Xylosandrus discolor, is a species of weevil found in Australia, Micronesia, Myanmar, China, India, Sri Lanka, Indonesia, Malaysia, Taiwan and Thailand.[1][2][3]

Description

Body length of the female ranges from 1.8 to 2.0 mm. Body bicolored. Pronotum light brown. Elytra dark brown. Antennae and legs are yellowish brown. Antennea with 5 funicular segments and obliquely truncate club. Pronotal vestiture of erect and hairy setae. Pronotal base covered with a dense patch of short erect setae. Pronotal disc is densely asperate-punctate. Pronotum consists with lateral costa and carina. Protibiae with 4 to 5 socketed teeth, whereas mesotibiae and metatibiae with 8 to 9 socketed teeth. In elytra, discal striae and interstriae multiseriate is punctate. Diclivital elytral face is steep and abruptly separated from disc. Elytral striae coarsely granulate with appressed hairy setae.[4]

A polyphagous species, it is found in many plants.[4][5] It is primarily a shoot borer.[6]
