Callainireinwardtia Savage (Diptera, Muscidae) is a Cyrtoneurininae of uncertain position: Systematics and description of a new species from Brazil Zool. Anz. (IF 1.4) Pub Date : 2024-02-28 Kirstern Lica Follmann Haseyama, Maria Carolina Romagna Boiarski, Elaine Della Giustina Soares, Silvio Shigueo Nihei, Claudio José Barros de Carvalho
Savage is a genus of Neotropical Cyrtoneurininae known from Savage, a species only known from six specimens collected in Costa Rica. Considering the combination of a bare anepimeron, metallic blue-green color, and the morphology of the post-abdomen, the original author proposed that the genus belongs to Reinwardtiini, whose taxa are considered to belong to Cyrtoneurininae or Reinwardtiinae in more

The nomenclature of the amphi-Atlantic mangrove oysters Zool. Anz. (IF 1.4) Pub Date : 2024-02-24 Philippe Bouchet, Serge Gofas, Daniele Salvi
An article published last year in this journal (Ferreira et al., 2023) advocated the use of the name (Dillwyn, 1817) for an amphi-Atlantic mangrove oyster. We challenge this terminology, which is not supported by the International Code of Zoological Nomenclature, and defend the status quo accepting the name (Lamarck, 1819).

Red snapper fish is one of the most economically important marine fish groups in the world with high morphological similarities. Currently, the taxonomy of snappers relies on external morphological characteristics and genetics (DNA barcoding). Relying solely on morphology for taxonomy might lead to invalid results, whereas the genetic approach is known to be costly and time-consuming. Therefore, this

The identification of native mangrove oyster species of the genus Crassostrea in Brazil is a recurring issue for specialists. Studies have recognized the presence of two species in the littoral zone: C. rhizophorae and C. gasar. However, other names may be used, such as C. mangle for C. rhizophorae and C. brasiliana or C. tulipa for C.gasar. As in most oyster taxonomic studies, their identification

Unleashing Abria Sørensen, 1932: New generic rank proposal for a false Venezuelan Cynorta Koch, 1839 (Opiliones: Cosmetidae) Zool. Anz. (IF 1.4) Pub Date : 2023-06-07 Osvaldo Villarreal, Miguel Medrano, Adriano B. Kury
A small group of species historically included in the genus Cynorta C.L. Koch, 1839 has been identified and described in this study. Based on a phylogenetic analysis using morphological data, we propose that these species be recognized as a non-monotypic genus, for which the available name Abria Sørensen, 1932 is used. Abria is newly diagnosed and its species illustrated, and its systematic position

Differential masculinization of the chelipeds in two simultaneously hermaphroditic Apseudes tanaidaceans (Crustacea: Malacostraca) Zool. Anz. (IF 1.4) Pub Date : 2023-06-01 Keiichi Kakui, Chizue Hiruta
Simultaneous hermaphrodites are uncommon in Malacostraca, having been reported only in Decapoda, Isopoda, and Tanaidacea. Sexual traits not directly related to reproduction, such as masculinization of chelipeds, have received little attention. This study demonstrated that the tanaidacean Apseudes nipponicus Shiino is simultaneously hermaphroditic; and investigated the allometry of chelipeds in two

Digestive system of the marine blood fluke, Aporocotyle simplex (Odhner, 1900) (Digenea: Aporocotylidae) with consideration of the digenean digestive morphology Zool. Anz. (IF 1.4) Pub Date : 2023-05-29 Larisa G. Poddubnaya, Willy Hemmingsen, Ken MacKenzie
This is the first study describing the ultrastructure of the digestive system of a member of the marine teleost-infecting aporocotylid lineage, Aporocotyle simplex (Odhner, 1900), a blood parasite of the long rough dab Hippoglossoides platessoides (Fabricus, 1780) from the Norwegian Sea, Norway. The presence of particular morphological characters of the extensive A. simplex foregut and the four caecal

Defining generic limits in Syndesini MacLeay, 1819 (Coleoptera: Lucanidae: Syndesinae) through taxonomy and geometric morphometrics Zool. Anz. (IF 1.4) Pub Date : 2023-05-26 Juan Sebastián D. Cáceres, Laura M. Pérez, Paschoal C. Grossi, Hugo Benitez
A comparative taxonomic study was performed between the Syndesini genera Syndesus MacLeay, 1819 and Psilodon Perty, 1830. Both taxa are redescribed, with the addition of more precise diagnostic traits, including the description of male and female genitalia. We provide comparative remarks to support the separation of both genera, with additional information obtained through the application of geometric

Distribution and noteworthy records of parasitic bugs genus Hesperoctenes (Hemiptera: Polyctenidae) associated with bats (Chiroptera) in Colombia Zool. Anz. (IF 1.4) Pub Date : 2023-05-16 Erika M. Ospina-Pérez, Daniela Velásquez-Guarín, Ingrith Y. Mejía-Fontecha, Paula A. Ossa-López, Camilo A. Llano Arias, Fredy A. Rivera-Páez, Héctor E. Ramírez-Chaves
The family Polyctenidae (Cimicoidea: Hemiptera) is a group of ectoparasites that has received very little attention from researchers. These bugs are typically associated with bats and are found primarily in tropical and subtropical regions worldwide. Polyctenidae consist of 32 species, which are divided into two subfamilies (Polycteninae and Hesperocteninae) and five genera (Adroctenes, Eoctenes, Hypoctenes

Taxonomic study of species of tribe Aphonoidini Gorochov, 2008 (Orthoptera: Oecanthidae) based on ovipositor morphology in China Zool. Anz. (IF 1.4) Pub Date : 2023-04-18 Qian Wu, Rong-Hua Guo, Li-Bin Ma
The tribe Aphonoidini was established by Gorochov in 2008 and includes 18 genera. There are currently ten species of this tribe in China. Because female crickets of this tribe are relatively similar in external morphology and cannot be easily distinguished from one another, we have used the morphology of the ovipositor in this study with the objective of evaluate this value in the identification of

Auditory system biophysics in a new species of false-leaf katydid (Tettigoniidae: Pseudophyllinae) supports a hypothesis of broadband ultrasound reception Zool. Anz. (IF 1.4) Pub Date : 2023-04-14 Charlie Woodrow, Fernando Montealegre-Z
The auditory system of the katydid is an established model system for studies of hearing, predator-prey interactions, and cochlea dynamics. The components peripheral to the ear substantially influence the hearing threshold, with an internal auditory trachea tuned to the calling song of conspecifics, and external pinnae capable of enhancing ultrasounds for predator detection. The trade-off between such

A geometric morphometrics and genetics characterization of Vanessa carye in an extreme elevational gradient in the Chilean Altiplano Zool. Anz. (IF 1.4) Pub Date : 2023-04-15 Scott Escobar-Suárez, Amado Villalobos-Leiva, Alejandra Fabres, Rodrigo Órdenes-Clavería, Franco Cruz-Jofré, David Laroze, Margarita Correa, Moisés A. Valladares, Juan Sebastián D. Cáceres, Hugo A. Benítez
The Western Painted Lady butterfly, Vanessa carye (Hüber, 1812), in addition to pre-senting an extensive distribution in South America, has been observed flying in the Chilean Alti-plano from the coast to the highlands, from 0 to 5200 m.a.s.l. and it is suggested that could be a migratory insect. Some animal species move from one place to another by migration searching for favorable conditions. Wings

DNA barcoding supports life stages of wrasse fish, Novaculichthys taeniourus (Family Labridae) in the Hurghada Red Sea, Egypt Zool. Anz. (IF 1.4) Pub Date : 2023-04-05 Moharam Adel Mohamed Afifi, Moustafa Sarhan, Hassan M.M. Khalaf-Allah, Ahmed Nasr Alabssawy, Mahmoud Mahrous M. Abbas, Fouad Abdel-Hamid, Mohamed Ahmed Mohamed El-Tabakh
Family Labridae considered diverse group of the fish that come in a variety of body forms, sizes, colors, and environments. Due to the great overlap between the species of this family, we find it very difficult to classify them using traditional methods. The goal of current study is to look at intra-specific development in Novaculichthys taeniourus, family Labridae. To assess whether the differences

Elucidating taxonomic problems of two closely related freshwater prawn lineages of the genus Macrobrachium (Caridea: Palaemonidae): A geometric morphometrics approach Zool. Anz. (IF 1.4) Pub Date : 2023-03-25 Caio S. Nogueira, Nícholas F. Camargo, João A.F. Pantaleão, Rogerio C. Costa
Macrobrachium amazonicum and Macrobrachium pantanalense are two closely related freshwater prawn species, the latter having been described from populations that were previously considered M. amazonicum. Distinguishing these two lineages from the available taxonomic description can be a complex task due to the morphological similarity of these organisms. In these cases, the investigation of morphological
