Supplementary description. Male: length: 6.5–7.7 mm, humeral width: 1.9–2.3 mm. Female: length: 7.8–9.6 mm, humeral width: 2.3–2.9 mm. Antennomere ratio: male, 10 2 13 11 9 8 8 8 8 8 9; female, 12 2 16 12 10 9 9 8 8 7 9. Male terminalia ( Figs 12–13 ): Tegmen about 1.6 mm in length; lateral lobes stout, each about 0.4 mm long and 0.15 mm wide, with finely haired ridge at ventral base, apex with setae nearly as long as lateral lobes; basal piece not bifurcated distally; median lobe plus median struts moderately curved, a little longer than tegmen; median struts subequal to one half of whole median lobe; dorsal plate shorter than ventral plate; apex of ventral plate slightly pointed; median foramen widely elongated, rounded at apex; internal sac more than 3 times of median lobe plus median struts, with five pieces of basal armature, two bands of supporting armature and three rods; rods about 2.3 mm, much longer than tegmen. Tergite VIII transverse, apex slightly pointed in middle, with moderate dense and long setae. Ventrite IX subequal to ringed part of tegmen in length. Female terminalia ( Figs 14–15 ): Spermathecal capsule consisting of an apical lobe and a stalk; stalk curved almost 180 degrees, nearly 1.5 times as long as apical lobe. Tignum nearly as long as abdomen.

Remarks. Gahan (1897) proposed Glenea fuscovirgata Fairmaire, 1883 as a synonym of Glenea glechoma Pascoe. Kano (1929) , Masushita (1933) and Gressitt (1951) didn’t mention this synonymy when they studied G. glechoma but Aurivillius (1926) and Breuning (1956) accepted Gahan’s opinion, removing the question mark. According to our study on type specimens as well as a series of specimens from type localities, the types of G. glechoma ( Fig. 6 ) and G. guadalcanalana ( Fig. 9 ) differ from others by having less pubescence, and their prothorax and elytra with lighter tegument. We also noticed some specimens with prothorax darker while elytra showing lighter brown ( Fig. 8 ). Most specimens have prothorax and elytra both black with quite dense pubescence stripes. Therefore, we consider the thinner pubescence and the lighter tegument as varieties within the species. We agree with Gahan (1897) about the conspecific relationship, and propose three new synonyms: G. palawana Breuning, 1956 , G. guadalcanalana Breuning, 1958 and G. hamabovola Hayashi 1975 .
