This species typically has conspicuous red markings on the posterior part of the mesopleuron, metapleuron, propodeum, and T I to T III (see Figures 14 A, B in Watanabe, 2020). However, I found a few specimens with reduced or absent red areas (Figs. 7 A– C). These specimens have red areas that are smaller in size, and the darkest specimen shows that the red area has changed to a yellow posterior area on T II (Fig. 7 C). In addition, the hind leg of a few specimens is conspicuously darkened (Figs. 7 B, C). Except for body colouration, the character states of these specimens agree well with those of normal specimens of <i>H. luica</i>. Thus, I conclude that these specimens represent a variation of this species.</p> |
