Abstract
The morphology of first instar larvae of three species of Miltogramma Meigen subgenus Pediasiomyia Rohdendorf is
described using SEM and light microscope techniques. Miltogramma chrysochlamys (Rohdendorf), Miltogramma
margiana (Rohdendorf) and Miltogramma przhevalskyi (Rohdendorf) share with other satellite flies the presence of an
elongated sensillum basiconicum of the maxillary palpus and numerous longitudinal cuticular ridges on the integument
of all segments; and they share with other Miltogramma spp. a maxillary palpus situated on a more or less raised base.
While the first instar M. margiana is very similar to first instars of Miltogramma (sensu stricto), first instars of
M. chrysochlamys and M. przhevalskyi share several features unique among Miltogramminae: antennal dome situated
on a flat or indistinct basal ring, antennal dome flattened, border between pseudocephalon and first thoracic segment
with a pair of fleshy processes, and basal ring with trichoid sensillum. First instars of M. chrysochlamys and
M. przhevalskyi are unique in having both sb1 and sb2 of the sensilla basiconica of the maxillary palpus elongated, and
M. przhevalskyi has an unpaired, median proleg on most abdominal segments.
