A comprehensive knowledge of relationships between coral and coral-associated organisms is essential for the conservation studies of the coral reef community, yet the biodiversity database of coral-inhabiting copepods remains incomplete. Here we surveyed in a widely distributed scleractinian coral, Psammocora columna Dana, 1846, and newly discovered two endoparasitic copepod species, Xarifia yanliaoensis sp. nov. and Xarifia magnifica sp. nov. These two new species are described based on specimens collected in Taiwan, and they share several common morphological characters of Xarifia copepods, i.e., region dorsal to fifth legs having three posteriorly directed processes unequally. However, X. yanliaoensis sp. nov. is distinguishable from other species by the morphology of the endopods of legs, antenna, maxilla, and maxilliped (in both genders). The morphological characters of X. magnifica sp. nov. are the endopods of legs, leg 5, and maxilliped in the male. Including the two new species described in the present work, the genus Xarifia Humes, 1960 belongs to the cyclopoid family Xarifiidae Humes, 1960 currently consists of 94 species, and eight of them live in association with the Psammocora coral. A comparison table and a key to the species of Xarifia from Psammocora corals are given herein.

We revise the Neotropical snail-feeding Charadrella and add two new species to it, one from Bolivia and one from Brazil. Additionally, we perform a cladistic analysis of the genus, based on morphological characters. Parsimony analyses were carried out under equal and implied weights. Our matrix included 25 species from nine Neotropical and three Afrotropical genera, including the snail-feeding Cariocamyia Snyder (Neotropical), Aethiopomyia Malloch, Alluaudinella Giglio-Tos and Ochromusca Bigot (Afrotropical). The following relationships between the species of Charadrella were recovered: (C. albuquerquei (C. macrosoma (C. malacophaga (C. boliviana, sp. nov., C. nambikwara, sp. nov.)))). In our chosen topology, the clade that includes Charadrella has the following topology (Dichaetomyia (Alluaudinella (Ochromusca (Itatingamyia (Cariocamyia, Charadrella))))), supporting the placement of the genus in the Dichaetomyiinae.

Two new species, Flavoperla retusata Mo, Li & Wang, sp. nov. and F. yangi Mo, Li & Murányi, sp. nov. are proposed from the Guangxi Zhuang Autonomous Region of southern China. Distinctness of the new species is based on morphological characters and DNA sequence comparisons with their closest known relative, F. galerispina Mo, Wang & Li, 2020. The taxonomic relationships of the two new species and related congeners are discussed.

The study is based on new material from the collections of the Naturalis Biodiversity Centre in Leiden (RNHM) and the Hungarian Natural History Museum (HNHM) and addresses issues in two genera: Epeus Peckham & Peckham, 1886 and Ptocasius Simon, 1885 from Thailand. Both genera are of Asian/Indomalayan origin, the latter with a diversity hotspot in the subtropical valleys of the Himalayas. Based on morphological data, we propose three new species of Epeus (Epeus daiqini sp. nov. (♂♀), Epeus pallidus sp. nov. (♀), Epeus szirakii sp. nov. (♀)) and two new species of Ptacasius (Ptocasius metzneri sp. nov. (♂♀) and Ptocasius sakaerat sp. nov. (♀)). Additionally, we redescribed E. tener (Simon, 1877) and added photographs of morphological characters. The genus Ptocasius is redefined due to the inclusion of 37 species, previously included in Yaginumaella Prószyński, 1979. Relationships and distribution of both genera are discussed in reference to molecular, morphological and distributional data, published by other authors in recent years.

Two new species of the damselfly genus Euphaea Selys, 1840 (Odonata: Euphaeidae) are described from the Western Ghats of Satara District, Maharashtra, distinguished by their distinct morphology and coloration. E. thosegharensis Sadasivan & Bhakare sp. nov. is similar to E. cardinalis (Fraser, 1924), but is distinguished by the extensor and flexor surface of all femora black while all femora bright red in E. cardinalis; apical fourth of Hw black while apical half of Hw black in E. cardinalis; genae reddish-orange, black in E. cardinalis; a tuft of sparse stub black hair on either side of tergite of S9 while both S8 and S9 with tufts of long ventral hairs in E. cardinalis.  Male genital vesicle matt black, with distal border rounded angles, while vesicle black and hexagonal in shape with rounded angles in E. cardinalis and S9 twice the length of S10, while S9 and S10 of equal length in E. cardinalis. E. pseudodispar Sadasivan & Bhakare sp. nov., is very close to E. dispar (Rambur, 1842), but is differentiated easily by the absence of yellow patch on legs as in E. dispar; only apical fifth of Hw black; genae being yellowish-white, while black in E. dispar; male genital vesicle brownish-black & rhomboid-shaped and with no transverse rugosities while black with distal border rounded and with fine transverse rugosities in E. dispar; penis with single seta on each side while E. dispar has three pairs; sternite of S9 very prominently extending ventrally like a beak in comparison with E. dispar.  We have identified additional morphological characters useful in taxonomy of Euphaea of the Western Ghats for example, tufts of ventral hairs on terminal abdominal segments genital vesicle, penile structure of males and sternite of S9 in the males, and vulvar scales of females.  A taxonomic key to all known species of genus Euphaea of the Western Ghats is also provided.

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.

Two new species of the weevil genus Rhamphus from Italy are herein described: R. bavierai n. sp. (Sicily) and R. hampsicora n. sp. (Sardinia). Both are morphologically and from a molecular perspective close to R. oxyacanthae (Marsham, 1802) and R. monzinii Pesarini & Diotti, 2012. Aside from a diagnostic description and a synoptic key, distribution data and notes on the host plants of the four species are reported. Whereas R. monzinii can be distinguished by several morphological characters, the other three species are morphologically very similar to each other and separable only by the combination of a few subtle characters. On the contrary, a preliminary molecular study revealed substantial divergences of mtCOI from 6.2 to 14.9% between the species, confirming the importance of an integrative taxonomy.

A survey of freshwater fungi on submerged wood in China and Thailand resulted in the collection of three species in Dictyocheirospora and four species in Dictyosporium including two new species in the latter genus. Morphological characters and phylogenetic analyses based on ITS, LSU and TEF1α sequence data support their placement in Dictyocheirospora and Dictyosporium (Dothideomycetes). An updated backbone tree is provided for the family Dothideomycetes. Descriptions and illustrations of the new taxa and re-collections are provided. Four new combinations are proposed for Dictyocheirospora.
