Figs 5 , 9 , 13 , 20 , 24 , 29 , 30 , 35 , 36 , 42 , 43

Remark.

This species was recently reported from the Balkans, Bulgaria ( Naumova et al. 2021). Fortunately, the record is accompanied with high quality images, and it is clear that the specimen shows some differences (i.e., in size of the cymbium, shape of the cymbium, the absence of clear finger-like extensions, and the coil shape of the spermophore) from the new species. However, we do not suggest any identification without examining the specimen itself.

Material examined.

Spain: Cantoblanco: 1 male, Monte de Valdelatas Madrid. UTM: 30TVK4287, 40°32'11.5"N, 3°41'05.0"W, 700 m, 2002 May 27. A. Jiménez leg. (PCAM 5949) .

Diagnosis.

Abdominal pattern consists of three pairs of elongated white spots. Males have blunt conductor (Figs 9 , 29 , 35 , 36 ). The female is very similar to that of the new species, but can be differentiated by the round spermathecae (Figs 42 , 43 ).

Description.

See Hernández-Corral et al. (2017) and Cornic and Ledoux (2013).

Distribution.

France, Spain and Bulgaria ( Naumova et al. 2021; Nentwig et al. 2022). A combination of all the published occurrences until 2020 ( Cornic and Ledoux 2013; Hernández-Corral et al. 2017; Breitling 2018) is shown in fig. 3.
