REMARKS
The specimens have a more inflated capitulum in the region of the base of the scutum instead of having a uniform breadth as observed by Young (1998b: 40). The rostro-latus is as high as wide in

smaller specimens (Fig. 25A) and higher than wide in larger specimen (Fig. 25B) and the rostrum is not visible between the rostro-latera. The specimens are larger than that observed by Young (1998b). The strength of the longitudinal ridges of capitular plates varies among the specimens, the smaller had them more pronounced than the larger one.
Catherinum recurvitergum has been recorded from the Azores region (type locality) and eastern Africa (Gruvel 1900a: 190; Weltner 1922: 72). The new records extend its septentrional distribution from the Bay of Biscay, France.
