Diagnostic characters of adult female

  • Dorsal shield ca. 0.320–0.330 mm long
  • Dorsal shield setae j5 and S5 both present, j5 short and not reaching insertion of j6; j6 simple and shorter than Z1; R1 and r3 simple, similar in length.
  • Peritrematal shield fused to dorsal shield anteriorly
  • Fixed digit of chelicera elongate and with row of 7–9 teeth
  • Calyx of spermatheca funnel-shaped
  • Sternal shield with 3 pairs of setae; st4 on small platelets.
  • Anal opening on ventrianal shield with 5 setae
  • Setae JV2 on subpentagonal to subcordate ventrianal shield and JV4 in soft cuticle
  • Genu IV with simple macroseta (ca. 0.060 mm long); macroseta on basitarsus IV simple (ca. 0.086 mm long)

Similar species

Phytoseiulus longipes has a sternal shield with only 2 pairs of setae (st1–2) and lacks dorsal shield setae j5 and S5. Phytoseiulus macropilis usually has an irregular ventrianal shield with 4–5 setae (rarely an anal shield with 3 setae), a long and barbed seta j6, and a barbed macroseta on basitarsus IV. Phytoseiulus persimilis has an anal shield with only 3 setae, a long and barbed seta j6, and a barbed macroseta on basitarsus IV. Both P. macropilis and P. persimilis have vase-shaped spermathecae with distinct necks and basal swellings.

Ecology and distribution

Phytoseiulus fragariae is known only from Brazil in South America.
