title: Chromosome key to the larvae of the Simulium metallicum complex (Diptera: Simuliidae) from Latin America.
abstract: A key based on larval salivary gland polytene chromosome inversions is presented for 11 members (species A-K) of the Simulium metallicum Bellardi complex from Latin America. Most members (B, D, E, G, H, I, J, and K) can be distinguished from the cytological standard, sibling A, solely on the basis of fixed inversion differences. A suite of characters (sex-linked inversions as well as polymorphisms) must be examined to separate cytotypes C and F from A.
