Diagnosis
Occipital area with shallow furrow, at least with deep small fovea at midpoint. Pronotum posteriorly with single weak, regular, transverse impression. Pronotal disc with scattered larger punctures, mid-line alignment of punctures usually still evident, at least on anterior half. Lateral side of pronotum around constriction with large punctures. Outer metasternal disc only with oblique setose patch. Anterior setose fringe not expanded in antero-lateral corner. At least half of metepisternal disc covered with setae. Apical elytral punctures strong. Apical elytral intervals distinctly raised. Internal sac of aedeagus with posterior part of dorsal sclerite in dorsal view elongate, narrowing posteriorly, directed slightly laterally. Posterior part of dorsal sclerite in lateral view widening and round at apex, directed forward.
Comments
All five species put here into synonymy with Lilioceris impressa correspond to it well. There is slight variability in the size of the outer metasternal setose patch, and color varies from almost completely reddish-brown to typical black and yellow, but pronotal and elytral punctuation and sculpture as well as aedeagus characters are consistent between specimens. We did not observe any meaningful variability in the shape of the expanded distal antennomeres, which was used by Gressit and Kimoto in describing Lilioceris inflaticornis and Lilioceris laticornis. However, even these authors had some doubts about the use of these characters, even in the reference to the type series (Gressit and Kimoto 1961[4]).
We did not thoroughly search for Lilioceris impressa-group specimens originating from outside of the area of interest, in particular from the islands and archipelagoes of the Oriental Region. However, all the island specimens in the USNM identified as Lilioceris impressa do not belong to this species and all lack the outer metasternal setose patch. So, the prevailing concept of Lilioceris impressa, being widely distributed across almost the entire Oriental Region, seems to be at least questionable. All the USNM Lilioceris impressa-group specimens originating from Sri Lanka, Andaman Islands, Greater and Lesser Sunda Islands, and Philippines were not identified as any of the species dealt with in this study and might indeed represent undescribed species closely related to other Lilioceris impressa-group species.
