Macrochlamys (?) tecta (Souleyet, 1852)

Vitrina tecta Souleyet in Eydoux & Souleyet, 1852: 499, 500, pl. 28, figs 15-17. Type locality: environs de Touranne, en Cochinchine [Da Nang Province, Vietnam].

Megaustenia (?) tecta : Schileyko 2011: 32.

Material examined.

Syntypes NHMUK 1854.7.24.351 (2 shells; Fig. 37C).

Distribution.

Laos and Vietnam ( Schileyko 2011).

Remarks.

No material of this species was found, and only the type specimens were examined. Recently, Schileyko (2011) placed this species within the semi-slug genus Megaustenia . However, the syntypes have 5 or 6 slowly increasing whorls and a narrowly opened umbilicus, so it is more appropriate to relocate it to Macrochlamys s.l. This generic placement is provisional and waiting for future genitalia information. Note that Souleyet (1852: pl. 28, fig. 15) illustrated a live specimen with large mantle lobes, and without a caudal foss and caudal horn on the posterior end of the body, which is distinct from the typical Indian Macrochlamys s.l. (see Godwin-Austen (1883: 76-84) and Blanford and Godwin-Austen (1908: 77-79) for further comparison).
