Similar appearances with distinct genitalia or vice versa? the case of Afissa (Coccinellidae, Epilachnini) from West Java, Indonesia

New beetle was discovered in the mountainous region of Bandung, West Java, that fits the description of Afissa . The physical appearance is similar with Afissa gedeensis while the male genitalia is identical with Afissa incauta . The aim was to clearly assess the situation by observing the biology of this novel Afissa and to compare the data with known Afissa gedeensis . A . sp. cf. gedeensis has slightly smaller and duller body with minor difference in elytral maculation. The male genitalia have more curved penis guide with distantly separated from paramere. Preference and acceptance test shows this beetle isolated by divergent host plant specialization. We proposed three possible interpretation including the newly recorded variation (host race) of A. gedeensis , A. incauta , or this beetle is genuinely new species.
