Tegecoelotes Ovtchinnikov, 1999: 68 .

TYPE SPECIES: Coelotes bicaudatus Paik, 1976 , by original designation.

DIAGNOSIS: Females can be distinguished by the broad epigynal teeth, the reduced atrium, and the short copulatory ducts (figs. 375, 376), males by the elongated patella and the long, but not spoonlike median apophysis (figs. 377–380).

DESCRIPTION: See description of type species (below).

DISTRIBUTION: China, Japan, Korea, Far eastern Russia (map 17).

COMPOSITION: Five species are included in this genus.

1. Tegecoelotes corasides ( Bösenberg and Strand, 1906) : male and female types from Saga, Japan, in SMF, examined. NEW COMBI­ NATION (transferred here from Coelotes ).

2. Tegecoelotes bicaudatus ( Paik, 1976) : female holotype from Mt. Ode, Korea, deposited in Kyungpook National University, Taegu, Korea, not examined.

3. Tegecoelotes ignotus ( Bösenberg and Strand, 1906) : two female types (not further designated) from Japan, in SMF, examined. NEW COMBINATION (transferred here from Coelotes ).

4. Tegecoelotes michikoae (Nishikawa, 1977) : female holotype, male and female paratypes from Minoo, Osaka Prefecture, Japan, deposited in the Osaka Museum of Natural History, Osaka, and in the Arachnological Society of Japan, Ohtemon­Gakuin University, Osaka, Japan, not examined. NEW COMBINA­ TION (transferred here from Coelotes ).

5. Tegecoelotes muscicapa ( Bösenberg and Strand, 1906) : male holotype from Saga, Japan, in SMF, examined. NEW COMBINATION (valid species, transferred here from Coelotes ).

Tegecoelotes bicaudatus: Ovtchinnikov, 1999: 68 ,

figs. 16–20. Male first described.

DIAGNOSIS: Females can be distinguished from those of T. corasides by the relatively narrow epigynal teeth and the small, anteriorly situated copulatory ducts (figs. 375, 376), males by the short, slender conductor and the spiral median apophysis (figs. 378, 380).

DESCRIPTION: Total length 7.00 –9.50. From front, anterior eye row slightly procurved, posterior row procurved; eye sizes and arrangements: AME smallest, ALE largest, PLE and PME subequal, slightly smaller than ALE; AME­AME subequal to AME­ALE, ALE­PLE close together, PME­PLE separat­ ed by roughly their diameter or slightly longer, PME­PME separated by roughly their diameter or slightly shorter. Clypeal height slightly less than twice AME diameter; chilum divided. Chelicerae with teeth on both margins. Labium as long as wide. Length of female first leg patella + tibia longer than carapace length.

Tarsal organ of this species not examined. Tarsal organ of T. corasides on distal end of tarsus, anterior of distalmost trichobothrium. Female spinnerets: ALS with 2 major ampullate gland spigots (MAP), about 46 piriform gland spigots; PMS with 1 or 2 minor ampullate gland spigots (mAP), about 31 aciniform gland spigots, 2 cylindrical gland spigots (CY); PLS not fully expanded in examined specimen, with about 34 aciniform gland spigots, cylindrical gland spigots not seen (figs. 381–383).

Epigynum with broad epigynal teeth, close together; atrium reduced to atrial slit; copulatory ducts short, situated anterad of spermathecae; spermathecal heads short, broad; spermathecae with stalks extended laterally, bases small, situated medially (figs. 375, 376). Male palp with patella strongly elongated; patellar apophysis present; RTA long, with distal end strongly extended; lateral tibial apophysis present; cymbial furrow short; conductor moderately long, with apex close to apex of median apohysis; conductor dorsal apophysis slender; conductor lamella not well developed; embolus prolateral in origin, short, linear; median apophysis not spoon­ like, long, spiral, with distal end grooved and supported conductor apex; base of median apophysis membranous, slightly expanded (figs. 377–380).

MATERIAL EXAMINED: RUSSIA: Far East: S­Primorie, ‘‘Kedrovaya Pad’’ Reservation in a living house, June 12–December 24, 1977, 2 males and 2 females (B. P. Zakharov, SZM). SOUTH KOREA: Moon­Kyang­ Sae­Jae, August 20, 1990, 1 male (J. P. Kim, KAI).

DISTRIBUTION: Korea, far eastern Russia.
