Taxonomic History (provided by Barry Bolton, 2023)

Typhlopone pallipes Haldeman, 1844 PDF: 54 (w.) U.S.A. Nearctic. Primary type information: Type-material: syntype (?) workers. Type-locality: U.S.A.: (no further data; the only information supplied is “found in old stumps in June”). Type-depository: unknown (no type-material known to exist). Type notes: 1) No indication of number of specimens is given. 2) Creighton, 1940b PDF: 4, comments that he examined two ‘autotypes’ that had been sent by Haldeman to Harris, which were deposited in the Boston Society of Natural History (now MSBM). While not syntypes, these were probably specimens collected and identified by Haldeman himself. AntCat AntWiki HOL

Distribution Notes:



Mesic woodlands in soil and leaf litter.


Worker: inner border of mandible and anterior clypeal margin broadly convex in outline; California specimens smaller in size than those of A. oregonensis (HW 0.99-1.15), with narrower heads (CI 0.86-0.90).


The differences in worker size (HW) and head shape (CI) between Amblyopone oregonensis and California A. pallipes break down when considering A. pallipes workers from eastern United States.
