Lomachaeta crocopinna Pitts & Manley, 2004: 10 View Cited Treatment   . Holotype, ♂, USA, Texas, Val Verde Co. (UMSP). Pitts & Manley (2004): Host.

Diagnosis. MALE. The following combination of characters is diagnostic for L. crocopinna  : the body is entirely black, except the metasoma is almost entirely orange; the mandible lacks a ventral tooth basally; the forewing has its veins encompassing the basal 0.65 × of the wing; the head, mesoscutum, and T2 disc have separated punctures; the T1 shape is sub-sessile; the T2 fringe is composed of slightly thickened setae; and the paramere is virtually straight, laterally subcompressed, and having long setae ventrally throughout its length. Body length 3–5 mm.

FEMALE. Unknown.

Distribution. Known from the Arizona Mountains forests, Colorado Plateau, Great Basin, and Chihuahuan Desert in Arizona, Nevada, New Mexico, and Texas ( USA) and Sonora ( Mexico).

Remarks. This is the apparent sister species to L. ptilohyalus  ; the two species share similar coloration and genitalic morphology. The distribution of L. crocopinna  spans multiple ecoregions in the western USA and parallels that of Dilophotopsis concolor (Cresson)  . Wilson and Pitts (2008) described the distribution of D. concolor  and its sister species, D. paron (Cameron)  . Dilophotopsis paron  occurs in the Mojave and Sonoran deserts, as does L. ptilohyalus  . The parallel distributions of these sister-species pairs should be studied more closely, as they could shed light on historic events that impacted the biogeography of numerous velvet ants.
