Tegenaria parvula Thorell, 1875b: 94, female; Thorell, 1875a: 78, female; Brignoli, 1971a: 97–101, figs 46– 50.
Tegenaria velox Chyzer & Kulczyn´ ski, 1897: 168, 169, pl. 6, fig. 28, female, s yn. nov.
Tetrilus strandi Caporiacco, 1936: 355, 356, fig. 5, male; Caporiacco, 1938: 39, fig. 2, female; Lehtinen, 1967: 267; synonymized by Brignoli, 1977a: 45.
Malthonica parvula: Guseinov et al., 2005: 164.
Types
No type material examined. The female holotype was examined and drawn by Brignoli (1971a).
Sub Tegenaria velox: Holotype. Romania: Caras- Severin, Herkulesfürdö (Polyana Stana Pogara, Rablobarlang), ♀ (HNHM, Araneae-5), iv., Chyzer.
Other material examined
Italy (7 ♂, 13 ♀).
Diagnosis
Tegenaria parvula is very closely related to Teg. silvestris. Females can easily be separated by the distinctly different epigyne. Males are more difficult to separate but the most useful characters are the dorsal branch of the RTA, the median protrusion of the tegulum, and the distal portion of the conductor.
Description
Measurements: Male (N = 2): CL 3.31–3.90, CW 2.54– 3.07, STL 1.57–1.89, STW 1.58–1.92. Leg I (3.51–4.47, 1.29–1.45, 3.35–4.18, 3.53–4.57, 2.15–2.40), II (3.17– 4.00, 1.17–1.38, 2.79–3.54, 3.13–3.53, 1.80–1.84), III (2.50–2.90, 0.86–1.05, 2.21–2.26, 2.21–2.84, 1.12– 1.47), IV (3.78–4.55, 1.21–1.38, 3.21–3.91, 3.98–4.97, 1.82–2.21). Pedipalp (1.72, 0.55–0.63, 0.49–0.51, 2.20– 2.25), bulbL 1.90–1.96. Female (N = 1): CL 3.46, CW 2.70, STL 1.74, STW 1.75. Leg I (3.76, 1.24, 3.32, 3.66, 2.04), II (3.22, 1.18, 2.72, 2.96, 1.63), III (3.14, 1.19, 2.37, 3.07, 1.55), IV (3.99, 1.27, 3.36, 4.28, 1.84). Pedipalp (1.49, 0.63, 0.91, 1.48). EPL 0.51, EPW 0.85, ATL 0.24, ATW 0.26. Eyes: PME 0.18, PLE 0.19–0.20, AME 0.14–0.19, ALE 0.19–0.21. Eye distances: PME–PME 0.5–1 x PME, PME–AME 0.5–1 x PME, PME–PLE ≤ 0.5 x PME, PME–ALE 1 x PME, AME– AME <0.5 x AME, AME–ALE << 0.5 x AME. CLY1 1.5 x AME, CLY2 0.5–1 x ALE.
Other morphological characters: All other morphological characters (except some details of the genital morphology) examined lie within the variation presented for Teg. silvestris.
Distribution
Reported from central to northern Italy and Romania.
Discussion
Brignoli (1971a) suggested that most citations of Teg. silvestris L. Koch from Italy may refer to Teg. parvula. The present study does not support this as both forms occur in Italy.
The synonymy of Teg. velox Chyzer with Teg. parvula is based on our examination of the female holotype of the former. No additional material, in particular no males, are presently known of this taxon from Romania. No differences could be found between the holotype of Teg. velox and Italian material of Teg. parvula and the two are therefore synonymized here. Males from Romania will be necessary to confirm this synonymy.
