The morphology of our specimens fits the description in Nilsson-Cantell (1921, 1938): the shell is depressed and has a sinuous junction between the tergum and scutum. The external shell morphology of O. brunnea and O. intermedia is very similar. Old and eroded specimens of O. brunnea have a sinuous junction line between scutum and tergum, which is one of the characteristics of O. intermedia described by Nilsson-Cantell (1921). There are, however, several consistent diagnostic features between O. intermedia and O. brunnea . The shell of O. intermedia is much depressed in comparison to that of O. brunnea . The junction of the tergum and scutum in O. intermedia is sinuous, even at the young stage (except for very small individuals, RC-diameter &lt;10 mm; Fig. 3). In contrast, young individuals of O. brunnea have a straight junction between the scutum and tergum, and this junction line becomes sinuous when the barnacles get older (Fig. 3). There are some variations in the number of spines (-2-4) on the region between the second and third teeth of mandibles in O. brunnea and O. intermedia (Fig. 15). But both species have similar range of variations and there are no diagnostic differences between the two species (Fig. 15). The maxillule of O. brunnea has very deep notches on the upper and lower 1/3 portions of the cutting edge dividing it into three distinct portions. While the maxillule of O. intermedia has shallow notches on the upper and lower 1/3 portions of the cutting margin looking more or less straight without being dividing into three distinct regions as in O. brunnea . Such differences are considered consistent based on observations of the additional three specimens from both species (Fig. 16).</p><p>Nilsson-Cantell (1921) has not state any deposition nor specimen number of type or paratype specimens of O. intermedia . The foreword section of Nilsson-Cantell (1921) stated majority of specimens in Nilsson-Cantell (1921) were obtained from collections in Swedish Imperial Museum in Stockholm, Sweden and Zoological Museum in Uppsala, Sweden. The specimens of O. intermedia are possibly housed in either one of the two museums above. Before checking the presences or absences of O. intermedia in museum collections in Sweden, the present study did not attempt to establish any neotypes of O. intermedia to avoid taxonomic confusion. The information of the COI gene in GenBank for O. intermedia is currently adequate for future studies to confirm identification of specimens collected.</p></div>	https://treatment.plazi.org/id/01BB691E448B58548761EEC0A01DB5BA	Public Domain	No known copyright restrictions apply.
