Redescription of the Subterranean Millipede Antrokoreana gujoensis (Diplopoda: Julida: Nemasomatidae) from Central Honshu, Japan

Abstract

A subterranean millipede species, Antrokoreana gujoensis Masuda, 2010, is redescribed based on specimens newly collected around its type locality, in the limestone area of Mino Terrane on Honshu Island, Japan. Males of A. gujoensis were originally described as having no penes, but nonetheless, the examined specimens clearly demonstrate that this species possesses the penes behind leg-pair 2. An emended diagnosis of this species and a key to all eight currently recognized species of Antrokoreana is provided
