Etymology.
The name is derived from generic names
Dolichostigma
Rasnitsyn, 1968
and
Syntexis
. Gender masculine.
Type
species.
D. transbaikalicus
sp. nov.
Species included.
Type
species only.
Distribution.
Lower Cretaceous of Transbaikalia.
Diagnosis.
Fore wing with costal area narrow; pterostigma very long and broad, reaching the middle of 3r cell; both 1r-rs and 2r-rs present, 1r-rs slightly longer than 2r-rs; cell 2r small, as wide as pterostigma; cell 3r very long; Rs+M furcating before 1m-cu, 2Rs+M absent, cell 1mcu hexagonal.
Comparison.
Dolichosyntexis
differs from all other syntexines in having very long and broad pterostigma reaching the middle 3r cell, and small 2r cell. It also differs from
Eosyntexis
and
Cretosyntexis
in presence of two r-rs veins; from
Syntexis
and
Parasyntexis
in Rs+M furcation before 1m-cu.
Remarks.
By the huge pterostigma
Dolichosyntexis
is close to another anaxyelid subfamily—Dolichostigma-tinae. But it differs in having long Rs+M and cell 2r very short. Basing on these characters I assign the new genus to
Syntexinae
and not to
Dolichostigmatinae
.
