Studies on the Monogenea of Plymouth. Gastrocotyle trachuri v. Ben. and Hesse, 1863

Abstract

In August, 1932, six specimens of this species were found on the gills of Trachurus [Caranx] trachurus taken at Plymouth. This is the first record of its occurrence in British waters.

Four polyopisthocotyleans (Platyhelminthes: Monogenea) from carangid fishes in the Mediterranean, off the Algerian coasts

“…1 H–J). Examination of 32 specimens of G. trachuri ( Table 1 ) revealed that the material from off the Algerian coast agrees morphologically well with the descriptions of Jones (1933) and Radujkovic & Euzet (1989) , particularly in having a terminal lappet armed with three pairs of hooks ( Fig. 1 H–J; also see figure 2C in Jones, 1933 ).…”

“…These authors provided a brief description lacking morphometric data and a poor illustration. Gastrocotyle trachuri was redescribed by Parona & Perugia (1889) and Jones (1933) . The latter author pointed out that the number of hooks reported by van Beneden & Hesse (1863) is linked to the stage of development as they probably described immature specimens ( Jones, 1933 ).…”

“…Gastrocotyle trachuri was redescribed by Parona & Perugia (1889) and Jones (1933) . The latter author pointed out that the number of hooks reported by van Beneden & Hesse (1863) is linked to the stage of development as they probably described immature specimens ( Jones, 1933 ). We fully agree with this suggestion based on the examination of the present specimens (see Fig.…”
