The known diversity of the subfamily Arrupinae amounts to 4 genera and 18 species: Arrup Chamberlin, 1912 (= Prolamnonyx Silvestri, 1919; Nodocephalus Attems, 1928) (11 species), Partygarrupius Verhoeff, 1939 (1 species), Agnostrup Foddai, Bonato, Pereira & Minelli, 2003 (3 species), and Nannarrup Foddai, Bonato, Pereira & Minelli, 2003 (3 species). See Bonato et al. (2003: 548)[1] for species counts of Arrup, Partygarrupius, and Agnostrup [24.x.2003]. See Tsukamoto et al. (2022)[2] for species count of Nannarrup [1.viii.2022].

Diagnosis from Bonato et al. (2003: 548)[1]:
Body inconspicuously tapering backwards. Leg-bearing trunk uniform in colour, without dark patches. Cephalic plate only slightly longer than wide. Usually 2 clypeal plagulae divided by a mid-longitudinal stripe, not covering more than posterior half of clypeus. Clypeal setae a few to 10s, mainly placed in 2 lateral quite long areas. Buccae without setae. Spiculum absent. Internal margin of labral anterior ala reduced to a pointed end. Posterior alae without longitudinal stripes. Posterior margin of labral side-piece sinuous, not fringed. Coxosternum of first maxillae either divided and nonareolate or undivided and areolate; anterolateral corners virtually absent. Coxosternum of second maxillae undivided or coxae connected by a membranous isthmus. Groove from metameric pore and foraminal process reaching postero-external corner of coxosternum. Telopodites of second maxillae not overreaching those of first maxillae. Forcipular tergum evidently wider than long, without a mid-longitudinal sulcus. Cerrus absent. Forcipular trochanteropraefemur stout, with a distal tooth only. Sternal mid-longitudinal sulci not furcate. Number of pairs of legs 41. Sternum of last leg-bearing segment without a pillowlike process.

Distribution from Bonato et al. (2003: 548)[1]: Eastern Asia from Hokkaido to Taiwan (Partygarrupius, Agnostrup and Arrup), central Asia (Arrup), California (Arrup). The true homeland of Nannarrup, whose only species was described on specimens collected in New York (U.S.A.), is unknown. Tsukamoto et al. (2022)[2] described two new species of Nannarrup and expanded the distribution of the genus to Japan.
