Mandibles with longitudinal striations. Clypeus with longitudinal striations, with central and posterior region of median portion smooth to faintly reticulate. Anterior clypeal margin evenly convex and with a projecting translucent lamella medially. Large eyes with 16 ommatidia in the longest row. Scapes of moderate length (SI 85). Head in full face-view hind margin shallowly convex. Promesonotum in profile evenly convex and metanotal groove conspicuously impressed.Propodeumunarmed;forminganevenconvexity with declivity. Anterior peduncle with a small tooth-like subpetiolar process. Petiolar node in profile evenly convex; posterior to the node is a moderately broad cylindrical portionof the petiole. Postpetiole inprofile low and rounded. Dorsumofhead with faint reticulate pattern and faint longitudinal striations between the eyes and behind the antennal insertions. Promesonotum finely reticulate, propodeal dorsum reticulate-punctate. Petiolar node and postpetiole finely reticulate pattern. First gastral tergite with a very short basal costulae and the rest of the tergite smooth and shining. Dorsum of head with short erect hairs mostly concentrated along two longitudinal lines. The venter of head with five straight hairs and two curved hairs. Promesonotal dorsum with at least four pairs of short, erect hairs, acute apically. Propodeum with two pairs of erect hairs, petiolar node with two pairs of suberect acute hairs apically and postpetiole with two pairs of suberect hairs. Regularly spaced suberect hairs on the gastral tergite and sternite. Head and gaster dark brown, with mesosoma and nodes light brown in colour. Paratypes.

Same as holotype except the following differences: Mandibles either with longitudinal striations or smooth and shining. Dorsum of head smooth or with faint reticulate pattern between the eyes; fine longitudinal striations between the eyes and behind the antennal insertions present. Promesonotum either finely reticulate, or smooth and shining, with a fine, barely evident, inlaid reticulate pattern. The venter of head with 3-5 long hairs. Promesonotal dorsum with 3-4 pairs of short suberect hairs. Base of first gastral tergite either with or without costulae.

Nesomyrmex nanniae Mbanyana & Robertson, 2008, sp. nov.
No full textNesomyrmex nanniae sp. nov. Fig. 3g -i Description of worker Holotype. HL 0.771, HW 0.590, HW1 0.624, CI 77, SL 0.514, SI 87, PW 0.452, ML 0.910, EL 0.232, EI 39. Mandibles with fine longitudinal striations. Median clypeus smooth and bordered by longitudinal striations. Anterior margin of projecting median portion of clypeus convex. Eyes large, with 15 ommatidia in the longest row. Head in full face view with hind margin shallowly convex. Scapes of moderate length (SI 87). In profile, dorsal margin of promesonotum evenly convex and confluent with dorsum of propodeum; metanotal groove absent dorsally but evident laterally. Dorsum of propodeum and declivity forming an even convexity in profile; propodeum unarmed. Metapleural lobes low and rounded. In profile, petiole with well-defined peduncle and large rounded node: anterior, dorsal and posterior margins together forming an even convexity. Subpetiolar process barely evident. Postpetiole in lateral view round and almost the same length as the petiolar node. Dorsum of head predominantly smooth and shiny with very faint, irregular striations; short irregular striations between the eyes. Promesonotum smooth and shining, with very faint irregular striations. Propodeum with fine transverse striations towards the declivity, elsewhere smooth with very faint irregular striations. Metapleuron and side of propodeum partially reticulate punctate. Both nodes dorsally more-or-less smooth with irregular faint reticulation. Sides of both nodes more heavily sculptured with irregular striations. Gaster smooth and shining, with irregular striations. A few long blunt hairs along posterior margin of the head and two longitudinal lines of hairs (at least four per line) posterior to the frontal lobes. The venterof head with one subdecumbent hair and sparse pubescence present. Promesonotum with a pair of erect hairs on the pronotal humeri and another pair further back. Propodeum with no erect hairs. Petiolar node with a single pair of suberect hairs, and postpetiole with three pairs of suberect hairs. Regularly spaced semi-erect hairs on gastral tergite and sternite. Head and gaster with sparse pubescence and occasional sparse pubescence on other surfaces. Colour uniformly dark brown. Paratypes. HL 0.656-0.747; HW 0.497-0.565; HW1 0.531-0.605, CI 72-76; SL 0.470-0.521; SI 90-96; PW0.370-0.420;ML0.757-0.870;EL0.187-0.207;EI35-40 (5 of 6 measured). Same as holotype except the mandibles are either smooth apically, with only longitudinal striations basally or entirely with longitudinal striations. Anterior clypeal margin either convex or more-or-less flattened medially. The venter of head with 1-3 subdecumbent hairs, sparse pubescence present. Hairs on the petiolar node range from 2-4 hairs. Diagnosis Nesomyrmex nanniae is similar in appearance to N. entabeni and N. ruani: they all have erect hairs on the promesonotum; propodeum forming an even convexity; and colour uniformly light brown. It is distinguished from N. ruani by the sides of petiolar node which have punctulate ground sculpture or at most a few weak rugulae. In dorsal view these feeble rugulae may persist, may fade out, or may be replaced entirely with reticulate-punctate sculpture but in no case does the entire node appear to be encircled with strong rugulae everywhere; in N. ruanisidesofpetiolar node are completely covered with strong, sometimes irregular, rugulae. In dorsal view the entire node with continuous rugulae around it. N. nanniae is also smaller (HW 0.497- 0.590; PW 0.370-0.452) than N. ruani (HW 0.644-0.690, PW 0.475-0.524). Nesomyrmex nanniae is separated from N. entabeni by the promesonotum and propodeum which are confluent in dorsal view, with no metanotal groove visible medially; in N. entabeni metanotal grooveisclearly defined and has short longitudinal rugulae. Biology Four specimens were collected from pitfall traps, one specimenfrom sweepingandtwospecimensfromyellow pan traps, all from Renosterveld on tillite in the Nieuwoudtville region. The fact that during the extensive sampling undertaken for the Conservation Project of the main vegetation types in the region, this species was only captured in Renosterveld on tillite, suggests that it is limited to this vegetation type. Etymology Named after Ingrid Nanni, who works for the South African National Biodiversity Institute (SANBI) and who capably managed the Conservation Farming Project that made the collection of these specimens possible.
