Redescription of Meteterakis striatura Oshmarin & Demshin, 1972 (Heterakidae: Meteterakinae) from a geoemydid tortoise in China with comments on the genus.

Meteterakis striatura Oshmarin & Demshin, 1972 is redescribed from the posterior intestine of tropical tortoise Geoemyda spengleri (Gmelin, 1789) (Testudines: Geoemydidae) from China. Some characteristic features of the male reproductive system not reported previously are now reported for the present species. These include the presence of two blind diverticula near the mid-region of the seminal vesicle and a small cuticular structure near the opening of the cloaca - which we propose to name the 'scutum.' The morphological function and diagnostic value of these characters as well as presence of gubernaculum or 'gubernacular mass' in examined representatives of the genus, including paratype specimens of M. amamiensis Hasegawa, 1990 and M. ishikawanae Hasegawa, 1987 is discussed. Illustrative material is supplemented with scanning electron microscope and light microscope images of adult males and females. The molecular characterization of the species is inferred from 18S and 28S rDNA. The taxonomic composition of the genus Meteterakis is discussed and the full list of species with taxonomic remarks is updated.
