Diagnosis: Since a new species is added to the genus, it requires a new diagnosis to accommodate the newly described L. masumotoi sp. nov. This genus can be distinguished from other genera related to Omalodini by following characters: 1) body oval-shaped; 2) lateral pronotal stria abbreviated at base; 3) frons and epistoma impressed; 4) the margin of protibiae multispinulose, without any teeth; 5) all of the tibiae with one to two rows of setae on each side; 6) post metacoxal stria on first abdominal sternum present; 7) trochanter of forelegs with setae on anterior margin; 8) carinal striae of prosternum subparallel, converted at apex. 9) anterior margin of mesoventrite broadly and slightly curve outwardly; 10) pygidium longer than propygidium; 11) propygidium and pygidium covered with large and round punctures, separated by one to two times of its diameters.
