( Figs. 12 , 67–74 )

Protohermes fujianensis Yang & Yang, 1999 . Fauna of Insects in Fujian Province of China, Vol. 3, p. 171. Type locality: Fujian (Chong-an).

Diagnosis. Head with one pair of brown markings laterally; pronotum with one pair of dark vittae on lateral margins; forewings pale brown with several whitish markings; male ninth sternum with trapezoidal posterior incision; male tenth sternum with lateral lobes distinctly incurved.

Body length 27–29 mm (male) and 30–31 mm (female); forewing length 36–37 mm (male) and 41–45 mm (female), hindwing length 32–34 mm (male) and 36–41 mm (female).

Head ( Fig. 67 ) yellowish brown without post-ocular spine, dorsally with one pair of brown markings on lateral sides. Compound eyes brown; ocelli pale yellow, darkly margined medially. Antennae black with scapes and pedicel pale yellow. Mouthparts yellow; mandible with distal half black. Occiput yellowish brown with one pair of brownish markings laterally.

Prothorax ( Fig. 67 ) pale yellow; pronotum with one pair of dark vittae on lateral margins, sometimes narrowly divided midway. Meso- and metathorax yellow. Thoracic pilosity yellow, much longer on meso- and metathorax. Legs dark with dense yellowish short setae; coxae, trochanters and basal tibiae pale yellow; tarsal claws reddish brown. Forewings ( Fig. 12 ) pale brown, with 1 round whitish marking at base, 2 round whitish markings at middle and 1 distinctly enlarged, whitish round marking on apical 1/3; costal cellules with distinct brownish stripes. Hindwings pale brown except basal half subhyaline, respectively with 1 round whitish marking at base, middle and apical 1/3. Veins pale brown, except veins in whitish markings pale yellow. Rs 9 to 11-branched, last branch bifurcate; 10 crossveins between R1 and Rs; M1+2 4 to 8-branched, M3+4 2 to 4- branched; 1A 3-branched.

Abdomen dark with yellowish short setae. Male ninth tergum ( Fig. 68 ) subtrapezoidal, with arched anterior margin and shallowly incised posterior margin. Ninth sternum ( Fig. 69 ) broad with arched lateral margin, posterior margin with shallow trapezoidal incision, forming two large roundly produced apical processes; central portion inflated. Ninth gonostylus ( Fig. 70 ) unguiform, curved dorsomedially. Tenth tergum ( Fig. 71 ) short and looks more trapezoidal, ventrally with one feebly developed, tufted tubercle at middle; posterolateral corner distinctly and acutely produced, tip slightly incised and densely setose. Tenth sternum ( Fig. 72 ) arched, anteriorly with one subtriangular process at middle; posterior incision indistinct; lateral lobes digitiform with distal half incurved. Female eighth sternum ( Figs. 73–74 ) strongly sclerotized and subtriangular in lateral view, with truncate posterior margin; ninth segment ( Fig. 73 ) laterally inflated in one pair of small oval sac-like lobes; ninth gonocoxite valvate and membranous with a digitiform process at tip; tenth tergum short, with posterior margin medially incised, leaving one subtriangular upper and one round lower lobe.

Distribution. China (Fujian).

Remarks. Protohermes fujianensis appears to be closely related to P. hunanensis and can be distinguished from the latter as follows: mandible yellow with distal half black, antenna black with scape and pedicel yellow, male tenth sternum with lateral lobes incurved in apical half. By contrast, P. hunanensis has the mandible and antenna entirely black and feebly incurved lateral lobes of the male tenth sternum.
