Following recent (2014–2017) collections made in the Solomon Islands by the MNHN and the NGO ESSI, we provide a checklist of the species of amphidromous freshwater shrimps of the genus Caridina H. Milne Edwards, 1837 from this region. Using morphological as well as molecular data in an integrative taxonomic perspective, we found a total of 24 species, including 11 new for science, that are described or re-described, illustrated and discussed in relation to their habitat and distribution. Newly described species are Caridina barakoma sp. nov., C. choiseul sp. nov., C. intermedia sp. nov., C. maeana sp. nov., C. nana sp. nov., C. piokerai sp. nov., C. pisuku sp. nov., C. paratypus sp. nov., C. poarae sp. nov., C. sikipozo sp. nov. and C. turipi sp. nov. Caridina gueryi Marquet, Keith & Kalfatak, 2009 is re-validated as a species distinct from C. buehleri Roux, 1934. Lectotypes are designated for C. mertoni Roux, 1911 and C. papuana Nobili, 1905. Diagnoses for 6 informative species groups are provided: C. brevicarpalis group, C. gracilirostris group, C. nilotica group, C. typus group, C. serratirostris group and C. weberi group. A map of the species distribution in the Solomon Islands, as well as the phylogenetic relationships between the species and their relatives, are provided.

Cuba has the highest diversity of snakes in the genus Tropidophis, representing 53 % of all the known species. Tropidophis steinleini sp. nov. is described from the eastern region of Cuba, raising the number of species to 17 in this archipelago. The new species is most closely related to T. wrighti, T. spiritus and T. morenoi. We discuss the phylogenetic relationships of this new species and other species of the genus in Cuba, based on molecular data, and classified them within three species groups according to the obtained tree topology.

Here, we describe four new species of Crellidae Dendy, 1922 and discuss characters and relationships from published molecular phylogenies including crellid sponges. New species proposed are Crella (Pytheas) chiloensis Fernandez, Gastaldi, Pardo & Hajdu, sp. nov., from southern Chile (15 m depth), C. (P.) desventuradae Fernandez, Gastaldi, Zapata-Hernández & Hajdu, sp. nov., from Desventuradas Archipelago (10–20 m depth), Crella (P.) santacruzae Fernandez, Gastaldi, Thompson & Hajdu, sp. nov., from deep waters off Argentina (750 m depth) and Crellomima sigmatifera Fernandez, Gastaldi & Hajdu, sp. nov., from the Chilean fjords region (ca. 20 m depth). These new species are set apart from each other and from known species mainly due to aspects of their spiculation. Chelae microscleres and acanthostyles supply characters that might be used to infer phylogenetic relationships and to verify the monophyly of Crella Gray, 1867 and Crellidae, which has seemingly been contradicted by preliminary molecular data available in the systematics’ literature. Our own interpretation of phylogenetic affinities, in the light of morphological characters from previous taxonomic studies, argues for a classification reassessment of materials (vouchers) included in these molecular phylogenies, especially in the case of Crella incrustans (Carter, 1885). We argue that currently available molecular phylogenetic outcomes for crellid sponges are not supportive of the polyphyly of Crella and Crellidae.

The genus Elaphropeza Macquart from the Oriental region is revised. In addition to the 79 known species (including seven new combinations of species previously placed within Drapetis Meigen) 51 new species are described and illustrated. The study is mainly based on freshly collected material in Singapore (544 samples, year cycle in eight stations and numerous hand captures). Smaller samples were available from Malaysia, Thailand and Cambodia. Of the 51 new species only 43 have been given a name: E. acantha sp. nov., E. asexa sp. nov., E. asiophila sp. nov., E. belumut sp. nov., E. benitotani sp. nov., E. bezzii sp. nov., E. bulohensis sp. nov., E. chekjawa sp. nov., E. combinata sp. nov., E. crassicercus sp. nov., E. darrenyeoi sp. nov., E. demeijerei sp. nov., E. equalis sp. nov., E. feminata sp. nov., E. flavicaput sp. nov., E. furca sp. nov., E. limosa sp. nov., E. luanae sp. nov., E. luteoides sp. nov., E. malayensis sp. nov., E. meieri sp. nov., E. melanderi sp. nov., E. modesta sp. nov., E. monacantha sp. nov., E. monospina sp. nov., E. murphyi sp. nov., E. neesoonensis sp. nov., E. ngi sp. nov., E. pauper sp. nov., E. pluriacantha sp. nov., E. riatanae sp. nov., E. sime sp. nov.,E. singaporensis sp. nov., E. singulata sp. nov., E. sivasothii sp. nov., E. spicata sp. nov., E. spiralis sp. nov., E. sylvicola sp. nov., E. temasek sp. nov., E. tiomanensis sp. nov., E. ubinensis sp. nov., E. yangi sp. nov., E. yeoi sp. nov. Eight species known only as females are briefly diagnosed but not named. Species (including type materials in most cases) described by C.R. Osten-Sacken, M. Bezzi, J.C.H. de Meijere, R. Senior-White, A.L. Melander and K.G.V. Smith were examined and re-described. Neotypes have been designated for E. calcarifera Bezzi, E. melanura Bezzi, E. formosae Bezzi and E. scutellaris Bezzi. Elaphropeza exul Osten-Sacken, 1882 is transferred as Crossopalpus exul (Osten-Sacken) comb. nov. Elaphropeza formosae Bezzi sensu Quate, 1960 re-described by L.W. Quate from Micronesia, is considered a new species and a new name is given: E. quatei sp. nov. All species of Elaphropeza are divided into two main species groups: E. biuncinata group and E. ephippiata group. Phylogenetic relationships within Elaphropeza are provisionally outlined. Some interesting morphological features and phenology of the species are discussed. Fourteen species have been found exclusively in mangroves. A key is given to the species of the Oriental Region (Indian subcontinent, Southeast Asia, Philippines and Taiwan, but excluding certain species of the Chinese mainland that proved to be different from the rest of the Oriental Region). A check list of the Oriental species is provided.

We conducted a phylogenetic study of neotropical subfamily Podostemoideae with a focus on Rhyncholacis and the monotypic Macarenia using molecular data (plastid: rbcL, trnL intron; nuclear: ITS). Our results placed the five included species of Rhyncholacis, one of which is newly described herein, in a moderately well supported (73 BP) clade with M. clavigera. These results support the transfer of M. clavigera to Rhyncholacis (R. clavigera); the nomenclatural changes are made. In addition, a new species of Rhyncholacis (R. paulana C.T. Philbrick & C.P. Bove) is illustrated and described. Rhyncholacis paulana is distinguished from all other species in the genus by its simple pinnately lobed leaf, which is fleshy and undulate. All other species of Rhyncholacis have leaves that are pinnately lobed, the lobes of which are repeatedly divided, or pinnately compound and characterized by finely dissected pinnate segments.

The endemic Hawaiian nitidulid genus Apetasimus is revised and a key to species provided. Originally described for a single species, Apetasimus involucer, five new species are described and five species are moved from the endemic Hawaiian genus Orthostolus. The following new species are described: Apetasimus conditus sp. nov., A. ganeademus sp. nov., A. abstrusus sp. nov., A. pleomelarrosus sp. nov., and A. debbiae sp. nov. Six species previously assigned to Orthostolus and the monotypic Cyrtostolus are moved to Apetasimus; Apetasimus guttatus comb. nov., Apetasimus sordidus comb. nov., Apetasimus expers comb. nov., Apetasimus atratus comb. nov., Apetasimus kauaiensis comb. nov., and Apetasimus subalatus comb. nov. Apetasimus are arranged in three species groups: pleomelarrosus-group, involucer-group, and guttatus-group. The involucer-group is characterized by brachyptery, and are rarely collected. The pleomelarrosus-group is fully winged and one species, A. pleomelarrosus, is locally abundant on Kauai. One member of the guttatus-group, A. subalatus, is brachypterous. All guttatus-group species are presumed extinct, with the last known collection in 1935.

A new Trox species, T. jeanae Scholtz and Inward, is described from Thailand. The new species belongs to the Trox opacotuberculatus species-group, a mainly eastern Palaearctic group consisting of 12 species. Habitus drawings of the T. jeanae adult and male genitalia are provided. All members of the species-group are re-examined, a map of species distribution and a tabulated key to the group is provided, and their male genitalia illustrated. The biogeography of the trogid genera Trox and Omorgus is discussed and contrasted. We suggest that T. jeanae sp. nov. is a relict species, persisting in a tropical region where it is now quite isolated from most other members of the predominantly Palaearctic T. opacotuberculatus species-group.
