Spinitectoides

Spinitectoides is a genus of parasitic nematodes, belonging to the family Cystidicolidae. Species of Spinitectoides are parasitic as adults in the gastrointestinal tract of fish.[1][2][3] According to the World Register of Marine Species, the genus currently (2019) includes a single species, Spinitectoides berlandi.[2]

Description

The genus Spinitectoides is known only from larvae and females; its main characteristics are "a festooned cuticular ornament on the anterior part of body and an apical structure closely similar to this of Cystidicola".[1]

Spinitectoides berlandi was described on the basis of one larva from Trisopterus luscus and three adult females from Molva molva. No males were found.[1] The description also mentions that females from Molva molva had been previously described by Berland under the name "Spinitectus sp.".[4]

Etymology

The etymology is not clearly explained in the original description[1] but it is obvious that the name of the genus refers to Spinitectus, another genus of Cystidicolidae. The specific epithet berlandi obviously refers to Bjørn Berland,[1] a Norwegian parasitologist who described similar specimens in 1961.[4]

Hosts and localities
The common ling, Molva molva is the host of Spinitectoides berlandi

Spinitectoides berlandi is a parasite of marine fish, including pouting, Trisopterus luscus (Gadidae) and common ling, Molva molva (Lotidae). The type-locality is the Atlantic Ocean off the French coast. [1] Other localities include off the Norwegian coast [4] and off Faroe Islands.[5]
