Description

Measurements: Male (N = 1): CL 2.86, CW 2.33, STL 1.50, STW 1.41, OL 3.59, OW 2.33. Leg I (4.00, 1.25, 3.50, 3.75, 2.30), II (3.80, 1.13, 3.20, 3.58, 1.92), III (3.54, 1.05, 2.75, 3.33, 1.62), IV (4.30, 1.14, 3.65, 4.65, 2.08), Pedipalp (1.54, 0.49, 0.61, 1.57), bulbL 1.40. Female (N = 1): CL 3.97, CW 2.94, STL 1.91, STW 1.88, OL 5.65, OW 3.69. Leg I (5.61, 1.66, 5.25, 5.53, 2.73), II (5.46, 1.61, 4.66, 5.24, 2.46), III (4.87, 1.46, 3.75, 5.05, 2.18), IV (5.87, 1.45, 5.26, 6.90, -). Pedipalp

(1.86, 0.71, 1.18, 1.88). EPL 0.68, EPW 0.90, ATL 0.19, ATW 0.37. Eyes: PME 0.16–0.18, PLE 0.16–0.20, AME 0.12–0.13, ALE 0.15–0.18. Eye distances: PME– PME 0.5–1 x PME, PME–AME 1 x PME, PME–PLE 0.5–1 x PME, PME–ALE 0.5–1 x PME, AME–AME ≤ 0.5 x AME, AME–ALE ≤ 0.5 x AME. CLY1 1.5– 2.5 x AME, CLY2 1–1.5 x ALE.

Male palp: RTA with three branches, ventral branch long drawn-out lobe reaching more than two thirds of tibia length, with distinct lateral ridge, lateral branch strongly sclerotized, as broad as long, distally broadly pointed, dorsal branch broad and strongly sclerotized, distally obliquely truncated, and stepped. Filiform embolus length more than 3 x CB, originating at 7 o’clock position, distal tip at 4 o’clock position. Conductor with distal portion strongly elongated, lateral margin completely folded. Terminal end moderately bifid, ventral part simple flat pointed, dorsal part consists of indistinct small peak. Connection of conductor to tegulum moderately sclerotized. MA originating at 5–6 o’clock position, strongly protruding, distally with hook-like sclerite. MS membranously connected to tegulum. Basal part of tegulum clearly visible and undulated.

Epigyne and vulva: Epigyne with distinct median region separated anteriorly from the epigynal plate by distinct rim. Median region membranous. Posterior sclerite expressed as strongly sclerotized, semicircular bar, limiting atrial area posteriorly. CO laterally between membranous median area and the posterior sclerite. Epigynal ‘pseudo teeth’ absent. Vulva consists of CBD, no distinct RC. First part (CD) of CBD moderately sclerotized and convoluted around second part, which is strongly sclerotized and convoluted. FD only represented by small, leaf-shaped appendages.

Other important characters: Cheliceral promargin with four, retromargin with four teeth. Colulus developed as trapezoidal plate with the distal margin medially moderately notched. Same pattern of distal spigots on PMS (in females) as described for the type species. PLS with distal segment shorter than basal segment. Tarsal trichobothria on cymbium present. Tarsal trichobothria seven to nine. Small teeth on paired claws of leg I 13. Leg spination: male palp (2–0–0–0, 2–0–0–0, 1–2–0–0), female palp (2–0–0–0, 2–0–0, 2–2–0–0), leg femora (2–2–2–0 or 2–3–2–0, 2–2–2–0, 1–2–2–0 or 2–2–2–0, 1–1–1–0), patellae (all 2–0–0), tibiae (0–0–0–1 or 0–0–0–1p, 0–1–0–2 or 0–2– 0–2, 1–2–1–2+1p or 1–2–2–2+1p, 1–2–2–2+1p), metatarsi (0–0–0–3p+1, 0–0–0–2p+1 or 0–1–0–3p+1, 0–3– 3–3p+1, 0–3–3–1p+1+2p+1), tarsi (I & II 0, III 0 or 0–0–1–0, IV 0 or 0–0–1–0).

Coloration: Margin of carapace with three connected narrow, crescent-shaped darkened spots, dorsally with two symmetrical longitudinal dark bands, serrated and not continuous. Sternum with distinct pale median band and three symmetrical pairs of pale dots laterally. Opisthosoma yellowish with dark spots and indistinct chevrons dorsally. Legs annulated. Colulus and ALS indistinctly darkened, PLS with basal segment darkened, distal segment pale.

Distribution

Reported from Catalonia (Tarragona and Gerona) and Castile and León (Burgos) in north-eastern Spain ( Ribera & Barrientos, 1986).

Discussion

Barrientos (1981) described only females of Teg. carensis . Based on somatic morphology (similar size, spination and coloration patterns), the geographical location, and resemblance to the closely related Teg. levantina ( Barrientos, 1981; Ribera & Barrientos, 1986), the male described here is tentatively referred to Teg. carensis .
