Type specimens of the Cryptocephalus species described from the Cape Peninsula, South Africa by Fabricius (1798) and Thunberg (1787, 1827) were examined. The following nomenclatorial changes are proposed: Cryptocephalus pustulatus Fabricius, 1798 = C. repandus Thunberg, 1827 syn. nov.; Cryptocephalus sexguttatus Fabricius, 1798 = C. sexguttatus Thunberg, 1827 syn. nov.; Cryptocephalus trifurcatus Thunberg, 1827 = C. laciniatus Suffrian, 1857 syn. nov.; Cryptocephalus sinuatus Thunberg, 1827 = C. meridionalis Clavareau, 1913 syn. nov. = C. capensis Jacoby, 1904 syn. nov.; Cryptocephalus octopustulatus Thunberg, 1787 = C. octopunctatus Olivier, 1808 syn. nov. = C. capensis Harold, 1872 syn. nov.; Cryptocephalus crux Thunberg, 1827 = C. denticulatus Suffrian, 1857 syn. nov. Lectotypes are designated for Cryptocephalus sinuatus Thunberg, 1827 and C. laciniatus Suffrian, 1857. The spelling of Cryptocephalus pustulatus is fixed. All the species are redescribed, photographed and illustrated. The primary homonym Cryptocephalus crux Gebler, 1848 is replaced by its oldest available synonym C. manchuricus Gressit & Kimoto, 1961.

Described in 1857 by Eduard SUFFRIAN, the identity of the monotypic genus Achaenops remained doubtful. The type specimens were never re-examined after the original description and later lost when the collection of the Natu- ral History Museum in Hamburg was destroyed. In this study, a neotype is designated for the generic type species A. dorsalis. Two other species described later in Achaenops were not found to be congeneric with A. dorsalis, and were transferred: Lophistomus mandibularis (Jacoby, 1901: 240) comb. nov. and Acolastus nigrolineatus (Bryant, 1944: 336) comb. nov. Four species originally described in Cryptocephalus are transferred to Achaenops: Achaenops ruficornis (Suffrian, 1857: 75) comb. nov., Achaenops obscurellus (Suffrian, 1857: 76) comb. nov., Achaenops sericinus (Suffrian, 1857: 80) comb. nov., and Achaenops gilvipes (Suffrian, 1857) comb. nov. Protinocephalus weiseanus Reineck, 1913: 648 was found to be a junior synonym of A. gilvipes, and consequently Achaeno...
Semi-terrestrial talitrid amphipods of the genus Cryptorchestia (sensu Lowry and Fanini 2013) associated with freshwater-soaked leaf litter were known to occur in inland lakes of Turkey and at the shores of the Black Sea. Before 2013 they had been reported as Orchestia cavimana and later as Cryptorchestia cavimana. In our phylogenetic tree, inferred from a mitochondrial and nuclear gene dataset (cytochrome oxidase I (COI), and histone H3 (H3), respectively), we show that these Turkish populations belong to Cryptochestia garbinii, a common and widespread continental species, which is closely related to C. cavimana (endemic to Cyprus) and C. ruffoi (endemic to Rhodes). For the Turkish and European populations of C. garbinii, we found low levels of both genetic differentiation and morphological variation, and an age-related size variability (increasing at each moult) of the small lobe in the male gnathopod I merus, the main taxonomically diagnostic character for Cryptorchestia. A mainland (C. garbinii) versus insular isolation and in situ speciation (C. cavimana, and C. ruffoi) in the two east Mediterranean islands of Cyprus and Rhodes is discussed in relation to terrestrial Cryptorchestia species endemic to North East Atlantic volcanic islands
