Neolebouria pallenisca (Shipley & Hornell, 1905) n. comb.

Synonyms: Distoma palleniscum Shipley & Hornell, 1905; Plagioporus palleniscus (Shipley & Hornell, 1905) Yamaguti, 1952; Hamacreadium palleniscum (Shipley & Hornell, 1905) Yamaguti, 1953 .

Records. From a “filefish or triggerfish, Balistes sp.” off Sri Lanka by Shipley & Hornell (1905) as D. palleniscum .

Remarks. The excretory vesicle was not described in this species, and the ovary is tri-lobed. The genital pore is distinctly post-bifurcal, but also inter-caecal, and it therefore is most similar to species of Neolebouria belonging to the “maorum” body-type of Dronen et al. (2014). Notably, one of these species, Neolebouria cantherini (Li, Qiu & Zhang, 1988) Cribb, 2005, is known from a monacanthid (i.e. a filefish), and another, N. capoori, from Indian waters. Neolebouria pallenisca n. comb. is distinguishable from other Neolebouria species of the “maorum” bodytype by its larger size, at 5,000 µm long.
