Genus Orgyia OCHSENHEIMER 1810

Description of the genus is in PATOČKA (1991). Genus Orgyia it is possible to identify using the key to the genera of family Lymantriidae in PATOČKA & TURČÁNI (2005) or using the modified key listed here at genus Calliteara . After including three now described pupae of Mediterranean, east European and Asian Minor species, it is necessary to modify the key to the species of genus Orgyia in PATOČKA & TURČÁNI (2005) as follows:

1 Dorsal scales on abdominal segments l-4 or 1-3 circled ( fig. 47 ).....................................2

- Dorsal scales on abdominal segments l–4 or 1-3 elongated, or bulbous ( fig. 75 ).............4

2(1) Labium narrow, much narrower and also shorter than lobes of maxillae. Prothoracic coxae not longer or slightly longer than maxillae. Groups of scales present on abdominal segments 1-3 ..................................................................................... O. recens

- Labium wide, the same in width or wider than maxillae. Prothoracic coxae respectively coxae + femora conspicuously longer than maxillae (figs 39, 51). Groups of scales present on abdominal segments 1-4 (figs 44, 54)...............................................3

3(2) Labrum transversally cut or concave at the end. Maxillae rounded at the end ( fig. 52 ). Mesothoracic coxae concealed. Ends of female antennae separated from each other ( fig. 51 ). Cremaster wide on base and strongly tapering ventrally ( figs 56-58 ) ... O. dubia

- Labrum round at the end (fig. 40). Maxillae with projection at the end (fig. 41). Also mesothoracic coxae visible. Ends of male antennae close to each other (fig. 39). Cremaster narrower on base and less tapering ventrally ( figs 48-50 )........ O. trigotephras

4(1) Antennae barely exceed ends of prothoracic coxae. Maxillae relatively narrow at the end. Cremaster obtuse at the end. Groups of scales present on abdominal segments 1- 3 ......................................................................................................................... O. antiqua

- Antennae far exceed ends of prothoracic coxae. Maxillae narrow at the end. Groups of scales present on abdominal segments 1-3. Cremaster slender and tapering to the end .............................................................................................................. O. antiquoides

- Antennae barely exceed ends of prothoracic coxae ( fig. 72 ), maxillae strongly clubbed to the end ( figs 72, 73 ). Groups of scales present on abdominal segments 1-4 ..... ................................................................................................................... O. aurolimbata Orgyia recens (HÜBNER 1819), O. antiqua (LINNAEUS 1758) and O. antiquoides (HÜBNER 1822) are elaborated in PATOČKA (1991) and PATOČKA & TURČÁNI (1952). Here we describe additional western Palaearctic species of genus Orgyia :
