In all images, the anterior orientation is at the top of the figure, with posterior at the bottom. a Overview of the head. The lack of sclerotized/eversible head organs and/or modified head papillae is a characteristic feature of Ooperipatellus. Arrow points to remnant of ejected slime on the head of the specimen. b Detail of

Fig. 2 Features associated with male reproductive structures in Ooperipatellus nickmayeri sp. nov. Scanning electron micrographs. In all images, the anterior orientation is at the top of the figure, with posterior at the bottom. a Genital pad in overview. The posterior border of the genital pad appears modified into a conspicuous swollen area (dotted lines) in males of this species. Note the characteristic genital opening of Ooperipatellus, the cruciform opening of which divides the genital pad completely on the transverse but not on the longitudinal axis. b Detail of the modified area of the genital pad. Note the lack of dermal
