Benchmarking in taxonomy is viewed both as establishing a specimen as a standard of reference and as a process for optimizing that process. Here, it is founded on vision theory that recognition of specimens, as for all objects, is personal to the obs...
In Yucatán state, Mexico, Triatoma dimidiata (Latreille, 1811) is the primary vector of Trypanosoma cruzi, the parasite that causes Chagas disease. The vector population presents diverse forms and colorations. Therefore, this study was designe...
The Philippines and the Papuan archipelagos harbor a vast diversity of pygmy grasshoppers, including the pygmy devils of the genera Xistra and Tegotettix, as well as visually similar taxa reviewed in this study. A new tribe, two new genera, a new sub...
Heliaster has long been considered to comprise seven nominal species of starfish distributed across the Eastern Pacific, from Baja California (Mexico) southward to central Chile. Along the southeastern Pacific coast, three taxa have been traditionall...
Based on external morphology, genital anatomy, and a fragment of the mitochondrial 16S rRNA gene, we identified two veronicellid slug species from Chiapas, Mexico: Simrothula prismatica (Simroth, 1914) and Diplosolenodes occidentalis (Guilding, 1824)...
A remarkable new pholcid spider species is described from the Democratic Republic of the Congo: Smeringopina polychila sp. nov. The male is distinguished by a unique and previously undocumented structure, here termed the “parachila”, whic...
A new species of Choreutidae, Tebenna acanthophallus sp. nov., from the Huasco Province, Chile, is described. Diagnostic characters, photographs of adults and illustrations of wing venation and genital structures are provided. The new species is supp...
The Neotropical region is recognized as the center of diversification of Phalangopsidae. The true extent of this diversity, however, remains understudied, reinforcing the need for further taxonomic investigations. In this study, we describe Igatuia c...
The recent update to the list of European herpetofauna species, published in 2020, includes 206 non-avian reptile species. The steppe ribbon racer, Psammophis lineolatus, is a snake species widely distributed across the deserts and semi-deserts of Ce...
