The Order Polycladida comprises a diverse yet understudied group of free-living flatworms, traditionally divided into Cotylea and Acotylea based on the presence or absence of a ventral adhesive organ known as a cotyl. Species identification, particul...

Mascagnia (Malpighiaceae) is the lianescent genus with the most convoluted taxonomic history and polyphyly of Malpighiaceae, formerly comprising eight unrelated accepted genera and over 300 species. This genus currently encompasses 48 accepted Neotro...

Tetrigidae is a caeliferan family of Orthoptera constituting a diverse and relatively ancient lineage of small Orthopterans, which has its greatest diversity in tropical and subtropical areas. However, to date, few studies have been conducted on the...

In specific altitude ranges, biotic and abiotic factors can impact vector mosquitoes’ adaptation capacity, affecting their population differentiation. This study analyses if there exist morphological and genetic differences in four Anopheles (K...

Tabanid species of the Andean genus Agelanius Rondani are revised herein based on an examination of the external morphology of the type material of ten species and specimens from Argentina and Chile. A new species, A. augustus sp. nov., is described,...

In this paper, Nanocnide simingshanensis is described as a new species based on morphological and molecular analyses, and its taxonomic relationships are discussed. The new species is currently known only from the Siming Mountain region of Yuyao Coun...

The genera: Lerniana Delicado et Hauffe, 2022, Trichonia Schütt, 1980, and two clades (“Radomaniola” elongata Radoman, 1973, and an unnamed clade referred to as “Radomaniola” sp. 1, sp. 2) whose assignment to any genus re...

Despite being the subgenus with the highest number of species within Chimarra Stephens, 1829 in Brazil, information about Chimarra (Curgia) Walker, 1980 is scarce in the Brazilian semi-arid region. Beyond the discussion about the quantity of species...

I suggest two ways to make taxonomic diagnoses more useful: they should state overtly (1) what taxa the new one is diagnosed against, I term this the reference group; and (2) how to identify the reference group from others in the higher-level group t...

The genus Raiamas currently comprises 18 valid species, only 2 of which occur in Asia; the remaining 16 are endemic to Africa. Raiamas harmandi was originally described by Sauvage in 1880 as Bola harmandi, which is distributed in the Great Lakes, Cam...

Woodcreepers (Dendrocolaptinae) constitute a subfamily of Neotropical passerines currently recognized as a monophyletic group within Furnariidae. Although Furnariidae is one of the most diverse avian families in the Neotropics, cytogenetic data remai...

Acidobacteriota are difficult to cultivate but pervasively and copiously distributed across nearly all ecosystems, especially soils, such as agricultural, peat, arctic tundra and metal-contaminated soils. Most of the currently available isolates are...

This study presents a comprehensive taxonomic revision of the genus Dissomphalus Ashmead (Hymenoptera, Bethylidae) in the southwestern Pacific, focusing on specimens from Fiji and the Solomon Islands. Dissomphalus is the most species-rich genus withi...

The Desmodium group is one of the three groups in the tribe Desmodieae distinguished by their lomentaceous fruits, trifoliolate leaves, presence of stipels, and hooked hairs. Due to recent generic circumscription in the Desmodium group, a taxonomic s...

The leafhopper genus Renonus is one of the rarest genera in the leafhopper tribe Athysanini. The Mexican endemic monotypic species, Renonus rubraviridis DeLong, is historically known from few localities, and since the original description, no additio...

Two new miniature tetra species of the genus Priocharax Weitzman and Vari 1987 are described, raising the known species diversity to twelve. Priocharax is characterized by several paedomorphic features such as reductions in the laterosensory system,...

This study on Mygalomorphs from Ecuador revealed an amazing unknown diversity, including the first record of the families Actinopodidae and Halonoproctidae. Here, 16 new species and one new genus are described in five families: in Actinopodidae, Acti...

Among European colubroids, scale sensilla—mechanoreceptors present in the head integument—are more expressed in natricids. The presence of protruded sensilla, observable with the naked eye, is found in the cephalic shields of all species...
