Diagnosis. MALE. The following combination of characters is diagnostic for L. hicksi : the body is black, though T2–3 are often largely red-brown; the mandible has a ventral tooth basally; the mesoscutum is variably punctate, but never contiguously punctate throughout; the forewing has its veins encompassing the basal 0.8 × of the wing; the T1 shape is disciform; the head and T2 disc have separated punctures; the T2 fringe is composed of thick bristles; and the paramere is virtually straight and lacks elongate setae. Body length 3–6 mm.
FEMALE. This is a hugely variable species in color, setation, and punctation. The following characters are consistent to all L. hicksi : the baso-ventral mandibular margin has a hyaline lamella; the pronotal spiracle is swollen, almost tuberculate; the lateral mesonotal tooth is usually distinct; the propodeal spiracle is sharply swollen and tuberculate; the lateral propodeal face is impunctate; the mesosoma is compact, with the thoracic dorsal length 0.85 × its width; the mesosomal dorsum is areolate without subparallel thickened setae, many intervals are either obliterated or raised to tuberculate corners; the T1 shape is sub-disciform, often with the dorsal and anterior faces separated by a weak carina; T2 has sparse punctures, mostly erect brachyplumose setae, and mostly smooth intervals; and the S6 lateral carina is low angular. Body length 2.5–5 mm.

Distribution. This is the most widespread Nearctic mutillid species, ranging from the Atlantic to Pacific Oceans, North to Massachussetts and South to Florida ( USA) and Puebla ( Mexico).
Remarks. As one of the World’s most widely distributed mutillid species, L. hicksi has the longest synonym list in this genus, belying its tremendous morphological variation. Although fewer females than males have been available to study, they also reveal high variation in color and punctation ( Figs 24–26 View FIGURES 21–26 ). The mesosoma and metasoma each vary from nearly entirely pale orange to nearly black. The mesonotal areolations vary from broadly to tightly areolate, though when the mesonotal areolations are tightly spaced, there are fewer than 12 areolations between the pronotal spiracles and the propodeal areolations are much broader.
The males mentioned above in the Material Examined section are the first known to have orange femora, a trait that was apparently unique to males of L. cirrhomeris . Males of L. cirrhomeris , however, always have cuticle of the metasoma entirely black and contrasting with their orange femora ( Fig. 42 View FIGURES 41–46 ), while these L. hicksi from California have the metasoma predominantly orange and concolorous with the femora ( Fig. 44, 45 View FIGURES 41–46 ). Pitts & Manley (2004) suggested that L. cirrhomeris may eventually prove to be a synonymous color variant of L. hicksi . These males lend additional credence to that hypothesis.
