| patterns of postmating reproductive isolation in a newly discovered species pair, aquarius remigis and a. remigoides (hemiptera;gerridae). | aquarius remigoides gallant and fairbairn has recently been described as specifically distinct from a. remigis (say) based upon genetic and morphological data. both species are common, semiaquatic bugs (hemiptera; gerridae) found on the surface of streams and small rivers. allozyme studies have shown them to be more distantly related than most other congeneric species in the gerridae, with significant barriers to gene flow where their ranges abut. we assess postmating reproductive isolation betw ... | 1997 | 9203351 |
