( Figs. 12–17 )

Glenea subsimilis Gahan, 1897: 479 ( India) .

Glenea rubripes Pic, 1926: 19 ( Laos) .

Glenea (Glenea) subsimilis m. rubripes: Breuning, 1956: 136 .

Supplementary description. Male: length: 15.0– 15.7 mm, humeral width: 4.1–4.5 mm. Female: length: 18.5–26.0 mm, humeral width: 5.0– 7.8 mm. Scape and second antennomere black, antennomeres 3–11 red brown. Elytron with 7 whitish maculae: a small spot on basal centre; second to fourth located in basal half; fourth spot just behind third one and closer to lateral carina; fifth spot biggest, behind the middle and near suture; sixth dot very small, near lateral carina; the last one just before apex, transverse. Head as broad as prothorax. Eyes medially emarginate, inferior eyelobes 4 times higher than (male) or subequal to (female) genae below. Antennae slender, longer (male) or slightly shorter (female) than body; antennomere ratio: male: 15 3 29 19 21 20 20 20 18 17 18; female: 17 3 29 20 22 19 18 17 16 15 14. Hind femur reaching middle of last abdominal segment, first hind tarsal segment longer than following two segments combined. Male claws: anterior claws of fore and mid tarsi appendiculate, others simple. Male terminalia: ( Figs 15 a–c): Tegmen length about 3.3 mm; lateral lobes somewhat stout, narrower towards apex, each about 0.7 mm long and 0.2 mm wide, with a ridge bearing fine hair at base, apex with setae shorter than half of lateral lobes; basal piece reduced to membrane; median lobe plus median struts moderately curved, longer than tegmen (38:33); median struts about 1/3 of whole median lobe in length; dorsal plate shorter than ventral plate; apex of ventral plate arrow-headed; median foramen slightly elongated; internal sac about 3 times as long as median lobe plus median struts, with 4 pieces of basal armature and 3 rods (2 longer and 1 shorter); longer rods each about 1.8 mm, longer than half of tegmen. Tergite VIII ( Fig. 16 ) broader than long, apex projected, with moderate long setae at sides, shorter setae on projected lobe in the middle. Ventrite IX shorter than ringed part of tegmen. Female terminalia ( Fig. 17 ): Spermathecal capsule composed of an apical orb and a stalk; stalk very long and strongly curved, more than 3 times as long as apical lobe. Tignum shorter than abdomen.

Diagnosis. Differs from G. rufipes in having antennomeres 3–11 reddish brown, in having elytral apical teeth more obvious, and elytron having more small spots, with distance between first and second spots subequal to that between second and third, and fifth spot closer to third than to apical vitta.

Remarks. Gahan (1897) described the female while Pic (1926) described the male.

Although this name was recorded from China (Fujian, Guangdong, Hunan) ( Hua, 2002), it was based on misidentification of G. r u f i p e s Gressitt. The true G. subsimilis is newly recorded here from Yunnan.

Distribution. China (new record): Yunnan; Vietnam, Laos, India.
