Gryon fervidum Mineo, 1992: 18 (original description). Comments. The original description is brief, and characters needed to properly place this species are largely absent. We interpret "from upper margin of the frontal depression and because there is no ridge connecting the latter to anterior ocellus" to refer to a carinate margin of the frontal depression, as is seen in Hadronotus ancinla ( Chen et al. 2020 ), and which may be connected to the anterior ocellus by a carina. Mineo (1992) placed G. fervidum in the Gryon hiberus group, but the description of the Gryon hiberus group by Mineo (1990b) is also brief and insufficient for generic placement. We examined the holotype of Hadronotus lucmon , described as Gryon lucmon concomitantly with G. fervidum , which was also placed in the Gryon hiberus group and which belongs in Hadronotus . Our examination of a paratype specimen also supports placement of this species in Hadronotus . Figures 88-91.
