Review and phylogeny of Cyrtomenus Amyot & Serville (Hemiptera: Cydnidae: Cydninae) based on morphological characters.

Cyrtomenus includes seven species arranged in two subgenera and belongs to the most diverse subfamily of burrower bugs, Cydninae. The species present polyphagous habits, and at least two species are considered crop pests. We conduct a phylogenetic analysis based on morphological characters and two weighting schemes to test its monophyly and the validation of the included subgenera, providing for the first time a phylogenetic hypothesis for the genus.

First record of the family Azotidae from Ecuador, with a description of a new species of Ablerus Howard (Hymenoptera: Chalcidoidea: Azotidae) from the Galapagos Islands.

Azotidae (Hymenoptera: Chalcidoidea) is a small family (1 genus, 92 species) comprised primarily of hyperparasitoids of species of Hymenoptera that target whiteflies and scale insects. In the present study, we provide the first record of the genus Ablerus Howard, 1898 (=Azotus Howard 1898) from the Galapagos Islands, based on material collected in a survey of Hymenoptera across the archipelago's main islands. One new species, Ablerus byroni sp.

Synonymy of two important crop pests of burrower bugs, Cyrtomenus mirabilis and C. bergi (Hemiptera: Cydnidae), based in a multi-source approach.

Burrower bugs are unique among true bugs, recognized by the morphological adaptations for digging, and include several species of economic importance for causing damages in roots and ground pods. Damage records has been growing in the last two decades in the Neotropics, but taxonomic problems still hampers studies in these group of insects. Cyrtomenus bergi Froeschner and C.

Cydninae (Hemiptera, Heteroptera, Cydnidae) in Brazil: updated checklist, new records, and description of sp. nov.

Cydninae is the largest subfamily among burrower bugs all around the world and for Brazil the genera Cyrtomenus, Dallasiellus, Ectinopus, Melanaethus, Onalips, Pangaeus, Prolobodes and Tominotus were reported with a total of 39 species, so far. Basing on the material of nine entomological collections, we updated the list to 47 species including new records and a new species, Tominotus ondulatus sp. nov.
