Online citizen sciences reveal natural enemies and new occurrence data of Fujie, Shimizu & Maeto, 2021 (Hymenoptera, Braconidae, Euphorinae).

Background: Citizen science is a research approach that involves collaboration between professional scientists and non-professional volunteers. The utilisation of recent online citizen-science platforms (e.g.

The genus Marshall (Hymenoptera, Braconidae, Euphorinae) from Japan, with description of a new species.

Six Japanese species belonging to the genus Marshall, 1898 (Hymenoptera, Braconidae) were recorded and photographed. Three species, Belokobylskij, Schmiedeknecht and Tobias (= Luo & Chen ), are new to Japan, and a new species, is described. An identification key to the Japanese species of is also provided.

Genomic population structure of sympatric sexual and asexual populations in a parasitic wasp, Meteorus pulchricornis (Hymenoptera: Braconidae), inferred from six hundred single-nucleotide polymorphism loci.

In spite of the two-fold reproductive advantage, asexual reproduction is not common in nature, probably due to the associated genetic deterioration or reduced genetic variation. To understand how genetic diversity is maintained in existing asexual populations, we investigated the genetic diversity and population structure of sympatric sexual and asexual populations of a parasitic wasp, Meteorus pulchricornis, using 614 genome-wide single nucleotide polymorphisms. The genetic structures of the apomictic asexual populations were distinct, showing considerable genetic differentiation among them.

A new species and a key to world species of the flavipes species-group of the genus Cotesia Cameron, 1891 (Hymenoptera: Braconidae: Microgastrinae) from Japan.

A new species of microgastrine parasitoid wasp (Hymenoptera: Braconidae), Cotesia testacea Fujie, Shimizu Fernandez-Triana sp. nov., is described from Japan and Korea.
