Stegenagapanthia aureomaculata Chiang & Li, 1984: 97 , 100, fig. 2 (type locality: “ Changning , Yunnan, China ”).

Redescription. Male. Body length: 10.0– 13.2 mm, humeral width: 3.0–5.0 mm (22 individuals); one specimen ( Figs 1–3 , 7–8, 11–22 ), body length: 11.0 mm, humeral width: 3.5 mm. Body reddish brown, basal 1/3 of antennomere IV, antennomeres V–X (except for apex) and antennomere XI yellowish brown, antennomeres III–X dark brown apically; prothorax (except for dorsal apex), elytra (except for suture, apical 1/6 and periphery of the yellow setal marks), mesoventrite, sides of metaventrite and urosternites I–II black ( Figs 1–3 ).

Frons sparsely covered with short yellow and black setae ( Fig. 7 ), antennal tubercles, scape (except ventrally), pedicel (except ventrally) and apical 3/5 of antennomere IV moderately with dense short black setae, antennomeres IV–X with several long black setae ventrally and with several short black setae apically; scape (ventrally), pedicel (except dorsum) and antennomere III with sparse short grayish white setae; basal 2/5 of antennomere IV with moderately dense short light-yellow setae ( Figs 1–3 ). Each elytron with three irregular yellow setal spots on basal 1/3 close to suture and with sparse short light yellow setae at apex inside ( Fig. 1 ). Prosternum and mesoventrite sparsely covered with short light-yellow setae, metaventrite sparsely covered with semi-erect brown setae ( Fig. 2 ).

Antennae 1.7 times as long as body, antennal formula (ratio) based on length of antennomere III: scape= 0.48, pedicel= 0.08, IV= 0.89, V= 0.61, VI= 0.53, VII= 0.52, VIII= 0.45, IX= 0.40, X= 0.34, XI= 0.42. Inner side of antennomeres VI–X triangularly processed near base ( Figs 1–2 ). The raised portion on pronotum slightly notched posteriorly ( Fig. 8 ). Elytra 2 times as long as wide at base. Hind wing with Cu vein connected with a short cross vein near the middle, MP 3+4 and MP 4 veins closed to each other, r4 vein connected with sr vein in the middle ( Fig. 11 ). Urosternite V sub-truncate apically ( Fig. 2 ).

Male terminalia. Tergite VIII ( Figs 12–13 ) sub-hexagonal, truncate apically. Stem of spiculum gastrale more than 2 times as long as branches ( Figs 14–16 ), hook-like basally in lateral view ( Fig. 15 ). Tegmen ( Figs 17–19 ) shorter than penis, dorsum of parameres nearly glabrous, only covered with several short thick brown setae near apex; phallobase expanded near apical 1/3 and gradually tapered to base, then curved near the basal 1/ 6 in lateral view ( Fig. 18 ). Dorsal struts of penis slightly curved and constricted near base in profile ( Fig. 21 ).

Female. Similar to male, except for body length: 11.0–16.0 mm, humeral width: 4.0– 5.4 mm (11 individuals); one specimen ( Figs 23–26 ), body length: 11.0 mm, humeral width: 4.0 mm. Antennae 1.3 times as long as body, antennal formula (ratio) based on length of antennomere III: scape= 0.59, pedicel= 0.11, IV= 0.84, V= 0.57, VI= 0.46, VII= 0.37, VIII= 0.32, IX= 0.27, X= 0.22, XI= 0.24. Elytra 2 times as long as wide at base. Hind wing with shorter CuA 2 vein, MP 3+4 and MP 4 veins far from each other, sr vein absent ( Fig. 26 ). Urosternite V densely covered with brown setae apically, slightly depressed at apical half and notched apically ( Fig. 25 ).

Intraspecific variation. The variation occurs mainly in body color: males with head, antennae, elytra (suture, apical 1/6 and periphery of the yellow setal marks), metaventrite (middle), ventrites III–V, and legs reddish brown ( Figs 1–3 , 7 ) or yellowish brown ( Figs 4–6 , 9 ); prothorax black ( Fig. 8 ) or reddish brown ( Fig. 10 ). Females with pronotum reddish brown ( Fig. 23 ) or dark reddish brown ( Fig. 24 ), elytra reddish brown ( Fig. 23 ) or black at basal half except periphery of the yellow setal marks ( Fig. 24 ). In both sexes the amount and shape of yellow setal marks on elytra varies.
