Recent phylogenetic studies have created a framework for our understanding of ectrichodiine evolutionary history, but no fossil species have been described. Ectrichodiella Fracker and Bruner, 1924, belongs to the earliest diverging lineage of Ectrichodiinae, and a better understanding of the morphology and biodiversity of this genus may provide insights into the early evolution of the subfamily. The genus is composed of two described species, Ectrichodiella minima (Valdés, 1910) and Ectrichodiella rafaeli (Gil-Santana and Coletto-Silva, 2005) from Cuba and Brazil, respectively. Here, four new species of Ectrichodiella are described, with three representing extant taxa known only from French Guiana (E. caballina, n. sp., E. nouraguensis, n. sp., and E. obscura, n. sp.), while the fourth is based on a Miocene Dominican amber fossil (Ectrichodiella electrina, n. sp.). Diagnoses, descriptions, habitus and detailed morphological images, an identification key, and a distribution map are provided. A cladistic analysis based on 45 morphological characters that includes the fossil species corroborates the monophyly of Ectrichodiella, but the relationship of the fossil species to the five extant species remains ambiguous. Nevertheless, this phylogenetic placement makes Ectrichodiella electrina, a valuable fossil calibration for future divergence dating analyses, despite its relatively young age.","PeriodicalId":55527,"journal":{"name":"American Museum Novitates","volume":"12 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142196791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we describe three new species of Paravandellia based on photomicroscopy, cleared and stained specimens, and µCT imagery. We also reevaluate diagnostic character states for Paravandellia and Paracanthopoma, propose a new character to diagnose Paravandellia, and present our discovery of a possible type specimen of Parabranchioica teaguei and additional non-type specimens of Branchioica bertoni, junior synonyms of Parav. oxyptera. Based on these observations, we confirm Parav. alleynei and a recent newly described species of Paracanthopoma as members of a rediagnosed, putatively monophyletic Paravandellia, increasing its richness from two to seven species.

A wealth of vertebrate and invertebrate forms has previously been recorded from this deposit, including fish, annelids, and several arthropods. To expand the record of Bear Gulch marine arthropods, a new enigmatic, possibly blind euchelicerate, Titanoprosoma edgecombei, gen. et sp. nov., is described. The new euchelicerate taxon displays a hypertrophied, ovate, and structureless prosoma—a morphology unique among marine euchelicerates. We explore how the large prosoma and lack of ocular structures reflect possible adaptations to an infaunal, burrowing lifestyle. This species represents the fourth euchelicerate genus described from the Bear Gulch Limestone, further highlighting the impressive disparity of marine arthropods preserved in the deposit. The addition of novel invertebrate forms found in previously unknown museum material suggests that the Bear Gulch Limestone likely houses a still undocumented diversity of Carboniferous arthropods.","PeriodicalId":55527,"journal":{"name":"American Museum Novitates","volume":"5 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139666442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is analogous to the condition in the dolichopodid Melanderia Aldrich, but there it is not sexually dimorphic. The structures are doubtfully used in male-male aggression or in postcopulatory mate guarding.

In the present contribution, a new euscorpiid scorpion with a distinctive morphology, Euscorpius olympus, sp. nov., is described from an isolated population in the foothills of Mount Olympus. This new species raises the number of species in the genus Euscorpius Thorell, 1876, to 74, in Greece to 32, and in the vicinity of Mount Olympus, to three.
