ABSTRACT

 

The present study on the chrysomelid beetles of the subfamily Galerucinae from Sarawak has recorded an impressive number of species. There are 181 species, in 53 genera, greatly increased from the previous records. 38% of the total species are represented by single specimens. The four most widely distributed species are Monolepta impressicollis Jacoby, Theopea elegantula Baly, Mimastra sumatrensis Jacoby and Monolepta marginicollis Jacoby. The Galerucinae are distributed unevenly in all localities surveyed, with nearly 75% of the species restricted to one locality, and the other 25% shared with at least two localities. The distribution pattern of the Galerucinae shows many facets of vegetation in the rainforest of Sarawak. The gazetting of the proposed areas that have been identified as new National Parks and Wildlife Sanctuaries is most welcome.

 

ABSTRAK

 

Kajian kini terhadap kumbang Chrysomelidae daripada subfamili Galerucinae dari Sarawak mencatatkan bilangan spesies yang sangat menarik. Terdapat 181 spesies, dalam 53 genus, bilangan yang sangat meningkat berbanding dengan rekod terdahulu. 38% daripada jumlah spesies adalah diwakili dengan satu spesimen. Empat spesies yang meluas taburannya adalah Monolepta impressicollis Jacoby, Theopea elegantula Baly, Mimastra sumatrensis Jacoby dan Monolepta marginicollis Jacoby. Taburan Galerucinae adalah tidak sekata dalam semua lokaliti yang ditinjau, yang mana 75% spesies tertumpu dalam satu lokaliti, manakala selebihnya, 25% adalah berkongsi sekurang-kurangnya dua lokaliti. Pola taburan Galerucinae menunjukkan pelbagai faset vegetasi hutan hujan Sarawak. Mewartakan kawasan-kawasan yang telah dicadangkan untuk Taman Negara dan Sanktuari Hidupan Liar adalah sangat dialu-alukan.
