Glenea diana Thomson, 1865: 561 (Assam) .

Glenea bimaculiceps Gahan, 1889: 215 ( Myanmar) . Glenea theresae Pic, 1943: 15 ( Cochinchina) . syn. nov. Glenea (Glenea) diana ssp. theresae: Breuning, 1956: 135 .

Supplementary description. Male: length: 15.7–20.0 mm, humeral width: 4.3–5.4 mm. Female: length: 17.5–25.5 mm, humeral width: 5.0– 7.7 mm. Head as broad as prothorax. Eyes medially emarginate, inferior eyelobes 5 times (male) or about twice (female) as high as genae below. Antennae relative slender, longer than (male) or subequal to (female) body; antennomere ratio: male: 17 3 27 20 24 23 22 21 20 18 21; female: 20 3 30 20 24 23 22 19 18 17 19. Elytron densely and coarsely punctured, with outer two lines well arranged, gradually narrower apically, with 2 lateral carinae, reaching apex of elytron, transversely truncated apically, with a very minute and scarcely perceptible tooth at each angle. Legs stout, 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 simple. Male genitalia ( Figs 9 a–c): Tegmen length about 3.8 mm; lateral lobes somewhat stout, each about 1.0 mm long and 0.3 mm wide, with a ridge bearing fine hair at base, apex with setae shorter than half of lateral lobes; no basal piece; median lobe plus median struts moderately curved, longer than tegmen (45:38); median struts more than 1/3 of whole median lobe in length; dorsal plate shorter than ventral plate; apex of ventral plate projected; median foramen slightly elongated; internal sac more than twice as long as median lobe plus median struts, with 4 pieces of basal armature and 3 rods (2 longer and 1 shorter); longer rods about 2.8 mm, longer than half of tegmen. Tergite VIII ( Fig. 10 ) 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. 11 ): Spermathecal capsule composed of an apical elliptical lobe and a stalk; stalk strongly curved, about twice as long as apical lobe. Tignum subequal to abdomen.

Diagnosis. Differs from G. lepida in having two round white spots behind superior eyelobe.

Remarks. Glenea theresae Pic, 1943 ( Fig. 8 ) was considered as subspecies of G. d i a n a by Breuning (1956). After examination of a series of specimens from MNHN, MHNL and NHML, we recognized that the difference described by Breuning was in fact the sexual dimorphism and G. theresae appeared to be the male of G. d i a n a. Therefore, G. t h e re s a e Pic, 1943 should be considered as a junior synonym of G. diana Thomson, 1865 .

In the study of Glenea (Glenea) diana ssp. niasana Breuning, 1969, we found that it was very different from G. diana and obviously not a subspecies of G. diana . It seems closer to G. c y b e l e Thomson, 1865 (so far considered a morph of voluptuosa Thomson, 1860). However, without more specimens available, we can not make any conclusion.
