1. Anoplostoma viviparum ( Bastian 1865) Butschli, 1874

1865. Symplocostoma vivipara Bastian, Trans.Linn. Soc. London , 25 (2): 133.

1874. Anoplostoma vivipara : Butschli, Abhandl. d. Senckenb. naturf. Gesellsch. IX. Bd; 37.

Material examined: 2 ♂ (Reg. No. N. 263), Chirala,

30.vi.2014, Coll. G. Sivaleela.

Diagnostic characters: The species is characterized from other species by the large cylindrical buccal cavity, cephalic setae, position of the amphids and length of spicule.

Distribution: Andhra Coast ( Ghosh & Mandal, 2016), Pichavaram mangroves ( Chinnadurai & Fernando, 2005); continental shelf of South-western Bay of Bengal ( Ansari et al., 2012); Vellar Estuary (Ansari et al., 2014); Devipattinam and Adirampattinam; ( Sivaleela, 2016); Sundarban mangroves ( Ansari & Bhadury, 2017). Elsewhere: England- Falmouth, Blyth estuary, West Scotland, Strangford Lough, Northern Ireland.

Remarks: This species examined conforms well to the earlier description of Platt & Warwick (1983) in the long cylindrical buccal cavity, position of amphids, length of cephalic setae and length of spicules. This species was designated by Bastian (1865) and revision by Buetschli (1874).
