Cambodiparmarion doroshenkoi Kuznetsov & Kuzminykh, 1999 Figs 4F , 11A

Cambodiparmarion doroshenkoi Kuznetsov & Kuzminykh, 1999: 113-116, figs 1, 2. Type locality: In tropical forest between Motel Lomherkay and Hotel Koh Pos, SW end of Kompong Som [= Sihanoukville], Kompong Som district, Kampot province, Cambodia.

Material examined.

Locality no. 12: CUMZ-CM108 (4 shells). Locality no. 13: CUMZ-CM130 (2 shells), CUMZ-CM131 (1 specimen in ethanol; Fig. 4F ). Locality no. 11: CUMZ-CM083 (1 shell; Fig. 11A ), CUMZ-CM084 (9 shells). The semi-slug was found to live on tree trunks and leaves in the limestone area.

Distribution.

Known only from the type locality ( Kuznetsov and Kuzminykh 1999).

Remarks.

This monotypic genus was recently described. It differs from the genus Microparmarion Simroth, 1893 in having an enlarged and long cylindrical gametolytic sac, while the latter has a short and globular gametolytic sac. When C. doroshenkoi was described, the authors did not mention the characters used to discriminate this species from Parmarion martensi Simroth, 1893. Here, we provide supplementary distinguishing characters as C. doroshenkoi has a solid, ear-shape shell with ca. 2 whorls, a blackish body and mantle, and a long flagellum, while P. martensi has a thin nail-shape shell with a trace of shell coiling, a greyish to blackish body and a short flagellum ( Simroth 1893, Kuznetsov and Kuzminykh 1999).

Breure et al. (2018: figs 1196, 1197) illustrated the syntype of Vitrina unguiculus Morelet, 1865 described from “Cochinchina”. The syntypes are very similar in all characters to the shells of C. doroshenkoi examined herein. Further collections are needed to generate anatomical and molecular data to confirm whether they are conspecific or not.
