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 : 149

Neoempheria brevispathulata sp. n.

[Japanese name: hera-nagamado-kinoko-bae] ( Figs. 2 d, 3d, 5, 12a, 12b)

Description. Body length: 4.5 mm. Wing length: 4.5 mm. Wing ( Fig. 3 d): vein sc-r ending basal 1/3 of anterior margin of cell r1. Vein Rs as long as distance between basal end of vein Rs and apical end of vein sc-r. Male: genitalia yellow in ground color, gonocoxal projection black, sternal projection and surrounding parts black, basal portion of aedeagus yellow. S9 ( Fig. 12 a: S9) narrow, less than 1/10 as wide as long, visible as seam between gonocoxites. Sternal projection ( Fig. 12 a: sp) of S9 short, with truncated, upward apex. Gonocoxite ( Fig. 12 a, b: gc) without gonocoxal lobe. Gonostylus ( Fig. 12 a: gs) slender, apical 1/4 less than 1.5 times as wide as base. Aedeagus ( Fig. 12 a, b) dilated at apical half, without projections. Sclerotized part of aedeagus ( Fig. 12 a: sa) tapered to apex, with slender, angled lateral extension. Female unknown.

Specimens examined. Holotype. Male. “ Philippines, Mindanao/ Sapamoro/ Curruan district/ 16.Dec.1961 / Noona Dan Exp. 61-62”, “Caught in/ Malaise/ traps”, green disk label, “Ne.7001” (ZMCU).

Etymology. The specific epithet is derived from Latin and refers to a short (brevis-) spatula-like (spathulatus) sternal projection of the sternite 9 ( Fig. 12 a).

Distribution. Philippine (Mindanao) ( Fig. 5 ).

Remarks. This species is distinguished from other species similar in general appearances by short, spatula-like sternal projection of the male sternite 9 ( Fig. 12 a).
