Name

Pachybrachis m-nigrum (F. E. Melsheimer, 1847)Wikispecies linkPensoft Profile

Recognition

Pronotum usually with thick, black, M-shaped marking; elytra yellow with variable black markings, but these usually leaving basal, lateral and sutural margins yellow, in addition to a basal and median yellow spots on each elytron (Habitus 8); male size medium: length 2.59 ± 0.11 mm, width 1.42 ± 0.07 mm.

Distribution

A typical eastern species distributed in the eastern half of the United States (Riley et al. 2003[1]). Its presence in the south of the eastern Townships, in Québec, corresponds to the northernmost limit of this species (Map 8).

Material examined

NEW BRUNSWICK: York Co., 15 km W of Tracy, off Rt 645, 45.6837°N, 65.8809°W, 22.vii.2007, red pine forest, sweeping foliage of Comptonia peregrina, R. P. Webster [1?, RWIC].
QUÉBEC: Châteauguay Co., Ormstown, 12.VII.1977, sweeping, E. J. Kiteley [1♀, CNC]; same data, except 30.VII.1978 [1♂, CNC]; Huntingdon Co., Covey Hill, 30.VI.1927, G. S. Walley [1♀, CNC]; same data, except 1.VII.1927, W. J. Brown [1♀, CNC].

Host plants

An old record by Schwarz (1890)[2] concerned Toxicodendron radicans (L.) Kuntze) (Anachardiaceae), but this was probably based on misidentified specimens of Pachybrachis tridens. Clark et al. (2004)[3] reviewed the literature. More recently, Webster swept it from Comptonia peregrina (Myricaceae) (Webster et al. 2012[4]). Recent surveying in Kentucky barrens/prairies by Barney et al. (2011)[5] cited Pachybrachis m-nigrum collected from and found to feed on St. John’s-wort, Hypericum dolabriforme Vent. (Clusiaceae) (Barney and Hall (2011)[5]).

Comments

Based upon external morphlogy, these specimens appear to be Pachybrachis m-nigrum. However, extensive dissections of material from across the eastern half of the US reveal an externally similar species, but with a distinctly different aedeagus, from the midwestern states (Barney, unpublished data).
