Borneomymar madagascar : Huber, 2002: 48 (original description); Engel et al. 2013: 2 (comparison with a fossil species).

Diagnosis.

This species differs from, B. discus Huber, the only other extant species now included in the genus, as follows: radicle about as long as wide, scape 2.84 × as long as wide (in B. discus radicle much longer than wide, scape 5.86 × as long as wide); fore wing uniformly hyaline (Fig. 180 ) (in B. discus fore wing with distinct brown areas); gaster in lateral view about as 0.5 × as high as long (almost circular in B. discus ).

Description.

Female. Body length 922-998 (n = 4, critical point dried specimens, measured to apex of hypopygium), ovipositor length ≈ 2022-2330 (not completely straight so probably slightly longer). Head (Fig. 184 ) width 266. Antenna measurements (n = 1), length/width (ratio): scape 101/36 (2.84), pedicel 56/35 (1.59), fl1 68/20 (3.35), fl2 81/30 (2.73), fl3 82/29 (2.81), fl4 86/30 (2.85), fl5 79/32 (2.43), fl6 76/34 (2.25), fl7 72/32 (2.27), fl8 74/34 (2.20), clava 176/52 (3.40); fl2-fl8 each apparently with 3 mps, clava with 12 mps (Fig. 179 ; hypopygium extending distinctly beyond posterior apex of gaster. Male. Body length ≈ 1315 (excluding gt7, removed to extract genitalia). Head (Fig. 184 ) width 262. Antenna measurements (n= 1, slide mounted), length/width [scape-fl4 are vertical so width cannot be measured]: scape 104/ -, pedicel 56/ -, fl1 106/ -, fl2108/ -, fl3 106/ -, fl4 108/ -, fl5 111/≈ 35, fl6 101/38, fl7 92/42, fl8 96/41, fl9 94/41, fl10 91/39, fl11 88/35; total flagellar length 1102; fl6 length/width 2.66, with 9? mps.
