Typification of seven names in the genus Antirrhinum (tribe Antirrhineae, Plantaginaceae)
2021
The typification of seven names in the genus Antirrhinum (tribe Antirrhineae, Plantaginaceae): A. charidemi, A. latifolium, A. molle var. mollissimum, A. molle var. marianum, A. sempervirens, A. siculum, and A. valentinum is discussed. The designation of the nomenclatural types is based on the consultation of original material and the literature cited in the respective protologues. The names are lectotypified using specimens from BC, C, MA, and an illustration of Boccone published in 1697. An epitype is also designated for A. latifolium due to ambiguity in the interpretation of the lectotype. The name A. siculum is neotypified from a specimen preserved at VAL, and a second-step lectotypific…
Presence of Naraoia Walcott, 1912 (Nektaspida, Arthropoda) in the middle Cambrian of Europe (Murero, NE Spain).
2018
The genus Naraoia Walcott, 1912, a Burgess Shale-type fossil known from the lower and middle Cambrian of British Columbia (Canada), Idaho and Utah (USA), as well as from Yunnan and Guizhou provinces (China), is now reported from the middle Cambrian of Murero (Zaragoza, Spain), which is the first record in the Acadobaltic province. The only fragmented specimen found is determined as Naraoia sp., its age being Pardailhania multispinosa Zone (Drumian Stage). This new datum reinforces the hypothesis of the existence of a cosmopolitan faunal substrate in early Cambrian times, which is to some extent refl ected in the mid Cambrian by faunal groups of low evolutionary potential as the family Narao…
The monophyly and evolution of Cynara L. (Asteraceae) sensu lato: evidence from the Internal Transcribed Spacer region of nrDNA
2005
The monophyly and evolution of Cynara was investigated using ITS sequence data. Parsimony analysis supports the monophyly of Cynara sensu lato, i.e. including the distinctive taxa C. humilis and C. tournefortii. This contradicts the recent decision to create a new monotypic genus Arcyna for C. tournefortii. A hypothesised close relationship between C. tournefortii and Silybum Adans. is also refuted. Four of the five species of Cynara, for which multiple accessions were sequenced, were shown to be monophyletic but C. baetica was found to be non-monophyletic. Free energy estimates for ITS1 secondary structure and conservation of the 5.8S region suggest that this is not due to the occurrence o…
Robinia aurata n. g., n. sp. (Digenea: Hemiuridae) from the mugilid Liza aurata with a molecular confirmation of its position within the Hemiuroidea.
2006
Robinia aurata n. g., n. sp. is described from Liza aurata (Mugilidae), the golden grey mullet, from the Ebro Delta, Spanish Mediterranean. The new genus differs from all other hemiurid genera in the combined possession of muscular flanges and a vestigial ecsoma. Within the Bunocotylinae, which currently accommodates 2 genera, Bunocotyle and Saturnius, the new genus exhibits a unique combination of blind caeca, Juel's organ, post-ovarian bulk of the uterus in the hind-body, and tegumental papillae surrounding the oral and ventral sucker apertures. Furthermore, Robinia n. g. differs from both Bunocotyle and Saturnius in the nature of the muscular extensions around the oral sucker, with the s…
<strong>First record of the plant bug genus <em>Euchilofulvius</em> from Myanmar (Hemiptera: Heteroptera: Miridae: Cylapinae), with…
2015
The cylapine plant bug genus Euchilofulvius was proposed by Poppius (1909) to accommodate a single Indonesian species, E. tibialis Poppius from Mentawai Islands. Several subsequent works have fragmentally added six valid species (Gorczyca, 2006, 2008; Poppius, 1913; Schuh, 1995, 2002–2014 online catalog; Yasunaga & Miyamoto, 2006; Yasunaga et al., 2012), and currently, the following seven members are known mainly from the Oriental Region: E. antennatus Gorczyca, 1999 (Sulawesi); E. carinatus (Poppius, 1913) (India, Sri Lanka); E. josifovi Gorczyca, 2008 (Malaya); E. lepidopterus Yasunaga & Miyamoto, 2012 (Okinawa, Japan); E. pallescens Gorczyca, 2002 (Solomon Islands); E. tibialis Poppius, …

2013
The genera Peritropisca Carvalho & Lorenzato, 1978 and Rewafulvius Carvalho, 1972 are redescribed. A description of a new species of the genus Peritropisca from Indonesia— P. laticostata sp. nov. and a redescription of P. bituberculata Carvalho & Lorenzato, 1978 are provided. The genus Euchilofulviella Gorczyca, 1999 is proposed as a junior synonym of Rewafulvius Carvalho, 1972 syn. nov. A color habitus picture of the adult and male genitalia drawings of each treated species are provided. A key to the genus Peritropisca is given.
REINSTATEMENT OF THE DINOFLAGELLATE GENUS Tripos TO REPLACE Neoceratium, MARINE SPECIES OF Ceratium (DINOPHYCEAE, ALVEOLATA)
2013
Morphological and molecular data support the split at the genus level of the marine and freshwater species of the dinoflagellate Ceratium (Gonyaulacales, Dinophyceae). A new genus name Neoceratium F. Gomez, D. Moreira & P. Lopez-Garcia was proposed for the marine species. However, it is considered illegitimate (type species is type of Biceratium Vanhoffen), and the nomenclatural priority is here given for the genus Tripos Bory (type species Tripos muelleri ) which replaces Neoceratium . New combinations are proposed for the existing names of species and infraspecific taxa.

Additions to the Nepalese oribatid mite fauna, with description of two new species (Acari, Oribatida)
2013
An annotated checklist of identified oribatid mite taxa from Nepal is provided. It includes 45 species/subspecies, 38 genera and 31 families; 34 species/subspecies are recorded for the first time in Nepal. Two new species, Eremaeus anichkini n. sp. (Eremaeidae) and Ghilarovizetes longiporosus n. sp. (Ceratozetidae), are described from soil and litter. An identification key to all known species of the genus Ghilarovizetes is given.urn:lsid:zoobank.org:pub:BE27D886-1294-4E55-AD0B-25CDFC663D71
<p><strong>Towards resolving a problem of the identity of the <em>Aethus</em> species (Hemiptera: Heteroptera: Cydnidae) occu…
2014
The genus Aethus in Cambodia is known only from a single species collected in the 1950s that was originally identified as A. indicus. However, what was regarded as A. indicus in the Oriental and Australian regions appeared to consist of three sibling species, recognizable only on the basis of male genital structures, i.e., A. philippinensis, A. pseudindicus, and true A. indicus. To date, the lack of males representing this genus from Cambodia made it impossible to verify which species actually occur in this country. The present study, based on eight males collected at the same locality in Cambodia where the specimens were originally identified as A. indicus more than 50 years ago (i.e., Sie…
A Revision of theniveaGroup of the Shore-Fly GenusDitrichophoraCresson (Diptera: Ephydridae)
2010
ABSTRACT Species of the nivea group (genus Ditrichophora Cresson) are revised. The group now includes four species of which one, D. gulkana (Alaska and Mongolia), is newly described. The group is now known to have a Holarctic distribution with two species, D. gulkana and D. nivea, being the first reported from the Nearctic Region. Another Asian species, D. brunnicosa, previously placed in Diclasiopa, is transferred to this group (genus Ditrichophora) and is also reported from Mongolia. To facilitate identification of these rare species, we have included diagnoses of the tribe, genus, and species group and have also provided an annotated key to Holarctic genera of the tribe Discocerinini and…
