Spinitectus cristatus Railliet and Henry, 1915


Spinitectus cristatus Railliet and Henry, 1915  

This species was originally described by Linton (1901) from Phycis tenuis   (= Urophycis tenuis   ) from the Atlantic coast of America (Nantucket) as Filaria serrata Linton, 1892   . Various workers including Berland (1961), Rahman (1964), Scott (1987), Køie (1993) and Moravec & Klimpel (2007) concluded that the description is inadequate. According to Linton, S. cristatus   males show the following features: length 5.8; maximum breadth 0.1; over 100 transverse rows of spines; spines 0.01 long; four precloacal and six post-cloacal papillae; tail ends blindly, rounded extremity; cloacal aperture 0.16 from tail tip. Apart from the inadequacy of the description, there is an inconsistency in the lengths recorded for the spicules (0.06 and 0.03) and the illustrations of them. Site: intestinal lumen

Hosts: Phycis chesteri   ; Urophycis chuss   ; Urophycis tenuis
