03CC87B0FF84281BFE84D9C5FAA3FE90.taxon	discussion	Remarks. Currently, 11 species are known in this genus in East Asia (World Spider Catalog 2022). This genus can be distinguished from other gnaphosids by the presence of a conspicuous, hook-like, retrolateral sclerotized spine on the male palpal femur (Kamura 1999). Three Cladothela species have been recorded in the Ryukyu Islands, namely: C. auster Kamura, 1997; C. parva Kamura, 1991; C. oculinotata (Bösenberg and Strand, 1906) (Shimojana 1977, 1981; Kamura 1991, 1997; Tanikawa and Sasaki 1999).	en	Suzuki, Yuya, Tatsuta, Haruki (2022): Two New Species of Ground Spiders (Araneae: Gnaphosidae) from Okinawa Islands, Japan.

03CC87B0FF84281EFC18DAC2FBF3FB7C.taxon	diagnosis	Diagnosis. Cladothela bicolor sp. nov. bears flattened cheliceral fangs and endites, with dense short stiff bristles (Fig. 1 C – I), a character shared with C. auster and C. oculinotata (Kamura 1991, 1997). However, female of C. bicolor sp. nov. can be distinguished from both species based on the following unique characteristics: an elliptical, transversely wider copulatory openings surrounded with distinctive sclerotized ridges [vs. ridges located on mesial and anterior sides of copulatory openings in C. auster; mesial and posterior sides in C. oculinotata; Figs 2 K, L, 3 A vs. fig. 3 in Kamura (1997) and figs 30, 31 in Kamura (1991)]; copulatory ducts as wide as and 2.5 times as tall as spermathecae, and curved, and close to each other before inserting to spermathecae [vs. copulatory ducts straight and narrower than spermatheca width in C. auster and 1.5 times as tall as spermathecae and bent before inserting to spermathecae in C. oculinotata; Figs 2 M, 3 B (CD) vs. fig. 4 in Kamura (1997) and fig. 32 in Kamura (1991)]; spermathecae close to each other [vs. further apart from each other in C. auster and C. oculinotata; Figs 2 M, 3 vs. fig. 4 in Kamura (1997) and fig. 32 in Kamura (1991)]. Male of C. bicolor sp. nov. can be distinguished from C. auster and C. oculinotata by the following characteristics of male palps: embolus relatively thin (embolus width / length 0.056) [vs. relatively thicker in C. auster: embolus width / length 0.106; and thinner in C. oculinotata: embolus width / length 0.032; Figs 2 Q, 3 D vs. fig. 1 in Kamura (1997) and fig. 26 in Kamura (1991)], conductor with a dark-colored distinct angular ridge on the retrolateral margin, and base of the conductor having a wide, whitish, non-sclerotized membranous region [vs. conductor having a sclerotized lobe-like structure in C. auster, ridge on retrolateral margin of conductor rounded in C. oculinotata; Figs 2 P – R, 3 C – E vs. fig. 1 in Kamura (1997) and fig. 26 in Kamura (1991)]; tegulum very weakly protruded [vs. strongly protruded in C. oculinotata; Figs 2 R, 3 E vs. fig. 27 in Kamura (1991)]. Live individuals of C. bicolor sp. nov. possess a clear bicolor body: vivid red prosoma and black abdomen (Fig. 1 A, B), readily to distinguish the new species from its congeners, which possess uniformly dark reddish brown or dark brown body color.	en	Suzuki, Yuya, Tatsuta, Haruki (2022): Two New Species of Ground Spiders (Araneae: Gnaphosidae) from Okinawa Islands, Japan.

Micaria longimana sp. nov. closely resem-bles M. dives in general appearance and elongated male palps, but can be distinguished based on the following characters: spines on the prolateral side of cymbium and palpal tibia relatively thicker (vs. relatively thin in M. dives; Fig. 5 B, C, cf. Fig. 5 E); blunt, membranous median apophysis locat-ed on distal end of the bulb (vs. MA thin and apophysis with hook-like tip in M. dives; Figs 5 A – C, 6 A – C, cf. Fig. 5 D – F); TA short, blunt and very weakly developed (vs. TA distinctively developed in M. dives; Fig. 6 A, cf.

Micaria pulcherrima Caporiacco, 1935, M. formicaria (Sundevall, 1831) and M. yeniseica Marusik and Koponen, 2002 also possess elongated male palpal tibia, but can easily be distinguished from M. longimana sp. nov. by having distinctive TA (Yin et al. 2012: fig. 636 E – G; Tuneva 2007: figs 36 – 38; Marusik et al. 2002: figs 1, 2). Micaria atropatene Zamani and Marusik, 2021 also has a similar palp but differs by lacking strong spines on prolateral side of cymbium and tibia, and bearing a distal tegular process (Zamani and Marusik 2021: fig. 8 A, B).	en	Suzuki, Yuya, Tatsuta, Haruki (2022): Two New Species of Ground Spiders (Araneae: Gnaphosidae) from Okinawa Islands, Japan.
