Eya, B.K. 2015. Revision of the genus Crioprosopus Audinet-Serville, and description of three new genera of Trachyderini (Coleoptera: Cerambycidae: Cerambycinae). Zootaxa 3914(4): 351–405.
The genera Callona Waterhouse, 1840 and Crioprosopus Audinet-Serville, 1834 (Coleoptera: Cerambycidae: Cerambycinae: Trachyderini) are revised. The genus Callona is synonymized with Crioprosopus, and new genera, Callistochroma gen. nov., Megapurpuricenus gen. nov. and Pilostenaspis gen. nov. are described. Five species, three previously included in Callona [C.

Distributional information is presented for Megaderus bifasciatus
Dupont, 1836, a rare species of longhorned beetle in the cerambycid tribe Trachyderini. Valid occurrence records from Mexico and Central America are listed, and enigmatic historical records for the southwestern United States are examined to attempt to determine their veracity. An inventory of specimens found in museum collections is documented. The records for Texas and Arizona are examined, and the likelihood that the species is, or ever was, present in the United States is discussed.
Revision of the genus Deltaspis Audinet-Serville, 1834 with systematic analysis and new taxa of Trachyderini....By Eya, B. K.
Zootaxa 4713(1):1-62, 2019
Eya, B. K. 2019. Revision of the genus Deltaspis Audinet-Serville, 1834 with systematic analysis and new taxa of Trachyderini with emarginate-truncate mandibles (Insecta: Coleoptera: Cerambycidae). Zootaxa 4713(1):1-62.
Affects both species of Deltaspis known from North American North of Mexico. Deltaspis tumacacorii is transferred into Muscidora Thomson, 1864. Deltaspis ivae is transferred into Neoxoplus, new genus. An amendment to Linsley's (1962) Crossidus key is also included.
A number of other new combinations and descriptions of new species from Mexico are provided as well as a description for an additional new genus, Deltaspiopsis.
A Distributional and Taxonomic Study of the Genus Crossidius (Coleoptera, Cerambycidae)By E. G. Linsley & J. A. Chemsak
Entomological Society of America Miscellaneous Publications 3(2):26-54., 1961
A very informative and useful treatment of the genus, covering the 15 species (+ 35 more subspecies!) of Crossidius
as circumscribed at the time of publication.
Includes keys to species, description of species & subspecies, and detailed range info...as well as introductory info on biology, host plants, etc.
According Larry Bezark's 2015 Checklist
(see pp. 186-7), two more species have been described since Linsley & Chemsak's 1961 work here:
