Intraspecific Variation. This species is strongly vittate and varies greatly in size, from 2.40–3.80 mm.

Remarks and Comparative Notes. Lissorhoptrus longitarsis is similar to L. longipennis but differs in its distinct median broad black pronotal vitta and black elytral vitta, longer on the suture and slightly shorter in intervals 2 and 3, from base to near declivity, with remainder dark brown. In addition, the differences in the hind tibial mucro of the male support the validation of the change in rank to species. Another important fact for the change in rank is the widespread overlap in distribution, and this geographic sympatry also negates the rank of subspecies.

Biological Notes. No host is recorded, but the species has been taken at night in numbers from aquatic vegetation.

Distribution. From the Everglades to the North Florida Panhandle.

Standard length: 2.95 mm.

Intraspecific Variation. This widespread, commonly collected species is extremely variable in color. The most common pattern formed by the scale covering is a broad, black, median prothoracic vitta extending as a broad black fascia from the base of the elytra to the declivity. In many specimens, the color is almost uniformly gray or brown, and in some the only fascia is very narrowly angular and curved to an acute point just in front of the declivity. The length of the body is very variable and ranges from 2.00– 3.70 mm.

Remarks and Comparative Notes. Lissorhoptrus oryzophilus is very similar to L. simplex , but the latter has clearly apically projecting and medially emarginate elytra. This differs from L. oryzophilus which lacks projecting elytral apices and is truncate to round. Many specimens can be identified only through the differences in the hind tibial mucro of the males or the last tergite of the female with their very different apical emarginations.

Biological Notes. This species is a serious pest of introduced commercial rice. The biology of the weevil is reported in detail by Bowling (1972). In summary, the eggs are placed in the submerged leaf sheath, the larvae feed there briefly and then emerge and drift down to the mud, where they move to the roots. As they grow, they move through the mud to feed on the roots. Using five sets of spiracles on paired hooks on the dorsum of abdominal tergites II-VII, they penetrate and tap the roots for oxygen, unhook, and move through the mud to feed on other roots. The larvae form a silken cell encrusted with mud attached to the roots underwater and in the mud and pupate within this waterproof cell. Adults emerge and overwinter in grass clumps and leaf litter.

Distribution. Native to the USA (eastern USA to TX, Great Plains, and California); also in Mexico, Cuba, China, India, Italy, Japan, Korea, and Taiwan.
