal lobe, in lateral view ( Fig. 2A View FIGURE 2 ) two times as long as its middle width, broad at base with remainder nearly parallel-sided, tip obliquely truncate; mesoventral process long and stout, broad at base, with apex tapered and curved ventrad, bases of opposing processes meeting each other under phallus ( Fig. 2D View FIGURE 2 ). Tergum X in lateral view long and tall, length 1.3 times height with apicoventral ends triangularly protruded ( Fig. 2A View FIGURE 2 ); in dorsal view transparent, semi-sclerotized, deeply divided apicomesally ( Fig. 2B View FIGURE 2 ). Inferior appendages erect, dorsocaudally olbique in lateral view, each narrowing in distal 1/4 to acute tip; in ventral view, its dorsal edge strongly extended mesad as broad lobe with tip obliquely truncate and with finger-shaped process on inner margin near middle ( Fig. 2C View FIGURE 2 ); basomesal setose lobe small, bluntly triangular, concealed in lateral view by base of appendage, concealed or barely visible ventrally ( Fig. 2C View FIGURE 2 ). Phallus tubular, with pair of laterally compressed and oval protrusions laterally near base and pair of long, needlelike parameres, phallicata without tiny spines ( Fig. 2A View FIGURE 2 ).
Holotype male. Guang-dong Province : Xin-yi County, Da-cheng Town , Da-wu-ling Nature Reserve , upstream of the stream at the entrance of Reserve, N 22°16'08", E 111°11'48", alt. 1110 m, 26 May 2004, Coll. Sun C-h. GoogleMaps
Etymology. Greek, dactylatus = digitate or finger-like, with reference to the finger-shaped process on the inner margin of each inferior appendage in ventral view.
Distribution. Oriental Biogeographic Region of China: Guang-dong.
