(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.
