Eight species of the genus Glenea Newman, 1842 from the Oriental Region, with description of three new species (Coleoptera: Cerambycidae: Lamiinae: Saperdini) Author Lin, Meiying Author Tavakilian, Gérard Author Montreuil, Olivier Author Yang, Xingke text Zootaxa 2009 2155 1 22 journal article 10.5281/zenodo.275010 f1787174-b824-4ce0-adc9-23d7507c49aa 1175-5326 275010 Glenea paradiana Lin et Montreuil sp. nov. ( Figs 1–5 ) Description. Male: length: 18.0– 21.2 mm , humeral width: 5.2–6.1 mm . Female: length: 20.8–26.0 mm, humeral width: 6.2–7.8 mm . Body dark violet to dark blue. Head violet black or dark blue, with four white pubescent maculae above, two stripes on occiput, one very small spot behind superior eyelobe. Male with eyes surrounded with white pubescence, genae densely clothed with white pubescence, frons sparsely covered with whitish pubescence; female with frons and genae seldom covered with white pubescence. Antenna black, with a faint grayish pubescence. Prothorax dark violet to blue, each side with a large snow-white patch adjacent to coxa; disc with a median white vitta interrupted in middle and broader posteriorly; each lateral margin with a white stripe usually interrupted in the middle. Scutellum white. Elytron dark violet or dark blue, with 2 pairs of round snow-white spots, the pair near suture much larger and closer to base than the one near margin; just before apex a transverse white fascia extending from margin to near suture. Ventral surfaces dark violet or dark blue; sides of meso- and meta-sterna spotted with white pubescence, and each of the first four abdominal segments with a single large white spot on each side. Femora reddish brown and glossy; tibiae and tarsi of fore and mid legs grayish black, hind tibiae and tarsi fulvous-brown. Head as broad as prothorax. Eyes medially emarginate, inferior eyelobes 4 times (male) or about twice (female) as high as genae below. Antennae relative slender, longer (male) or shorter (female) than body; antennomere ratio: male: 23 5 35 25 28 27 25 24 23 22 24; female: 23 5 34 23 26 22 21 19 18 16 15. Prothorax densely punctured, with 2 calluses and a carina on basal half of middle line. Elytron densely and coarsely punctured, gradually narrower apically, with 2 lateral carinae, reaching apex; apex transversely truncated, with a very minute and scarcely perceptible tooth at each angle. Legs stout, middle tibiae grooved, hind femur reaching apex of fourth abdominal segment, first hind tarsal segment distinctly longer than following two segments combined. Male claws: anterior claws of fore and mid tarsi furnished at base, a little towards outer side, with a distinct tooth; all other claws (the anterior claw of hind tarsi and posterior claws of all tarsi) simple. Female claws all simple. Male genitalia ( Figs 3 a–c): Tegmen length about 5.8 mm ; lateral lobes stout, each about 1.5 mm long and 0.5 mm wide, with a curved ridge bearing fine hair at base; apex with setae shorter than half of lateral lobes; lateral lobes with ventral grooves filled with very short setae; no well-developed basal piece; median lobe plus median struts moderately curved, slightly longer than tegmen (31:29); median struts less than 1/4 of whole median lobe in length; dorsal plate shorter than ventral plate; apex of ventral plate projected, with two small lobes before apex; median foramen elongated, round at apex; internal sac more than twice as long as median lobe plus median struts, with 4 pieces of basal armature (1 median pair, 1 bigger and 1 smaller), 2 different sized bands of supporting armature, and 3 rods (2 longer and 1 shorter); longer rods each about 2.5 mm , shorter than half of tegmen. Tergite VIII ( Fig. 4 ) as broad as long, apex broadly projected, with moderate long setae at sides, shorter and sparser setae on projected lobe in the middle. Ventrite IX subequal to ringed part of tegmen in length. Female terminalia ( Fig. 5 ): Spermathecal capsule consisting of an apical elliptical lobe and a stalk, stalk strongly curved and somewhat coiled, slightly longer than apical lobe. Tignum slightly longer than abdomen. FIGURES 1–2.

Scale 1 mm. Diagnosis. Differs from G. diana Thomson in having very different male genitalia and different maculae on prothorax and elytron. More detail see “Remarks” below. Etymology. Because it is similar to G. diana . Remarks. While studying G. diana Thomson ( Fig. 6 ), we found this new species unexpectedly. The new species can be easily distinguished from G.. diana by: 1. female antenna shorter than body; 2. white pubescence spot behind superior eyelobe very small or vague; 3. white spots on elytron with different sizes and distances; 4. hind tibiae totally fulvous-brown; 5. male genitalia with lateral lobes stout, median struts shorter than 1/4 of median lobes with median struts, longer robs shorter than half of tegmen; 6. female genitalia with the expanded apex of spermathecal capsule.
