Nasopharyngeal Botflies Oestrus ovis and Cephenemyia stimulator in Roe Deer (Capreolus capreolus) from Northern Spain.

Two of 19 roe deer (Capreolus capreolus) in northern Spain were infested with Cephenemyia stimulator and one individual with Oestrus ovis. Three larvae of O. ovis were recovered from the nasopharynx of an adult female deer examined in February 2017, during the hunting season in the province of Burgos.

Morphological and molecular characterization of two species of nematodes (Oxyuridomorpha: Thelastomatoidea: Protrelloididae, Thelastomatidae) parasitic in the cockroach Blaberus discoidalis Serville (Blattaria: Blaberidae) from Cuba.

Protrelleta floridana Chitwood, 1932 and Cranifera cranifera (Chitwood, 1932) (Oxyuridomorpha: Thelastomatoidea: Protrelloididae, Thelastomatidae) are recorded for the first time in Cuba. These nematodes were found to parasitize the cockroach Blaberus discoidalis Serville (Blattaria: Blaberidae), constituting a new host record for them. Both species are redescribed with the aid of scanning electron microscopy and the arrangement of the copulatory papillae of the males of P.

PHYLOGENETIC ANALYSIS OF THE LUNGWORMS (NEMATODA: METASTRONGYLOIDEA) INFERRED USING NUCLEAR RIBOSOMAL AND MITOCHONDRIAL DNA SEQUENCES.

Phylogenetic relationships among the mammal-parasitic lungworms (Metastrongyloidea) were inferred using small- and large-subunit ribosomal DNA sequences together with 12S ribosomal mtDNA sequences. Maximum parsimony and Bayesian inference methods were used from optimal alignments and those filtered for alignment ambiguity. Analysis of 30 ingroup sequences using ribosomal DNA sequences yielded a single most parsimonious tree.

Three new genera and new species of hystrignathid nematodes (Nematoda: Thelastomatoidea) from passalid beetles (Insecta: Passalidae) from Yunnan Province, China with phylogenetic analysis of Hystrignathidae.

Three new genera and three new species of hystrignathid nematodes were collected from the hindgut of passalid beetles in the Yunnan Province, China. Huntia morffei gen. n.
