Diploplectron

Diploplectron species can be distinguished from other Astatinae by the combination of two submarginal cells in the forewing and a complete, well-developed episternal sulcus on the mesopleuron. The pronotum is short and does not reach the tegulae. These characters separate Diploplectron from the closely related genus Astatinae, which typically has three submarginal cells.

Species of Diploplectron occur in North America, with records from the United States and Mexico. The genus shows greatest diversity in arid and semi-arid regions of the southwestern United States.

Adults have been observed from spring through late summer, with peak activity during the warmer months when prey availability is highest.

As members of the Astatinae, Diploplectron species function as predators that help regulate populations of their prey, which are likely small insects or spiders. The wasps serve as both predators and prey within food webs, contributing to ecosystem balance in their native habitats.

• Astatinae (subfamily)Other genera within Astatinae share the general thread-waisted wasp morphology; Diploplectron is distinguished by wing venation and mesopleural characters.
• Crabronidae (family)Other crabronid wasps may resemble Diploplectron in general form; precise identification requires examination of wing venation and thoracic sutures.
