Ernogamasus aliitectatus ( Athias-Henriot, 1967)

( Figures 18–34 )

Pergamasus aliitectatus Athias-Henriot, 1967: 176 .

Leptogamasus (Ernogamasus) aliitectatus . — Athias-Henriot 1971: 174.

Athias-Henriot described a male of the new species Pergamasus aliitectatus ( Athias-Henriot 1967) , and shortly afterwards she augmented the species with a description of a female ( Athias-Henriot 1970), provided additional data on the male ( Athias-Henriot 1971), and transferred the species to Leptogamasus (Ernogamasus) . Juvara-Bals (1974) also presented a complementary description of this species with drawings of leg II and Tr IV in the male, as well as the endogynium in the female.

We now provide some additional description and drawings to facilitate the identification of the species. Our material has been compared with the original material by Dr. I. Juvara-Bals, who did not find substantial differences, thus confirming the species as E. aliitectatus ( Athias-Henriot, 1967) . Additional description is required because E. aliitectatus (Athias-Henriot) may be confused with the two other similar species, i.e. Ernogamasus obesus ( Holzmann, 1969) and Ernogamasus acutus (Greim, 1969) , both described in Holzmann’s PhD dissertation (1955), and validly published in 1969. Ernogamasus obesus (Holzmann) , has been reported in several European localities: Poland — the Karkonosze Mts ( Gwiazdowicz & Biernacik 2000; Gwiazdowicz 2004; Gabryś et al. 2008) and the Stołowe Mts ( Kamczyc & Gwiazdowicz, 2009), Ireland ( Arroyo et al. 2008), Germany ( Karg 1993; Werner et al. 2012, 2018), Romania ( Stanescu 2007), but at least the material collected in Poland, re-examined by the author (WW), is evidently the E. aliitectatus (Athias-Henriot) rather than E. obesus (Holzmann) .
