Bowie neukoeln Jäger, 2022

( Figs 1–2 , 5–8 , 68–69 )

B. neukoeln Jäger, 2022: 98 , figs 440–446, 448–460 (♂ ♀), not examined.

Material examined. MALAYSIA: Sabah State: ♀ ( ZMMU), Borneo, Crocker Range Ridge [5°24’N, 116° 6’E], 1050 m, 28 February 1993, A.M. Emelyanov leg.

Diagnosis. Females of B. neukoeln are similar to those of B. scarymonsters Jäger, 2022 and B. binturong Omelko & Fomichev, 2023 by shape of median plate (MP) and spermathecae (Sp) as well as position of lateral teeth (LT). It can be distinguished from both species by 1) having posterior pocket (pit) of epigyne (vs. absence; cf. Fig. 8 and Jäger 2022: fig. 467, Omelko & Fomichev 2023: fig. 54); 2) spermathecae separated by gap equal to ca. 0.5 their width (vs. 1 and 0.3 of width, respectively; cf. Fig. 7 and Jäger 2022: fig. 468, Omelko & Fomichev 2023: fig. 53).

Description. Female ( Figs 1–2 ). Total length 11.75. Prosoma 6.16 long, 4.68 wide. Opisthosoma 5.56 long, 2.93 wide. Prosoma brown, with light brown median band. Median band widened and with projections near ocular area. Lateral bands almost invisible. Fovea thin, black. Clypeus brown. Chelicerae dark brown, with 3 promarginal and 4 retromarginal teeth, denticles absent. Sternum brown, without pattern. Labium dark brown. Endites dark brown with yellowish distal edge. Dorsal part of opisthosoma dark brown with distinct yellowish cardiac mark and a series of black spots. Lateral sides of opisthosoma yellowish brown. Ventral part of opisthosoma dark brown with small yellowish spots forming two V-marks. Spinnerets dark brown.

Eye diameters: AME 0.26, ALE 0.19, PME 0.40, PLE 0.34; interdistances: AME–AME 0.21, AME–ALE 0.41, PME–PME 0.25, PME–PLE 0.47, AME–PME 0.11, ALE–PLE 0.24. Clypeus height at AME 0.14, at ALE 0.54.

For palp and legs measurements see Table 1 . Palp coloration: all joints light brown. Leg coloration: femora I brown with yellow longitudinal stripe retrolaterally; II–IV brown with poorly visible yellow spots. Patellae I–IV brown. Tibiae I–II light brown; III–IV light brown with poorly visible yellow semi-rings. Metatarsi I–II light brown; III–IV light brown with poorly visible yellow semi-rings. Tarsi I–IV light brown. For palp and legs spination see Table 2 .

Female genitalia as shown in Figs 5–8 . Epigyne 1.4 times wider than long. Median plate (MP) with rounded lateral sides, without anterior keel. Lateral teeth (LT) well developed, large, located posterior of median plate, with blunt tips (in Figs 6–7 shape and position of LT changed due to maceration). Spermathecae (Sp) bottle-shaped, separated by ca. half spermatheca’s length (position of Sp could be slightly affected due to maceration).

Notes. Bowie neukoeln was previously known from Malay Peninsula only, this record is first for Borneo.

Distribution. Malaysia (Malay Peninsula and Borneo: Sabah; Figs 68–69 ).
