Species identification

This genus includes only a single species, Neohypoaspis ampliseta.

Similar genera

The presence of rounded ends in some marginal idiosomal setae and legs is similar to the genus Eumellitiphis. See the Diagnosis section to distinguish the genera Neohypoaspis and Eumellitiphis.

Distribution

Neotropical region

Bee hosts

necrophagous (corpse- or decaying flesh-feediing) species of the stingless bee Trigona (Meliponini), for example, Trigona hypogea and Trigona fulviventris

Host association level

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

Host associations, feeding, and dispersal

  • All stages live in nests of bees.
  • Dispersal on adult bees has not been documented, but is possible.

Biology

Neohypoaspis ampliseta is associated with nests of necrophagous species of the stingless bee genus Trigona (Meliponini) in the Neotropics. These mites have been found in the outer sheath of the nest, typically at the base of the nest, often in areas the bees do not reach because of the small passageways connecting them. Large populations of mites (in the thousands) develop in the nest. This species is probably beneficial as it feeds on various mites (and probably other microarthropods) in the nest. Under laboratory conditions, it consumes astigmatid mites (Delfinado-Baker et al., 1983Delfinado-Baker et al., 1983:
