Key for the identification of Hemimycale species

1 Megascleres are (subtylo-)strongyles and oxeote like tornotes; without raphides...................... H. oxeata sp. nov. - Megascleres are strongyles varying to anisostrongyles, subtylostrongyles or styles. No oxeas. Raphides may be present..... 2 2 Styles occasionally present.............................................................................. 3 - Styles never present.................................................................................... 4

3 Color in life bright red, pink or pale orange; choanosomal skeleton plumose; megascleres are (aniso-)strongyles larger than 300 x 5 µm, and styles with almost the same dimensions as the strongyles................................ H. columella

- Color in life dark greenish blue; choanosomal skeleton plumose or plumoreticulate; megascleres are (aniso-)strongyles smaller than 300 x 5 µm, and relatively short and thick styles................................................. H. arabica

4 Pore sieves circular; strongyles with asymmetrical ends....................................................... 5

- Pore sieves elongated; strongyles with symmetrical ends............................................. H. insularis

5 Megascleres longer than 320 µm.................................................................. H. rhodus

- Megascleres shorter than 320 µm......................................................................... 6

6 Color in life salmon orange with brownish tinges; strongyles never varying to subtylostrongyles; raphides absent.................................................................................................. H. mediterranea

- Color in life reddish orange; strongyles sometimes varying to subtylostrongyles; raphides present........................................................................................................... H. ceadensis sp. nov.
