Sueyoshi, Masahiro, 2014, Taxonomy of fungus gnats allied to Neoempheria ferruginea (Brunetti, 1912) (Diptera: Mycetophilidae), with descriptions of 11 new species from Japan and adjacent areas, Zootaxa 3790 (1), pp. 139-164 : 158

Neoempheria latisternata sp. n.

[Japanese name: harabiro-nagamado-kinoko-bae] ( Figs. 2 j, 3j, 5, 16c, 16d)

Description. Body length: 4.4 mm. Wing length: 5.6 mm. Wing ( Fig. 3 j): vein sc-r ending basal 7/16 of anterior margin of cell r1. Vein Rs shorter than distance between basal end of vein Rs and apical end of vein sc-r. Male: genitalia yellow in ground color, with distinct black marks on S9 and surrounding parts, basal portion of aedeagus black. S9 ( Fig. 16 c: S9) broad, 1/2 as wide as long, without sternal projections. Gonocoxite ( Fig. 16 c, d: gc) without gonocoxal lobe. Gonostylus ( Fig. 16 c: gs) short, apical half 2 times as wide as base. Aedeagus ( Fig. 16 c, d) dilated at apical half, with pair of ventral projections ( Fig. 16 c, d: vp). Sclerotized part of aedeagus ( Fig. 16 c: sa) with 2 pairs of extensions, ventral pair supporting projection, dorsal pair extending to dorsolateral portion of aedeagus. Female unknown.

Specimens examined. Holotype. Male. “[E. NEPAL]/ Basantapur (2300m)/ 27°06′N, 87°23′E- --/ 27°08′N, 87°26′E ”, “ June 14, 1972 / H. Makihara leg./ Kyushu Univ. Col.”, “Ne.1196” (BLKU).

Etymology. The specific epithet is derived from Latin and refers to the sternite 9 (sterna) being broad (lati-) ( Fig. 16 c).

Distribution. Nepal ( Fig. 5 ).

Remarks. This species is distinguished from other species similar in general appearances by the male sternite 9, which is half as wide as long ( Fig. 16 c).
