Protohermes lii sp. nov.

( Figs. 15 , 90–94 )

Diagnosis. Head without dark markings; pronotum with two small blackish bivittate on lateral sides; male ninth sternum with wide, shallow posterior incision; male tenth tergum with feebly developed ventral tufted tubercle.

Body length 23–25 mm (male); forewing length 37–39 mm (male), hindwing length 34–35 mm (male).

Head ( Fig. 90 ) yellow, without post-ocular spine; vertex without markings. Compound eyes pale brown; ocelli yellow, darkly margined medially. Antennae dark, scapes and pedicel yellow. Mouthparts yellow; mandible distally dark.

Prothorax yellow; pronotum ( Fig. 90 ) with two pairs of widely separated small blackish markings on each side. Meso- and metathorax pale yellow. Thoracic pilosity yellow, much longer on meso- and metathorax. Legs yellow with dense yellowish short setae; wide apices of fore and mid tibiae and 2nd–5th tarsi dark; tarsal claws reddish brown. Forewings ( Fig. 15 ) pale smoky brown, with 1 large yellowish marking at base, 3 mostly connected large and 5–7 small yellowish markings on crossveins between R1 and Rs at middle, and 1 round yellowish marking on apical 1/3; costal cellules with distinct brown stripes. Hindwings much paler than forewings, respectively with 1 round yellowish marking at middle and apical 1/3. Veins brown except veins in yellowish markings and basal half of hindwings pale yellow. Rs 9 to 10-branched, last branch bifurcate; 10–13 crossveins between R1 and Rs; M1+2 6 to 7-branched, M3+4 3-branched; 1A 3-branched.

Abdomen yellow with short, yellow setae. Male ninth tergum ( Fig. 91 ) subtrapezoidal, with arched anterior margin and sightly incised posterior margin. Ninth sternum ( Fig. 92 ) broad with lateral margin slightly curved near anterior 1/4, posterior margin with broad, shallow incision, forming two acute-angled posterior processes; central portion inflated. Ninth gonostylus ( Fig. 93 ) unguiform and slightly curved dorsomedially. Tenth tergum ( Figs. 91–92 ) short, subcylindrical, ventrally with one feebly developed tufted tubercle near posteromedial corner; posterolateral corner slightly and acutely produced; tip slightly incised and densely setose. Tenth sternum ( Fig. 94 ) slightly arched, anteriorly slightly elevated at middle, posterior margin with extremely small V-shaped median incision and a pair of small denticles; lateral lobes digitiform, with apex strongly narrowed and incurved.

Female unknown.

Type material. Holotype ɗ, CHINA: Guangxi, Fangcheng, Dongzhong, 360–700 m, 9.IV.2002, Aimin Shi (HBU). Paratypes ɗ, CHINA: same data as holotype (HBU); ɗ, CHINA: Guangxi, Shangsi, Pinglongshan, 350–500 m, 6.IV.2002, Aimin Shi (HBU); ɗ, CHINA: Guangxi, Shiwandashan, VIII.2002, Ding Yang ( CAU).

Etymology. The specific epithet ‘ lii ’ refers to Prof. Fasheng Li, who is a famous entomologist on Psocoptera and Hemiptera at the China Agricultural University. We thank him for his kind help with our studies to collect numerous megalopteran specimens during the past thirty years.

Distributions. China (Guangxi).

Remarks. The new species somewhat resembles P. basiflavus , but can be easily separated by the smaller body size, the widely separated, small prothoracic black markings, the feebly developed ventral tufted turbercle of the male tenth tergum, and the male tenth sternum with the posterior margin bearing a pair of small denticles. In P. basiflavus , the body size and the prothoracic markings are much larger, the ventral tufted turbercle of the male tenth tergum is well developed, and the male tenth sternum posteriorly bears a pair of distinctly produced processes.
