description: Epicnemis linguiformis sp. n.
Diagnosis. Frons convergent upward; pulpus with 6 setae apically and without hairs ventrally; vein costal index about 0.6, vein M 1 curved rewards; longitudinal hair palisade of mid tibia extending to 2/3 of its length; anal tube as long as upside of epandrium; left side of epandrium with a spherical, tongue-like process; right side of epandrium with a long finger-like process; penis complex long.
Description. Male. Frons (Fig. 3) brown, higher than broad, convergent upward, with 75–85 hairs. Supra-antennal setae close together, as long as other frontal setae. Lower interfrontal setae about mid way between supra-antennals and lower fronto-orbital setae, but latter higher on frons. Upper interfrontal setae further apart than lower interfrontal setae. Ocellar triangle with many hairs, the ocelli globular, raised. Outer vertical setae short. Flagellomere 1 globular, but slightly pointed apically, and light brown. Arista pre-apical in position. Palpus as broad as diameter of Flagellomere 1, light yellow with six small setae at apex. Proboscis small, with small labrum.
Thorax (Fig. 1) yellow brown with darker rear margins of scutum and scutellum. Anepisternum with about 25 hairs on upper half. Notopleuron with 2 setae. Scutellum with four equally developed setae.
Legs (Figs. 4–6) dusky yellow. Fore tibia with a row of 7–8 short dorsal setae. Mid tibia with a longitudinal hair palisade extending to 2/3 of its length and with a set of transverse antero-dorsal hair combs below its tip. A short anterodorsal seta and a postero-dorsal seta in basal quarter; another antero-dorsal seta in half length. Hind tibia with a complete longitudinal hair palisade and a row of 4 short antero-dorsal setae.
Wing (Fig. 2) length 2.96–3.05 mm. Costal index 0.58–0.60. Costal ratios 2.18–2.19: 1. Costal cilia minute, 0.018 – 0.020 mm long, the posterior row incomplete, and not reaching end of costal section 1. Vein Rs with 1 small hairs at its base. Vein Sc obscure, except at extreme base. Vein M 1 concaved and curved backward at apex. Vein M 2 a little S-formed, and curved forward apically. All veins brown, but vein A1 pale. Membrane tinged light brown. With two well developed axillary setae. Halter with brown knob and paler stem.
Abdominal tergites (Fig. 1) mainly yellow brown, with dark brown sides. Rear of tergite VI pale yellow. All tergites covered with robust short hairs, which are a little longer on tergite VI. Venter dusky yellow, almost bare apart from some short robust hairs adjacent to tergite VI.
Terminalia (Figs. 7–8, 9–10) yellow brown, with greyish yellow anal tube. The penis complex is generally brown to dark brown. Left side of epandrium rounded, with 8–10 hairs along apical margin and with a tongue-like process ventrally, which covered with minute agnails. A deep crack at the base of the process. Right side of epandrium with three processes: the upper one rounded apically, with about 7–8 seta-like hairs; the mid one triangular, with a long seta on its base; the lower one long, finger-like, with a lot of hairs apically. Penis complex long and extending downward. Anal tube relative long, as long as dorsal length of epandrium.
Female: unknown.
Etymology. The ethnic name refers to the tongue-like process of left side of epandrium.
Materials examined. Holotype ♂, China: Jiangxi, Jian (26°54′01.56″N, 114°21′34.71″E; 174m), 24 May 2009, Tao Li; papatypes. 9 ♂, same data as holoty; 1 ♂, same locality and collector, 10 May 2009; 3 ♂, same locality and collector, 8 Jun 2009; 2 ♂, China: Jiangxi, Quannan, Mt. Jiulian (24°40′35.83″N, 114°35′03.96″E; 545m), 12 Jun 2011, Tao Li.
Remarks. The new species is different from all other species of the genus by its tongue-like process of the left side on epandrium and a long finger-like hairy process of the right side of epandrium. Comparing to other described species of the genus the new species is similar to E. namkyensis Mostovski, 2000, in terms of long anal tube and penis complex, but it directly distinguished by the characters of epandrium. In addition, it is also different from latter by palpus with 6 apical setae and without hairs ventrally, longitudinal hair palisade of mid tibia extending 2/3 of its length and with a longer costa.
