Doto maculata (Montagu, 1804)

Doto cf. maculata

Figure 3I

Material examined: One specimen, THA, 16 March 2022, 6.5 mm, FB, NTNU-VM-85736/NUIT-1147 ( Figure 3I ) ; One specimen, THA, 04 June 2022, 6 mm, FB, NTNU-VM-85694/NUIT-1170 ; One specimen, THA, 14 January 2023, 6 mm, FB, NTNU-VM-85696/ NUIT-1267 .

Localities: THA

Distribution and remarks: Doto maculata has been reported from southern to mid Norway ( Artskart 2024). Drifting larvae has also been recorded from the Barents Sea ( Descôteaux et al. 2021). Recent work on species delimitation of Doto , however, indicate that extreme care should be taken regarding identification of D. maculata ( Martinsson et al. 2021) . Specimens in the present study fully matched the morphological description of D. maculata and had neither pigment dots on apical tubercules nor red markings on the inner side of the dorsolateral appendages but are nevertheless reported here as Doto cf. maculata . The present records are the first records from the Tromsø region and the first records of adult animals from northern Norway.
