Bolton and Fisher (2012) report: Although described as a Simopone species, and reportedly having 11 antennomeres, huode is radically different from any other species examined in this study. We are convinced that this species is not correctly placed in Simopone. From the original description and drawings, and the rather poor photographs of the holotype available at www.niaes.affrc.go.jp, there appear to be 12 antennal segments, the scape is far too long and the eyes are too far forward (although the two eyes are at different levels in the drawing). In addition, the frontal carinae are close together, truncated posteriorly and terminate immediately behind the frontal lobes, as is usually seen in Cerapachys but never in Simopone. The antennal sockets appear almost entirely exposed, the posterior margin of the head and its corners are too rounded, an occipital surface is present, AII (petiole) is not laterally marginate, and the prora appears to have the wrong shape. In the illustrations it is impossible to see the condition of the mesotibial spurs (stated as absent in the description but may have been abraded away or overlooked in the poorly mounted specimen) or whether the pretarsal claws are toothed. Finally, the presence of a metabasitarsal glandular groove is not recorded. Until the holotype can be critically re-examined this species should be regarded as a member of genus Cerapachys (sensu lato).

Head long, 1.17 times as long as wide, with straight posterior margin and convex sides in full face view, posterolateral corner forming a dull angle; frons and vertex moderately punctate. Antenna with 11 segments; scape short, SI - 42; 10th segment as long as wide, terminal segment twice as long as wide. Mandible broad triangular. Eye large and prominent, 0.23 mm in maximum diameter.

Alitrunk with almost straight dorsum. Petiole longer than high, with broadly convex dorsal outline in profile; in dorsal view, dorsal disk slightly wider than long, with concave anterior margin, convex posterior margin, and weakly convex and angulate posteroventral corners. First gastral tergum 0.25 times as long as wide, 0.50 mm in maximum width in dorsal view. Fore wing 2.3 mm in length.
