The Asian snail-eating snakes Pareas is the largest genus of the family Pareidae (formerly Pareatidae), and widely distributed in Southeast Asia. However, potential diversity remains poorly explored due to their highly conserved morphology and incomplete samples. Here, on basis of more extensive sampling, interspecific phylogenetic relationships of the genus Pareas were reconstructed using two mitochondrial fragments (cyt b and ND4) and two nuclear genes (c-mos and Rag1), and multivariate morphometrics conducted for external morphological data. Both Bayesian Inference and Maximum Likelihood analyses consistently showed that the genus Pareas was comprised of two distinct, monophyletic lineages with moderate to low support values. Based on evidences from molecular phylogeny and morphological data, cryptic diversity of this genus was uncovered and two new species were described. In additional, the validity of P. macularius is confirmed.

An integrative taxonomy approach was implemented based on analysis of genetic, phylogenetic, morphological and ecological data to identify the cryptic diversity within the Phyllodactylus lanei complex. At least six species can be identified, of which four are currently considered subspecies: Phyllodactylus lanei, Phyllodactylus rupinus, Phyllodactylus isabelae, Phyllodactylus lupitae and two corresponding to undescribed taxa, which are identified and described in this contribution. These differ from other Mexican geckos in several characters: genetic distance (DNAmt), position in molecular phylogeny (concatened data DNAmt+DNAnu), species tree, morphological characters such as snout-vent length, longitudinal scales, tubercles from head to tail, interorbital scales, scales across venter, third labial–snout scales and rows of tubercles across dorsum; there are also differences in their bioclimatic profiles (temperature and precipitation) and geographical distribution. The most recent studies on taxonomy and evolution of Mexican geckos (Phyllodactylus) show that the diversity of this group of reptiles is currently underestimated, suggesting that more research and conservation efforts are should be addressed at these lizards.

Three new Oriental Issidae genera and two new species identified by a previous molecular phylogeny analysis are described. Two new genera belong to the tribe Kodaianellini: Kodaianellissus gen. nov., type species: K. intorqueus sp. nov. from China and Tetricissus gen. nov., type species: T. philo (Fennah, 1978) from Vietnam. Another new genus representing Sarimini: Longieusarima gen. nov., type species: L. lunulia sp. nov. is described from China.

Some remarks on the family Tanzanapseudidae, with the description of three new species and the validation of the genus Acanthapseudes Roman, 1976 (Crustacea: Tanaidacea: Apseudomorpha) Two new species of the genus Tanzanapseudes Băcescu, 1975 (T. bacescui n. sp. and T. mirificus n. sp.) and one belonging to the genus Acanthapseudes Roman, 1976 (A. hansgeorgmuelleri n. sp.) from the islands Sri Lanka and Mauritius (Indian Ocean) are described and illustrated, as a result of the synonymization invalidation of the genus Acanthapseudes with Tanzanapseudes. At the same time, some morphological data on a doubtful species of the genus Tanzanapseudes (from Mozambique Channel) are presented, and manca I and II stages in T. mirificus n. sp. and manca I in A. hansgeorgmuelleri n. sp. are described, unknown in tanzanapseudids up to now. Also, new diagnoses (of the family Tanzanapseudidae and of the two genera), as well as the identification key of the genera and species of the above-mentioned family are presented.

A new genus Pusulissusgen. nov. with two new species P. phiaoacensissp. nov. and P. coronomensissp. nov. are described respectively from Vietnam and China in the tribe Parahiraciini of the family Issidae. A molecular phylogeny using combined genes (18S, 28S, COX1 and Cytb) confirms its placement in the tribe Parahiraciini. The tribe is divided into three subtribes: Scantiniinasubtribe nov. with the type genus Scantinius Stål, 1866, and Vindilisinasubtribe nov. with type genus Vindilis Stål, 1870 plus Nisoprincessa Gnezdilov, 2017, and the nominal subtribe Parahiraciina Cheng & Yang, 1991 subtribe nov. The characteristics of these subtribes are provided, with a key to identification. Genus Folifemurum Che, Zhang & Wang, 2013 is transferred to HemisphaeriiniMongolianina, and genus Gelastyrella Yang, 1994 is maintained as a valid name.

A new species Euxaldar daweishanensis Yang, Chang & Chen, sp. nov. is described and illustrated from southwestern China. The female genitalia of the genus Euxaldar is described and presented for the first time. A checklist and key to the known species of the genus are provided. A revised molecular phylogenetic analysis of the family Issidae based on combined partial sequences of 18S, 28S, COI, and Cytb is provided using both Maximum likelihood and Bayesian inference analyses.

Many studies have focused on the taxonomy and phylogeny of the family Galaxauraceae with the use of molecular markers, allied to morphological taxonomy, providing a better understanding of the phylogenetic relationships within the family, as well assisting with the specific delimitation. For the Brazilian coast, Galaxauraceae has few studies with morphological taxonomy, but lack studies with a molecular focus. The diversity of Galaxauraceae was assessed in northeastern Brazil (Bahia state) using rbcL and COI-5P, as well as morpho-anatomical analyses. We report four species from Brazil: Dichotomaria huismanii (the first report for the Brazilian coast), D. obtusata, Galaxaura rugosa, and Tricleocarpa fragilis. Molecular and morphological data supported the establishment of two new species for Galaxauraceae: Tricleocarpa laxa sp. nov. and Dichotomaria viridis sp. nov. Tricleocarpa laxa formed a well-supported clade sister to T. natalensis (South Africa, type locality) and T. cylindrica (Australia) in both rbcL and COI-5P analyses, whereas Dichotomaria viridis, formed a moderate clade sister to D. huismanii. The Brazilian sequences of D. huismanii grouped with sequences from the type locality (Bermuda) showing no intraspecific divergence for rbcL, and very low divergence values for COI-5P. The record of D. huismanii in Brazil expands its geographical distribution to the South Atlantic Ocean. Male plants are described for the first time for this species. Even though our results are restricted to a region of northeastern Brazil (Bahia), they clearly revealed a hidden diversity of Galaxauraceae in Brazil.

Herein two new species of the genusSyngastesMonard, 1924 are described from South Korea, with detailed descriptions and illustrations. Both new copepods,Syngastesmulticavussp. nov. andS. pseudofoveatussp. nov., have two inner setae on the first exopodal segment of P2 and P3.Syngastesmulticavussp. nov. most closely resemblesS. gibbosusBartsch, 1999 reported from Australia, as they both have a five-segmented antennule in the female. However,Syngastesmulticavussp. nov. has a rounded body outline instead of the gibbose outline observed inS. gibbosus.Syngastespseudofoveatussp. nov. resemblesS. foveatusBartsch, 1994 in almost all aspects. However, they differ clearly in the number of setae on the first exopodal segment of P2 and P3. We also provide a key to species of the genusSyngastesworldwide. The present study is the first record of the family Tegastidae in Korean waters.
