Stigmatolaelaps

 

HARMFUL | NOT HARMFUL | UNCERTAIN

possibly kleptoparasitic; suspected to feed on pollen and nectar in bee nests

Name and classification

Stigmatolaelaps Krantz, 1998

Taxonomy
Superorder Parasitiformes » Order Mesostigmata » Suborder Monogynaspida » Hyporder Dermanyssiae » Family Laelapidae » Genus Stigmatolaelaps

Type species
Hypoaspis greeni Oudemans, 1902, in part

Diagnosis

Female: Stigmatic fields enlarged: width of stigmatic field more than twice base of tritosternum (Figs. 2, 3, 6). Peritremes typical, extending anteriorly beyond legs II (Figs. 1, 3). Sternal setae st3 situated on sternal shield, not extending beyond bases of st4 (Figs. 4, 5). Unpaired setae on posterior opisthosoma present.

Species identification

A dichotomous key is available in Krantz, 1998a.

Similar genera

Pneumolaelaps and Xylocolaelaps. Stigmatolaelaps differs from both these genera by its enlarged stigmatic fields that are more than twice the base of tritosternum (Figs. 2, 3, 6)

Distribution

tropical Asia

Bee hosts

Large carpenter bees of the genus Xylocopa, subgenus Mesotrichia

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

permanent

Host associations, feeding, and dispersal

  • All stages live in nests of bees, where they probably feed on pollen as kleptoparasites.
  • Females disperse on adult bees.

Biology

Based on gnathosomal morphology, this genus probably feeds on pollen and adhering substances such as nectar in bee nests (Krantz, 1998a).

Phoretic female mites are usually located on the bee body. Occasionally they enter the metasomal acarinarium if it is not fully occupied by larger mites of the genus Dinogamasus (Krantz, 1998a).
