Prays dorsiprotrusa Li , sp. nov.
( Figs. 18 View FIGURES 17 – 22 , 34 View FIGURES 29 – 34 )
Type material. CHINA: Holotype ♂, Liaoning Province: Heshangmaozi, Benxi , 25.VI.2010, coll. Jiayu Liu and Yanpeng Cai, genitalia slide No. CPX15142.
Diagnosis. This new species is similar to P. inconspicua Yu et Li, 2004 , P. helanshana sp. nov. and P. delta Moriuti, 1977 by having a unicolor forewing. Prays dorsiprotrusa sp. nov. can be distinguished from the latter three species in the male genitalia by the socius with basal half expanded quadrangularly, which is gradually narrowed to apex in the latter three species. The male genitalia of the new species are extremely similar to those of P. beta Moriuti, 1977 , but it differs in the gnathos protruded triangularly at middle on the posterior margin, the valva protruded at about distal 1/5 on the dorsal margin and forming a triangular process, and the S-shaped sacculus; in P. beta , the gnathos is narrowed medially, the valva has a thorn before apex on the dorsal margin, and the sacculus is nearly straight ( Moriuti, 1977: Plate XXII, fig. 249).
Description. Adult ( Fig. 18 View FIGURES 17 – 22 ) with wingspan 13.0 mm. Head greyish brown except frons mixed with white. Labial palpus brown. Antenna greyish brown except scape white on ventral surface. Body greyish brown; forewing mixed with dark brown. Foreleg with femur white on dorsal surface, mid- and hindlegs with coxae and femora white, remaining part greyish brown. Abdomen greyish brown on dorsal surface, yellowish white on ventral surface.
Male genitalia ( Fig. 34 View FIGURES 29 – 34 ): Socius with basal half expanded quadrangularly, distal half very narrow, hooked inwards, narrowed to pointed apex, bearing dense long setae. Tegumen medially extended for half length of lateral band, anterior margin deeply concave at middle, protruded in triangle laterally; lateral band oblique outwards anteriorly. Gnathos slightly narrowed at middle, its posterior margin protruded triangularly at middle and folded downwards across anterior margin. Valva almost evenly broad from base to basal 1/3, separated from sacculus from about 1/3, uniformly narrow from 1/3 to before apex, narrowly rounded at apex, protruded at about distal 1/5 on dorsal margin, somewhat forming a triangular process, bearing long setae; transtilla thorn-shaped, extending almost horizontally, medially connected by a sclerotized quadrate plate; sacculus S-shaped, approximately half length of valva, covered with long setae along ventral margin, distal 1/3 gradually narrowed, extending ventrad freely, pointed at apex; membranous area between sacculus from basal 1/3 to 2/3 and valva. Vinculum U-shaped; saccus nearly same length as socius, slightly widened distally, rounded apically. Juxta semicircular; anellus lobe thumb-like, arising from inner margin of juxta posterolaterally, extending obliquely downwards, nearly touching each other. Aedeagus about 1.3 times length of valva, straight, basal 1/3 widened, distal 2/3 slightly narrow and parallel; cornuti consisting of a slender thorn and a cluster of numerous spinules, about 2/5 length of aedeagus, placed medially.
Female unknown.
Distribution. China (Liaoning).
Etymology. The specific name is derived from the Latin dors- and protrusus, referring to the valva protruded triangularly at about distal 1/5 dorsally in the male genitalia.
