Family Mantispidae (Mantidflies)

Synonyms and other taxonomic changes
Recent taxonomic changes have restricted genus Mantispa to Old World species, see comments here.
Numbers
Nearctica.com lists six genera and 15 species, as does Arnett, p. 348 (1). With current genera erected from Mantispa, the taxonomy of the nearctic members should look like:
-Subfamily Symphrasinae
Plega Navas (4 spp., Southwest)
-Subfamily Calomantispinae
Nolima Navas (3 spp., Arizona, Texas)
-Subfamily Mantispinae
Climaciella Enderlein (1 sp., widespread)
Dicromantispa Hoffman (2 spp., widespread, mostly East)
Leptomantispa Hoffman (1 sp.?, widespread)
Xeromantispa Hoffman (1 sp.?, West?)
Zeugomantispa Hoffman (1 sp., East)
Size
20-35 mm
Identification
Bizarre creatures--resemble lacewings with raptorial forelegs, like a mantid. One species is a wasp mimic. Arnett, gives a key to subfamilies, p. 348 and to genera of Mantispinae, p. 349 (1). Family characteristics (1) (2):
prothorax elongated, neck-like
front legs modified for catching prey--with claw and spines
front legs originate from anterior part of thorax (at front of elongated prothorax), so that only four legs are usually used for walking--front legs are held up, used for catching prey
head triangular with large eyes, mantid-like
Range
Mostly southern North America
Food
Predatory
Life Cycle
Stalked eggs typically laid in large numbers. Larvae undergo hypermetamorphosis. In some genera, larvae are parasitoids of spiders. Others are more generalist predators of other insects, especially terrestrial larvae of scarab beetles, noctuid moths, and certain wasps.
