Taxonomic uncertainty and a continental conundrum:Polypodium macaronesicumreassessed
2014
Data from the chloroplast trnL-F region are used to test the delimitation of putative diploid species in the Polypodium cambricum aggregate. In particular, we investigate the distinctiveness of the Macaronesian Polypodium macaronesicum, P. azoricum and the continental P. cambricum, investigate molecular diversity patterns within Macaronesia and establish the identity of putative P. macaronesicum material collected from an area in southern Spain, where it co-occurs with other Macaronesian elements. The analysis supports the distinction of Macaronesian and continental plants, with accessions from Macaronesia resolved as monophyletic. Greater haplotype diversity was found in Macaronesia than o…

Taxonomy and evolution of the Triassic conodont Pseudofurnishius
2013
Pseudofurnishius is a late Anisian (Pelsonian)—early Carnian (Cordevolian) conodont genus of gondolellid stock, characteristic for the Sephardic Province and restricted to the “Southern Tethys” region of the northern margin of Gondwana. Its most commonly found species, Pseudofurnishius murcianus, appears at the base of the Ladinian (Fassanian). The Ladinian material of Spain reveals its ontogeny characterised by initial lateral protrusions from the carina that may develop first mono-platform and later bi-platform units, finally evolving into elaborated multi-denticulated forms. The late Anisian—early Carnian phylogenesis of Pseudofurnishius priscus → P. shagami → P. murcianus is proposed. A…
Discussion about the stratigraphic range of "Pseudofurnishius murcianus" van den Boogaard (Conodonta) in the Iberian Peninsula, from the Calasparra s…
2011
The biostratigraphy of Calasparra Section is well-estabished with an ammonoid biozonation and ranges from Lower to Upper Ladinian. The continuous presence of Pseudofurnishius murcianus van den Boogaard, a characteristic conodont species of the Sephardic realm, along the section makes it one of the most important sections in the Iberian Peninsula for the study of the species. The first apparition of P. murcianus in the section corresponds with the first of Eoprotrachyceras curionii taxon, which is the principal marker for the base of the Ladinian stage in the GSSP of the Anisian-Ladinian boundary, and the age of the youngest conodonts, based on ammonoids (Epigonus Zone) is Lower Ladinian (up…
El género <i>Lysaphidus</i> (Hymenoptera: Braconidae) en la Península Ibérica
1995
The genus Lysaphidus Smith, 1944 (Hymenoptera, Braconidae, Aphidiinae) is recorded for the first time from the Iberian Peninsula represented by two species: L. arvensis Stary, 1960, first record for the Iberian Peninsula, and L. santolinae n. sp., both of them parasitoids of Coloradoa Wilson,1910 genus (Homoptera, Aphididae). The mummies were collected on Santolina chamaecyparissus L. and Santolina rosmarinifolia L. (Asteraceae).

Taxonomic Revision of the Genus Trictenotoma Gray, 1832 (Coleoptera: Trictenotomidae). Part 3 – Species from the Philippine Archipelago, with Descrip…
2021
The species of Trictenotoma Grey, 1832 from the Philippine Archipelago are critically assessed, description of T. boudanti Drumont et Telnov sp. nov. from Balabac and Palawan, and a redescription of T. cindarellaKriesche, 1921 from Mindanao are provided. A key to the Philippine Trictenotomidae Blanchard, 1845 is presented for the first time.
Rare and threatened pondweed communities in anthropogenic water bodies of Opole Silesia (SW Poland)
2011
The paper presents results of geobotanic studies conducted in anthropogenic water bodies like excavation ponds, fish culture ponds, other ponds, dam reservoirs, ditches, channels and recreational pools incl. watering places in Opole Silesia and surroundings in the years 2002-2005. The research focused on occurrence of threatened and rare pondweed communities. As the result of the investigations of several dozen of water bodies, 28 localities of rare pondweed communities were documented by 75 phytosociological relevés. Associations of <em>Potametum trichoidis</em> J. et R Tx. in R. Tx. 1965, <em>Potametum praelongi</em> Sauer 1937, <em>P. alpini</em> Br.-B…
Range-wide phylogeography and taxonomy of the marine rock pools dweller Tigriopus fulvus (Fischer, 1860) (Copepoda, Harpacticoida)
2021
In the light of the wide distribution and ecological importance of the genus Tigriopus in coastal rock pool habitats, and of its frequent use in aquaculture and as a model organism, we investigated the identity of the Atlantic–Mediterranean Tigriopus populations and elucidated their taxonomy and patterns of morphological and genetic diversity. In order to reach these goals, an “integrative taxonomy” multisource approach was implemented. First, we investigated the constancy and taxonomical value of the morphological characters currently used to distinguish among the Tigriopus species occurring in the Mediterranean and in Eastern Atlantic area north of the Tropic of Cancer, and checked the ac…
Andricus cydoniae Giraud, 1859 Junior Synonym of Cynips coni-fica Hartig, 1843, as Experimentally Demonstrated (Hymenoptera: Cynipidae: Cynipini)
2022
We demonstrated the life cycle closure of Cynips conifica Hartig, 1843 (presently Andricus conificus), previously supposed on the basis of molecular data, and the identity of the sexual generation, through laboratory experiments. As a consequence, Andricus cydoniae Giraud, 1859 became a junior synonym of A. conificus (Hartig, 1843). We provide illustrations and a diagnosis for adults and galls, observations on biology, and information on distribution. Moreover, as sexual galls of A. conificus cannot be distinguished from those of Andricus multiplicatus, a detailed comparison between sexual galls and adults of these two species is reported.
