The genus Speonemadus Jeannel, 1922 currently includes 12 species distributed in the Western Mediterranean (Iberian Peninsula, North Africa, Sicily and continental Italy). Two new species are described from Morocco, S. brusteli sp. n. from the Rif and S. comasi sp. n. from the High Atlas, the first in the S. vandalitiae-group of species and the second with an isolated position within the genus. Two species are also resurrected from synonymy, S. pulchellus (Reitter, 1885) stat. rest. (former synonym of S. orchesioides (Fairmaire, 1879)) and S. gracilis (Kraatz, 1870) stat. rest. (former synonym of S. vandalitiae (Heyden, 1870)), raising the total number of species of the genus to 16. Lectotypes are designated for Anemadus pulchellus Reitter, 1885, and Anemadus tenuipes Peyerimhoff, 1917. A molecular phylogeny of the genus Speonemadus is presented, based on a combination of mitochondrial and nuclear genes and including seven of the currently recognised species, one of the newly described (S. brusteli sp. n.) and the two reinstated taxa. The genus is estimated to have diversified from the late Miocene (Tortonian), with successive cladogenetic events related to the isolation of landmasses between Iberia and North Africa, including the opening of the Strait of Gibraltar at the end of the Messinian. The distribution of some of the species of Speonemadus remains still uncertain, due to their frequent misidentification and the problems with their taxonomic status.

A key trait of Eukarya is the independent evolution of complex multicellular (CM) in animals, plants, fungi, brown algae and red algae. This phenotype is characterized by the initial exaptation of cell-cell adhesion genes followed by the emergence of mechanisms for cell-cell communication, together with the expansion of transcription factor gene families responsible for cell and tissue identity. The number of cell types (NCT) is commonly used as a quantitative proxy for biological complexity in comparative genomics studies.

The deer fly (Diptera, Tabanidae), Chrysops dispar Fabricius is a common and widespread pest and vector species transmitting pathogens to animals including economically significant livestock. However, there is only limited information on genetic diversity, which crucial for understanding disease epidemiology. In this study, we examined genetic diversity of C.

Ticks are obligate hematophagous arachnids that feed on both humans and animals. Despite the extensive research on detection of bacteria in ixodid ticks in Malaysia, there remains limited knowledge about the detection of protozoa in these ectoparasites, especially in those that feed on farm ruminants. In this study, 1,241 ticks belonging to four species (Rhipicephalus microplus, R.
