Ferro, M.L. 2015. Review of the genus Thoracophorus (Coleoptera: Staphylinidae: Osoriinae) in North America north of Mexico, with a key to species. The Coleopterists Bulletin 69(1): 1–10.

Abstract
Three species of Thoracophorus Motschulsky (Staphylinidae: Osoriinae) are reported from North America north of Mexico: T. brevicristatus (Horn), T. costalis (Erichson), and T. guadalupensis Cameron. A survey of nearly 5,000 specimens from 38 institutions showed that T. costalis was the most common and widespread of the three species, representing 99% of all specimens and ranging throughout eastern North America west to central Texas and north to Edmonton, Alberta, Canada. Thoracophorus brevicristatus is found across the extreme southern USA from Arizona to Florida. Thoracophorus guadalupensis is found only in Florida. A key to species and range maps are provided.

Agrilus quercicola (Fisher) (Coleoptera: Buprestidae), the Gambel Oak Borer, as a Pest of Quercus spp.
By Andrea Sever, Whitney Cranshaw, Robert Brudenell
Southwestern Entomologist, 2012
Abstract
During 2003 an unusual outbreak of the Gambel oak borer, Agrilus quercicola (Fisher), caused extensive damage to several species of oak in Denver, Araphaoe, and Douglas counties in Colorado. This followed several seasons of environmental stress that predisposed Gambel oak to the insect, but adults apparently dispersed more than 30 km during this outbreak to kill oaks a considerable distance from native Gambel oak stands. In choice tests, adults fed on foliage of Gambel oak, but not other herbaceous shrubs common in stands of Gambel oak. Yellow and neon yellow-green, but not white, sticky traps caught considerable numbers of adults. Adult flight activity began in late May, peaked in early summer, and ended in late August. A chalcid parasitoid, Phasgonophora sulcata Westwood, was noted to be an important natural enemy. No injury by this insect has been observed outside of native Gambel oak in years subsequent to the 2003 outbreak.

Two new species of Agrilus Curtis 1825 from Arizona and Texas, with a new synonymy in Agrilus (Coleoptera: Buprestidae).

Barr, W.F. 2008. Two new species of Agrilus Curtis 1825 from Arizona and Texas, with a new synonymy in Agrilus (Coleoptera: Buprestidae). Zootaxa 1681: 31-36.

Abstract

Two new species of the genus Agrilus Curtis, are described:
A. montosae n. sp. from Arizona and
A. bespencus n. sp. from Texas.
A new synonymy is proposed: A. pubescens Fisher 1928 (= A. parapubescens Knull 1934), syn. nov.
Also, joint ecological and distributional associations are presented for A. montosae, through the co-presence of A. pectoralis Waterhouse, A. near impexus Horn, A. pubescens Fisher and another buprestid, Chrysobothris lateralis Waterhouse.
