Diagnosis

Female: Dorsal shield not rugose, without large ridges (Figs. 1, 3; compare with Ameroseius where it is rugose), with less than 25 pairs of setae (Figs. 1, 3). Setae j1 simple, filiform, setae J5 absent (Fig. 3). Corniculi undivided (or divided), surrounded by transparent membrane (Fig. 8). All legs with well developed ambulacrum, claws reduced (Fig. 12). Spermathecal ducts (rami) not fused (Fig. 15).

Species identification

A dichotomous key is available in Faraji and Cornejo, 2006, but Hattena dalyi (Elsen, 1974) comb. nov. (from Afrocypholaelaps) is omitted.

Distribution

Known from the tropics of the Old and New Worlds (Ecuador, Kenya, Taiwan, Australia, and south-east Asia). Has been found on bees only in the Old World.

Bee hosts

Bee records include the European honey bee Apis mellifera, an unidentified bee, and the small carpenter bee Ceratina subquadrata.

Host association level

Permanent

associated exclusively with bees or their close relative, wasps; cannot live without these hosts

Temporary

some life stages are associated with bees, while others are not

Facultative or opportunistic

can complete entire life cycle without bees or their close relative, wasps

facultative

Host associations, feeding, and dispersal

  • All stages normally live on flowers of various tropical plants and feed on their pollen and nectar.
  • Dispersal occurs on adult bees and other flower-visiting animals. Female is the phoretic stage.

Biology

Three species are known from bees: Hattena dalyi (Elsen, 1974), Hattena ewae (Haitlinger, 1987), and Hattena tonganus (Manson, 1974). Although there is no host specificity to a particular animal carrier, some host plant specificity may exist. For example, in Australia, Hattena incisa occurs only in the flowers of the stilted mangrove, Rhizophora stylosa, while Hattena panopla occurs in the flowers of a range of plants, but not those of R. stylosa (Halliday, 1997).
