Observational analysis identifies two new species of Pyrrhocoroidea in Vietnam, suggesting their expanded range.
This study reports one genus and two species of the superfamily Pyrrhocoroidea Amyot & Serville, 1843 (Hemiptera, Heteroptera, Pentatomomorpha) from Vietnam for the first time: Delacampius Distant, 1903 (Largidae, Physopeltinae, Physopeltini), D. villosus (Breddin, 1901), and Euscopus robustus Stehlík, 2005 (Pyrrhocoridae). These species were attracted to light traps placed on the roadside near an evergreen broad-leaved forest in a mountainous area with a subtropical climate. Additionally, the discovery of E. robustus in Vietnam represents the southernmost locality for this species.
