Protohermes pennyi sp. nov.

( Figures 4 , 26–32 )

Etymology

The new species is dedicated to Dr Norm D. Penny, who made great contributions to the systematics of Megaloptera from South Africa and the New World, and helped the authors in many ways.

Diagnosis

Head with a pair of nearly F-shaped black markings; male tenth sternum with a ventromedial process and digitiform lateral lobes.

Type materials

Holotype: male, NEPAL, 1964 ( NSM) . Paratype: one female, NEPAL, Dunche , 28 ° 069N, 85 ° 199E, 30 May 1968 ( NSM) .

Male

Body length 22 mm; forewing length 37 mm, hindwing length 33 mm.

Head. Yellow, vertex with a pair of nearly F-shaped black markings on lateral margins; post-ocular spine short and blunt. Compound eyes grayish brown; ocelli pale yellow, medially margined black. Antennae pale brown, with scape and pedicel yellow. Mouthparts yellowish brown; mandibles with apices reddish brown.

Thorax. Yellow; pronotum with a pair of black vittae on lateral margins, nearly broken at middle, anterior portions of vittae slightly curved laterally, posterior portions of vittae usually longitudinally separated. Thoracic pilosity pale yellow, much longer on meso- and metathorax. Legs yellow with yellowish short dense setae; tarsal claws reddish. Wings hyaline, immaculate, slightly brownish; veins pale yellowish brown, basal anal veins blackish brown. Rs six- to seven-branched, last branch bifurcate; 9–11 crossveins between R 1 and Rs; M 1+2 four- to five-branched, M 3+4 two-branched; 1A three-branched.

Abdomen. Brown with yellow venter. Ninth tergum ( Figure 27 ) broad, nearly hexagonal, with an arcuate anterior incision. Ninth sternum ( Figure 28 ) broad, subquadrate, medially with a shallow longitudinal incision; posterior margin shallowly incised, medially with a small V-shaped incision, posterolateral processes obtuse and rather small. Ninth gonostylus unguiform, slightly curved inward. Tenth tergum ( Figures 27–28 ) flattened, much shorter than ninth tergum, directed posterolaterally, subquadrate with posterior margin rounded. Tenth sternum ( Figures 29–30 ) extremely small; dorsomedial process moderately developed, medially with a small incision; posterior margin with a ventromedial process; lateral lobes digitiform with pointed tip.

Female

Body length 41 mm; forewing length 51 mm, hindwing length 45 mm.

Abdomen. Eighth sternum ( Figures 31–32 ) subtrapezoidal in lateral view; in ventral view anterior margin moderately incised, posterior margin roundly produced. Ninth gonocoxite broad, posterior portion rounded and slightly incised ventrad, with a small digitiform gonostylus at tip. Tenth tergum short, with posterior margin medially incised, leaving thick, rounded, dorsal and ventral lobes; ventral lobe slightly longer than dorsal lobe.

Distribution

Nepal (Dunche).

Remarks

The new species is the most distinguished member of the P. parcus group by the Fshaped markings on the vertex and the presence of the ventromedial process of the male tenth sternum.
