Paratanytarsus dissimilis (Johannsen, 1905) or P. inopertus (Walker, 1856)

Paratanytarsus confusus Palmen or inopertus (Walk.): Reiss 1980: 149 (North Korea).

Paratanytarsus dissimilis (Johannsen, 1905): Langton et al. 1988: 319 (= confusus Palmén, 1960). Paratanytarsus dissimilis (Johannsen, 1905) & Paratanytarsus inopertus (Walker, 1856): Giłka 2011a: 39, 40 (males in key, figs 122–131).

Remarks. The two specific names, including Paratanytarsus confusus, were alternatively mentioned by Reiss (1980), thus we assume that at least one species has been found in North Korea. Later synonymization of P. confusus with P. dissimilis enabled a clear definition of this species (Langton et al. 1988). Diagnostic characters for adult males of the two sibling species, P. dissimilis and P. inopertus, compared Giłka (2011a) in the couplet 6 of the key for Paratanytarsus . Though both are eurytopic and widespread in the Holarctic (Giłka 2011c), none has been confirmed in the presently examined material.
