urn:lsid:zoobank.org:act: ED78F0DE-63CF-4674-8CD6-39523A44E2CC
Figs 1 E–F; 2B, F
DiagnosisThis species is morphologically similar to Brachypsectra kadleci (Fig. 1 A–F), but differs in having smaller eyes (minimum interocular distance 1.40–1.45 times maximum eye diameter in B. jaechi sp. nov., 0.95–1.05 times in B. kadleci), pronotal lateral sides more strongly diverging posteriorly, with posterior angles more distinctly produced laterally and posterior carina far from lateral carina, closer to posterior margin (Fig. 2 A–B), width between posterior angles 1.9 times width between anterior angles (1.5–1.7 times in B. kadleci), scutellum more broadly rounded posteriorly (narrowly rounded in B. kadleci), phallobase more deeply emarginated basally, gradually diverging apically (more angulate, almost subparallel-sided apically in B. kadleci), and parameres wider, distinctly constricted subapically, with subapical lateral projection subacute (slightly constricted subapically, with subapical lateral projection rounded in B. kadleci; Fig. 2 D–F).
EtymologyThe specific epithet is a patronym in honor of Manfred A. Jäch (NHMW).
Type materialHolotype
TURKEY: ♂, Kemer, Antalya Prov., 3–15 Jul. 1989, H. Schmid leg. (NHMW).
Paratype
TURKEY: ♂, same data as for holotype (NHMW).
Type localityTurkey, Antalya Prov., Kemer.
DescriptionMale (holotype)
BODY. 5.6 mm long, 2.3 times as long as wide, elongate oblong, dorsoventrally flattened. Body surface testaceous to reddish brown, ventral parts of thorax darker, elytra dark brown, legs yellowish-testaceous; body covered with yellow pubescence (Fig. 1E).
HEAD. Including eyes 0.5 times as wide as pronotum; eyes medium-sized, protuberant; minimum interocular distance 1.45 times maximum eye diameter; frons depressed medially; head covered with shallow, irregularly distributed punctures and short, semi-erect to erect pubescence. Antenna 11-segmented; scape elongate; pedicel short, subquadrate; antennomere 3 elongate, about two times longer than wide; antennomeres 4 and 5 simple, subequal, slightly longer than wide; antennomeres 6–10 expanded on one side to form (with apical antennomere) a pectinate club; apical antennomere expanded, with additional trapezoidal broadening apically (Fig. 1E).
PRONOTUM. Transverse, 1.9 times as wide as long, subtrapezoidal, widest posteriorly, width between posterior angles 1.9 times width between anterior angles; anterior margin almost straight; lateral sides convex, strongly converging anteriorly and diverging posteriorly, with distinct lateral carina concealed anteriorly in dorsal view; posterior margin trisinuate. Anterior angles obtuse, posterior angles produced posterolaterally, apically truncated, with short, distinct posterior carina, well separated from lateral carina in dorsal view (Fig. 2B). Disc convex, with very shallow longitudinal medial furrow, covered with sparse subcircular punctures and short, semi-erect pubescence. Prosternum slightly convex, including prosternal process 1.2 times as long as wide, sparsely covered with coarse punctures; chinpiece very short; prosternal process subparallel-sided, curved, slightly converging apically, with apex broadly rounded. Scutellum subtrapezoidal, slightly wider than long, lateral edges slightly rounded, apex broadly rounded. Metaventrite finely and sparsely punctate. Elytra subparallel-sided, slightly widened at posterior third, about ¾ of body length, 1.7 times as long as combined width, 4.0 times as long as pronotum, with distinct humeral bulge and widened lateral margins; disc dorsoventrally flattened, very weakly striate, covered with fine punctures and short, semi-erect pubescence. Legs moderately long, slender, slightly compressed; tarsomeres 1–4 gradually shortened, tarsomere 4 minute, apical tarsomere narrow, longest; claws simple.
ABDOMINAL VENTRITES. Flattened, finely and moderately densely punctate; ventrites 1–4 subequal in length, ventrite 5 broadly rounded posteriorly. Aedeagus trilobate; median lobe longer than paramera, gradually narrowed towards apex, slightly constricted subapically, rounded apically, with moderately long basal struts, u-shaped, slightly converging anteriorly. Parameres robust, longer than phallobase, moderately wide, distinctly constricted subapically, with distinct subapical subacute lateral projection and projected rounded apex. Phallobase short, wider than long, narrowed and moderately deeply emarginated basally, gradually diverging apically (Fig. 2F).
Female and immature stages
Unknown.
Intraspecific variability
The second known male specimen (Fig. 1F) is 5.0 mm long, with the body 2.4 times as long as wide, pronotum 2.0 times as wide as long, and the minimum distance between eyes 1.40 times longer than the eye diameter.
DistributionThis species is known only from Kemer in Antalya Province, southern Turkey (Fig. 3).
