Diagnosis

Revised from Wittmann et al. (2014) in order to receive Abyssomysis gen. nov. Eyeplate without distinct median cleft, plate mainly formed by a transverse median bridge, eyes rudimentary or absent. Antennal scale well developed, its smooth outer margin ending in a tooth; antennal gland hypertrophic. Labrum normal, symmetrical. Females with 2–3 pairs of oostegites. Pleopods uniramous, reduced to unsegmented endopods in both sexes, except that the fourth male pleopod may be sub-segmented in certain species. Uropods normal. Telson entire, lateral margins not serrated but for the most part or entirely smooth, terminal portions with spines, no setae.

Inventory

Three genera with a total of five species are now included: Calyptomma W.M. Tattersall, 1909 View in CoL , with only the nominotypical species C. puritani W.M. Tattersall, 1909 View in CoL , and Michthyops W.M. Tattersall, 1911 View in CoL , with M. parvus ( Vanhöffen, 1897) , M. theeli ( Ohlin, 1901) View in CoL and M. arcticus Petryashov, 1993 , finally the below described Abyssomysis gen. nov. with its only species A. cornuta gen. et sp. nov.

Distribution

The species of Calyptomma and Michthyops are mostly bathybenthic, living on or close to the sea floor of the Arctic Ocean, North Atlantic and Mediterranean. Only M. theeli has been found in a wider depth range of 27–2245 m. With the below records of A. cornuta gen. et sp. nov. the geographical range of the

tribe is extended to 17° S in the SE-Atlantic, and the bathymetrical range to the abyssobenthos down to 5460 m depth. For additional distribution data see key to species below.
