Nesomyrmex simoniHNS (Emery, 1895)

Fig. 1m -o

Tetramorium simoni EmeryHNS, 1895b: 35. For type information and synonyms, see Bolton (1982).

Description of worker

HL 0.924-1.021, HW 0.783-0.884, HW1 0.850-0.915, CI 83-87, SL 0.649-0.688, SI 78-83, PW 0.615-0.672, ML 1.168-1.268, EL 0.258-0.266, EI 29-33 (3 of 3 measured).

Description matches that of Bolton (1982) except for a few additional characters: promesonotal dorsum with scattered short erect hairs, petiolar node with a pair of subdecumbent hairs and a pair of subdecumbent hairs on the postpetiole; sparse pubescence present.

Diagnosis

Nesomyrmex simoniHNS looks similar to N. braunsiHNS and N. saasveldensisHNS in that they all have rugo-reticulate petiolar node and rugo-reticulate sculpture is usually also evident partially or completely on head and mesosoma. It is recognized from N. braunsiHNS by its smaller size (HW 0.783- 0.884 versus 1.033-1.109), and armed propodeum (versus unarmed). It is distinguished from N. saasveldensisHNS by lacking hairs on the propodeum.
