A survey was conducted in Walkerville, south of Johannesburg (Gauteng, South Africa) between 2012 and 2016 to ascertain the diversity of entomopathogenic nematodes in the area. Entomopathogenic nematodes are soil-dwelling microscopic worms with the ability to infect and kill insects, and thus serve as eco-friendly control agents for problem insects in agriculture. Steinernematids were recovered in 1 out of 80 soil samples from uncultivated grassland; soil was characterised as loamy. The entomopathogenic nematodes were identified using molecular and morphological techniques. The isolate was identified as Steinernema australe. This report is the first of Steinernema australe in South Africa. S. australe was first isolated worldwide from a soil sample obtained from the beach on Isla Magdalena – an island in the Pacific Ocean, 2 km from mainland Chile.

The marine fish family Emmelichthyidae is redefined to include only the genera Emmelichthys (four species), Erythrocles (four species) and Plagiogeneion (two species). Two new species of Emmelichthys from the Pacific Ocean are described. Emmelichthys nitidus Richardson is divided into two subspecies: E. nitidus nitidus occurring from South Africa to New Zealand and E. nitidus cyanescens (Guichenot) from the Juan Fernandez Islands and coast of Chile. Descriptions and keys to the genera and species are provided.

ABSTRACT In 1988, Aedes albopictus was first described in Mexico. Since then, it has been recorded in most of the coastal states that have a shoreline on the Gulf of Mexico, 3 states in Central Mexico and 2 states on the coast of the Pacific Ocean. This is the first report documenting the presence of this invasive species in Guerrero, a state with coastlines on the Pacific Ocean. This evidence suggests that the distribution of Ae. albopictus is expanding throughout Mexico. It remains unknown the extent to which Ae. albopictus contributes to vector-borne disease transmission in this country; however, the risk should not be neglected
