23. Pachybrachis femoratus (Olivier, 1808) (Neo-

type in MCZ ).

Barney 2017a: figs. 3, 9E –F; map 1B.

Synonyms. Cryptocephalus sparsus Newman 1840 (Type unknown); Pachybrachys characteristicus Suffrian 1852 (Lectotype in MNHUB); Pachybrachys femoratus var. aquilonis Fall 1915 (Holotype in MCZ).

Remarks. A potential type specimen of C. sparsus , labeled “ Type / H. T/ [circular white disc with red border] // 82 / Cryptocephalus / sparsus Newman [hand-inked, blue paper]”, was recently discovered at BMNH. Unfortunately, no definitive confirmation can be made as the head, prothorax, and left elytron are missing.

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. femoratus are PL = 0.60–0.72 mm and PW = 0.89–1.03 mm.
