Neochauliodes latus Yang, Gao & An, 2004: 266.
Diagnosis. Head and prothorax entirely yellow. Wings mostly grayish brown with large hyaline marks. Aedeagus strongly widened toward tip in lateral view.
Description. Forewing length 34–36 mm, hindwing length 31–33 mm.
Head entirely yellow. Compound eyes pale brown, ocelli yellow with black inner margin. Antenna black. Mouthparts yellow; maxillary palpus and labial palpus with apices black, mandible with apical half reddish brown.
Prothorax yellow; meso­ and metanota pale brown with lateral margins black. Legs brown, with short, dense, yellowish brown setae; tarsi brown but sometimes darker; tarsal claws reddish brown. Wings grayish brown with large hyaline marks; pterostigma short, pale yellow. Forewing with two or three small spots on basal intercostal area and with entire apical half of intercostal area grayish brown; basal third of wing with spots and diffuse hyaline band; median transverse hyaline band distinct and extending from C to M; apical margin with several small subhyaline spots along longitudinal veins. Hindwing similarly marked; basal half mostly hyaline; median transverse hyaline band subquadrate, much larger than that of forewing. Veins brown. Rs 5­branched, R2 apically 3­branched, R3 and R4 curved backward at tip; 3 crossveins between R1 and Rs; M 2­branched; 1A 2­ branched.
Abdomen dark. Male tenth tergum (Figs. 28, 30) in lateral view subquadrate; in dorsal view apex strongly inflated. Aedeagus (Figs. 28–29) heavily sclerotized, in ventral view suboblong, slightly widened toward tip; in lateral view with apex round and somewhat inflated. Female eighth sternum subtrapezoidal (Fig. 31) with posterior margin prominent; tenth tergum digitiform with pointed tip, obliquely directed dorsally; gonapophyses (Fig. 31) slightly longer than wide, obliquely directed dorsally.
Material examined. Holotype ɗ, CHINA: Guangxi, Shangsi, Hongqilinchang, 350 m, 1999. V.28, G.Q. Zhang (IZCAS). Paratypes: 2 ɗ, CHINA: same data as for holotype (IZCAS); 1 ɗ, CHINA: Guangxi, Shangsi, Hongqilinchang, 300 m, 1999. V.29, X.Z. Zhang (IZCAS). 1 Ψ, CHINA: Guangxi, Jinxiu, 720 m, 1982. VI.10, F. S. Li (CAU); 1 Ψ, CHINA: Guangxi, Jinxiu, 1982. VI.12, C.K. Yang (CAU); 1 Ψ, CHINA: Guangxi, Jinxiu, 1982. VI.17 (CAU).
Distribution. China (Guangxi).
Remarks. This species appears closely related to N. koreanus Weele in having the similar dark wings with large hyaline marks, but can be easily distinguished by the orange head, narrowed apical hyaline marks of the forewings, and the digitiform female tenth tergum. In N. koreanus, the head is brownish, the apical hyaline marks are much wider, and the female tenth tergum is thickened with a produced apical corner (Weele, 1910; Kimmins, 1954).
