Denisovans, a sister group of Neandertals, have been described on the basis of a nuclear genome sequence from a finger phalanx (Denisova 3) found in Denisova Cave in the Altai Mountains. The only other Denisovan specimen described to date is a molar (Denisova 4) found at the same site. This tooth carries a mtDNA sequence similar to that of Denisova 3. Here we present nuclear DNA sequences from Denisova 4 and a morphological description, as well as mitochondrial and nuclear DNA sequence data, from another molar (Denisova 8) found in Denisova Cave in 2010. This new molar is similar to Denisova 4 in being very large and lacking traits typical of Neandertals and modern humans. Nuclear DNA sequences from the two molars form a clade with Denisova 3. The mtDNA of Denisova 8 is more diverged and has accumulated fewer substitutions than the mtDNAs of the other two specimens, suggesting Denisovans were present in the region over an extended period. The nuclear DNA sequence diversity among the three Denisovans is comparable to that among six Neandertals, but lower than that among present-day humans.

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.

Two New Species

Two new species of the doryctine genus Iare, I. mexicanus sp. nov. and I. cheguevarai sp. nov., are genetically and morphologically described from a tropical dry forest in Jalisco, Mexico. Iare belokobylskiji Marsh is also reported for the latter region. These species represent the northernmost distribution records for the genus. A simultaneous Bayesian analysis with COI and 28S DNA sequence data recovered the three examined species of Iare within a single clade, though with low support. This genus appears nested within a large doryctine Neotropical clade as sister group of a cluster containing species of Callihormius Ashmead, Leluthia Cameron, Histeromeroides Marsh and Panama Marsh.

Phylogenetic relationships among the families in the infraorder Sejina and the position of Sejina relative to other infraorders of Mesostigmata are re-examined based on molecular and morphological data. Data sets included DNA sequence data for complete 18S, EF-1 , partial CO1genes, and 69 morphological characters. The two families of Heterozerconina consistently group within Sejina, and we propose to synonymize Heterozerconina with Sejina (Sejina s.l). Microgyniina is not the closest relative of Sejina. Rather, Sejina s.l. most often groups with Gamasina. Uropodellidae and Ichthyostomatogasteridae are sister groups and this lineage forms the sister group to Discozerconidae plus Heterozerconidae. Overall, we recognize 5 families within Sejina: Uropodellidae, Ichthyostomatogasteridae, Sejidae, Discozerconidae, and Heterozerconidae.

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).
