J. Tormos et al., DESCRIPTION OF MATURE LARVAE OF MICRODYNERUS-EXILIS AND MICRODYNERUS-TIMIDUS (HYMENOPTERA, VESPIDAE), Entomological news, 108(4), 1997, pp. 259-264
The mature larvae (prepupae) of Microdynerus exilis and M. timidus are
described. The number and arrangement of the sensilla and setae on th
e labrum and the sensilla on the epipharynx are the characters which b
est provide differentiation of these species from the other previously
described from this genus: M. nugdunensis.
