Original description: Tachycines
boldyrevi Uvarov 1926
Ann. Mag. Nat. Hist. (9)17: 284.
♀. A very uniformly coloured species
with the hind femora only very feebly spined below, which makes
it intermediate in this respect between the subgenera Tachycines,
s. str., and Gymneta,
Ad. Fastigium of vertex quite depressed, angulately
incised. Pronotum distinctly convex in profile, narrowed in front;
front margin convex; hind margin very slightly convex. Lateral lobes
of mesonotum depressed, broadly rounded-truncate behind. Front coxae
with a short, but acute, conical tooth; front femora with a short,
mobile, external apical spine; front tibiae with two pairs of spines
on the lower margin, and with three apical spurs and a short median
spinule. Middle coxae unarmed; middle femora with two apical mobile
spines, the hind one being longer; middle tibiae with four spines
below, four spurs, and a median apical spinule. Hind femora with
four minute spinules below, without the genicular spine; hind tibiae
with about 85 densely-placed spines, very indistinct1y separated
into small series of two to three spines each, the 60th (approximately)
spine, counting from the base, is much larger than others; apex
of tibiae with two spinules above, two slightly longer ones below,
one short outer spur, and two inner spurs, the upper one of which
is slightly shorter than metatarsus. Last abdominal tergite trapezoidal,
with the sides incurved and the apex truncate. Supra-anal plate
slightly longer than broad, slightly narrowed to the elliptical
apex. Subgenital plate longer than broad, narrowly parabolic, feebly
convex. Ovipositor with both upper and lower margin slightly curved;
apex distinctly recurved; upper valvae strongly narrowed apical1y,
but with the immediate apices blunt; lower valvae with the apices
moderately narrow, but acute, with about eight scarcely perceptible
subapical incisions below. Coloration uniform1y dull
brown, legs paler, without any markings, tarsi and palpi whitish. Length
of body 15; pronotum 5.5; front femur 10; front tibia 10.5; middle
femur 10; middle tibia 9; hind femur 18; hind tibia 19; ovipositor
13 ㎜. Described from one adult female and two female
larvae. I named this species after my friend Professor
V. F. Boldyrev, whose brilliant works on bionomics of Orthoptera
are well known and remarkable for the rare combination of scientific
accuracy and thoroughness with a vivid, sometimes almost poetical,
narrative. T. boldyrevi
differs from all known species already by its very uniform coloration,
reminding one of Dolichopoda. It resembles in this respect
T. racovitzai
Chop., from caves near Tonkin, but that latter species differs from
it by the female subgenital plate dentate basally, by the hind legs
being longer, and by some details in the armature of legs. In
the armature of hind femora T. boldyrevi
presents a connecting-link between Tachycines
Ad., and Gymneta
Ad., because the femoral spinules in my species are smaller and
less in number than in Tachycines,
but still not absent altogether as it should be in Gymneta;
this confirms Chopard's conclusion (Bull. Soc. Ent. France, 1916,
p. 158) that the degree of development of the spinules cannot be
regarded as more than a subgeneric character.
