Barney, Robert J., 2019, Key to All Sixty-Four Species of Pachybrachis Chevrolat (Coleoptera: Chrysomelidae: Cryptocephalinae) in the Eastern USA, The Coleopterists Bulletin 73 (1), pp. 85-96 : 95

56. Pachybrachis subfasciatus (J. E. LeConte,

1824) ( Neotype in INHS) .

Barney 2017a: figs. 1, 9A–D; map 1A.

Synonyms. Pachybrachys biguttatus Suffrian, 1852 (Type unknown); Pachybrachys impurus Suffrian, 1852 (Neotype in TAMU); Pachybrachys xanthias Suffrian, 1852 (Type unknown, uncertain

application); Pachybrachys impurus var. umbrosus Fall, 1915 (Holotype in MCZ) .

Type Material. A recently discovered female in BMNH, labeled “ Texas [printed, green paper] // Type / Suffr / Coll. / Deyrolle // Pachybrachys / impurus / Suffr / N. America [hand-inked, tan paper] // Baly Coll. [printed, white paper],” is a possible Suffrian lectotype .

Remarks. Species treated in the revision of the luridus species-group ( Barney 2017a) were inadvertently reported with the pronotal length (PL) and pronotal width (PW) reversed. The correct measurements for P. subfasciatus are PL = 0.58–0.74 mm and PW = 0.87–1.04 mm.

A virtually all black specimen of P. subfasciatus was found in the BYUC and is labeled “ WEST VIRGINIA, Grant Co. / 2.3 km NNW Landes / Cave Mountain, 38°54 ʹ 78 ʹʹ N, / 79°12 ʹ 83 ʹʹ W, alt. 2190 ft., / 8-VI-2001, R. A. Androw.”
