Review of the genus Scythropiodes Matsumura, 1931 (Lepidoptera, Lecithoceridae, Oditinae) from China, with a checklist of the world Author Wang, Qingyun Author Li, Houhun text Zootaxa 2016 4132 3 301 329 journal article 38684 10.11646/zootaxa.4132.3.1 e5293b23-d0ea-4af1-9790-956999278df7 1175-5326 258365 C4EC42F8-77B4-4151-AB10-3F3FB4111911 Scythropiodes dorsoprocessus Wang et Li , sp. nov. Figs 11 , 26 Diagnosis. This new species can be distinguished from its congeners by the valva bearing a stout thumbed process dorsally. It is similar to S. gnophus and S. barbellatus in the ground color of the forewing, but can be separated by the forewing having a discocellular spot and a streak at the end of the cell ( Fig. 11 ), and in the male genitalia by the transtilla bearing papillary lateral lobes, and the phallus having a curved cornutus ( Fig. 26 ). In S. gnophus and S. barbellatus , the forewing has neither a discocellular spot nor a streak ( Figs 9, 10 ); in the male genitalia the transtilla bears no lateral lobes and the phallus lacks a cornutus in S. gnophus ( Fig. 25 ); and the transtilla has a pair of leaf-like lateral lobes and the phallus has two cornuti in S. barbellatus ( Fig. 24 ).

Head with frons greyish white, vertex dark brown. Antenna greyish white on scape and on base of flagellum, gradually deepening to yellowish brown toward end. Labial palpus with second palpomere greyish white except distal 1/2 dark brown on outer surface; third palpomere about same length as second, pointed terminally, yellowish white on outer surface, dark brown on inner surface, with a black ring at base. Thorax and tegula dark brown. Forewing with costal margin slightly arched, apex obtuse, termen obliquely truncate; ground color dark brown, costal margin pale orange; discocellular spot black; black streak from below discocellular spot to distal 1/4 of dorsum; several black dots along termen; cilia greyish white, speckled with dark brown. Hindwing pale grey; cilia grey, pale orange and scale-like from base to tornus, basal line yellowish white. Foreleg dark brown; midleg with femur yellowish white, tibia and tarsus yellowish brown; hindleg with femur yellowish white, tibia and tarsus pale yellowish brown. Male genitalia ( Fig. 26 ). Ventral plate of gnathos as long as basal arm, heavily sclerotized, tapering to pointed apex. Valva with basal 3/4 subparallel, distal 1/4 narrowed gradually to apex, with a tiny spine apically; stout thumbed process beyond 2/ 3 in dorsal surface near ventral margin, with a tuft of long scales, about half width of valva; costa narrow, sclerotized, distal 1/3 extending obliquely ventrad to above ventral margin near apex, membranous beyond distal 1/3. Transtilla broad, narrowed medially; lateral lobes papillary, with short hairs. Sacculus dorso-medially with clustered long hairs and protruded triangularly toward costa. Juxta membranous, with a pair of triangular lateral processes. Vinculum U-shaped. Phallus gently narrowed toward apex, about 1/2 length of valva; cornutus S-shaped, extending from base to before apex. Female unknown. Distribution. China (Guangxi) . Etymology. The name of this species is derived from the Latin dorso- (dorsal) and processus (process), referring to the valva with a thumbed process dorsally in the male genitalia.
