Anochetus pattersoni Fisher   ZBK   HNS sp. nov.

Figures: worker 7a-d; queen 7e,f; male 7g,h, 8d

Type Material: Holotype: worker, Seychelles Aldabra Group, Picard Island , in old "Settlement" 09°23'34"S 046°12'14"E 5 m, mostly Casuarina with coco palms, exotic vegetation, found after dark on concrete slab in abandoned settlement 19-Dec-05 (coll. S.M.Goodman) collection code: SMG14998 CASENT0068352 1w ( CASC) GoogleMaps CASC CASC1 GB1 . CO1 barcode from same collection as holotype and labeled CASENT0068352-D01 GoogleMaps CASC CASC1 GB1

Worker measurements: maximum and minimum based on all specimens, n = 8, (holotype): HL 1.32-1.40 (1.40), HW 1.25- 1.31 (1.31), CI 93-95 (94), EL 0.20-0.26 (0.23), ML 0.67-0.72 (0.72), MI 50-51 (51), SL 1.07-1.15 (1.15) SI 85-88 (88), WL 1.62-1.79 (1.78), FL 1.11-1.20 (1.19), PW 0.70-0.76 (0.74).

Queen measurements: maximum and minimum based on n= 1. HL 1.31, HW 1.29, CI 99, EL 0.30, ML 0.64, MI 49, SL 1.05, SI 81, WL 1.81, FL 1.15, PW 0.79.

Male measurements: maximum and minimum based on n = 2 from Madagascar: HL 0.86-0.87, HW 1.07-1.10, CI 124- 126, EL 0.65-0.67, SL 0.18, SI 17, WL 1.72-1.77, FL 1.21-1.26

Worker Diagnosis: Dorsal margin of petiole node concave medially (not visible in figures of the workers but easily seen in the queen in Figure 7f.) Anterior portion of pronotal dorsum lightly sculptured compared to posterior portion of pronotum. Propodeal dorsum and angle transversely coarsely rugose, declivitous face below angle with transverse striae, with sculpture thinning near base of face; propodeum angulate in lateral view. Petiole scale broad; anterior half of first gastral tergum smooth and shiny with only fine punctures at base of setae. This species is most similar to the graeffei a widespread species across the Indo-Pacific, but differs from the latter by the pattern of sculpture on the mesosomal dorsum, shape the petiole (concave), broader petiole node as seen in lateral view, and its much larger size (HL+ ML 1.99-2.12 mm in pattersoni   HNS ,HL+ML<1.75 mm in graeffei).

Distribution and biology. This species is limited to the Aldabra group islands with most collections from Isle Picard. References and records to Anochetus madagascarensis   HNS [e.g. Forel 25:159] most likely refer to this species. No other species of Anochetus   HNS have been recorded from the Seychelles. Males have been collected in Malaise traps, and a queen with clear wing scares.

Diagnostic barcoding loci: A. pattersoni   HNS : G-183, G-264, A- 399, A-489, A-505, A-552.
