Nyctiophylax (Paranyctiophylax) mintin , new species

Figures 90–93

Diagnosis: The genitalia of this species is similar to those of N. nahum Malicky & Chantaramongkol from Thailand. Nyctiophylax (Paranyctiophylax) mintin , new species is separated from N. (P.) nahum in possessing a pentagonal sternite IX, while in Nt. nahum it is triangular. Furthermore, N. (P.) mintin has clavate cerci, not pointed as in N. (P.) nahum ; and the ventral pair of paraproctal process has straight apices in N. (P.) mintin , while in N. (P.) nahum these processes are geniculate and not turning laterad.

Description: Male. Body uniformly pale brown. Maxillary palp formula (I,II)-IV-III-V. Forewing length 4.0 mm; each with hyaline spots, including short, vertical translucent lunula along crossvein r -m, and large patch around 1st point of bifurcation of M and crossvein m -cu, this latter patch being particularly large in paratypes. Forewing A1, A2, and A3 looping.

Male genitalia. Sternite IX robust, pentagonal ( Fig. 90 ); tergum IX membranous. Segment X membranous, triangular in lateral and dorsal views, visible only on uncleared paratype. Cerci setose, elongate, clavate in lateral view ( Fig. 90 ), slightly shorter than dorsal paraproctal processes. Paraproctal complex welldeveloped, well sclerotized, smooth; each composed of rounded paraproctal base, slender and longer dorsal paraproctal process, and slightly shorter ventral paraproctal process ( Figs. 90, 91 ); bases of opposing ventral processes ventrally produced into rounded plate embracing ventral part of phallic apparatus, forming incomplete, sclerous, subphallic bridge. Gonopods ( Figs. 90, 92 ) slender, bilobed; each with dorsal branch longer than ventral branch; branches narrowing apically. Phallic apparatus ( Fig. 93 ) located dorsally in genitalia, guided by paraproctal processes; phallic apparatus comprising elongate, arch-like, sclerotized phallobase and continuing into membranous endotheca or endophallus; without additional spines or sclerites.
