First record of leaf-hole shelters used and modified by leaf beetles (Coleoptera, Chrysomelidae), with descriptions of two new Orthaltica Crotch species from southern India

Collection: Pensoft Publishers

Keywords: Leaf-hole shelter · Topics: Coleoptera Taxonomy and Distribution, Coleoptera: Cerambycidae studies, Lepidoptera: Biology and Taxonomy

Behavioural novelties observed in adult leaf beetles of two new Orthaltica Crotch species include: 1) the use of low cost leaf-hole shelters, either in pre-formed holes produced by larger beetles that fed on the same leaf, or artificially created holes as part of an experiment; and 2) the use of faeces to partition the hole. Two new southern Indian species of the genus Orthaltica are described and illustrated: O. syzygium and O. terminalia. Host plants are identified for both species. A key to the Indian species of Orthaltica is provided.
