The species of the genera Spermophorodrilus BOUCHE, 1975 and Healyella OMODEO & ROTA, 1989 posses a set of characters that distinguish them from any other group of the family Lumbricidae, i.e. absence of spermathecae, short annular clitellum devoid of tubercula and the area occupied by spermatophores attached near the male pores that open in the posterior part of segment 15. The members of these two genera are mainly endemic for Anatolia, with only three species being exception. Healyella comprises nine species, seven of them endemic for Turkey: Healyella baloghi, H. boluana, H. mariae, H. michaelseni, H. naja, H. schweigeri and H. zapparolii. In addition, one species is endemic for Israel (H. jordanis) and one is Levante-Anatolian (H. syriaca). Spermophorodrilus has three species and two of them are endemic for Turkey: S. simsoni and S. vignai; the third species (S. antiquus) is endemic for the south part of the Balkan Peninsula and has not been recorded in Turkey. The present review summarises the published information on the species diversity and distribution of earthworms of the endemic genera Spermophorodrilus and Healyella.
