A new phylogeny for the Pristimantis lacrimosus species group is presented, its species content reviewed, and three new species described from the eastern slopes of the Ecuadorian Andes. Our phylogeny includes, for the first time, samples of P. aureolineatus, P. bromeliaceus, and P. lacrimosus. The morphology of hyperdistal subarticular tubercles is also assessed among 21 species of Pristimantis. The P. lacrimosus species group is composed of 36 species distributed in the Chocó, Guiana, and Amazon regions of tropical South America with a single species reaching Central America. Ancestral area reconstruction indicates that, despite its high diversity in the Amazon region, the P. lacrimosus group originated in the Pacific basin, Chocó region of Ecuador and Colombia. Pristimantis amaguanaesp. nov. is most closely related to P. bromeliaceus. It differs from P. bromeliaceus by being smaller, having transversal dark bands in the hindlimbs (absent or faint in P. bromeliaceus) and the absence of discoidal fold (present in P. bromeliaceus). Pristimantis nankintssp. nov. and P. romeroaesp. nov. are part of a clade of predominantly light-green frogs that includes P. acuminatus, P. enigmaticus, P. limoncochensis, and P. omeviridis. Pristimantis nankintssp. nov. and P. romeroaesp. nov. can be distinguished from all of them by the presence of a dark dorsolateral stripe that borders a light green band on a green background. Hyperdistal tubercles are present in all examined species of the P. lacrimosus species group and its sister clade. Species with hyperdistal tubercles are characterized by having relatively long terminal phalanges and narrow T-shaped expansion at the end of the terminal phalange. We discuss the phylogenetic distribution of these characters and their potential diagnostic significance.

The monotypic tachinid genus Opsozelia Townsend, 1919 (Diptera: Tachinidae) is synonymized with ZeliaRobineau-Desvoidy 1830, syn. nov. The single species of Opsozelia, O. discalis Townsend, 1919, is redescribed as Zelia discalis, comb. nov., based on examination of the holotype from Guyana and additional material from Suriname, Brazil and Paraguay. Three new species of Zelia similar to Z. discalis are described from Brazil: Z. magnasp. nov., Z. guimaraesisp. nov. and Z. formosasp. nov. These four species are treated informally as the Zelia discalis species group. An identification key to the species of this species group is provided based on male specimens. Descriptions and illustrations are provided for the male terminalia of all species and for the female terminalia of one species, Z. guimaraesi.

Abstract The fauna of bristletails of the genus Lepismachilis Verhoeff, 1910 in Montenegro and Serbia includes only one species L. (Berlesilis) targionii (Grassi, 1887) with 2 + 2 eversible vesicles on abdominal urocoxites II–VI. Three new species of this genus are described: L. (Lepismachilis) prijepolja sp. nov., L. (Lepismachilis) limensa sp. nov. from Serbia, and L. (Lepismachilis) alexandrae sp. nov. from Montenegro. All described new species belong to the species group of the subgenus Lepismachilis s. str. with 2 + 2 eversible vesicles on abdominal urocoxites II–V. Lepismachilis prijepolja sp. nov. differs from L. y-signata Kratochvíl, 1945 and L. notata Stach, 1919 by the color, drawings and ratios of the compound eyes; ratios of sensory field on fore femur of male, number of divisions of ovipositor. Lepismachilis limensa sp. nov. differs from L. hauseri Bitsch, 1974 and L. abchasica Kaplin, 2017 by ratios of paired ocelli, sensory field on fore femur of male; ratios and chaetotaxy of maxillary and labial palps. Lepismachilis alexandrae sp. nov. differs from L. abchasica by the drawings of the compound eyes; ratios of paired ocelli, sensory field on fore femur of male; number of divisions of the parameres and gonapophyses. A list of the Machilidae occurring in Balkan Peninsula is also provided.

Three new species of Anaulacomera are described, Anaulacomera (Anaulacomera) mariellae sp. n. and Anaulacomera (Anallomes) arlindoi sp. n., belonging respectively to the Inermis and Lanceolata species group, and Anaulacomera angelinae sp. n., placed as incertae sedis. The individuals were collected at the Iguaçu National Park and adjacent small fragments of Atlantic Forest, in southwestern Paraná state, Brazil. The description was based on external morphology of males. We also present distribution maps for the species of the Inermis and the Lanceolata species groups.

The morphology of the genus Scapheremaeus Berlese, 1910 is reviewed and characters of taxonomic utility delineated. Based on the morphological review, some 13 species-groups are outlined based on major morphotypes. There are two main categories: i) species that have a complete circumdorsal scissure with plicate microsculpture on the circumnotogastral plate and strongly contrasting microsculpture (foveolae, ridges or tubercles) on the centrodorsal plate (plicate species-groups), and ii) species with the circumdorsal scissure complete, incomplete or absent but with little or no contrast in microsculpture between the central and lateral regions: typically both regions foveolate or reticulate (non- plicate species-groups). A catalogue of world species of Scapheremaeus is provided. Scapheremaeus petrophagus (Banks, 1906) is not a Scapheremaeus but belongs to an undetermined genus in the Ameronothroidea. Cymbaeremaeus cyclops Oudemans, 1915 is recombined to Scapheremaeus. Five new species are described (S. angusi sp. nov., S. cheloniella sp. nov., S. ewani sp. nov., S. lambieae sp. nov., and S. pulleni sp. nov.) from soil and litter habitats in semi-arid Mallee eucalypt vegetation at Bookmark Biosphere Reserve, South Australia. These are the first members of the genus Scapheremaeus to be described from Australia, though undescribed species have been recorded previously. All the new species are morphologically closely-related and belong to a single species-group: Carinatus.

AbstractThree new species of snapping shrimps of the genusAlpheusare described from the Persian Gulf. These belong to theAlpheus edwardsiispecies-group, which is mainly characterized by unarmed orbital hoods and the presence of dorsal and ventral notches on the palm of the major chela.Alphus ankerisp. nov. shows a close affinity toA. pacificusDana, 1852 andA. heronicusBanner & Banner, 1982 bearing no balaeniceps crests in both sexes on the dactylus of the minor chela, and the merus of the major chela of both sexes are unarmed. This species differs from the closely related species by the absence of an overhanging proximal shoulder in the major chela. The other rock crevice inhabiting species,A. mohammadpourisp. nov. is diagnosed by exhibiting sexual dimorphism in its balaeniceps crests and the armed merus of the major chela. These two characters are similar to those recorded for three sandy/rubble dwelling species:A. inopinatusHolthuis & Gottlieb, 1958,A. lobidensDe Haan, 1849 andA. australiensisBanner & Banner, 1982. This new species is distinguishable from these latter species by the shape of the minor chela and colour pattern. A coral inhabiting speciesA. abumusasp. nov. appears to be closely related toA. maindroniCoutière, 1898, showing an armed merus of the major chela and the absence of spine-like seta on the ischia of the third legs. This last new species is easily discriminated fromA. maindroniby longer antennular segments, a markedly concave frontal margin between the rostrum and orbital hood, and a different colour pattern.

Three new species of the genus Oligaphorura are described from southwestern China (O. wanglangensis sp. nov.) and Russian Far East (O. ussurica sp. nov. and O. kedroviensis sp. nov.). The first species is most similar to O. inya (Weiner & Kaprus’, 2014) known from the Altai Mountains, and can be distinguished from the latter by larger body size and the number of ventral psx (00/000/121101m in O. wanglangensis sp. nov. vs 1/000/212101m in O. inya). The other two species, together with O. montana Weiner, 1994, O. pseudomontana Sun & Wu, 2012 and O. chankaensis Sun & Wu, 2012, form a distinct species-group characterized by the presence of 4+4 pso on antennal base and full-sized anal spines. Both these new species differ from the known congeners of this group by having only 2+2 posterior pso on the head. O. ussurica sp. nov. and O. kedroviensis sp. nov. can be separated due to different number of abdominal pso, i.e. 5(6)5554 in the former vs 44454 in the latter species.
