Remarks.

The abdomen of Gasteracantha rubrospinis is wider than long. This species can be distinguished from other Thai Gasteracantha by characteristics of their spines and the color pattern on the dorsal abdomen. The abdomen is bright yellow, with a large and incomplete horizontal black transverse band near the anterior edge. The abdominal spines are wider at the base, tapered toward the tip, and ending with a sharp point ( Guérin 1838; Simon 1877; Pocock 1897). The reported specimens of G. rubrospinis from Thailand belong to Pocock’s collection ( Pocock 1897). The locality was listed as “Patani” [= Pattani Province], the southernmost province of Thailand. No specimens were obtained in this study.
