Figures 22–24

Type material. Holotype: 3 ( SYSU), China: Guangdong Prov., Lianxian, 3–VI–1998, coll. Chen Zhenyue. Paratype: 13 ( SYSU), China: Hong Kong, 26–V–1935, collector unknown.

Description (male). Head ( Fig. 22 A–B) mostly black, with large dark red triangular mark basally and medially in dorsal view, as long as pronotum and slightly narrow than base of mesonotum; clypeus red; postclypeus protruding anteriorly, moderately long than vertex in dorsal view; compound eye fuscous; ocellus orange. Distance between lateral ocellus and corresponding eye as long as distance between lateral ocelli. Face dark brown; gena and lorum with tuft of golden hairs; rostrum black, extending to apex of mid coxae.

Pronotum ( Fig. 23 A) black; nearly trapezoid, with golden hairs, dark reddish median longitudinal fascia constricted at middle in dorsal view; symmetrically with four oblique fissures in addition to several transeverse carinae; pronotal collar yellowish brown; anterolateral margin not dentate; lateral angle of pronotal corner well developed. Mesonotum ( Fig. 23 A) black, slightly narrower than pronotal collar, with dark reddish median longitudinal fasciae and golden hairs in dorsal view. Cruciform elevation dark red. Ventral surface of thorax black.

Legs ( Fig. 23 E) reddish brown; fore femur with primary spine prostrate, lying flat; secondary and subapical spines erect, sharp and short.

Fore wing ( Fig. 22 A–B) with basal half mostly brown, apical half hyaline. Hind wing ( Fig. 22 A–B) hyaline.

Abdomen ( Fig. 22 A–B) cylindrical and mostly black in dorsal view, as long as distance from head to cruciform elevation, with short brown hairs and dark reddish median longitudinal fasciae. Timbal cover ( Fig. 23 D) black, small and triangular. Timbal ( Fig. 23 D) largely exposed, with nine ribs and eight intercalary ribs; caudal seven ribs fused at base. Ventral surface of abdomen dark red. Operculum ( Fig. 23 C) yellowish brown, short, obliquely semicircular, not extending to anterior margin of sternite II, with tympanum largely exposed; opercula very narrowly separated from each other.

Genitalia ( Fig. 24 A–D). Pygofer oval in ventral view; dorsal beak very long, protruding upwards in lateral view; distal shoulder broadly rounded and convex submarginally, forming distinct submargin in lateral view; basal lobe of pygofer undeveloped; upper lobe of pygofer long and stout, with somewhat triangular-shaped process ventrally in lateral view (as signed by thick arrow in Fig. 24 C); accessory tooth of pygofer ( Fig. 24 C) distinct and slender in lateral view. Clasper in ventral view with median clasper process remarkably long, narrowed apically and slightly curved laterally; lateral clasper lobe short and round. Prominent lobe-like process at both sides of base of aedeagus short. Aedeagus with seven short to long spine-like processes apically and subapically, the most basal process separated from other processes in lateral view.

Female: unknown.

Measurements (23). Length of body: 3 14.0–15.0; length of fore wing: 3 16.0–17.0; width of fore wing: 3 5.0–5.5; width of head including eyes: 3 3.0–3.5; width of pronotum (including pronotal collar): 3 4.5–5.0; width of mesonotum: 3 3.5–4.0.

Biology. Unknown.

Distribution. China (Guangdong).

Etymology. The specific name is after the locality of the holotype.

Remarks. This new species was identified incorrectly as M. conica in the collection of NWAFU, but can be distinguished from the latter and other species of Mogannia by the presence of the slender accessory tooth of male pygofer and the somewhat triangular-shaped ventral process of the upper lobe of pygofer.
