WORKER (holotype in parentheses). Measurements: HL 0.52 – 0.54 (0.52), HW 0.38 – 0.40 (0.40), HS 0.415 – 0.470 (0.460), SL 0.32 – 0.34 (0.34), PrW 0.28 – 0.30 (0.29), WL 0.67 – 0.70 (0.67), HFL 0.32 – 0.34 (0.32), PeNL 0.14 – 0.16 (0.15), PeH 0.28 – 0.30 (0.29), PeNW 0.20 – 0.23 (0.21), PeS 0.210 – 0.230 (0.213) (10 measured). Indices: CI 72 – 77 (77), SI 83 – 89 (85), PeNI 70 – 78 (72), LPeI 47 – 55 (52), DPeI 133 – 144 (140).
Eyes absent or at most with an indistinct small depigmented spot. In full-face view apex of scape, when laid straight back from its insertion, distinctly fails to reach the midpoint of the posterior margin; SL/HL 0.62 – 0.65. Reticulate-punctulate sculpture of cephalic dorsum fine; head more densely sculptured than pronotal dorsum. Lateroventral surfaces of head almost smooth, only with very widely separated, minute punctulae. With mesosoma in dorsal view the metanotal groove absent. Propodeal declivity separated from sides by blunt angles or weak marginations . Mesopleuron smooth and shining. Petiole in profile with the node relatively short and of moderate height, the anterior and posterior faces parallel or at most extremely feebly convergent dorsally; dorsal surface shallowly broadly convex. Subpetiolar process usually with a low, blunt ventral angle. Posterior surface of petiole node without a transverse groove or impression above the peduncle, but sometimes a slender transverse carina is present that is immediately adjacent to the peducle. Without cuticular ridges that radiate upwards from the posterior petiolar peduncle. In dorsal view the petiole node distinctly broader than long. Maximum width of first gastral tergite in dorsal view less than the width of the second tergite at its midlength. Base of cinctus of second gastral tergite with short, feeble and indistinct cross-ribs that often appear merely as a row of aligned weak punctures. Posttergite of second gastral segment, from posterior margin of cinctus to apex, distinctly broader than long. Disc of second gastral tergite shallowly reticulate-punctate to microreticulate. With first gastral segment in profile its dorsum with sparse short standing setae. Full adult colour yellow to yellowish brown.
Holotype worker, South Africa: Kwazulu Natal, Umtamvuna Nat. Res., 31°02.704 ’ S, 30°10.080 ’ E, 220 m., 15.xi.2000, Winkler bag extraction, leaf litter, Pondoland Coastal Plateau, sour grassland, KW00-W23, CASENT 0395928 (S. van Noort) (CASC).
Paratypes. 3 workers and 1 delalate queen, with same data as holotype but coded KW00-W24, CASENT 0395317; KW00-W25, CASENT 0395327; KW00-W25, CASENT 0395328; KW00-W25, CASENT 0395330 (queen) (CASC).
The series from South Africa, Gauteng Prov. (data below, in SAMC, AFRC, BBRC) is extremely close to meridiaHNS and fits the above description except for being slightly darker and slightly larger than other series examined , but the LPeI in this series is consistently somewhat higher. Measurements: HL 0.54 – 0.56, HW 0.41 – 0.42, HS 0.475 – 0.490, SL 0.34 – 0.36, PrW 0.32 – 0.33, WL 0.68 – 0.70, HFL 0.35 – 0.36, PeNL 0.18 – 0.20, PeH 0.30 – 0.32, PeNW 0.24 – 0.25, PeS 0.240 – 0.257 (9 measured). Indices: CI 73 – 77, SI 82 – 86, PeNI 75 – 78, LPeI 58 – 65, DPeI 125 – 139. Besides this, the cross-ribs at the base of the cinctus of the second gastral tergite are extremely feeble and appear undeveloped in a few specimens; even at their strongest the cross-ribs appear as a row of minute, feeble punctures that may be difficult to see. This Gauteng series is currently maintained as meridiaHNS because it is by no means certain that separation at species-rank can be justified. The species is run out at two places in the key to reflect the variation of development of the gastral cross-ribs. See also the notes under natalensisHNS.
