Species delimitation using morphology, morphometrics, and molecules: definition of the Ophion scutellaris Thomson species group, with descriptions of six new species (Hymenoptera, Ichneumonidae)

Abstract The diverse genus Ophion is almost entirely undescribed in the Nearctic region. In this paper we define the Ophion scutellaris species group. This species group is well-supported by analysis of DNA (ITS2, COI, and 28S D2-D3) and morphology. It includes the Palearctic species Ophion scutellaris and the Nearctic species Ophion idoneus. An integrative analysis of DNA, geometric wing morphometrics, classical morphometrics and qualitative morphology indicates that this species group contains a minimum of seven species in North America, although the full diversity of the group has likely not been sampled. Ophion clave Schwarzfeld, sp. n., Ophion aureus Schwarzfeld, sp. n., Ophion brevipunctatus Schwarzfeld, sp. n., Ophion dombroskii Schwarzfeld, sp. n., Ophion keala Schwarzfeld, sp. n. and Ophion importunus Schwarzfeld, sp. n. are described, and a key to the known Nearctic species of the Ophion scutellaris group is provided.
