Abstract A new species of Triphleba Rondani is described and illustrated from Kyrgyzstan. We provide data on the sampling site, photos of the new species and brief differential diagnosis to separate from related species. Additionally, another ten species from Kyrgyzstan are reported and shortly discussed. All they are recorded for the first time for Kyrgyzstan and respectively Central Asia. Key words: Diptera, Phoridae, Triphleba, new species, Kyrgyzstan, new records. Introduction Genus Triphleba Rondani, 1856 includes about 66 species in the Palaearctic Region. They are basically covered by Schmitz (1943, 1949, 1955), supplemented and with additions by Delage & Lauraire (1970), Gotô & Takeno (1983), Disney (1983, 1987, 1994, 2011), Michailovskaya (1986, 1999), Gori (1999, 2000), Liu (2001), Disney & Chapman (2001), Disney & Michailovskaya (2002), Mostovski & Disney (2002), Disney & Brenner (2003), Carles-Tolrá & García-Romera (2011), Liu & Liu (2012), Disney & Winqvist (2018), Disney & Haarto (2019). In this paper, a new species, Triphleba simovi sp. nov., from Middle Asia is described and illustrated. Material and methods The scuttle flies were collected by Nikolay Simov fixed in 75% ethanol. The photographs were made using a Carl Zeiss Jena Amplival microscope and Carl Zeiss Stemi 2000 stereomicroscope with a digital camera (Canon EOS 2000D). The type material is stored in the author’s collection in the National Museum of Natural History, Sofia (NMNHS).

In the keys to Palaearctic species (Schmitz, 1943) males runs to couplet 20, lead 1 to T. dudai (Schmitz, 1918) on page 139 and females to couplet 19 at the same page. The males clearly differ on the hypopygium (Figs 3-4) and the females – on the sternite 7 (Fig. 7), plus in both sexesof the new species costa thickens apically (C2 and C3).

Frons brown, little broader than long (1.2:1), with about sixteen hairs and dense, very fine, microsetae. Supra-antennals less than half length of antials. Anterolateral bristles a little higher on frons than antials. Pre-ocellars slightly lower on frons than mediolaterals and all four bristles about equidistant. Antenna: postpedicel brown, rounded; arista subapical, short pubescent. Palps brown, with about 5-6 bristles, apical one longer and stronger. Thorax brown. 3 notopleurals (Fig. 1). Scutellum with a single pair of long bristles only. Wing brownish, veins brown (Fig. 2). Costa thickens apically (sections 2 and 3 of costa - C2 and C3). Sc reaches vein 1. Vein 2 complete. One hair at base of R4+5. Anal vein short, not reaching wing margin. A single axillary bristle. Haltere brown.

Legs brown, fore tibia with 1 short anterodorsal proximal bristle, mid tibia with 2 proximal bristles (anterodorsal one twice long than posterodorsal), hind tibia with 1 anterodorsal proximal bristle. Abdomen brown, tergites with short hairs. Venter brownish. Hypopygium (Figs 3-4): left epandrial process (Fig. 3) large, elongated, pointed apically, haired with 3 stronger hairs near the base; right epandrial process (Fig. 4) about twice shorter, haired. Body length 1.5- 1.8 mm. Female. Head similar to male, but the labrum is slightly larger (Fig. 5). Thorax as male (Fig. 6). Abdominal tergites brown with short hairs. Venter paler brown with hairs below on segments 3-6 near the rear margin and on flanks, especially on segments 4-5. Sternite 7 as Fig. 7. Legs similar to male. Wing as Fig. 8, similar to male. Haltere brown. Costal index = 0.46, costal ratios = 1.5:0.8:1. Body length 3.0-3.2 mm. Figures 5-8. Triphleba simovi sp. n. female: 5: general view; 6: head and thorax; 7: sternite 7; 8: wing.

All the material deposited in the author’s collection in the National Museum of Natural History, Sofia. 36 LANGOUROV Etymology. Named after the Bulgarian entomologist Dr Nikolay Simov who collected the material. Habitat. The type specimens were collected from high-mountain grass societies (above 3000 m: Figs 9-10). Distribution. Known only from its type locality, the Tien Shan Mts, Kakshaal-Too Range, At-Bashi District, Kyrgyz Republic. It is likely that this species can also be found in surrounding areas of the mountain. Figures 9-10.
