Description of eight new Anomala species from Costa Rica (Coleoptera: Scarabaeidae: Rutelinae)

Eight new species of Anomala from Costa Rica are described: A. arthuri new species, A. cupreovariolosa new species, A. ferrea new species, A. nigroflava new species, A. semilla new species, A. solisi new species, A. volsellata new species, A. zumbadoi new species and a distribution map of each is given. The male genitalia (aedeagus and endophallus) of the species covered are illustrated.

Description of two cryptic species of Anomala Samouelle (Coleoptera: Scarabaeidae: Rutelinae) from Costa Rica

Two new species of Anomala Samouelle from Costa Rica are described: Anomala moroni new species and A. parvaeucoma new species. Habitus, protibia, distribution map, and male genitalia (aedeagus and endophallus) of each species are illustrated. A key for the dorsally setose species from the Neotropical region is provided.

An integrated approach to delimiting species borders in the genus Chrysotoxum Meigen, 1803 (Diptera: Syrphidae), with description of two new species

Integrative taxonomy tests the validity of taxa using methods additional to traditional morphology. The existence of two different morphotypes in specimens identified as Chrysotoxum vernale Loew (Diptera: Syrphidae) prompted their taxonomic study using an integrative approach that included morphology, wing and male-surstylus geometric morphometrics, genetic and ecological analyses. As a result, a new species is recognised, Chrysotoxum montanum Nedeljković & Vujić sp. nov., and C. vernale is re-defined. A lectotype and paralectotypes are designated for C. vernale to stabilize this concept. An additional species, Chrysotoxum orthostylum Vujić sp. nov., with distinctive male genitalia is also described. The three species share an antenna with the basoflagellomere shorter than the scape plus pedicel and terga with yellow fasciae not reaching the lateral margins. This study confirms the value of integrative approach for resolving species boundaries.
