A review of the taxonomy, phylogeny, and zoogeography of all currently recognized Gekko species is provided based on morphology (including size, scalation, color, and pattern) and mitochondrial and nuclear DNA sequence data. We distinguish six morphological (phenotypic) species groups within the gekkonid genus Gekko: the G. gecko, G. japonicus, G. monarchus, G. petricolus, G. porosus, and G. vittatus groups, all of which receive support from molecular phylogenetics. The taxon G. reevesii, formerly evaluated as a synonym of G. gekko, is revalidated herein at specific rank. Furthermore, a preliminary identification key of all currently recognized Gekko taxa is provided.

Thoracophelia (Annelida, Opheliidae) are burrowing deposit feeders generally found in the mid- to upper intertidal areas of sandy beaches. Thoracophelia mucronata (Treadwell, 1914) is found along the west coast of North America, including at Dillon Beach, CA. Two additional species, Thoracophelia dillonensis (Hartman, 1938) and T. williamsi (Hartman, 1938) were also described from this beach. These three sympatric species have been primarily distinguished by branchial morphology, and efforts to determine the validity of the species have been based on morphological, reproductive and ecological studies. Here we demonstrate using mitochondrial and nuclear DNA sequence data that these three species are valid. Mitochondrial Cytochrome c subunit 1 (COI) sequences show uncorrected interspecific distances of ~9–13%. We found no inter—specific differences in body color or in hemoglobin concentration, but found that reproductive males were pinkish-red in color and had lower hemoglobin concentrations than purplish—red reproductive females.

Based on mitochondrial and nuclear DNA-sequence data we identify and describe an evolutionary separate lineage (Potamon pelops, sp. nov.) within the potamid freshwater crab species Potamon fluviatile (Herbst, 1785). So far, Potamon pelops, sp. nov. is only reported from the Peloponnesus Peninsula (Greece), probably allopatric to P. fluviatile. This cryptic lineage is not identical with the infrasubspecies Potamon fluviatile fluviatile natio laconis Pretzmann, 1983, the latter being within the morphological variation of Potamon fluviatile and Potamon pelops. Morphologically, Potamon pelops, sp. nov. differs from Potamon fluviatile, probably in spermatophore packing (cleistospermia in P. fluviatile versus coeno- and cleistospermia in P. pelops).
