The genus Xenoxybelis contains two species, X. argenteus and X. boulengeri, characterized by semi-arboreal habits and an extremely thin rostral area, classified in the subfamily Xenodontinae (Colubridae). Xenoxybelis boulengeri is considered a rare species and is poorly represented in scientific collections. Its external morphology is known only from the original description and seven other specimens. In this study, twenty additional specimens were examined from the Brazilian states of Acre, Amazonas and Rondônia. Variation in meristic and morphometric characters are described, and new characters are incorporated in a revised diagnosis of the species. Illustrations and a description of the hemipenes of X. boulengeri are presented for the first time. Analysis of morphological and molecular characters permit allocation of Xenoxybelis to the tribe Phylodryadini, together with Ditaxodon, Philodryas, Pseudablabes and Tropidodryas.

Gonatopus mariae Martins, Lara, Perioto & Olmi, 2015, described from the state of São Paulo, is recorded for the first time in the state of Espírito Santo, Brazil, representing the first record of the genus and species from the state. The specimen was collected with a Malaise Dossel trap and deposited at the Entomological Collection of the Universidade Federal do Espírito Santo (Brazil). A diagnosis and illustration of this species are presented  demonstrating morphological variation of the type material. A distribution map is also provided. Gonatopus mariae is a rare species and its distribution is probably restricted to the southeastern region of Brazil.

The wolf spider genus Alopecosa Simon, 1885 contains 152 species (WSC 2017), 30 of which are poorly described. Alopecosa krynickii (Thorell, 1875) is one of the least known European species of wolf spiders, of which the single male was collected in November, 1860 (Logunov 2013a: fig. 3). The original description of the species was made by Thorell (1875a, b), without illustrations. Since then no studies on A. krynickii based on new material have been published. Recently, Logunov (2013a) redescribed this species on the basis of its holotype. This redescription allowed me to identify A. krynickii from newly collected material from the Crimea. The aim of the present paper is to redescribe the rare species Alopecosa krynickii, based on both sexes and to describe the female for the first time.

The bee genus Brachymelecta Linsley, 1939 has until now been represented by a single specimen, which has puzzled melittologists since its original description as Melecta? mucida Cresson, 1879. Through detailed morphological comparison and images, we show that the holotype is no more than an unusual specimen of a widespread species, most recently known as Xeromelecta californica (Cresson, 1878). We demonstrate that the diagnostic generic features for Brachymelecta fall within the range of morphological variation observed within X. californica. Although the names Brachymelecta and Xeromelecta Linsley, 1939 were published simultaneously, the former was proposed as a genus whereas the latter was proposed as a subgenus of Melecta Latreille, 1802. Thus, the following synonymies are proposed: Xeromelecta syn. nov. under Brachymelecta (since precedence must be given to the name that originally had the higher taxonomic rank) and M.? mucida syn. nov. under B. californica. Additionally, we present updated taxon concepts for and an identification key to the six known species now in Brachymelecta — B. alayoi (Michener, 1988), B. californica, B. haitensis (Michener, 1948), B. interrupta (Cresson, 1872), B. larreae (Cockerell, 1900), and B. tibialis (Fabricius, 1793) — along with redescriptions and a diagnosis for the genus. The male of B. alayoi and females of B. haitensis and B. tibialis are described for the first time. Furthermore, a phylogeny based on combined molecular and morphological data is proposed for Brachymelecta, and the evolution of the genus is explored in a historical biogeographic context.

Dasypoda bees are host-specialized solitary species distributed in the Palaearctic Region. In the framework of a global revision of this genus, comprehensive descriptions of three rare species (D. tibialis Morawitz, D. vulpecula Lebedev and D. iberica Warncke) are presented. The detailed morphology of the D. tibialis male and both sexes of D. vulpecula are given for the first time after a very partial original description. The females of D. tibialis and D. iberica are described for the first time and additional morphological characters of the male of D. iberica are provided. The lectotype of Dasypoda tibialis is designated. Host-plants and new localities are also presented.

We describe two species from the genus Triconia Böttger-Schnack, 1999 in the family Oncaeidae from the northeastern equatorial Pacific, both belonging to the conifera-subgroup. Both sexes of T. derivata (Heron & Bradford-Grieve, 1995) are redescribed, including morphological features not noted in earlier descriptions, such as the posterior face of the labrum. Specimens of T. derivata from the northeastern equatorial Pacific differ slightly from the original descriptions in some morphometric characters, and their differentiation from T. furcula (Farran, 1936), which is closely related, is summarized. The male of T. hirsuta Wi, Böttger-Schnack & Soh, 2010 is described for the first time and the morphology of the female is redescribed. The female holotype of T. hirsuta from Korean waters is reexamined and discrepancies between text and figures in the original description regarding the endopodal spine lengths on swimming leg 2 are clarified. A revised version of the respective part of the original figure is included in the present paper. An indication of the variation in endopodal spine lengths on swimming legs 2 to 4 is provided for both sexes of the two species. It is pointed out that morphometric characters required for unequivocal identification of species of the conifera-subgroup are still not sufficiently well defined. The records of T. derivata and T. hirsuta to date are summarized and indicate a wide zoogeographical distribution of the former 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.

Records of 46 Psychodidae (Sycoracinae 1, Trichomyiinae 1, Psychodinae 44) species/subspecies are presented in this paper based on specimens collected by sweep-netting in Azerbaijan and Georgia in 2019. Nine species are recorded for the first time since their original description; 12 species are new for Transcaucasia; 22 species are new for Azerbaijan; and 17 species are new for Georgia. Saraiella ressli montana Ježek, 1990 is proposed as a synonym of S. ressli Wagner, 1983, syn. nov. Knowledge of some aspects of the ecology and biogeography of selected (especially rare) species has been expanded and a clear pattern was found in species richness, rare species, and new records in relation to land use, habitat diversity, and preservation of the environment surrounding the sampling site.
