After the revision (here), the name of this species was changed as Trirachys indutus (Newman, 1842).
The true Aeolesthes have spined knees like Eburia spp. |

Ok, Aeolesthes induta is right!
Regarding Trirachys, I also noticed that some Aeolesthes-species are sometimes sold with such name; nonetheless, Trirachys orientalis has a distinct spine at each side of the prothorax (here) and a more northern distribution (Laos, China, Japan).
Actually, both genera need a revision. |

The furrow you mention corresponds to Fig.2, without any doubt. So this designs Aeolesthes induta.
I had received two of these specimen with the determination "Trirachys orientalis". |

For these species, it is necessary to check the ventral side of the head.
If the intergenal furrow is right (Fig. 1), it is Aeolesthes holosericea (Fabricius, 1787), if backward bowed (Fig. 2), it is A. induta (Newman, 1842).
Both species are largely present in Eastern Asia, Malaysia... and in the gallery (here);-)
I guess induta. |
