Abstract
Amblyseius filcae Denmark and Villanueva, n. sp. was found on Viburnum odoratissimum Ker Gawl. var. awabuki (K. Koch) Zabel (Caprifoliaceae) in Florida. The adult female can be identified by its rosy coloration, and, on permanent slides, by its tubular-fundibular spermathecal calyx 15 μm long and nodular atrium. Developmental times on pollen of crocea iceplant (Malephora crocea Jacquin) (Alzoaceae) were 60.6 ± 1.3, 32.2 ± 1.3, 41.3 ± 1.0, 29.6 ± 1.6, 54.7 ± 1.4, 218.7 ± 3.3 h for eggs, larvae, protonymphs, deutonymphs, preoviposition time and total female developmental time (up to first oviposition), respectively. Amblyseius filcae showed a weak or no predatory performance on Phyllocoptruta oleivora (Ashmead) and adult female Brevipalpus phoenicis (Geijkes) during predator-prey laboratory bioassays, but B. phoenicis egg predation was observed.
