(Figs. 10, 46–49)
Diagnosis. This species is characterized by the forewing with numerous brownish spots, by the male tergum 9 with a dorsoprocessus, and the slenderly elongate male gonocoxite 10, which submedially bears a pointy lobe connecting to gonocoxite 9.
Description. Male. Body length 5.0–8.0 mm; forewing length 10.0–12.0 mm, hindwing length 8.0–10.0 mm.
Head brown, with pale yellow setose tubercles. Compound eyes blackish brown. Antenna with ca. 28 segments, yellowish brown, pedicel with brown annular stripes, flagellum unipectinate on most flagellomeres, longest branch nearly 3.0 times as long as relevant flagellomere.
Prothorax pale yellowish brown, pronotum brown, with anterior margin and posterolateral corners yellow, medially with a pair of ovoid markings; mesothorax pale yellowish brown, mesonotum dark brown on anterior and lateral margins; metanotum pale yellowish brown, slightly darker on lateral margins. Legs brown, femora blackish brown at tip. Wings hyaline, slightly smoky brown. Forewing ~2.1 times as long as wide, with numerous pale brown spots, distal spots slightly darker, an immaculate area present distal to median nygmata. Hindwing ~2.2 times as long as wide, much paler than forewing, with indistinct brownish spots.
Abdomen yellowish brown, pregenital segments dorsally dark brown. Tergum 9 in dorsal view with a shallowly arcuate anterior incision, a nearly U-shaped posterior incision and a long dorsoprocessus, leaving a pair of broad hemitergites, which are obtuse distally and densely haired. Sternum 9 obviously shorter than tergum 9, subtriangular. Ectoproct in dorsal view distinctly narrowed at middle, posteriorly with a transverse ridge, which is arcuately concaved, a pair of bifid projections and a trifurcate lobe present posterior to transverse ridge, posteroventrally with a pair of bifid unguiform projections. Gonocoxite 9 broadly inflated with blunt tip; gonocoxite 10 slenderly elongate, submedially with a pointy lobe connecting to gonocoxite 9; gonarcus slendely beam-shaped, laterally connecting to bases of gonocoxites 9. Hypandrium internum nearly trapezoidal, with lateral margins slightly arcuate.
Female. Unknown.
Materials examined. Holotype ♂, MYANMAR: Chin State, Natmataung Nat. Park, WNW Kanpetlet township [21°12′44′′N, 94°00′58′′E], 2340 m, 1.VI.2010, D. Zimmermann (NHMW). Paratypes 3♂, same data as holotype (NHMW); 5♂, MYANMAR: Chin State, Natmataung Nat. Park, WNW Kanpetlet township [21°13′24′′N, 93°58′50′′E], 2470 m, 31.V.2010, D. Zimmermann (NHMW).
Distribution. Myanmar (Chin).
Etymology. The new species is dedicated to Mag. Dominique Zimmermann (NHMW) who collected all the specimens.
Remarks. The late Prof. Bo Tjeder (1901–1992), one of the most famous neuropterologists had studied this new species (as Dilar burmanus Tjeder, which is, however, an unavailable name due to lack of formal description and differentiation) in his comparative morphological study on the genitalia of Neuropterida (Tjeder 1954). Based on the recently collected materials from northern Myanmar, we confirm that the specimens herein studied belong to the species (i.e. Dilar burmanus) studied by Tjeder (1954). However, it is obligatory to give this species a new name due to the unavailability of Dilar burmanus Tjeder based on the Article 13.1 of ICZN (1999). The new species also represents the first record of Dilaridae in Myanmar. The new species apparently belongs to the Dilar guangxiensis species-group (see Zhang et al. 2015) by the presence of dorsoprocessus on the male tergum 9 and the male gonocoxite 10 submedially with a pointed projection connecting to the male gonocoxite 9. It is distinguished from the other members of the D. guangxiensis group by the male ectoproct medially narrowed and ridged dorsad and also by the details of the male gonocoxites 9 and 10.
