M a t e r i a l. Type. Holotype ♀, [ Ukraine, Kyiv Region], Lyutizh, soil with grass under a rotting pine trunk, 09.23 1968, specimen #3552 (177), 50°41'00.0" N 30°23'50.0" E ( Pirianyk ) ( SIZK).

Non-type. 31 ♀, 1 Ơ (32 specimens): Ukraine, Crimea (main range of mountains; Karadag), Donetsk, Kyiv, Poltava Regions .

R e d e s c r i p t i o n. F e m a l e. Dorsal shield ( fig. 5 , 1 ) well sclerotized, ovoid, with slight lateral emarginations, smooth, oblique linear striation along shield margins; solenostomes 7 pairs (it, iv, id, isc, il, is, ic). Dorsal setae pointed, contrasting in length from elongated to miniature. The longest are AL4, PM3, and PM4, of which PM3 and PM4 are serrated. Seta PL1 about twice as long as both PL2 and PL3. Ventrianal shield slightly wider than genital shield, pentagonal with nearly parallel lateral margins, anterior margin slightly convex; anal pores clearly visible, round, close together ( fig. 5 , 2 ). Anterior metapodal scutum narrow, linear; the posterior one fusiform ( fig. 5 , 3 ). The posterior part of the peritremal shield smoothly curved, beak-shaped at the end, with a pore on tip ( fig. 5 , 4 ). Chelicera with 3 teeth on Df, and with 1 on Dm ( fig. 5, 5 ). The funnel of the spermatheca long, capable of bending in the narrowed middle part, with a wide bell at the sacculus; the atrium is immersed in the base of the funnel ( fig. 5 , 6 ). Leg IV with 3 pointed macrosetae, the longest on the basitarsus, shortest on the tibia ( fig. 5 , 7 ).

Measurements: Lds 330, Wds 220; Lvas 114, Wvas 107, Lian 22; Ltar IV 142; setae length: AD1 27; AD2 5; AD3 5; AD4 7; PD2 9; PD4 11; AM1 38; АМ2 5; AL1 9; AL3 18; AL4 72; PL1 20; PL2 13; PL3 11; PM1 11; PM3 61; PM4 94; AS 14; PS 13; PV 54; MCh IV: ge 65, ti 40, ta 80.

Male. Ventrianal shield triangular, with 3 pairs of preanal setae and contiguous anal pores ( fig. 5 , 8 ). The spermatodactyl curved, with a lateral process, rounded and widened at the end ( fig. 5 , 9 ). Lds 305.

D i a g n o s i s. Transeius lutezhicus reliably differs from morphologically similar species in the peculiar structure of the spermatheca with a very long funnel.

Note. The asymmetric placement of the anal pores, which was pointed out in the original description of this species, is not a reliable species trait, since it is not carry out for all individuals. The original description indicates the presence of 4–5 teeth on Df chelicerae; the specimens studied by us had 3 teeth on this finger.

D i s t r i b u t i o n, h a b i t a t, o c c u r r e n c e. Europe, the Caucasus. In Ukraine: herbs, litter, soil, nests of small mammals; rare.

Note. Description, dimensions and illustrations are based on non-type specimens from the Crimea, which were compared with the holotype .
