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 mmin pattersoni,HL+ML< 1.75 mmin 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[e.g. Forel 25:159] most likely refer to this species. No other species of Anochetushave been recorded from the Seychelles. Males have been collected in Malaise traps, and a queen with clear wing scares.  Diagnostic barcoding loci: A. pattersoni: G-183, G-264, A- 399, A-489, A-505, A-552.  Additional material examined for Anochetus pattersoni: In addition to the typematerial, specimens from the following localities were examined in this study.  Seychelles: Aldabra Group: South Island( Grand Terre), Dune Patates  5- Jun-74(Coll: V.
