However, the taxonomy and nomenclatural history of the species complex are complicated and rather confusing, because the species within the group often lack an adequate description and an exhaustive differential diagnosis drawing clear morphological and ecological species boundaries. To fill in this gap we examined the type materials of five different Achnanthidium species using light and scanning electron microscopy: Achnanthidium catenatum (J. Bilý et Marvan) lange-Bert., A. dolomiticum Cantonati et lange-Bert., A. eutrophilum (lange-Bert.) lange-Bert., A. saprophilum (H. KoBayasi et MayaMa) round et BuKHt. and A. straubianum (langeBert.) lange-Bert. Frustular morphology of the five taxa was studied in order to provide complementary information on the variability and ultrastructure of the nomenclatural types related to the A. minutissimum species complex. Our observations are mostly consistent with the original descriptions. Comparisons of morphological characters observed with the SEM showed that all species are closely related having many morphological features in common; however, they differ in the shape and variability of areolae. The SEM investigations demonstrated that ultrastructural characters on their own do not distinctly discriminate among the taxa. Morphometric comparisons indicated that the only distinct morphological features that could separate the Achnanthidium species studied are valve outline, striation pattern and valve dimensions.","PeriodicalId":90782,"journal":{"name":"Algological studies (Stuttgart, Germany : 2007)","volume":"136 1","pages":"19-43"},"PeriodicalIF":0.0,"publicationDate":"2011-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1127/1864-1318/2011/0136-0019","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64040966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The species has an elongate, linear-elliptical valve outline with clearly capitate apices.

Achnanthid- ium caravelense Novais et Ector is described as a new species based on light and scanning electron microscopic observations, as well as on its ecological preferences as reconstructed from field observations. The most characteristic morphological features of this species are the different outline of the raphe valve (narrowly elliptic with linear margins) and the ra- pheless valve (narrowly elliptic to narrowly rhombic with moderately convex margins), the non-protracted broadly rounded apices and the length/width ratio. Furthermore, the areolae of the single row along the mantle are elongated and are more or less widely open, which is a characteristic discernible in girdle view under light microscopy. The species that A. caravelense resembles most is A. eutrophilum (LaNgE-BErt.) LaNgE-BErt.; nevertheless it can be distinguished from the latter by the different raphe valve outline, its higher valve length/width ratio and autecology. A. caravelense is common and abundant in soft waters with low to moderate nutrient content in the North of Portugal.","PeriodicalId":90782,"journal":{"name":"Algological studies (Stuttgart, Germany : 2007)","volume":"136 1","pages":"131-150"},"PeriodicalIF":0.0,"publicationDate":"2011-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1127/1864-1318/2011/0136-0131","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"64041170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
