Description. Male. Head. Face paler brown than antenna, maxillary palpus pale brown. Eye bridge 2–3 facets wide. Face with 15–30 setae. Clypeus with 2–5 setae. Maxillary palpus with 3 segments, 1 st segment as long as 3 rd segment, 2 nd segment shortest; 1 st segment with 5 setae, with small dorsal pit with sensilla; surface of antennal flagellomeres smooth, body of 4 th antennal flagellomere 2.35–2.50x as long as wide, neck shorter than wide, longest setae longer than width of flagellomere. Thorax. Brown; setae pale.Anterior pronotum with 4–6 setae. Proepisternum with 6–11 setae. Scutellum with 2 moderate and some short and fine setae. Wing. Hyaline. Length 1.4 mm. Width/ length 0.45.Anal lobe rather small. Veins distinct, except stM. c/w 0.55–0.70. R1/R 0.65–85. stM shorter than fork of M. bM shorter, longer or as long as r-m, stCuA shortest. bM and r-m non-setose. Halter yellow. Legs. Yellow; setae pale. Fore tibial organ forming large patch of many setae in demarcated depression. Fore tibial spur as long as apical width of tibia. Abdomen. Pale brown; setae pale, short and fine. Hypopygium (Fig. 7A). Brown, like abdomen. Intergonocoxal area moderate, with short setose lobe. Gonocoxa narrow, much longer than gonostylus, with dense and short setosity. Gonostylus (Fig. 9A) very narrow, evenly narrowed towards apex, strongly impressed medially; densely setose apically, with long apical tooth; with 2 subapical and 3 medial megasetae in medial impression, 2 of medial megasetae close to subapical megasetae, 1 longer and stronger one near middle of gonostylus, megasetae straight or very slightly curved, all shorter than apical tooth; with well-differentiated long whip-lash seta in middle of gonostylus. Tegmen broadly conical, membraneous apically, weakly sclerotized laterally, with small area of aedeagal teeth. Aedeagal apodeme rather long.
BIN. Unknown.
Discussion. With its slender gonostylus, Lycoriella longa sp. n. possesses the typical gonostylar structure of the genus, but differs in having its gonostylus distinctly impressed dorsomedially and in having a single conspicuous medial megaseta in the middle of the gonostylus, well separated from the other megasetae.
Etymology. The name is a Latin adjective, longa (long), referring to the long gonostylus, the long medial megaseta and the long antenna.
