( Figs. 14 , 82–89 )

Protohermes hunanensis Yang & Yang, 1992 . Iconography of forest insects in Hunan, China, p. 641. Type locality: Hunan (Yongshun).

Diagnosis. Head entirely black near lateral margins; antenna and mandibles entirely black; pronotum with one pair of blackish vittae on lateral margins; wings dark with distinct whitish markings.

Body length 33–35 mm (male) and 35–38 mm (female); forewing length 35–37 mm (male) and 37–39 mm (female), hindwing length 32–33 mm (male) and 33–36 mm (female).

Head ( Fig. 82 ) yellow without post-ocular spine, dorsally entirely black near lateral margins. Compound eyes brown; ocelli yellow, darkly margined medially. Antennae black. Mouthparts mostly yellow with black mandible. Occiput yellow with one pair of blackish markings on lateral margins.

Prothorax ( Fig. 82 ) yellow; pronotum with one pair of blackish vittae on lateral margins. Meso- and metathorax brown, each dorsally with one pair of blackish spots on lateral sides. Thoracic pilosity yellow, much longer on meso- and metathorax. Legs black with dense, pale yellow, short setae, tarsal claws reddish brown. Forewings ( Fig. 14 ) dark, with 1 large and 1 small whitish markings at base, 2 large and 4 small whitish markings at middle, and 1 distinctly enlarged round whitish marking on apical 1/3; costal cellules with distinct brownish stripes. Hindwings dark except basal half hyaline, respectively with 1 large round whitish marking at middle and apical 1/3. Veins dark brown, except pale yellow veins in whitish markings and base of hindwings. Rs 8 to 9-branched, last branch mostly bifurcate; 10–13 crossveins between R1 and Rs; M1+2 5 to 7- branched, M3+4 3-branched; 1A 3-branched.

Abdomen gray with short, yellow setae. Male ninth tergum ( Fig. 83 ) subtrapezoidal, with parabolic anterior margin and shallowly incised posterior margin. Ninth sternum ( Fig. 84 ) broad; posterior margin with extremely shallow trapezoidal incision, forming two broad roundly produced processes; central portion inflated. Ninth gonostylus ( Fig. 85 ) unguiform and strongly curved dorsomedially. Tenth tergum ( Fig. 86 ) short and subcylindrical, ventrally with one feebly developed tufted tubercle anteromedially; posterolateral corner distinctly and roundly produced; tip slightly incised and densely setose. Tenth sternum ( Fig. 87 ) arched, anterior margin slightly elevated, and posterior incision indistinct; lateral lobes slender digitiform and slightly incurved. Female eighth sternum ( Figs. 88–89 ) strongly sclerotized and subtrapezoidal in lateral view, with truncate posterior margin; ninth segment ( Fig. 88 ) laterally inflated in one pair of small suboval sac-like lobes; ninth gonocoxite valvate and membranous with one digitiform process at tip; tenth tergum short, with posterior margin medially incised, leaving one triangular upper and one subquadrate lower lobe.

Distribution. China (Guangdong, Guangxi, Hunan).

Remarks. Protohermes hunanensis is the only species in P. c o s t a l i s group with dark body coloration and is similar to species of Neurhermes in this respect. The genitalia of P. hunanensis is similar to that of P. fujianensis in having the more trapezoidal male tenth tergum in dorsal view.
