Diagnosis. The new species differs from T. (E.) nigrimana (Loew, 1866) and Timia (Empyelocera) altaica Galinskaya sp. nov. by frons, scutum and pleura with long (c. 0.6–0.8 times as long as setae) hairs; the frontal orbit with whitish microtrichose triangular spot at its anterior margin.
Description of the holotype. Male: Head. Frons from dark brown (posteriorly) to pale brown (anteriorly) with dents and bumps. Frons shining, with three microtrichose areas (a narrow spindle-like stripe at the middle of frons and two rather broad bands with rows of confluent shining spots along eye margins). Vertical plate long setose (longest setae 0.6–0.8 times as long as antenna). The orbit of the frons with whitish microtrichose triangular spot at the anterior margin. Ocellar triangle shining black. Lateral parts of vertex with black marks. Median occipital sclerite black, brownish close to ocellar triangle, with silver-white microtrichosity close to vertex. Lateral occipital sclerite black, with silver-white microtrichosity close to eye margin. Postgena pale yellow anteriorly, black posteriorly. Parafacialium yellow ventrally, brown dorsally, as wide as antennal groove, 1.4 times as wide as flagellomere 1. Gena yellow, slightly darkened along the lower edge and with a series of short black setulae, without large spines. Gena 0.7 times as high as eye. Eye 1.1 times as high as wide. Lunula yellow. Face yellow, with slightly darkened band along the lower edge; face with black vertical bands below antenna. Scape and pedicel black. Flagellomere 1 black, dark brown laterally, matted. Arista dark brown. Antennal groove black, with thin silver-white microtrichosity. Proboscis dark brown. Palpus dark brown.
Setae. 6 pairs of small orbital setae (anterior orbital seta not longer than the other ones), 1 pair of ocellar setae, 1 pair of postocellar setae, 1 pair of long medial vertical setae, 7 pairs of postocular setae, 1 pair of short paravertical setae and 1 pair of long lateral vertical setae. 10 pairs of genal setulae, 12 pairs of postgenal setulae, 1 pair of long genal setae.
Thorax. Black. Mesonotum silvery white microtrichose, with rows of confluent shining spots around setae; scutum with thin longitudinal shining stripes. Postpronotum with silver-white microtrichosity. Scutellum black, flattened dorsally; dorsally silvery white microtrichose, with rows of confluent shining spots; with short black setulae over its upper surface. Mediotergite black, silvery white microtrichose. Pleura black, long setose (longest setae 0.6–0.8 times as long as taxonomically significant setae).
Setae. 1 pair of postpronotal setae, 2 pairs of notopleural setae, 1 pair of supra-alar setae, 1 pair of dorsocentral setae, 1 pair of postalar setae, 1 pair of intra-alar setae; 2 pairs of scutellar setae; 1 pair of anepisternal setae, 1 pair of katepisternal setae; also anepisternum and katepisternum covered with short black setulae.
Legs. Fore leg brown with basal 2/3 of femur yellow. Mid leg yellow with tarsus (except first tarsomere) darkened to brown. Hind leg brown with femur and basal 1/2 of tibia yellow.
Wings. Hyaline. Posteroapical extension of cell bcu long, 4.2 times as long as transverse section of vein Cu2. Halter yellow.
Abdomen black, evenly thin black setulose.
Male genitalia. Surstylus with mesoventrally curved anteroventral lobe and with short posteromedial lobe covered with strong setae on its ventral side. Cerci fused, elongated and thinned apically, covered with rare thin setulae.
Remarks. Variability was observed in size.
Body length 5.5–5.8 mm. Wing length 5.2–5.4 mm.
Female: similar to male.
Body length 7.0– 7.4 mm. Wing length 5.5–5.9 mm.
Etymology. The species name is based on the Russian “мохнатый”, furry; because of long setulae on vertical plates and pleura.
Distribution. Eastern Pamir (Tajikistan).
