Figs 102-113

Type material. ♀ holotype ( PJ 2856), Colombia,? Gosomoco , 800 m, Fassl, NHMW .

Note. In a letter from Jürgen Gruber to Herbert Levi fom 1986 the questionable locality “Gosomoco” is discussed. According to information of JG reported in this letter, there is a report of the lepidopterologist A.H. Fassl from Teplitz ( Bohemia) who collected with his brother and another colleague 1888-1912 in Colombia. Fassl mentioned in one of his travel reports a “Sosomuco” where he collected one year in a mountain forest in altitudes of 800-1200 meters. This “Sosomuco” is located approximately a two day march east of Bogota.

Etymology. The specific name honours Gershom Levy (1937-2009) for his important contributions to the knowledge about spiders and scorpions from Israel and the Middle East; name in genitive case.

Diagnosis. Opisthosoma elongated, without conspicuous bright patches on its dorsal side ( Fig. 107 ). Male unknown. Female: epigynal furrows present in centre of epigyne as moderately bent rims ( Fig. 102 ); fertilisation ducts situated in the centre of internal duct system; glandular appendages of internal duct system directed dorsally, conspicuous; posterior epigynal margin with trapezoidal lobe ( Figs 103-106 ).

Description. Female (holotype). Total length 14.1. Prosoma: 5.0 long, 4.1 wide, anterior width 2.3. Opisthosoma: 9.1 long, 3.0 wide. Eye diameters and interdistances: AME 0.26, ALE 0.31, PME 0.21, PLE 0.27, AME–AME 0.16, AME–ALE 0.04, PME–PME 0.27, PME–PLE 0.27, AME–PME 0.29, ALE–PLE 0.30, clypeus AME 0.23, clypeus ALE 0.30. Palp: femur 2.5, patella 1.1, tibia 2.1, metatarsus -, tarsus 2.5, total 8.2; legs: I 7.8, 2.3, 8.5, 7.8, 2.2, 28.6; II: 7.7., 2.4, 8.4, 7.8, 2.2, 28.5; III: 5.6, 1.8, 5.9, 5.1, 1.6, 20.0; IV: 6.9, 2.0, 6.1, 6.4, 2.0, 23.4.

Chelicerae with ca. 20 denticles in a distinct field, 3 anterior and 6-7 posterior teeth ( Figs 109-110 ). Palpal claw with 5 larger teeth and 1 tiny tooth ( Fig. 112 ),

leg claw IV with 17 teeth ( Fig. 113 ). Trilobate membrane with pointed median hook and blunt lateral projections ( Fig. 111 ).

Copulatory organ as in diagnosis. Epigynal field rounded, as long as wide, with distinct anterior bands, the latter indistinctly separated from epigynal field. One slit sense organ included marginally in epigynal field. Copulatory openings situated anteriorly at medial rims ( Fig. 102 ). Internal duct system stout. Fertilisation ducts long, bent and narrow ( Figs 103-106 ).

Colouration. The colouration of the holotype female is strongly faded. Body and appendages show in ethanol a yellow-brown colour. Dorsal prosoma exhibiting a darker marginal band. Legs dorsally having small indistinct spots. Dorsal opisthosoma with bright guanine crystals, which extend laterally, and four pairs of small muscle sigilla ( Fig. 107 ).

Distribution. Colombia (known only from the type locality).
