Description
Male (Fig. 1 View Figure 1 A-C, Fig. 2 View Figure 2 A-C, Fig. 4 View Figure 4 A-E). TL 8.1, PL 3.9, PW 2.6, AW 1.7, OL 4.2, OW 2.5, ClH 0.21, ChL 1.98, ChW 0.83, LL 0.63, GL 1.92. Eye diameters; interdistances: AME 0.13, ALE 0.22, PME 0.15, PLE 0.18; AME-AME 0.09, AME-ALE 0.05, PME-PME 0.09, PME-PLE 0.16, AME-PME 0.07, ALE-PLE 0.03. Palp and leg measurements: palp 3.6 (1.3, 0.4, 0.3, -, 1.6), I 10.4 (2.8, 1.3, 2.5, 2.3, 1.5), II 9.7 (2.6, 1.2, 2.2, 2.2, 1.5), III 8.5 (2.3, 1.1, 1.8, 2.1, 1.2), IV 11.4 (2.9, 1.3, 2.7, 2.9, 1.6); leg formula 4123. Spination of legs: femur I p002, d110, II p001, d110, III p011, d110, r001, IV p001, d110; patella III p1, r1, IV r1; tibia I v222, II v122, III-IV p11, r11, v222; metatarsus I-II v223, III p122, r122, v2(1)22, IV p122, r1112, v222. Chelicerae with 3 promarginal and 3 retromarginal teeth, without denticles in cheliceral furrow or escort setae at base of fang. Chelicerae bulging strongly frontally (Fig. 4 View Figure 4 E: black arrow), femora I bulging slightly dorsally (Fig. 4 View Figure 4 E: white arrow).
Palp as in diagnosis (Fig. 1 View Figure 1 A-C, Fig. 2 View Figure 2 A-C). With one apophysis each on patella and tibia. Embolus thin, arising from tegulum in a 7.30- o’clock-position (Fig. 1 View Figure 1 B, Fig. 2 View Figure 2 B). Conductor massive and complex, retrolateral branch with acute retrolaterad tip (Fig. 1 View Figure 1 B, Fig. 2 View Figure 2 B); dorsal part of the conductor well developed, forming a furrow with the ventral part, visible in retrolateral view (Fig. 1 View Figure 1 A, Fig. 1 View Figure 1 C, Fig. 2 View Figure 2 A, Fig. 2 View Figure 2 C. Median apophysis membranous, bulging retrolaterally (Fig. 1 View Figure 1 B, Fig. 2 View Figure 2 B).
Colouration (Fig. 4 View Figure 4 A-E). Deep yellowish- to reddish-brown. Prosoma with longitudinal fovea and anterior part darker, i.e. reddish-brown. Chelicerae deep reddish-brown. Other appendages yellowish- to reddish-brown, with tibiae-tarsi and femora I dorsally darker. Opisthosoma dorsally dark brown in anterior half and with distinct chevron-pattern in posterior half, laterally dotted, ventrally light greyish-brown with few dots. Spinnerets pale yellow.
Female. See Brignoli (1978) and Wang and Zhu (2009)
Variation. Males (n = 3): TL 8.0-8.6, PL 4.0-4.3, OL 4.0-4.3. Females (n = 4): TL 9.3-9.5. PL 3.6-4.2, OL 5.3. Epigynal teeth may be well separated over their entire length or fused to a certain extent. The number of the so-called "fusion bubbles" (= sclerotised spheres indicating a zone where two structures fused together, for example, median septum and lateral lobe) in the posterior part of the epigyne varies.
Diagnosis
Coelotes vignai seems to be closely related to Coelotes coenobita by the shape and the position of the epigynal teeth that are long, reaching almost half of the epigynal length, situated close together with their bases situated under the epigynal hood (Fig. 3 View Figure 3 A-E; Brignoli 1978: fig. 137). Coelotes vignai can be distinguished from the latter by the broader epigynal hood which is not so strongly bent as in C. coenobita and by the copulatory openings distinct and slit-like with meandering posterior rim (Fig. 3 View Figure 3 A-C and E) where C. coenobita has less distinct copulatory openings with semicircular posterior rim medially ( Brignoli 1978: fig. 137). The male palp differs distinctly from all the other species of Coelotes by the deeply notched ventral part of the conductor, forming an acute angle, with broad and proximally bulging retrolateral branch of conductor (Fig. 1 View Figure 1 A-C, Fig. 2 View Figure 2 A-C).
