FIGURE 29. Photographs of diagnostic characters to distinguish between workers of Veromessor lariversi Smith and (A–C) V. pseudolariversi (D–F). Photographs of V. lariversi worker (CASENT0923148): (A) anteroventral margin of postpetiole lacking a minute process, margin with a continuous profile, and (B) in profile and (C) in dorsal view, pronotum and mesonotum arugose and weakly to strongly coriarious to punctulate-granulate. Photographs of V. pseudolariversi paratype worker (CASENT0923121): (D) anteroventral margin of postpetiole with a minute process that interrupts the continuous profile, margin weakly concave anterior to process, and (E) in profile and (F) in dorsal view, pronotum with discontinuous to continuous, wavy to irregular transverse rugae; dorsum of mesonotum with one to few weak, wavy to irregular, usually discontinuous longitudinal rugae.
