Genus Nannarrup n. g.

Type species. Nannarrup hoffmani n. sp.

Monotypic.

Diagnosis. Adult body length ca 10 mm. Cephalic plate only slightly longer than wide. Frontal line absent. Two small clypeal plagulae, covering ca one-sixth of the clypeus. Two additional smooth areas along the posterior part of the paraclypeal sutures, in contact with the clypeal plagulae. Buccae without setae. Stilus present, relatively short. Spiculum absent. Side-pieces of labrum only incompletely subdivided into an anterior and a posterior ala by a fragmented line very poorly marked. Mandible provided with four well-developed pectinate lamellae. Coxosternum of first maxillae divided. Coxosternum of second maxillae undivided, without suture or membranous isthmus. Metameric pores close to the posterior margin, not to the lateral ones. Telopodites of second maxillae shorter than, or just reaching, the end of the telopodites of first maxillae and just reaching the anterior limit of the plagulae. Claw of second maxillae only represented by a terminal spine. When closed, forcipular telopodites remain far behind the anterior margin of the head. Forcipular trochanteropraefemur provided with a single distal tooth, strong and pigmented; femur and tibia without teeth; tarsungulum provided with a basal tooth well developed and slightly pigmented. Forcipular tergum without median sulcus. Sternal rhachides not anteriorly furcate. Last sternum subtriangular, longer than wide. Numerous pores on the ventral surface of each coxopleuron. Anal pores present. Forty-one pairs of legs.

Etymology. From the Greek nannos, dwarf, and Arrup , pointing to the affinities of this genus to Arrup and to the very reduced size of its type (and only known) species.
