Type Material: Holotype worker, MADAGASCAR, Foret de Binara, 7.5 km 230° SW Daraina , 13°15'18"S, 049°37'00"E, 375 m, 1-4 Dec 2003 (coll. B. L. Fisher et al.), collection code: BLF09638, pin code: CASENT0498309 ( CAS).GoogleMapsCASC  Paratypes: 8 workers with same data as holotype but pins coded, CASENT104548GoogleMapsCASC  , CASENT0498310GoogleMapsCASCCASC1CASC2GB1GB2  , CASENT0498311GoogleMapsCASC  , CASENT0006944GoogleMapsCASC  , CASENT0006945 ( BMNH, MCZ, CAS)GoogleMapsCASC  ; CO1 Barcode from paratype collection and coded CASENT0498310-D01.

Worker measurements: maximum and minimum based on all specimens, n= 15, (holotype): HL 1.77-2.01 (1.92), HW 1.55- 1.81 (1.77), CI 86-92 (92), EL 0.35-0.43 (0.42), ML 1.04-1.15 (1.11), MI 56-66 (58), SL 1.68-1.97 (1.79) SI 101-109 (101), WL 2.52-2.89 (2.66), FL 1.85-2.17 (2.03), PW 0.92-1.06 (1.01).

Queen (ergatoid) measurements: maximum and minimum based on n = 5. HL 1.62-1.79, HW 1.49-1.65, CI 91-93, EL 0.37-0.41, ML 0.92-1.02, MI 55-59, SL 1.56-1.71, SI 99- 106, WL 2.33-2.55, FL 1.77-1.91, PW 0.88-0.99.

Worker Diagnosis: Blade of mandible with five teeth and denticles located at the distal halfofthe blade length. Petiole dorsal margin without spines. In front view, the dorsal petiolar margin flat with lateral margin rounded (Fig. 6b). Pilosity, sculpture as in Figures 2e,f.

The species is most similar to A. boltoni  HNS  but can be easily distinguished by its petiole node without apical spines.

No winged queens are known. Ergatoid queens were collected at six localities. In four of the collections, three ergatoid queens were collected in the same locality. They are very similar in size and shape to workers (Figs 2g,h), and have no ocelli (Fig. 2g). Males are not known.

Distribution and biology. A. goodmani  HNS  is endemic to Madagascar and is widespread in northern and western parts of the island. It has been collected in dry forest and rainforest as low as 30 m in altitude and also in montane rainforest at the altitude 960 m on Montagne d'Ambre (Fig. 6a), most frequently under stones (12 collections) and sifted litter (7), but also at light (1), beating low vegetation (3), rot pocket (1), in rotten log (6), ground foragers (1), ground nest (9), Malaise trap (1), on low vegetation (1), and pitfall traps (4).

CO1. Average iIntraspecific sequence divergence of 6.37%. There is strong geographic coherence in the divergence patterns (Figs 9, 15, Table 2) with deep divergences occurring between separate regions isolated by habitat and mountains.

Diagnostic barcoding loci. A. goodmani  HNS  : Y-231 ( madagascarensis  HNS  and grandidieri  HNS  A; boltoni  HNS  and pattersoni  HNS  T), W-233 (all others A), RWR-368-370 (others are all ATG), Y-541 (others are all T), R-543 (others are all A), W-546 (others are all T), W-585 (others are all T), M-634 (others are all C). RWCW-42-45 & WTTAG-66-70 (this distinguishes goodmani  HNS  from all (including boltoni  HNS  ) except some madagascarensis  HNS  ), & GT-83-84 ( madagascarensis  HNS  is TA).

Discussion. Anochetus goodmani  HNS  is characterized by extreme divergence within the barcode region. To date, sequencing complementary nuclear markers has provided some degree of support for the deepest CO1 divergences (between the north and south-west of Madagascar) as being separate species. Importantly however, ITS1 sequences as divergent have been produced from the same individual (Appendix S1 and Table 3). Although CO1 supports more than one operational unit within A. goodmani  HNS  the hypothesis of cryptic species in relatively isolated environments requires further evidence with less ambiguity.
