Neochauliodes umbratus Kimmins

( Figs. 9 , 40–43 )

Neochauliodes umbratus Kimmins, 1954: 436 .

Neochualiodes furcatus Yang & Yang, 1986: 91 . syn. nov.

Diagnosis. Wings hyaline with median transverse band broad and cloudy. Aedeagus with paired process on subapical portion.

Description. Forewing length 33–59 mm, hindwing length 29–52 mm.

Head gray; vertex with lighter middle portion and black lateral margins. Occiput yellowish brown. Compound eyes brown, ocelli yellow with black inner margin. Antenna dark. Mouthparts yellowish brown except for brown mandibles; maxillary palpus and labial palpus also brown.

Pronotum variable shades of brown; meso­ and metanota dark. Legs brown with short, dense, brown setae; tarsal claws reddish brown. Wings hyaline with cloudy brownish marks; pterostigma short, pale yellow. Forewing with median transverse band pale brown, broad, and extending from C to A; outer margin entirely pale brown. Hindwing similarly marked except for basal half mostly hyaline, and median transverse band shortened, extending from C to M. Veins dark. Rs 5­branched, R2 apically 4­branched, R3 and R4 slightly curved posteriorly near tip; 3 crossveins between R1 and Rs; M 2­branched; 1A 2­ branched.

Abdomen brown. Male tenth tergum ( Figs. 40, 42 ) in lateral view wider than long; in dorsal view apex slightly inflated. Aedeagus ( Figs. 40–41 ) strongly sclerotized, in ventral view slightly narrowing toward apex; in lateral view slightly curved dorsad, with a paired short subapical process directed dorsally. Female eighth sternum subtriangular ( Fig. 43 ) with posterior margin prominent; tenth tergum directed posteriorly, short and claviform with apex slightly inflated; gonapophyses subtrapezoidal ( Fig. 43 ), obliquely directed dorsally.

Distribution. China (Guangdong, Guangxi,); Vietnam.

Remarks. Though this species is similar to N. rotundatus in having the cloudy median transverse bands of both wings ( Tjeder, 1937), it may be distinguished by the strongly modified aedeagus with a pair of short subapical processes. The female wings are much larger than the male. After careful examination of the types of N. furcatus Yang & Yang , there is no significant difference from N. umbratus . Therefore, N. furcatus is herein designated as a synonym of N. umbratus .
