( Figs. 1 A–D; 2A–C) urn:lsid:zoobank.org:act: BCE8D86C-2368-4F6C-BE98-4CDBDF0D15F3 Type specimen. Holotype : male, Thailand , Nakhon Nayok , Khao Yai , ca. 800 m , 11–19 xi1985 , Chiang Mai , Doi Chang Khian, ca. 1,250 m , 25 x 1985 , leg. Moriuti , Saito , & Arita , gen. slide no. CIS-8169 . Paratype : 13, same data as the holotype. Types are deposited in OPUJ . Diagnosis. This new species is hardly distinguished in its external appearance from P. philosopha Gozmány, 1971 , which was described from N India and P. barathrona ( Park, 2020 ) described from Laos . However, it can be distinguished by the yellowish-white costal patch just beyond middle of the costa. The male genitalia are also similar to those of P. barathrona , but they differ from the latter by the valva having a heavily sclerotized, spine-like process on the ventral margin and the cucullus with a short spine at lower corner, whereas in P. barbathrona the process of valva is short, lacking the horn-shaped spine and the cucullus lacks of a short spine. Description. Male ( Figs. 1 A-D). Wingspan 11.5–12.0 mm. Head : Covered with shiny, yellowish-white scales dorsally. Scape of antenna elongated, creamy white on dorsal surface, brownish anteriorly and posteriorly; flagellum creamy-white, with distinct dark-brown annulations throughout ( Fig. 1C ). Second segment of labial palpus thickened, pale brownish gray on outer surface and paler on inner surface, with white scales at apex; 3rd segment gently upturned, slender, as long as 2nd segment, blackish ventrally creamy white laterally. Thorax : Tegula and thorax pale orange to orange gray. Hind tibia with rough scales beneath. Forewing ground color brownish orange, irregularly scattered with dark-brown scales; a large, irregular-shaped, blackish patch well-developed before middle, disconnected to a trapezoidal patch arising from 2/3 of costa which is followed by a yellowish costal patch; a large, kidney-shaped spot at the end of discal cell, boarded by white scales along outer margin; postmedian line white, convex outwardly before middle; apex sharply produced; termen deeply concave beyond apex, with black scales along margin; fringe brownish orange, with narrow yellowish white basal line, fuscous in its distal half; venation with R 1 arising beyond middle of cell; R 2, R 3, R 4, and R 5 on a common stalk; R 2 arising from basal 1/3; R 3 arising from middle between R 2 and R 4+5 ; R 5 reaching termen; M 2 present; M 3 and CuA 1 coincident; cell more or less triangular, closed. Hind wing pale brownish gray; apex sharply produced, as much as that of gelechiids; inner margin with a broad expansion before 2A; termen concave; venation with M 2 present; M 3 and CuA 1 nearly connate at base. Abdomen ( Fig. 2C ): Spinous zones broadly developed; sternite VIII broad, concave medially on caudal margin. Male genitalia ( Figs. 2A, B ): Uncus short, broad basally, narrowed beyond middle, nearly parallel-sided; apex rounded. Gnathos small. Tegumen weakly sclerotized, roundly concave on anterior margin. Valva broad at base, basal part nearly quadrate, constricted medially; costa straight in basal 1/4, sclerotized, then abruptly oblique, nearly with right angle; ventral margin with a large, spine-like process curved outwardly, followed by a deep emargination; cucullus thumb-like, rounded apically with a short spine at lower corner, dense setose; sacculus narrow, weakly developed. Juxta rectangular, concave on caudal margin, with a small, triangular median plate; lateral margin nearly straight. Vinculum narrow, banded.Aedeagus stout, as long as valva, with arched dorsal margin; bifurcated apically; dorsal margin produced into tounge-like shape and ventral process narrowly produced; cornuti consisting of a long, linear stripe extended from near base to near apex, with a heavily sclerotized, sharply produced apical part, and a broadly elongated plate with numerous strong conical spines dorsally, about 2/3 length of aedeagus. FIGURE 1. Pompographa concaviella Park , sp. nov . : A, adult, holotype; B, ditto, under surface of wings, with names of veins; C, ditto, labial palpus, lateral view; D. ditto, head with antenna. Female unknown. Distribution. Thailand ( Nakhon Nayok ). Etymology. The species name is derived from the Latin, concavus (= arched inward), referring to the termen of the forewing deeply concave beyond apex.
