Leptothorax stramineus – Brown 1971: 4 . Nesomyrmex stramineus – Bolton 2003: 272 (see also Bolton 1982: 332 ; Mbanyana & Robertson 2008: 38 ). Diagnosis The following character combination distinguishes N. stramineus from the other species of the group: eyes with 7–9 ommatidia in longest row; in profile mesosomal dorsum with conspicuously impressed metanotal groove; propodeal spines relatively long and thin, several times longer than their basal width; in profile petiolar node high, rectangular nodiform, appearing around twice as high as long; in dorsal view petiolar node laterally denticulate; subpetiolar process without a long cuticular flange running back to the postpetiolar junction; dorsum of propodeum with standing hairs; first gastral tergite with standing hairs evenly distributed throughout. Diagnostic comments As pointed out above, N. stramineus is very close to N. denticulatus and N. innocens . For more details on its differentiation from them we refer to the species account of N. innocens . Biology Nesomyrmex stramineus was sampled in savannah woodlands and Afromontane forests, where it lives in dead wood on trees ( Mbanyana & Robertson 2008 ). Distribution This species occurs only in South Africa and Swaziland . It seems to be rather rare since it is only known from a few collection events.
