Afrocypholaelaps

Taxonomic Position

Cohort Gamasina

    Subcohort Dermanyssiae

  Superfamily Ascoidea

Family: Ameroseiidae Berlese
Afrocypholaelaps Elsen

 

Diagnostic characters:

 

Similar taxa. The most reliable character for the Ameroseiidae is the lack of setae J5 on the posterior dorsal shield. However, among the taxa with toothed or bifurcate corniculi, ameroseiids are likely to be commonly confused only with species of Proctolaelaps, which occur in similar habitats, but Proctolaelaps have numerous dorsal shield setae (including most of the r-R rows) and a ventral mucro on the chelicerae; rami of spermatheca fused.    Species of Hattena and Neocypholaelaps also live in flowers, eat pollen and nectar, and use birds or insects for transport and can be differentiated in the key below.

Key to Flower-inhabiting Ameroseiidae (females)

1.  Dorsal setae in s- & r-series setae leaf-like and biserrate...Neocypholaelaps stridulans group

-    Dorsal setae acicular, simple or weakly barbed..................................................................2

2.  Pretarsi with distinct claws; often some dorsal shield setae thickened & barbed...Neocypholaelaps

-    Pretarsi without distinct claws, only pad-like pulvillus; dorsal shield setae fine, simple.......3

3.  Dorsal shield with 29 pairs of setae; ducts fused above spermatheca...............................Afrocypholaelaps

-    Dorsal shield with 25 or fewer pairs of setae; ducts separate............................................Hattena

Ecology & Distribution.  Species of Afrocypholaelaps inhabit flowers and feed on pollen and nectar.  They are phoretic on flower-visiting insects, including honeybees and lepidopterans.  A. africana is known from Africa, Australia and Papua New Guinea; A. lindquisti (Prasad) from a noctuid moth in Hawaii;  A. ranomafanaensis Haitlinger from a butterfly in Madagascar.
