Specific geographic records were studied using Hovenkamp’s protocol (barrier biogeography). Leptohyphes was recovered as a monophyletic group. The most ancient disjunction found in Leptohyphes separated Tepui-area from the rest of the Americas. Other interesting vicariant events were found, including the separation of eastern Atlantic mountains (Mata Atlantica) from the Andes; oriental and occidental slopes of the Andes; northern from central Andes; and northern Andes from Central and North America. An ancient tropical South American origin for the genus is supported, with a more recent diversification due to Andean orogeny. Clades and terminals reaching North America include few independent events of more recent range expansions.","PeriodicalId":54975,"journal":{"name":"Insect Systematics & Evolution","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2021-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42580121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Not surprisingly, when a particular species assemblage has been revised, the number of species in that group increases significantly. Here, we revise the New Caledonian endemic genus Taophila Heller, 1916, the best studied in this fauna and currently known to include eleven species, one in the subgenus Jolivetiana Gómez-Zurita & Cardoso, 2014, and ten in the nominal subgenus. The analysis of morphological differences in a large sample of Taophila and the validation of the resulting species hypotheses in an integrative fashion based on a phylogenetic analysis of partial mtDNA sequences (cox1 and rrnS) resulted in the addition of eleven more taxa. Taxonomic splits mainly reinterpreted the previous observation of mtDNA paraphyly affecting T. subsericea Heller, 1916, shown to represent a complex of species mostly distinguishable by diagnostic differences among females. The new species described are: T. bituberculata n. sp., T. carinata n. sp., T. dapportoi n. sp., T. davincii n. sp., T. draco n. sp., T. goa n. sp., T. hackae n. sp., T. samuelsoni n. sp., T. sideralis n. sp., T. taaluny n. sp. and T. wanati n. sp. These additions and the synonymy T. subsericea Heller = Stethotes mandjeliae Jolivet, Verma & Mille, 2010 n. syn., bring to 21 the total number of species in Taophila. Moreover, we also found the first evidence of mtDNA introgression between species of New Caledonian Eumolpinae, resulting from putative recent hybridization of T. subsericea and T. dapportoi where these species coexist. We describe a model incorporating the mtDNA genealogy of T. subsericea about the conditions that may have favored the secondary geographic encounter required for the hybridization of these species.","PeriodicalId":54975,"journal":{"name":"Insect Systematics & Evolution","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2021-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42467220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To explore the evolution of cocoon loss within Formicidae, we perform an ancestral state reconstruction of cocooned pupae across a genus-level phylogeny and use a sister clade analysis to determine the impact of cocoon evolution on ant speciation. Then, we fit models of correlated evolution between cocoon status and several other organismal traits. We find that the re-emergence of cocoons is rare and that “naked” lineages display an increased rate of speciation in 5 out of 9 sister group comparisons. Models of correlated evolution with cocoon status were favored for metapleural gland and worker polymorphism. Metapleural gland favored rates of evolution were inconclusive, while worker polymorphism displayed a higher transition rate towards polymorphism coupled with cocoon loss. These results suggest that cocoon loss may allow for other complex traits to develop and may represent a novel example of relaxed selection.","PeriodicalId":54975,"journal":{"name":"Insect Systematics & Evolution","volume":"1 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2021-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41771815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A taxonomic revision and a morphological phylogenetic analysis were carried out to test species limits and to propose a hypothesis of evolutionary relationships. As a result of the phylogenetic analysis, Acanthischium is characterized on its external morphology by the elongate postocular region, posterior margin of the pronotum with spines, ventral surface of protrochanter with apical and basal protuberances, profemur wider than mesofemur, and protibia strongly curved. After the taxonomic revision we propose nine valid species, taking into consideration characters of external morphology, male and female genitalia, and color patterns: Acanthischium dimidiatum Stål, 1859 stat. rev.; Acanthischium flaviceps Stål, 1872 stat. rev.; Acanthischium haglundi Stål, 1866; Acanthischium kuna sp. nov. from Panama and Colombia; Acanthischium maculatum Amyot & Serville, 1843; Acanthischium meloae sp. nov. from Suriname; Acanthischium nigrum Stål, 1872 stat. rev.; Acanthischium semiflavum Stål,1872 stat. rev.; and Acanthischium superbum Haviland, 1931.
