Despite this attention, its phylogenetic position and internal intergeneric relationships remain contentious. This study sequenced complete mitochondrial genomes of four xenophorid species—<em>Stellaria solaris</em>, <em>Aspidophoreas chinensis</em>, <em>Xenophora conchyliophora</em>, and <em>Xenophora cerea</em>—to resolve the phylogeny and systematic placement of this family. Comparative analyses revealed high mitochondrial genome similarity among these species in structure, size, gene order, and nucleotide composition. The mitochondrial genomes exhibited significant nucleotide variation among protein-coding genes. Selection pressure analyses indicate purifying selection across all PCGs, with <em>atp8</em> showing the weakest evolutionary constraint. This suggests that <em>atp8</em> may be subject to stronger selective pressures, potentially reflecting substantial energy demands associated with xenophorids' unique attachment ecology. Phylogenetic reconstruction supported two major clades within Stromboidea: Clade I included Strombidae + (Rostellariidae + Seraphsidae) and Clade II comprised Xenophoridae + (Struthiolariidae + Aporrhaidae). Internally, Xenophoridae exhibited a strongly supported clade (<em>Onustus</em> + <em>Stellaria</em>) + <em>Aspidophoreas</em> that aligned with morphological classifications and features with reduced/absent object attachment, clearly separating it from <em>Xenophora</em>. Notably, <em>Xenophora japonica</em> did not form a monophyletic group with the sister taxa <em>X. conchyliophora</em> and <em>X. cerea</em>. Morphological and molecular evidence collectively indicate that the current taxonomy of <em>Xenophora</em> requires revision.</div></div>","PeriodicalId":49332,"journal":{"name":"Zoologischer Anzeiger","volume":"321 ","pages":"Pages 125-135"},"PeriodicalIF":1.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145977961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, molecular data repeatedly show convergence and underestimation of species diversity due, in part, to the superficiality of morphological diagnoses based on external characters. In contrast, the internal male genitalia have proved to be useful for assessing species diversity, but remain poorly studied because of their complexity and variation. Nevertheless, interest in internal male genitalia has recently increased as they provide an important number of additional characters useful to identify species for which the traditional sets of characters are insufficient. To date, the genitalia of 105 species from 55 genera belonging to 13 families are known, but comparative approaches across taxa are difficult due to different terminology. Our aim is to propose a nomenclature for the genitalia of Diapheromerini that can be used for standardized descriptions as well as for the postulation of homology assessments. We focused on <em>Pseudosermyle</em>, the most diverse genus in North America, which exhibits many different shapes: phasmid appearance and genitalia. We reviewed the literature on internal male genitalia in Phasmatodea and examined it, as well as the external male genitalia in different Diapheromerini species. This is the first attempt to use these structures to identify orthologues as potential homologues within Phasmatodea. We hope that our study will improve communication and promote systematic analysis of internal and external male genitalia, at least in Diapheromerini.</div></div>","PeriodicalId":49332,"journal":{"name":"Zoologischer Anzeiger","volume":"321 ","pages":"Pages 179-197"},"PeriodicalIF":1.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145977966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, this research aimed to ultrastructurally characterize the antennal sensilla of males and females of <em>T. arnobia</em>. For the characterization of the structural morphology of the sensilla in the antennae of females and males of <em>T. arnobia</em>, scanning electron microscopy was used.

I digitized 71 landmarks on 151 adult specimens representing six <em>Eligmodontia</em> species and one outgroup (<em>Calomys callosus</em>) from 54 localities across South America, analyzing patterns using an ANOVA framework based on residual randomization in a permutation procedure (RRPP), allometric regressions, principal component analysis (PCA), and clustering methods.

Phylogenetic congruence was limited, with morphological clustering diverging from molecular relationships. Larger crania exhibited typical mammalian allometric scaling patterns with elongated rostra (faces) and contracted braincases. Climate and geography significantly influenced cranial variation, with northern taxa differing morphologically from central-southern species in tympanic bulla inflation, corresponding to distinct spatially structured climatic regimes of seasonal versus year-round precipitation patterns. In addition to bulla hypertrophy, ecological adaptations also included nasal elongation and narrowing in more arid habitats, plus increased cranial robustness in tougher soils and for high bite-force diets.
