Stevelus

 

HARMFUL | NOT HARMFUL | UNCERTAIN

presumably lives in bee nests and disperses on adult bees; details of biology unknown

Name and classification

Stevelus Hunter, 1963

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

Type species
Stevelus amiculus Hunter, 1963

Diagnosis

Female: Idiosomal shield short, not covering posterior body (Fig. 1). Peritremes wide, wider than stigma (Figs. 1, 5). Ambulacra elongated (Fig. 2, 11). Claws reduced (Fig. 11). Corniculi membranous (Fig. 6). Ventral gnathosomal setae (hypostomatic and palpcoxal) short, spiniform (Fig. 6).

Other diagnostic characters

Female: Peritremes not extending beyond legs II (Figs. 1, 5). Tectum well-sclerotized (Figs. 1, 9). Anal shield transversely oval (nearly circular); not elongated longitudinally or triangular (Fig. 10).

Species identification

This genus is known from a single species, Stevelus amiculus.

Distribution

Neotropical region (Panama)

Bee hosts

The single known female was collected from the nest of an unidentified stingless bee (Meliponini) (Hunter, 1963).

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 (assumed)

Host associations, feeding, and dispersal

  • All stages presumably live in nests of bees.
  • Females presumably disperse on adult bees.
