Etymology. Dedicated to Dr. Akiko Saito of the Natural History Museum and Institute,
Chiba, who collected the holotype.
Diagnosis. Stenandra saitoae sp. n. (Fig. 9) differs from S. vadoni Quentin & Villiers,
1972 (Fig. 4), mainly by anterior upper eye edge (Fig. 9) placed close to base of
antennae (distant from base of antennae in S. vadoni – Fig. 1). From S. kolbei (Lameere,
1903) (Fig. 6) it differs by the carina of ventral sensorial area of antennomeres
III-XI distinctly visible in lateral view (Fig. 11), dorsal sensorial area of antennomere
XI small (Fig. 10), antennomeres enlarged towards inferior edge (Fig. 10), and suture
of the elytra apically divergent. In S. kolbei, the carina of ventral sensorial area of antennomeres
III-XI is not or very slightly visible in lateral view (Fig. 7), the dorsal sensorial
area of antennomere XI is large (Fig. 3), antennomeres not distinctly enlarged towards
inferior edge (Fig. 3), and the elytral suture is not divergent at the apex. From S. asiatica
sp. n. it differs mainly by the small sensorial area of antennomere XI (Fig. 10), the
more sparse elytral punctation, and by the elytral suture divergent apically.
Female: Integument dark-brown; parts of the mandibles, margins of the pronotum,
elytral suture, pro- and mesosternal process, trochanters, extreme ventral apex of
tibiae blackish; elytra laterally and apically darker than the remaining surface.
Dorsal area of head coarsely punctate; punctures sparser at central area, coarser,
more abundant and confluent at side; punctures between upper eye lobes with short,
apically spatulate setae; punctures between posterior eye margin and margin of pronotum
with very short, thick setae. Area behind eyes coarsely, confluently punctate
near apices of upper eye lobes, sparsely near lower eye lobes; nearly all punctures with
single, very small, thick seta. Clypeus coarsely, densely punctate, except at smooth
central area; punctures with short, spatulate setae. Labrum smooth, glabrous laterally;
coarsely punctuate; with short, spatulate setae around central projection. Upper
eye lobe not notably separated from base of antenna. Submentum coarse; densely
punctate near anterior margin (confluently centrally), sparsely and coarsely near gena;
each puncture with a small, spatulated seta; anterior edge slightly elevated throughout.
Mentum with dense, spatulate setae, somewhat longer laterally. Mandibles punctate;
external punctures coarse, deep, dense and accompanied with spatulate setae; internal
punctures sparse. Carina of ventral sensorial area of antennomeres elevated and visible
in lateral view (Fig. 11), mainly after antennomere VIII; dorsal sensorial area of the
antennomere XI (Fig. 10) elliptic, small, not reaching apex of antennomere; antennomere
XI distinctly and abruptly sloped dorsally just after middle; antennomeres distinctly
enlarged towards inferior edge (Fig. 10), more distinctly after antennomere IV. Pronotum finely, sparsely punctate; punctures gradually becoming coarser and
more abundant near lateral margin; lateral punctures with very small, spatulate seta.
Prosternum coarsely, moderately densely punctate; nearly all punctures with small,
spatulate seta. Prosternal process sparsely punctate (punctures with same type setae as
prosternum). Mesosternum strongly, densely, deeply, confluently punctate, with a few
very small, spatulated setae. Mesosternal process subglabrous and smooth. Mesepisterna
coarsely, moderately densely punctate. Metasternum finely and sparsely punctate
centrally; punctures gradually becoming coarser and denser towards lateral area; punctures
close to metacoxae with small, spatulate setae. Elytra coarse; punctures dense on
lateral parts and apical one-fourth; lateral punctures with very small thick setae, more
conspicuously towards apices; punctures of apical one-third with small, spatulate setae;
suture divergent at apex.
Urosternites densely punctate, mainly laterally; setae short, dense and spatulate,
thick laterally; urosternite V with somewhat long, dense setae at margin, more conspicuous
centrally (each seta apically spatulate). Coxae moderately sparsely punctate. Tibiae somewhat flat dorsally and sulcated laterally. Metatarsomere V (excluding claws)
longer than I-III together.
Dimensions in mm (♀). Total length (including mandibles), 13.4; prothorax: length,
2.5; anterior width, 2.9; posterior width, 2.7; humeral width, 3.4; elytral length, 7.9.
