Morphological Variation of Longhorned Beetles (Coleoptera: Cerambycidae) from Subfamily Lamiinae

Longhorned beetle, Cerambycidae is among the most important economic wood boring insect, it interferes and brings damages to the forests including shade trees, fruit trees, nut trees, vegetable plantation, seeds, orchids, and flowers. Most of the longhorned beetles are from the subfamily Lamiinae with 20,036 species, covers 58% of the total longhorned beetles species. This study determined the species from subfamily Lamiinae in family Cerambycidae, records and elucidates the morphological variation using the voucher specimens of longhorned beetles under subfamily Lamiinae deposited in UNIMAS Insect Reference Collection (UIRC), Faculty of Resource Science and Technology (FRST) of Univerisiti Malaysia Sarawak. A total of 253 specimens of subfamily Lamiine consisting of 71 species representing 12 tribes, Ancylonotini, Apomecynini, Batocerini, Ceroplesini, Dorcaschematini, Homonoeini, Lamiini, Mesosini, Morimopsini, Pteropliini, Saperdini and Xylorhizini from were examined and recorded. The most abundant species recorded was Epepeotes luscus with 26 individuals (10.28% of total) and the most diverse genus was Glenea with 13 species recorded. The species were categorised into 13 clades based on their similarity on four external morphology characteristic
