Diagnosis.
Dark stripes medially on lighter background extending entire length of scutum. Inner gonostylus posteriorly with wedge-shaped projection directed anteriorly. Tergite 9 at apex with three rounded notches, middle one usually deepest and widest.
Redescription.
Adult male (Fig. 1A, B View Figure 1 ). General color grey. Body length 14-17 mm, wing 14-17.5 mm.
Head. Light grey, sometimes bluish (Figs 1B View Figure 1 , 13A View Figure 13 ). Rostrum whitish dorsally, flanks rusty or brownish with whitish bristles; nasus distinct, with long, whitish yellow setae; palpus grey. Frons with rows of brown setae along inner edge of eye. Vertex with faint dark median line, posteriorly with dark grey striation, with group of small rusty setae arranged fan-like on either side of glabrous medial area. Genae rusty; wide dark median stripe ventrally on rostrum, continuing along gula midline. Pharyngeal foramen framed with long, rusty hair-like setae. Postgenae light grey.
Antenna (Fig. 1B View Figure 1 ) 13-segmented, if bent backwards just reaching wing base. Scape light brown or grey, depending on angle of rotation to light source, with slightly pronounced silvery pruinescence and brown horizontal striations. Pedicel yellow, sometimes brownish at base. Flagellomeres brownish, thickened at base, verticils subequal in length to corresponding flagellomeres.
Thorax (Fig. 1B View Figure 1 ). Grey or blue-grey. Pronotum with dark grey median stripe. Katepisternum, anepisternum and meron grey, glabrous. Scutum with four longitudinal wide brownish stripes on lighter background; medial stripes extending length of scutum. Scutal lobes, scutellum and mediotergite grey with light bristles in dark brown sockets.
Wings (Fig. 1A View Figure 1 ) greyish with a bluish tinge in transmitted light, stigma brown; narrow whitish area (lunule) extending to base of discal cell.
Halteres (Fig. 1A View Figure 1 ) with light brown or dark-yellow stem, lighter yellow at base, covered with short small pale setae; knob dark brown to black.
Legs with coxae light grey with long light hairs. Coxae may appear darker when specimen is rotated. Trochanters yellow. Femora yellow at base, rest of femora, tibiae, and tarsi dark brown.
Abdomen (Figs 1A View Figure 1 , 2A View Figure 2 ). Grey or dark grey; tergites with dark lateral stripe narrowly interrupted with whitish at posterior margins, lateral margins with wider whitish edge.
Terminalia (Figs 2 View Figure 2 , 14A, F View Figure 14 ). Hypopygium (Fig. 2B, C View Figure 2 ) not much thicker than rest of abdomen, brown with moderately dense grey pruinescence, with golden yellow hairs. Gonocoxite (Fig. 2C, G View Figure 2 ) with broad tooth ventrally. Tergite 9 (Figs 2C, E, F View Figure 2 ; 14A View Figure 14 ) transverse, lateral corner broadly rounded, at apex with three rounded notches, middle one usually deepest and widest, bounded laterally by two large dentate projections with blunt apices, clearly visible when viewed from above (Figs 2F View Figure 2 , 14A View Figure 14 ) ( Riedel 1920; Savchenko 1964). When viewed from behind, three pairs of very short projections are visible (Fig. 2E View Figure 2 ). Outer gonostylus (Figs 2G View Figure 2 , 14F View Figure 14 ) very small, wineglass shaped, elongated distally. Inner gonostylus posteriorly, with wedge-shaped projection (Figs 2G View Figure 2 , 14F View Figure 14 ). Paired appendage of sternite 8 (Fig. 2D View Figure 2 ) with base ~ 2 × as long as wide, with thin rigid yellow setae along edge, not obscuring gap in middle; long, glabrous red-brown spine arising from base, bent, and intersecting medially. Paired appendage of sternite 9 (Fig. 2K, L View Figure 2 ) with thick pubescent apex. Gonocoxal fragment (Fig. 2I View Figure 2 ) flattened at the base. Semen pump and aedeagus as in Figure 2J View Figure 2 .
Female. Body length 17-21.5 mm, wing 15.5-18 mm. Antennae with scape and pedicel brownish yellow. Legs stocky, black to brown, yellow at base, femora grey. Wings with noticeable bluish tint; whitish area (lunule) of wings barely reaching base of discal cell. Female terminalia (Fig. 12A-C View Figure 12 ) comparatively short. Tip of cercus upcurved, length of cercus ~ 0.8 mm. Hypogynial valve only slightly longer than width at base; length of hypogynial valve 0.2 mm. Sternite 9 and furca as in Figure 12A, C View Figure 12 .
Comparison with closely related species.
This species differs from other species of the Tipula caucasica group primarily by the presence of a large, anteriorly directed sharp wedge-shaped projection located posteriorly on the inner gonostylus.
Elevation.
Adults were collected at altitudes ranging from sea level (Black Sea coast at 35 m) to 2011 m (in Dagestan).
Flight period.
From end of April to the beginning of July.
Habitat.
Specimens were captured in diverse forest habitats (see above) predominantly in mesophytic moderately moist deciduous or mixed communities with Fagus orientalis , Taxus baccata , Carpinus orientalis , Quercus iberica , Populus tremula , Acer platanoides , etc., sometimes in communities near springs with Salix caprea .
Distribution.
Endemic to the Caucasus. It was recently noted for Russia (Dagestan) for the first time ( Lantsov 2020). Currently known from the West Caucasus (first record), East Caucasus and Transcaucasus.
Remarks.
According to Riedel (1920), a series of type specimens, four males, two females. “Mts’chet prope Tiflis [Georgia, Tbilisi], 6. 5. 1913 (Mus. Caucas. Ph. Zaitzev)" were deposited in the "Museum Caucasicum in Tiflis". In the author’s publication, neither the holotype nor the paratypes are indicated. Presumably, they are not indicated on the material itself. Because this material turned out to be inaccessible to the authors of this article - it is not yet known whether this material has survived at all - there was no opportunity to designate lectotype and paralectotypes.
