Primary type information:
Primary type material: lectotype worker (by designation of Snelling, 2000: 608). Primary type locality: lectotype Mexico: Veracruz, Mts of Orizaba (Sumichrast). Primary type depository: MHNG.
Secondary type information:
Secondary type material: 2 paralectotype workers. Secondary type locality: same as for lectotype. Secondary type depository: MHNG.
Type notes:
1) Lectotype designation by Mackay & MacKay, 1997b: 332, is redundant as the specimen they cite is derived from Forel, 1895a: 44 (in text), from Guatemala, not from the original type-series from Mexico. 2) Forel, 1879a: 82, cites a Norton syntype in NHMW.
