1	Outer parts of metasternal disc mostly free of setae; isolated latero-posterior setose patches or lateral extensions of anterior setose margins present in some species and widely scattered single setae may present on unworn individuals	3
-	Outer parts of metasternal disc or its lateral side mostly covered with dense setae; other characters variable	2
2	Internal sac of aedeagus with posterior part of dorsal sclerite in lateral view directed ventrally	Lilioceris cheni Gressit & Kimoto
–	Internal sac of aedeagus with posterior part of dorsal sclerite in lateral view directed dorsally	Lilioceris unicolor Hope
3	Outer parts of metasternal disc without isolated posterior setose patches	4
–	Outer parts of metasternal disc with isolated posterior setose patches; pronotum with scattered large punctures, elytral punctures not weakened posteriorly, elytral interval in pre-apical area distinctly convex	Lilioceris impressa (Fabricius)
4	Pronotal disc completely covered with scattered large punctures	5
–	Large punctures on pronotal disc present only as a row along mid-line, at least on anterior half, the rest of the disc utmost with only some tiny punctures	6
5	Elytral punctures on posterior third not weakened, more or less the same size and depth as on anterior half; pronotum posteriorly with single weak, regularly transverse impression; posterior part of dorsal sclerite of aedeagus in dorsal view directed laterally (Fig. 29)	Lilioceris thibetana (Pic)
–	Elytral punctures on posterior third variably, but distinctly, weakened; pronotum posteriorly with two weak, but distinct transverse irregular impressions; posterior part of dorsal sclerite of aedeagus in dorsal view directed medially (Fig. 27)	Lilioceris laosensis (Pic)
6	Occipital area with shallow furrow sometimes reduced to deep small fovea at midpoint; elytral intervals in preapical area flat	7
–	Occipital area without longitudinal furrow, only with weak impression and thin, indistinct suture; elytral intervals in preapical area distinctly convex	Lilioceris egena (Weise)
7	Anterior setose fringe of metasternum expanded on antero-lateral corner; lateral side of pronotum around constriction impunctate; most of metepisternal disc densely covered with setae	Lilioceris malabarica (Jacoby)
–	Anterior setose fringe of metasternum narrow, not expanded; lateral side of pronotum around constriction with several large punctures; setae on metepisternal disc present only as narrow strip along inner margin	Lilioceris yunnana (Weise)
