REVIEW OF THE GENUS LIENETIS FROM LAOS COLEOPTER A. LYCIDAE)
Libnetis WATER HOUSE l8J8 contains over 60 species and is the largest genus of Libia etini. Iis distribution is predo minantly limited to the Oriental Region with sonae transcende iace to the Palaearctic Region - Japan, Taiwan, fouthern
2000) who appended other Species. LibnetiS encompasses small, yellow to brown Species having pronotum witha slight median longitudinat carina in the anterior half, on the elytra only primaryCOStae pre Sent, Secondary cOStae and reticulate celis absent. The genus is stronglyhomogenous in externat characters. Conversely, diversification of male genitalia is Very high, and therefore, the taxonomy of Libnetis is based on genitalia in a large extent. These characters are osten in hi gli congruence with the s hape of mouthparis e specially mandi bies and terminal palpomeres of both palpi), and caia be used as a basis for inferring the relation ShipS.
Specimens were examineci and illustraled using an Olympus SZX-l2 stereoscopic micro- Scope, with the magnification up to 90κ, and illustraled using pictures made by an Olympus DP-lo digital camera.
