Monopseudocuma McCarthy and Gerken, gen. nov. Diagnosis: The genus Monopseudocuma gen. nov. can be distinguished from all others by the combination of 1 pair of pleopods in the male, and the normal structure of pereopod 1. There are fully developed exopods on pereopods 1–4 in the male, and on pereopods 1–2 in the female. There are bi­articulate rudimentary exopods on pereopods 3–4 in the female. The female antenna 2 is uni­articulate. The uropods are long and slender. Type species: Monopseudocuma gilsoni , by monotypy. Etymology: The genus is named Monopseudocuma because of the single pair of pleopods in the male and overall similarity to the genus Pseudocuma G.O. Sars. Remarks: Monopseudocuma is similar to Pseudocuma in overall form, carapace morphology, the exopods on the pereopods and the uni­articulate antenna 2 in the female. Pseudocuma differs in having 2 pairs of pleopods in the male, the second of which is rudimentary. The only other pseudocumatid which possesses a single pair of pleopods in the male is Petalosarsia longirostris Jones, 1973, and the new genus can be differentiated from Petalosarsia Stebbing 1893 by its slender, non­chelate first pereopod. : Published as part of Mccarthy, Alison M., Gerken, Sarah, Mcgrath, David & Mccormack, Grace P., 2006, Monopseudocuma a new genus from the North East Atlantic and redescription of Pseudocuma gilsoni B | cescu, 1950 (Cumacea: Pseudocumatidae), pp. 39-56 in Zootaxa 1203 (1) on page 42, DOI: 10.11646/zootaxa.1203.1.2, http://zenodo.org/record/5064368 : {"references": ["Jones, N.
