ABSTRACT. Basing on the study of the collections stored
in Zoological Institutute, St.-Petersburg and Moscow Pedagogical State
University the larvae of Scarites angustus (Chaudoir,1855) and Scarites
laevigatus Fabricius, 1775 were originally described, but the larvae of
Scarites planus Bonelli, 1813, Scarites terricola Bonelli, 1813, Scarites
eurytus Fischer von Waldheim, 1825 and Scarites bucida (Pallas,1778) were
redescribed using the data on the chaetotaxy. On the basis of these data and
taking in to consideration some imaginal features the new subgenus
Paradistichus
Makarov, subgen.n. [the type species - Scarites angustus (Chaudoir, 1855)]
is established. It is characterized by the specific combination of some
imaginal features (pronotum with 2 pairs of lateral setae, metasternum
with 3 - 5 pairs of setae, metacoxa with 3 setae, abdominal sternites without
transversal furrows, mesotibia with one large spur) and several larval traits
(nasale narrow protruding, the setae FR10 and FR11 drawn together, supraocellar
furrow turns on ventral surface into the long oblique carina, third antennal
joint with large flat sensorium, apical spurs on femora and tibia of
common shape,
short setae UN1 and UN2 situated in basal third of claws, claws very long).
Diagnoses of the tribe, genera and subgenera based on larval characters as
well as the keys for subgenera of Scaritini larvae of Russia and adjacent
lands are given.
