heteromerous

Rhipiphorus, rī-pif′o-rus, n. a genus of heteromerous beetles.

Heteromerous: having an unequal number of tarsal joints on the feet.

Legs heteromerous, four claws to each tarsus, two of them larger than the others, and minutely serrulate on the inside.

In a large number of the Heteromerous beetles, they are set transversely, in the Capricorn ones longitudinally.

Heteromerous insects are those in which the number of these joints varies in the different pairs of legs.
