Palaeozygopleura hanusi Horný, 1955

Holotype. NMP 34886 (Horný 1955: pl. VI, fig. 3).

Paratype. NMP 34887 (Horný 1955: pl. VI, fig. 4) plus 30 unnumbered specimens, NMP.

Type locality. Section in small quarry NE of the village of Holynĕ and W of the Prastav quarry (50°1'57.627"N, 14°21'5.471"E).

Type horizon. Uppermost part of Třebotov Limestone (Daleje-Třebotov Formation); the latest Emsian to early Eifelian, Middle Devonian.

Remarks. Palaeozygopleura hanusi, P. prantli and P. bohemica come from the same stratigraphic level at their type locality. Frýda and Bandel (1997) noted occurrences of transitional forms among these species and they concluded that the species may represent synonyms. Detailed morphometric analysis of these taxa is a subject of on-going master thesis.

Stratigraphic and geographic distributions. This species has hitherto only been known from its type horizon and locality.
