( Fig. 51View FIGURES 47–52)

Lomachaeta ptilohyalus Pitts & Manley, 2004: 12 View Cited Treatment   . Holotype, ♂, Mexico, Oaxaca, 10 m North of Huajuapan de Leon (CNCI). Pitts & Manley (2004): Host.

Diagnosis. MALE. The following combination of characters is diagnostic for L. ptilohyalus  : the body is entirely black, except T2–3 are largely orange; the mandible lacks a ventral tooth basally; the head and T2 disc have separated punctures; the mesoscutum has sparse punctures; the forewing has its veins encompassing the basal 0.7 × of the wing; the T1 shape is sub-sessile; the T2 fringe is composed of simple setae; and the paramere is virtually straight, laterally subcompressed, and having long setae ventrally throughout its length. Body length 4–6 mm.

FEMALE. Unknown.

Material examined. USA: Arizona: Maricopa County, Gila River , 10 km S. Arlington, malaise on sand beach, 200 m, 33°13.3’N 112°45.53’W, 25.V–03.VI.2010, M. E. Irwin (1♂, CSCA, Fig. 51View FIGURES 47–52)GoogleMaps  .

Distribution. This species has an apparently disjunct distribution in the Mojave and Sonoran Deserts (Arizona and California, ( USA) and Balsas Dry Forests (Oaxaca, Mexico).

Remarks. The holotype from Oaxaca, Mexico is separated from the other known specimens of L. ptilohyalus  in hot deserts of the USA by over 2300 km. Further collections in Mexico may reveal other populations, or molecular data comparisons between Oaxacan and hot desert specimens may reveal that they are not conspecific. Either way, this is a compelling link between disjunct arid habitats of southern Pacific Mexico and the North American hot deserts.
