Protohermes stigmosus View in CoL sp. nov.
( Figs. 20 View FIGURES 16 – 23 , 123–127 View FIGURES 123 – 127 )
Diagnosis. Head without dark markings; pronotum with two pairs of blackish markings at anterolateral corner and three pairs of blackish markings at posterolateral corner; male ninth sternum has a wide U-shaped posterior incision, leaving two short acutely angled digitiform processes; tenth sternum with posterior incision strongly developed, leaving two large papillate processes with slender digitiformed tip, lateral lobes short and digitiform, proximally strongly inflated and narrowing toward tip.
Body length 25 mm; forewing length 38 mm, hindwing length 35 mm.
Head ( Fig. 123 View FIGURES 123 – 127 ) yellow with short and obtuse post-ocular spine; vertex without markings. Compound eyes brown; ocelli yellowish brown, darkly margined medially. Antennae black, with scapes and pedicel yellow. Mouthparts yellow; mandible with distal half black.
Prothorax ( Fig. 123 View FIGURES 123 – 127 ) yellow; pronotum with two pairs of blackish markings at anterolateral corner and three pairs of blackish markings at posterolateral corner. Meso- and metathorax pale yellowish brown. Thoracic pilosity yellow, much longer on meso- and metathorax. Legs yellow with dense yellowish short setae; distal half of fore tibiae and all fore tarsi black, middle and hind tarsi with 2nd–5th tarsomeres black; tarsal claws pale reddish brown. Forewings ( Fig. 20 View FIGURES 16 – 23 ) pale grayish brown except anal region entirely hyaline, with 1 subtriangular yellowish marking near base,1 broad and 1 narrow yellowish markings at middle, 1 round and 1 narrow yellowish markings on apical 1/3 and several extremely small yellowish markings on crossveins at apical portion; costal cellules with distinct grayish brown stripes. Hindwings entirely hyaline. Veins pale yellow except veins in dark regions of forewings and apical portion of hindwings pale brown. Rs 8-branched, last branch bifurcate; 9–12 crossveins between R1 and Rs; M1+2 4-branched, M3+4 2-branched; 1A 3-branched.
Abdomen pale yellowish brown with yellowish short setae. Male ninth tergum ( Fig. 124 View FIGURES 123 – 127 ) much wider posteriorly, with deep U-shaped anterior margin and shallowly incised posterior margin. Ninth sternum ( Fig. 125 View FIGURES 123 – 127 ) suboblong with central portion apparently inflated; posterior margin with wide U-shaped incision, forming two short, acutely angled digitiform processes. Ninth gonostylus ( Fig. 126 View FIGURES 123 – 127 ) unguiform and elongated, slightly curved dorsomedially. Tenth tergum ( Figs. 124–125 View FIGURES 123 – 127 ) short and subcylindrical, ventrally with one feebly developed tufted tubercle at posteromedial corner; tip slightly incised and densely setose. Tenth sternum ( Fig. 127 View FIGURES 123 – 127 ) arched, produced anteromedially; posterior incision strongly developed, forming two large median papillate processes, lateral lobes slender digitiform; lateral arms short and digitiform, proximally inflated and strongly narrowing toward tip.
Female unknown.
Type material. Holotype ɗ, CHINA: Yunnan, Xishuangbanna, 31.iii.2004, reared from larva, Liang Tang (SNU).
Etymology. The specific epithet ‘ stigmosus ’ refers to the complex pattern of the markings on the pronotum and the forewings of this species.
Distribution. China (Yunnan).
Remarks. This new species is distinguished from all the other members in the P. c o s t a l i s group based on the ten small dark, lateral spots on the pronotum, by the male ninth sternum with a wide, U-shaped posterior incision, and by the male tenth sternum with the abnormal posterior lobes. However, the more complicated wing patterns somewhat show the close affinity between P. s t i g m o s u s and P. triangulatus .
