Abstract

ABSTRACTCover illustration. Haplogynae are highly diverse group of spiders with respect to the primary male genital system and sperm characteristics. Within this group, different sperm transfer forms evolved, i.e., individually transferred sperm (cleistospermia), sperm conjugates (primary and secondary sperm conjugates). In this issue of the Journal of Morphology, Lipke et al. (pp. 1238–1257 10.1002/jmor.20298) study the evolution of sperm transfer forms in Orsolobidae by using histology, TEM and X‐ray microscopy. The cover image shows a 3D‐reconstruction of a sperm conjugate of Tasmanoonops alipes comprising two spermatozoa that are arranged opposed to each other.
