Protohermes ohli sp. nov.

( Figs. 4 , 26–30 )

Diagnosis. This species is characterized by the yellow body coloration, the immaculate head, pronotum with two pairs of small and widely separated black markings, and the male ninth sternum with nearly truncate posterior margin and a pair of short subtriangular posterolateral lobes.

Description. Male. Body length 28–31 mm; forewing length 34–37 mm, hindwing length 29–34 mm.

Head ( Fig. 26 ) yellow, immaculate; postocular spine almost absent. Compound eyes blackish brown; ocelli yellow, medially margined black, lateral ocelli slightly separated from median ocellus with distance between them shorter than distance between antennal bases. Antennae blackish brown except for scape and pedicel yellow. Mouthparts yellow; mandible with distal half blackish brown.

Prothorax ( Fig. 26 ) yellow; pronotum with two pairs of short and narrow black markings near lateral margins. Meso- and metathorax pale yellow, slightly grayish laterally, with a pair of small brownish spots anteriorly on mesonotum. Thoracic pilosity yellow, much longer on meso- and metathorax. Legs pale yellow with short dense yellowish setae; forelegs with apices of tibiae and tarsi slightly grayish; tarsal claws reddish brown. Wings ( Fig. 4 ) almost hyaline, with several white markings. Forewing pale grayish, with a few white markings along Cu, which are somewhat connected with each other, distally with an indistinct round marking. Hindwing immaculate. Veins yellow, except for costal crossveins on proximal ⅔ of costal area blackish brown. Rs 8 to 9-branched; MA bifurcate; anterior branch of MP 4-branched, posterior branch of MP 2-branched; 7–9 crossveins between R and Rs.

Abdomen yellow. Ninth tergum ( Fig. 27 ) subquadrate, with arcuately incised anterior and truncate posterior margins. Ninth sternum ( Fig. 28 ) subtrapezoidal, much shorter than ninth tergum, medially strongly inflated, posterior margin nearly truncate, posterolateral lobe short and subtriangular with obtuse apex. Ninth gonostylus ( Fig. 29 ) unguiform and feebly curved dorsomedially. Ectoproct ( Figs. 28–29 ) bifurcated proximally into dorsal and ventral lobes; dorsal lobe band-like, densely setose, ~2.0X as long as ninth tergum, bluntly tapering and slightly curved ventromedially; ventral lobe subtriangular, ~0.3X as long as dorsal lobe, produced medially and bluntly tapering. Tenth gonocoxite ( Fig. 30 ) narrowly arched, dorsomedial process strongly developed, ventromedial process paired and feebly prominent; lateral lobes digitiform, slightly curved medially, and densely setose on ventral surface.

Female. Unknown.

Type materials. Holotype ♂, “ MYANMAR: Chin, W[estern] Hakha, 2260 m, 22°41'N, 93°35'E, 23– 24.V.2001, LF, leg. S. Naumann” (ZMHU). Paratype 1♂, “sent to B[ritish].M[useum]. from India, no data, some years ago, K.G.B., 17.XI. [19]20” (BMNH).

Distribution. India; Myanmar ( Chin).

Etymology. This new species is dedicated to Dr. Michael Ohl (Berlin) who kindly hosted the first author in MFN allowing the examination of the Megaloptera holdings.

Remarks. The new species appears to be closely related to P. subnubilus in having similar yellow body coloration and prothoracic marking pattern. However, P. ohli sp. nov. can be distinguished from P. subnubilus by the immaculate head and the male ninth sternum with short subtriangular posterolateral lobes. In P. subnubilus , the head possesses black markings on vertex and the male ninth sternum is distinctly incised posteriorly, leaving a pair of digitiform posterolateral lobes.
