The Cactaceae species <i>Xiquexique gounellei</i> and <i>Xiquexique tuberculatus</i> present different habitat preferences in the Brazilian Caatinga, however, across their distributions, some populations occur sympatrically and some individuals showed vegetative characteristics intermediate between these two species, suggesting a hybrid zone. These individuals also clearly did not belong to either of the two species, leading us to suppose that they could be hybrids, named as <i>X.</i> × <i>heptagonus</i>. Taking into account this assumption, we used a series of protocols to compare the floral attributes and signals, and floral biology displayed by the putative hybrid with those of its parents. The results showed that the flowers of the hybrid are morphologically intermediate to those of their parents. The colour of the external elements of the perianth is transgressive, and the white colour of the internal perianth-segments is shared between the three taxa. Scent analyses showed that <i>X.</i> × <i>heptagonus</i> has a scent profile that is intermediate to those of its parents, with only a few compounds indicating a transgressive phenotype. Both taxa of <i>Xiquexique</i> received visits from nectarivorous bats (Glossophaginae and Lonchophyllinae) and from the hawkmoths <i>Agrius cingulata</i> and <i>Erinnyis ello</i>. Our results reinforce the existence of this hybrid in the genus <i>Xiquexique</i> being derived from the possible parent species present.

Whereas cheilostome bryozoans are well-studied in these latitudes, ctenostomes remain highly neglected. Large ctenostomes are easily recognized by their lack of calcified skeletons, but this lack also renders them difficult and tedious to identify. As a result, histology and reconstructions of internal soft tissues are required to classify this group of bryozoans. Thanks to the availability of new specimens from Terra Nova Bay, a detailed analysis of growth form, gut morphology and tentacle number of two colonies, initially ascribed to the ctenostome bryozoan genus <i>Alcyonidum</i> Lamouroux, 1813, turned out to be a new species, <i>Alcyonidium kuklinskii</i> sp. nov., which we described in this study. These specimens were also barcoded (COI) and sequences compared to available ones. Together with the new species described here, a total of ten species of <i>Alcyonidium</i> is now known for the Southern Ocean, accounting for one eighth of the entire genus diversity. All Southern Ocean species appear to be endemic. In order to speed the identification of the Antarctic <i>Alcyonidium</i> species, we provide an identification key and a distribution map of all type species. In brief, colony morphology, zooidal size and, in particular tentacle number represent the most suitable characters for identifying species within this genus.</p>","PeriodicalId":54666,"journal":{"name":"Organisms Diversity & Evolution","volume":"337 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138553447","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, malacologists have been puzzled by the taxonomic position and species validity of certain species, particularly those described solely based on conchological characteristics. The genus <i>Lepidodesma</i> is one such group. Here, we integrate shell morphology, soft-body anatomy, and molecular phylogeny to delimit the species validity of <i>Lepidodesma aligera</i> (Heude in Conchyliologie Fluviatile de la Provoince de Nanking 3:17–24, 1877) and <i>Lepidodesma languilati</i> (Heude in Journal De Conchyliologie 22:112–118, 1874). Comparative morphology reveals that <i>L</i>. <i>aligera</i> can be distinguished from <i>L</i>. <i>languilati</i> by its higher post-dorsal wing covered with scattered nodules, as well as differences in the incurrent aperture, excurrent aperture, and gill. Additionally, the average genetic distance based on DNA barcodes (COI) between both species is 4.0%. Integrative taxonomy supports the distinct species of <i>L. aligera</i>, rather than synonymy for <i>L. languilati</i>. Mitochondrial phylogenomic analyses confirm four monophyletic groups (Ambleminae + (Gonideinae + (Unioninae + Parreysiinae))) within the family Unionidae. <i>L. aligera</i> and <i>L. languilati</i> have a well-supported sister-group relationship and form a basal clade splitting from the rest of Unioninae. Therefore, the genus <i>Lepidodesma</i> should be classified as Lepidodesmini in Unioninae. The molecular clock with fossil calibration indicates that <i>Lepidodesma</i> originated in the Early Cretaceous (~121.30 Mya, 95% HPD = 90.37–156.54 Mya) and diverged in the Middle Neogene (~12.94 Mya, 95% HPD = 6.72–22.13 Mya). This study firstly provides anatomical features and molecular data for <i>L. aligera</i> and demonstrates the species validity and the systematic position of <i>Lepidodesma</i> taxa, which enrich our understanding of this rare group and facilitate its management and conservation.</p>","PeriodicalId":54666,"journal":{"name":"Organisms Diversity & Evolution","volume":"913 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2023-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138531111","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}

Five known species are recorded from Cuba: Kytorhynchus microstylus , Ceratopera paragracilis , Trigonostomum armatum , T . franki , and T . vanmecheleni . Neokytorhynchus pacificus is recorded for the first time in the Atlantic (Lanzarote). For one species, a new genus is erected to be included in a new family. A new genus and thirteen new species from Cuba and three new species from Panama are described. The new species are mainly distinguished from their congeners by the specific morphology of the copulatory structures. The new taxa are discussed in the context of a new phylogenetic analysis of Dalytyphloplanida. This analysis includes sequences of 238 species, 14 of which were sequenced for the first time. The phylogenetic analysis and the detailed morphology suggest that K . microstylus may constitute a complex of cryptic species. The internal phylogenetic relationships of Trigonostomum and Promesostoma were separately analysed to include new sequence data of the mitochondrial cox1 gene. These genera are shown to consist of several diagnosable clades, concurring with the results of early morphological studies of these taxa. Morphological and molecular data support the notion that Trigonostomum sinensis is a junior synonym of T . vanmecheleni , and we therefore propose their synonymisation. A new family is erected, Schockaertiidae fam. n. , to include a monophyletic clade of neodalyellids with a pharynx rosulatus and a copulatory bulb devoid of hard structures ( Schockaertia aprostatica gen. n. sp. n. and Einarella argillophyla ). We propose a new classification into families of Thalassotyphloplanida, which envolves elevating the status of Adenorhynchinae to family level (Adenorhynchidae status novus ). All previously recognised thalassotyphloplanid families are recovered as monophyletic (Kytorhynchidae, Byrsophlebidae, Promesostomidae, and Trigonostomidae). No support was found for the previously described subfamilies, except Paramesostominae, and we, therefore, propose to suppress these taxa.","PeriodicalId":54666,"journal":{"name":"Organisms Diversity & Evolution","volume":"278 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135413423","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}

The new species, Alismobates piratus sp. n., shows considerable COI and 18S rRNA gene sequence divergences and although morphometric analyses indicate considerable variation between the taxa, no distinguishing morphological feature could be detected. The extreme intertidal environment is suggested to be responsible for the observed morphological stasis of the two species and vicariance is supposed to be responsible for their speciation. Alismobates piratus sp. n. was found on Hispaniola, Guadeloupe, Barbados and Curaçao indicating a predominant distribution on the Greater and Lesser Antilles, whereas the occurrence of A. inexpectatus is primarily restricted to Central America, the northern Caribbean and the Greater Antilles. Haplotype network analyses indicate distinct geographic structuring and the absence of recent gene flow among the Antillean A. piratus sp. n. populations. Central American and Antillean populations of A. inexpectatus show similar patterns but populations from Bermuda and the Bahamas are characterized by a common origin and subsequent expansion. Genetic landscape analysis demonstrates that vast stretches of open ocean, like the Caribbean Basin and the Western Atlantic, act as rather effective barriers, whereas the continuous continental coastline of Central and North America may facilitate dispersal. Genetic data also indicates that the Gulf Stream plays an important role for the biogeography of intertidal oribatid mites as it may be responsible for the strong link between Central and North American populations as well as for the colonization of Bermuda.","PeriodicalId":54666,"journal":{"name":"Organisms Diversity & Evolution","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135200388","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}
