Protohermes uniformis Banks

( Figures 6 , 40–44 )

Protohermes uniformis Banks, 1931: 412 . Type locality: Malaysia (Sabah: Mt. Kinabalu).

Diagnosis. In appearance there are a pair of narrowly elongate black markings on posterolateral portions of vertex and a pair of rather narrow longitudinal black markings on pronotum. Genitalia of this species are characterized by the male ninth sternum with a pair of rather elongate and digitiform posterior lobes, the male ectoproct with broadly flattened apex, and the male tenth gonocoxite without posterodorsal inflation.

Description. Male. Body length 28 mm; forewing length 40 mm, hindwing length 33 mm.

Head ( Fig. 6 ) yellow, vertex posterolaterally with a pair of narrowly elongate black markings; post-ocular spine absent. Compound eyes brown; ocelli yellow, medially margined black, lateral ocelli close to median ocellus. Antenna with scape and pedicle yellow, flagellum damaged (described as dark colored in original description). Mouthparts yellow; mandible with distal half black, maxillary palpi brown.

Thorax ( Fig. 6 ) yellow; pronotum with a pair of narrow black longitudinal markings near lateral margins; meso- and metanota laterally pale brown. Thoracic pilosity white, much longer on meso- and meta thorax. Legs yellow, with short dense yellowish setae; tarsal claws pale reddish brown. Wings hyaline, with several whitish markings. Forewing slightly brownish, medially with several ovoid markings (currently faded and indistinct); pterostigmatic area pale yellow. Hindwing slightly brownish on distal half, immaculate. Veins yellowish brown to brown except for those in pale markings yellow. Rs 6-branched; MA bifurcate; 7 crossveins between R and Rs; anterior branch of MP 5-branched, posterior branch of MP 2-branched.

Abdomen brown. Ninth tergum ( Fig. 41 ) subtrapezoidal, with shallowly and arcuately incised anterior margin and truncate posterior margin. Ninth sternum ( Fig. 42 ) medially short, posterior margin deeply incised arcuate, forming a pair of elongate digitiform posterior lobes. Ninth gonostylus ( Fig. 42 ) slender unguiform, directed posteriad in lateral view, with tip slightly incurved. Ectoproct ( Figs. 41–43 ) band-like, ~3.5 times as long as ninth tergum, broadly flattened, slightly curved inward. Tenth gonocoxite ( Fig. 44 ) arched, posteromedially with a fringe of long setae; lateral lobes digitiform, straightly directed posteriad.

Female. Unknown.
