Principal component, and canonical variate analysis based on six characters show that there are morphological differences between three Laonice forms (L. bahusiensis, L. sarsi, and Laonice sp.). This supports Söderström's division of L. cirrata into four species; a decision often questioned by other taxonomists. We cannot exclude the possibility that the morphological differences are caused by polymorphism or seasonal variation within a single species. There is, however, no information to vindicate this and we conclude that the three forms should be regarded as separate species until this hypothesis can be rejected.
