Henlea montana Rota, 1994 ( Fig. 2 A-F)

Henlea montana Rota, 1994: 246­248 , Fig. 3 A­F.

Material examined. 1 individual was collected from Seungeon­ri, Anmyeon­eup, Taean­gun , Chungcheongnam­do. E: 126°19′57.63″ N: 36°30′44.89″, 23 May 2013 (collector: Lee J). One individual mounted on a slide was deposited at NIBR ( KOSPIV0000193704 ) .

Measurement. Length 9.12 mm, width 0.32­0.44 mm, number of segments 63 in fixed state.

Diagnosis. Brain slightly concave posteriorly ( Fig. 2A ). Pharyngeal glands in VI ( Fig. 2B ). Spermathecal ectal large, conspicuous, stalked, surrounding thickened distal end of ectal duct in a rosette­like ( Fig. 2C ). Chaetae slightly bent, in fan­shaped arrangement ( Fig. 2D ). Coelomocytes mucocytes, finely vesicular ( Fig. 2E ). Clitellum griddle­shaped, reticulate pattern ( Fig. 2F ).

Remarks. At first glance, the shape of chaetae looked like Fridericia species, so we thought it would be belong to the genus Fridericia . However, other morphological features of our specimen correspond to the previous description of the species by Rota (1994). Above all, it has petaloid glands around the spermathecae orifice ( Fig. 2C ).

World distribution. Italy, Ireland, Turkey.
