Diversity and distribution of intertidal Microporella (Bryozoa: Cheilostomatida) from California
(2024)
Seven species of the cheilostome bryozoan genus Microporella were identified across 15 rocky intertidal sites spanning 940 km of the California coast, from Mill Creek in the Montereyan Pacific Transition Region north to Point Saint George in the Mendocinian Region. Colonies of Microporella were found encrusting boulders and mollusc shells. Among these species, three are new to science, namely Microporella dentata Chowdhury & Di Martino sp. nov., M. pauciperforata Chowdhury & Di Martino sp. nov. and M. rota Chowdhury & Di Martino sp. nov. Three other species, M. californica, M. setiformis, and M. umbonata have previously been recorded from other localities in California. Finally, Microporella neocribroides, originally described from off Kodiak Island, Alaska, and subsequently found in Hokkaido, Japan, was recorded in California for the first time. An additional new species, M. similis Chowdhury & Di Martino sp. nov., was identified through the re-examination of museum material previously attributed to M. cribrosa and M. californica. These newly acquired data allowed for a more comprehensive examination of the distribution of species, intraspecific variability, and potential predator-induced teratologies in certain species, thanks to the availability of numerous colonies from various sites and the re-examination of museum records. Altogether, this study increases the known Recent diversity of Microporella in California’s waters to a total of 18 species.

Angel sharks (Squatina spp. Duméril, 1805) are a group of coastal benthic sharks distributed worldwide, currently including threatened and understudied species. Two species are formally described along the East Pacific coast, the California angel shark S. californica Ayres, 1859 and the Chilean angel shark S. armata (Philippi, 1887). The latter species occurs in the southeastern Pacific and has historically been understudied. Additionally, the original description of S. armata lacks sufficient data to confidently identify individuals of this species compared to modern descriptions, and no type specimen is currently available to ensure specimen identification. Detailed morphological descriptions for identifying species are an essential resource for solving taxonomic issues in groups of morphologically similar species and to promote the conservation of critically endangered species. Therefore, a neotype from the type locality is here designated for S. armata, and a detailed and standardized morphological characterization based on modern taxonomic works is provided. This work contributes in improving the knowledge on the Chilean angel shark taxonomy and provides an improved frame of reference for identifying angel sharks in the East Pacific, especially in areas where species may occur in sympatry.

Zebragryllus Desutter-Grandcolas & Cadena-Castañeda, 2014 is a Neotropical genus of field crickets that inhabits the leaf litter of the Amazon rainforest. The genus has six species and is characterized by the distinct ‘zebra’ pattern displayed by some of them. The species are recorded in French Guiana, Peru, and Colombia. Here, we describe two new species of the genus from the Brazilian Amazon rainforest, the first record of the genus for Brazil. We expand the records of Z. guianensis Desutter-Grandcolas, 2014 and Z. nouragui Desutter-Grandcolas, 2014 to Brazil. We also describe but do not name two females corresponding to two new species, provide an up-to-date key for species of Zebragryllus, and discuss the potential distribution for the genus.

Two new endemic genera of Therevinae are described from Madagascar. Rinhatiana gen. nov. contains three new species (R. arctifestuca gen. et sp. nov., R. cracentis gen. et sp. nov. and R. latifestuca gen. et sp. nov.) as well as R. distincta (Lyneborg, 1976) comb. nov., which is transferred from Stenopomyia Lyneborg, 1976. Tianarinha gen. nov. is described containing two new species, T. goodmani gen. et sp. nov. and T. micet gen. et sp. nov. All species are diagnosed and figured along with distribution data.

The cosmopolitan pipunculid genus Dasydorylas Skevington, 2001 includes just a few species from the Neotropical Region and is completely unknown to Colombia. Three new species of Dasydorylas are described from protected areas and conflict territories of limited access in Colombia, namely Dasydorylas colombiensis sp. nov. (type locality: Santuario de Fauna y Flora Iguaque, Boyacá), D. gibber sp. nov. (type locality: Santuario de Fauna y Flora Iguaque, Boyacá), and D. santainesensis sp. nov. (type locality: Páramo de Santa Inés, Belmira, Antioquia). Diagnoses, illustrations and distributional data of the new species are presented. Dasydorylas nigellus (Rafael, 1991) is recorded for the first time from Colombia and its amended diagnosis is provided. An identification key to males of all Neotropical species is presented. With this paper, the number of Neotropical species of Dasydorylas is increased from six to nine.

The cleptoparasitic bee genus Triepeolus Robertson, 1901 (Hymenoptera: Apidae) is revised for species occurring in South America. A total of nine species are confirmed from the continent, of which T. tuberculifer Onuferko, Rightmyer & Roig-Alsina sp. nov. is newly described. Four new synonymies are proposed: T. aguilari Moure, 1955 syn. nov. and T. megadelphus Cockerell, 1914 syn. nov. under T. buchwaldi (Friese, 1908); T. bilineatus Cockerell, 1949 syn. nov. under T. flavipennis (Friese, 1916); and Epeolus merus Brèthes, 1909 syn. nov. under T. nemoralis (Holmberg, 1886). Males of T. alvarengai Moure, 1955 and T. rufotegularis (Ashmead, 1900) and females of T. atoconganus Moure, 1955 and T. cecilyae Packer, 2016 are described for the first time. Lectotypes are designated for the following (all originally described under Epeolus Latreille, 1802 but now recognized as Triepeolus): E. buchwaldi, E. flavipennis, E. osiriformis Schrottky, 1910 and its junior synonym E. luteipes Friese, 1916, and E. rufotegularis. Diagnoses and complete descriptions/redescriptions are provided for all species, along with a fully illustrated dichotomous identification key (with Portuguese and Spanish versions available as supplementary material) to distinguish them based on external morphological features. Additionally, known collection records and information about the ecology of the treated species are presented.

Two new species of aulacid wasps, Pristaulacus iuliae Turrisi & Nobile sp. nov. from South India (Karnataka) and Pristaulacus ninae sp. nov. from Peninsular Malaysia (Pahang), are described, figured and compared with most related species. Based on the present addition, the Indomalayan area currently includes 27 species of Pristaulacus Kieffer out of 61 known from the whole Oriental Region, which is however a largely underestimated number. An identification key to species and an updated checklist of Pristaulacus occurring in the Indomalayan area are provided.

In this study, I describe two new species of Macrobiotus based on morphological data collected through light and scanning electron microscopy. Both species are accompanied by DNA sequences from four commonly used molecular markers (18S rDNA, 28S rDNA, ITS-2, and COI). Macrobiotus ovovittatus sp. nov. was discovered in Greenland and can be distinguished from similar taxa of Macrobiotus by its continuous, solid, and clearly wrinkled egg surface, adorned with sparse, very small and irregularly spaced pores. Additionally, the terminal discs of egg processes are covered in multiple light-refracting dots, resembling crocheted napkins. Macrobiotus mileri sp. nov. was found in Israel and is characterized by unique pore arrangements in its body cuticle, expressed in two distinct animal forms: (i) forma porata with large pores arranged in five distinct patches and (ii) forma aporata with single, almost undetectable pores. It also features weakly defined convex terminal discs with smooth edges. Furthermore, the phylogenetic analyses conducted in this study offer the most updated phylogeny of superclade I within the family Macrobiotidae. This facilitates additional discussion concerning the interrelationships among species within the genus Macrobiotus and the circumscription of species groups within it.
