Protohermes gutianensis Yang & Yang, 1995 b. Insects and macrofungi of Gutianshan, Zhejiang, p. 129. Type locality: Zhejiang (Kaihua).

Diagnosis. Head with black markings from anterior edge of compound eyes through to occiput and a narrow blackish vittae medially on vertex; pronotum with one pair of blackish vittae on lateral margins; wings pale smoky brown with several indistinct yellowish spots except for apical regions without spots; male ninth sternum with suboblong posterior incision.

Body length 28–31 mm (male) and 40–45 mm (female); forewing length 38–48 mm (male) and 48–52 mm (female), hindwing length 35–41 mm (male) and 43–47 mm (female).

Head ( Fig. 75 ) yellowish brown, without post-ocular spine, dorsally black near post-ocular margins, sometimes entirely black near lateral margins; vertex also with one narrow blackish vittae medially. Compound eyes brown; ocelli yellow, darkly margined medially. Antennae black with scapes and pedicel brown. Mouthparts yellow; mandible with distal half black.

Prothorax ( Fig. 75 ) yellowish brown; pronotum with one pair of blackish vittae laterally. Meso- and metathorax yellow, each dorsally with one pair of brownish spots on anterolateral corners. Thoracic pilosity yellow, much longer on meso- and metathorax. Legs black with dense, pale yellow, short setae; coxae and trochanters pale yellow; femora brown; tarsal claws reddish brown. Forewings ( Fig. 13 ) slightly smoky brown, with 1 small yellowish marking at base, 2–4 yellowish markings along cubital veins at middle; costal cellules with distinct brownish stripes. Hindwings much paler than forewings with hyaline basal half. Veins pale brown, except pale yellow veins in yellowish markings and base of hindwings. Rs 9–10 branched, last branch mostly trifurcate; 9 to 10-crossveins between R1 and Rs; M1+2 5 to 7-branched, M3+4 3 to 4-branched; 1A 3-branched.

Abdomen brown with short, yellow setae. Male ninth tergum ( Fig. 76 ) subquadrate, with trapezoidal anterior margin and shallowly incised posterior margin. Ninth sternum ( Fig. 77 ) broad with arched lateral margin; posterior margin with deep suboblong incision, forming two broad acute-angled subtriangular processes; central portion inflated. Ninth gonostylus ( Fig. 78 ) unguiform and slightly curved dorsomedially. Tenth tergum ( Figs. 76–77 ) short and subcylindrical, ventrally with one well developed tufted tubercle at posteromedial corner; posterolateral corner distinctly and acutely produced; tip slightly incised and densely setose. Tenth sternum ( Fig. 79 ) arched, anteriorly with one trapezoidal process at middle and posteriorly with one small triangular incision; lateral lobes slender digitiform and slightly incurved. Female eighth sternum ( Figs. 80–81 ) strongly sclerotized, subtrapezoidal in lateral view, with truncate posterior margin; ninth segment ( Fig. 80 ) 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 long digitiform upper and one short round lower lobe.

Remarks. Protohermes gutianensis appears to be closely related to P. acutatus by the absence of the apical round markings of both wings, but it can be easily separated from P. acutatus by having the head with a pair of slender blackish vittae and the male ninth sternum with deep suboblong apical incision, both of which are unique in the P. c o s t a l i s group.
