ETYMOLOGY. The species epithet is a patronym honoring Petr Janšta, the collector of paratype of the new species.
DIAGNOSIS (♂ ♀). Total length 33–40 mm. Color reddish black, legs and telson yellow. Pedipalp patellar external trichobothria numbers: 4 eb, 4 eb a, 2 esb, 4 em, 4 est, 6 et, ventral aspect of patella with 7–8 trichobothria. Pectinal teeth number 8–9 in males, 7 in females. Chelicerae yellow, slightly reticulated. Male with pedipalp fingers type A, female with fingers undulate. Dorsal metasomal carinae on III–IV segments granulated. Dorsolateral metasomal carinae on II–IV segments absent. Ventrolateral metasomal carinae on II–IV segments present and smooth. Metasoma V ventrally with median carina developed. Chela length/width ratio, 2.3 in males and 2.6 in females. Metasoma IV length/width ratio, 1.95 in males and 2 in females. Telson length/depth ratio, 2.3 in males and 3 in females.
DESCRIPTION (♀ ♂). Total length about 33–40 mm in both sexes. The habitus is shown in Figs. 46–49 View Figures 46–49 . For position and distribution of trichobothria of pedipalps, see Figs. 72–78 View Figures 72–79 . Sexual dimorphism, see below in the description.
Coloration ( Figs. 46–49 View Figures 46–49 ). Base color uniformly reddish black, sternites lighter, brown, legs and telson yellow. Chelicerae yellow, slightly reticulate.
Carapace and mesosoma ( Figs. 46–53 View Figures 46–49 View Figures 50–55 ). Carapace finely granulated with several large granules in anterior part and several smooth areas; carinae are absent. The anterior margin of the carapace is almost straight. Carapace with two lateral eyes. Tergites finely granulated, without developed carina. Tergite VII lacking lateral and median carinal pairs. Sternites III–VII finely granulated, lacking lateral and median carinae. Stigmata small, narrow ellipical. Pectinal teeth number 8–9 (2x8, 4x9) in males and 7 in females, fulcra are present. Pectines have three marginal lamellae and 4–6 middle lamellae.
Metasoma and telson ( Figs. 56–63 View Figures 56–63 ). Metasoma very sparsely hirsute. Metasoma, mainly in dorsal aspect and whole metasoma V finely granulated more in males. Dorsal metasomal carinae on II–V segments distinctively irregularly granulated; dorsolateral carinae absent; ventrolateral carinae present, smooth on segments II–IV and granulated on segment V. Metasoma V ventrally granulated with median carina developed, on metasoma I–IV ventral median carina is absent. Anal arch with small pigmented granules. Telson finely granulated, elongate in females and swollen in males, with annular ring indicated in females and developed in male. Aculeus short, more curved in male.
Pedipalps ( Figs. 64–79 View Figures 64–71 View Figures 72–79 ). Pedipalps very sparsely hirsute. Patella with 24 (4 eb, 4 eb a, 2 esb, 4 em, 4 est, 6 et) external and 7–8 (3 x 7, 7 x 8) ventral trichobothria. Chela with 4 ventral trichobothria, of which V 4 is located on external surface near Eb 1. Femur and patella are granulated, femur roughly and patella with fine, reticulated granules. Femur has granulated developed carinae; ventroexternal carina incomplete. Patella with 5 complete carinae including irregular wide externomedian. DPS moderately developed. Manus dorsally with fine, rounded granules, which do not form median carina; only five chelal carinae are developed. Male with pedipalp fingers type A, female with fingers undulate.
Legs ( Figs. 54–55 View Figures 50–55 ). Both pedal spurs present on all legs, lacking spinelets; tibial spurs absent. Tarsus with single row of spinules on ventral surface, terminating distally with two essentially adjacent spinules.
Measurements. See Table 2 View Table 2 .
AFFINITIES. E. janstai sp. n. is morphologically most similar to E. concinnus (C. L. Koch, 1837) from Italy, which differs by darker colored telson and legs, and E. deltshevi Fet et al., 2014 from Bulgaria and eastern Serbia, which differs by having usually a higher number of pedipalp patellar trichobothria in et series. Both of these species differ in having pedipalp fingers type C in males while E. janstai sp. n. has type A (see Figs. 3–9 View Figures 1–9 versus Fig. 65 View Figures 64–71 ).
DISTRIBUTION. North Macedonia ( Fig. 184 View Figure 184 ).
