description: Protohermes basimaculatus sp. nov.
(Figs. 9, 45–52)
Diagnosis. Head with two pairs of black markings; pronotum with two pairs of small, widely separated black markings; costal areas of forewing with basal 1–3 cellules marked brown; male tenth tergum laterally flattened; female ninth abdominal segment without sac-like lobes.
Body length 25–32 mm (male) and 35 mm (female); forewing length 37–40 mm (male) and 50 mm (female), hindwing length 34–35 mm (male) and 44 mm (female).
Head (Fig. 45) yellow, with blunt post-ocular spine; vertex with two pairs of black markings, lateral markings subtriangular, medial markings suboval. Occiput laterally with pair of black markings. Compound eyes greyish brown; ocelli yellow, darkly margined medially. Antennae dark, with scapes and pedicel yellow. Mouthparts yellow; mandible with distal half black.
Thorax yellow. Pronotum (Fig. 45) laterally with two pairs of small, widely separated black markings, posterior marking much broader than anterior marking, but sometimes separated into two narrow markings; posterolateral corner black. Meso- and metanota darker on lateral sides, medially pale. Thoracic pilosity yellow, much longer on meso- and metathorax. Legs yellow with dense yellowish short setae; 5th tarsus dark; tarsal claws reddish brown. Forewings (Fig. 9) slightly smoky brown, with 1 large yellowish marking at base, several fused yellowish markings and some small markings on crossveins between R1 and Rs at middle, and 1 round yellowish marking on apical 1/3; costal areas hyaline except for basal 1–3 cellules with distinct brown markings. Hindwings much paler than forewings, with 1 rather indistinct round yellowish marking on apical 1/3. Veins pale yellow but slightly darker toward apex; costal crossveins dark. Rs 9 to 10-branched, last branch bifurcate; 9–11 crossveins between R1 and Rs; M1+2 5-branched, M3+4 2-branched; 1A 3-branched.
Abdomen yellow with yellowish short setae. Male ninth tergum (Fig. 46) subquadrate, with arched anterior and slightly incised posterior margin. Ninth sternum (Fig. 47) broad with nearly straight lateral margin, posterior margin with wide V-shaped incision, forming two acutely angled triangular posterior processes; central portion apparently inflated. Ninth gonostylus (Fig. 48) unguiform and strongly curved dorsomedially. Tenth tergum (Figs. 46–48) short subcylindrical, laterally flattened, ventrally with one tuft at posteromedial corner; tip slightly incised and densely setose. Tenth sternum (Fig. 50) arched, anteriorly slightly elevated at middle; posterior margin medially produced with one small incision at tip; lateral lobes long digitiform. Female eighth sternum (Figs. 51–52) strongly sclerotized, subtriangular in lateral view, posterior margin truncate; ninth segment (Fig. 51) without sac-like lobes; ninth gonocoxite valvate and membranous with one digitiform process at tip; tenth tergum short, with posterior margin medially incised, leaving one short digitiform upper and one semicircular lower lobe.
Type materials. Holotype ɗ, CHINA: Yunnan, Baoshan, Baihualing, 1500 m, 22.V.2006, Xingyue Liu (CAU). Paratypes: 2 ɗ, CHINA: same data as holotype (CAU); 2 ɗ Ψ, CHINA: Yunnan, Baoshan, Baihualing, 1500 m, 23.V.2006, Xingyue Liu (CAU).
Distribution. China (Yunnan).
Etymology. The specific epithet ‘ basimaculatus ’ refers to the feature of the forewing with only the basal 1–3 costal cellules marked brown in the new species.
Remarks. The new species is distinguished from the other species of the P. costalis group by the forewing only with the basal 1–3 costal cellules marked brown, the laterally flattened male tenth tergum, and the female ninth abdominal segment without sac-like lobes.
