description: TEGENARIA CROATICA SP. NOV.
(FIGS 17X–Z, 19N, O)
Male unknown.
Types
Holotype. Croatia: between Trsteno and Banja, ♀ (SMF), 12.v.2006, Schönhofer.
Etymology
Named after the provenience of the holotype.
Diagnosis
Tegenaria croatica sp. nov. has a distinctly developed vulva with a broad and straight CD and a smoothly sclerotized and evenly convoluted FD that are not confusable with other species.
Description
Measurements: Female (holotype): CL 1.85, CW 1.40, STL 1.03, STW 0.94, OL 2.45, OW 1.60. Leg I (2.01, 0.79, 1.87, 1.78, 1.09), II (1.80, 0.68, 1.50, 1.54, 0.90), III (1.60, 0.60, 1.28, 1.47, 0.68), IV (2.07, 0.69, 1.90, 2.13, 1.05). Pedipalp (0.80, 0.32, 0.49, 0.79). EPL 0.27, EPW 0.55, ATL 0.09, ATW 0.20. Eyes: PME 0.10, PLE
0.11, AME 0.05, ALE 0.11. Eye distances: PME–PME 0.5–1 x PME, PME–AME 0.5–1 x PME, PME–PLE <0.5 x PME, PME–ALE 0.5–1 x PME, AME–AME 0.5 x AME, AME–ALE <0.5 x AME. CLY1 3–3.5 x AME, CLY2 1 x ALE.
Epigyne and vulva: Epigynal plate moderately sclerotized. Median plate only laterally separated from epigynal plate, medially slightly protruding. Posterior sclerite absent. Distinct CO posteriolaterally of the median plate. Vulva consists of distinguishable CD, RC, and FD. CD strongly sclerotized, bulky, and almost straight. RC globular, smoothly sclerotized, leading into consistently convoluted FD. FD ending in small, leaf-shaped appendages.
Other important characters: Cheliceral promargin with three teeth, retromargin with five equally sized teeth. Colulus developed as trapezoidal plate with the distal margin medially notched. Same pattern of distal spigots on PMS (in females) as described for the type species. PLS with distal segment as long as or slightly longer than basal segment. Tarsal trichobothria at palp tarsus and cymbium absent. Tarsal trichobothria five to six. Small teeth on paired claws of leg I seven to eight. Leg spination: female palp (2–0– 0–0, 2–0–0, 2–2–0–0), leg femora (2–1–0–0, 1–1–0–0, 1–1–0–0, 1–1–1–0), patellae (all 2–0–0), tibiae (2–0– 0–1p, 0–1–0–1, 2–2–1–1, 2–2–1–2), metatarsi (0–0– 0–3p, 0–0–0–2p+1, 0–1–0–3p+1 or 0–2–0–3p+1, 0–2– 2–3p+1), tarsi (all 0).
Coloration: Margin of carapace with dark band, two longitudinal symmetrical dark bands present but hardly recognizable (may be a result of alcohol preservation). Sternum with pale median region. Opisthosoma brown-grey-green with pale median band anteriorly continuing in chevrons posteriad. Colulus pale (probably a result of alcohol preservation), AMS and basal segment of PMS darkened, distal segment pale.
Distribution
Reported from Croatia.
Discussion
Even though Teg. croatica sp. nov. is currently known from only a single specimen, it is formally described here as it shows a very characteristic morphology of the epigyne and vulva.
