Summary In this study, we describe Labrys fuzhouensis sp. n. based on detailed morphology revealed by scanning electron microscopy and molecular data inferred from 18S and 28S rRNA. The new species differs from other Labrys species by a combination of several morphometric and morphological characters: vulva-anus distance 66-74 μm, tail length 172-182 μm, post-uterine sac 11-12 μm, excretory duct less sclerotised, and hexagon-shaped labial disc. The novelty of L. fuzhouensis sp. n. is also confirmed by multi-dimensional scaling analysis. The 18S and 28S rRNA-based phylogenies suggest that the new species nested in the Labrys clade as sister to L. chinensis. In addition to the new species description, Coslenchus rafiqi is reported from China for the first time, the description being supplemented by the first molecular data (18S and 28S rRNA) for this species.

The genus Discotylenchus is reported for the first time from Iran. Discotylenchus iranicus n. sp. is described and illustratedbased on morphological and morphometric characters. The new species is characterized by a combination of the followingmorphological features: lip region continuous and smooth, tapering to an offset prominent labial disc, lateral field withfour incisures, stylet length of 14–15μm, vulva position at 70.8–76.5 %, tail length of 81–100μm, conoid with a roundedtip and presence of males. The Iranian population of D. brevicaudatus shows a wider morphometric range compared tothe original description and the male of this species is described for the first time. The morphological characters and range of morphometric data of D. discretus are in full agreement with the original population.

This species is the first record of Lucasioides from Russia, whose location is the northernmost habitat of terrestrial isopods in indigenous habitats presently known to Eurasia. The diagnostic characters of the new species and a preliminary phylogenetic analysis within Agnaridae are provided.

The assassin bugs of the genus Ptilocerus Gray, 1831 (Hemiptera: Heteroptera: Reduviidae: Holoptilinae) occurring in the Australian Region are reviewed for the first time, resulting in the description of two new species, viz., P. spangenbergi sp. nov. (Queensland and Northern Territory, Australia) and P. papuensis sp. nov. (Papua New Guinea). The latter species differs from P. fuscus Gray, 1831 (the type-species of genus Ptilocerus) in a couple of major external morphological characters, hence its tentative placement in the genus Ptilocerus is discussed. A key for the separation of the two new species is provided.

The Lygus-complex is one of the most taxonomically challenging groups of Miridae (Heteroptera), and its Australian fauna is poorly studied. Here we examine the Australian taxa of the Lygus-complex using morphological and molecular methods. After a detailed morphological study of the material collected throughout Australia, Taylorilygus nebulosus is transferred to Diomocoris, with the genus recorded for the first time in this country. Taylorilygus apicalis, also widely distributed in Australia, is redescribed on the basis of Australian material. The genus Micromimetus is recorded for the first time in Australia, with M. celiae, sp. nov., M. hannahae, sp. nov., M. nikolai, sp. nov. and M. shofneri, sp. nov. described as new to science. Micromimetus pictipes is redescribed and its distributional range is increased. The monophyly of the Lygus-complex and relationships within this group were tested using cytochrome c oxidase subunit I (COI), 16S rRNA, 18S rRNA and 28S rRNA markers. The Lygus-complex has been found to be non-monophyletic. Phylogeny confirmed the monophyly of Micromimetus, and it has shown that Taylorilygus apicalis is closer to Micromimetus species than to Diomocoris nebulosus. This study is the initial step in understanding the Lygus-complex phylogeny; analyses with more taxa, more genes and morphology are needed to reveal the interrelationships within this group, and sister-group relationships of Australian taxa. http://zoobank.org/urn:lsid:zoobank.org:pub:7393D96B-2BBA-438D-A134-D372EFE7FB9E

The genus Procerobaetis Kaltenbach & Gattolliat, 2020 is reported for the first time from Thailand, and Procerobaetis totuspinosussp. nov. is described as a new species based on larvae. It can be easily distinguished from other known Procerobaetis species by the presence of triangular spines at the posterior margin of tergites VI–IX. COI sequences were obtained from all known species. The genetic distances (Kimura 2-parameter) between the new species and the other species are between 20% and 23%. The morphological characters of the new species and its closely related species are discussed; larval key to all species of the genus Procerobaetis is also provided.

The genus Punctulata Wang, 2006 is transferred from Oecophoridae to Autostichidae based on morphological characters and molecular data. Punctulata guangxiensis sp. nov. and P. novipalliptera sp. nov. are described as new based on the specimens collected in China. The females of P. palliptera Wang, 2006 and P. trunciformis Wang, 2006 are described for the first time. Images of male adults and male and female genitalia are provided for all the six Punctulata species along with a key to separate its species and a map showing their distribution.

The genus Pseudostegana (Okada, 1978) currently contains thirty-nine described species. A number of Pseudostegana were collected from the fieldwork in southwestern China from 2010 to 2017. Eleven new species were discovered and are described from southwestern China: Pseudostegana alpina Zhang & Chen, sp. nov.; Pseudostegana amnicola Zhang & Chen, sp. nov.; Pseudostegana amoena Zhang & Chen, sp. nov.; Pseudostegana mailangang Zhang & Chen, sp. nov.; Pseudostegana meiduo Zhang & Chen, sp. nov.; Pseudostegana meiji Zhang & Chen, sp. nov.; Pseudostegana mystica Zhang & Chen, sp. nov.; Pseudostegana stictiptrata Zhang & Chen, sp. nov.; Pseudostegana stigmatptera Zhang & Chen, sp. nov.; Pseudostegana ximalaya Zhang & Chen, sp. nov. and Pseudostegana zhuoma Zhang & Chen, sp. nov. A key to all Chinese Pseudostegana species based on morphological characters is provided. Two mitochondrial loci (COI and ND2) and one nuclear locus (28S rRNA) were sequenced for the Pseudostegana specimens, and Bayesian and RAxML concatenated analyses were run. Molecular species delimitation is performed using the distance-based automatic barcode gap discovery (ABGD) method. Molecular data support the morphological characteristics observed among these Chinese species and confirm the new species as being distinctly different.

Galianthe (Rubiaceae) is a neotropical genus comprising 50 species divided into two subgenera, Galianthe subgen. Galianthe, with 39 species and Galianthe subgen. Ebelia, with 11 species. The diagnostic features of the genus are: usually erect habit with xylopodium, distylous flowers arranged in lax thyrsoid inflorescences, bifid stigmas, 2-carpellate and longitudinally dehiscent fruits, with dehiscent valves or indehiscent mericarps, plump seeds or complanate with a wing-like strophiole, and pollen with double reticulum, rarely with a simple reticulum. This study focused on two species that were originally described under Diodia due to the occurrence of fruits indehiscent mericarps: Diodia palustris and D. spicata. In the present study, classical taxonomy is combined with molecular analyses. As a result, we propose that both Diodia species belong to Galianthe subgen. Ebelia. The molecular position within Galianthe, based on ITS and ETS sequences, has been supported by the following morphological characters: thyrsoid, spiciform or cymoidal inflorescences, bifid stigmas, pollen grains with a double reticulum, and indehiscent mericarps. However, both species, unlike the remainder of the genus Galianthe, have homostylous flowers, so the presence of this type of flower significantly modifies the generic concept. In this framework, a third homostylous species, Galianthe vasquezii, from the Andean region is also described. Until now, this species remained cryptic under specimens of Galianthe palustris It differs however from the latter by having longer calyx lobes, the presence of dispersed trichomes inside the corolla lobes (vs. glabrous), fruits that are acropetally dehiscent (vs. basipetally dehiscent), and its Andean geographical distribution (vs. Paranaense). Additionally, a lectotype has been chosen for Diodia palustris, Borreria pterophora has been placed under synonymy of Galianthe palustris, and Galianthe boliviana is reported for the first time from Peru. A key of all Galianthe species with indehiscent mericarps is also provided.
