Differential diagnosis. Laccobius jaechibelongs to the group of species with unordered elytral punctures and curved hind tibiae. Within this group it resembles L. eliogentiliiand L. pluvialis sp. nov.by the pale spots and stripes on elytra. It is chiefly distinguishable from them by the shape of the aedeagus ( Figs. 20-22) with the phallobase nearly as long as the parameres. Externally, it differs from the latter two species by smaller black elytral areas leaving four pale spots near base and longitudinal stripes in the posterior half.
