Review of Alaskaentomon (Protura: Acerentomidae, Nipponentominae)

ABSTRACT Our reexamination of Alaskaentomon Nosek, 1977 demonstrated that the type species, Alaskaentomon fjellbergi Nosek, 1977, and Alaskaentomon condei Nosek, 1981 are united in the presence of two granulated appendices on the calyx of the maxillary gland, filiform sensilium tl and very long sensilium a on foretarsus, presence of two pairs of A-setae on mesonotum and metanotum, and presence of medial posterior (Pc) seta on tergite VII and sternites VI–VII. They differ from each other in the position of foretarsal sensilla d and a′’, number of setae on tergite VII and sternites II–III, and position of P3 on tergites II–VI. The original descriptions are corrected and supplemented with new characters, including head chaetotaxy, seta length and porotaxy.
