Revision of Pylopagurus and Tomopagurus (Crustacea: Decapoda: Paguridae), with the descriptions of new genera and species .5. Anisopagurus McLaughlin, Manucomplanus McLaughlin, and Protoniopagurus new genus

In this fifth part of a six part series, the genera Anisopagurus McLaughlin and Manucomplanus McLaughlin, together with their respective species, are diagnosed in detail and illustrated. Protoniopagurus bioperculatus n. gen., n. sp., and three new species of Anisopagurus, A. actinophorus, A. vossi and A. hopkinsi, are described. Morphological variations in some of the most common or abundant species are discussed. The assignment of Pylopagurus ungulatus (Studer, 1883) to Manucomplanus is confirmed; it has proved to be the senior synonym of Manucomplanus corallinus (Benedict, 1892). Keys to species of Anisopagurus and Manucomplanus are presented.
