Tricorythodes molinerii sp. n. is described and illustrated based on nymphs from southeastern Brazil. The new species can be distinguished from other species of Tricorythodes Ulmer by the following characters: 1) genal projection present; 2) maxillary palp bi-segmented, with short apical seta; 3) pronotum with well developed anterolateral projection; 4) dorsum of fore femora with a transverse r...

Portugal has a rich fossil record both on the continent and in Azores islands (Santa Maria). For decades, researchers have found thousands of fossils identified hundreds species from major taxonomic groups. The present work focuses analyzing scientific literature Chondrichthyes collected fossiliferous deposits Neogene. Fossils sharks rays, teeth, dermal denticles, caudal spines were discovered ...

A new Dipterus−like lungfish, Harajicadipterus youngi, is described from the Givetian (Middle Devonian) Harajica Sand− stone Member of central Australia. The material is comprised of five specimens representing the skull roof, orbital bones, tooth plates, operculo−gular bones, a partial pectoral girdle, centra and scales. Harajicadipterus can be distinguished from other dipnoans by its long pos...

A new genus of Baetidae, Megalabiops gen. nov. , and a species, M. madagasikara sp. are described from Madagascar based on nymphs. The is characterized by having strongly enlarged mentum; pedicelli with many long, stout, pointed setae; brush dense, short setae between prostheca mola both mandibles; an apically maxillary palp stout seta at the tip; labium simple ventrally glossae. patellotibial ...

A new genus and species of digamasellid mites is described based on adult females males. Bulbolaelaps bossei n. gen., sp. was collected from the fruiting bodies gilled fungi a tree trunk in Zanjan province, Iran. The can be distinguished other genera Digamasellidae by having bulbous swollen protuberance venter palptrochanter; corniculi weakly formed epistome sclerotised; hypostomal setae h1 h2 ...

Macrobrachium aemulum madhusoodani Pillai & Unnikrishnan (2013) was recently described based on material from the Neyyar River, Kerala, India as a new subspecies of M. aemulum (Nobili, 1906). As however, both species and subspecies names are considered part of the species-group for nomenclatorial purposes (ICZN, Art. 45.1), the name is a junior homonym of Macrobrachium madhusoodani Unnikrishnan...

A sample of late Visean limestone from the Wlodawa IG-4 borehole, east Lublin, Poland, yielded a piece tooth and few hundred well-preserved scales comparable to those “Ctenacanthus” costellatus Traquair, 1884 Glencartholm, Scotland, UK. Most are typical compound body ctenacanthid type. Their crowns composed several separate odontodes whose distal ends turned backwards bases characterised by con...

Sampling of rice fields in Kanagawa Prefecture, Japan, yielded an undescribed species the non-marine ostracod genus Sarscypridopsis McKenzie, 1977. Small marginal denticles on left valve give this its name: denticulata n. sp. Most are restricted to Africa, and based morphological characters, closest congener new is native Botswana. We therefore conclude that probably not it joins six other or p...

Mandibles are prominent masticatory structures in the mouth parts of grasshoppers provided an opportunity to analyze structural variations among different species grasshoppers. In this study mandibles twenty short horned examined for two reasons - whether grasshopper bear any taxonomic significance and test if one could use mandible establish inter relationships The morpho plan having incisor, ...

Odontoma is a hamartomatous lesion of odontogenic origin involving both epithelial and mesenchymal tissues.
