| Summary: | Two new bristletail species,
Trigoniophthalmus kobani sp. n. and T. tseyi sp. n., are
described from the North Ossetia – Alania. The new
species with 2 + 2 eversible vesicles on urites II–IV belongs
to a group of small species of the subgenus Trigoniocellus
Kaplin, 2010. Trigoniophthalmus kobani sp. n. differs
from other species of this group by the color of paired
ocelli, ratio of lengths of apical article and preceding one
of maxillary palp, posterior angle of urosternites II–V. The
main differences of T. tseyi sp. n. are the ratio of distance
between inner margins of paired ocelli to total width of
eyes, presence of spine-like setae on legs, small posterior
angle of urosternites II–V, large number of inner sublateral
spines on urocoxite IX |
