Blamada rubripronota sp. nov.

( Figs 1–27 )

Description (based on ten males and eight females): Male: length: 9.7–12.5 mm, humeral width: 2.6–3.3 mm. Female: length: 11.6–13.1 mm, humeral width: 3.2–3.4 mm. Body black. Head black, with frons to occiput covered with dense orange red pubescence ( Figs 2 h, 3h, 5h, in some male cases whitish at base, Fig. 4 h); antennae black. Prothorax covered with dense orange-red pubescence except ventral part and narrow line at base ( Figs 1–6 ). Scutellum black. Elytra black, without any maculae, covered by rather dense, very fine, dark pubescence, and on basis or basal half with some longer erect hairs. Ventral surface black with grayish white pubescence. Legs black. Head not broader than prothorax. Eyes deeply emarginate, inferior eye lobe much higher than gena below it, width subequal to (male) or shorter than (female) ½ of frons. Antennae longer than body with 9th segment in male 10th segment in female extending beyond elytral tip, and basal six segments fringed with dense setae. Antennomere ratio: male, 16 5 24 16 15 13 13 12 12 11 14; female, 13 4 20 13 12 11 11 10 10 9 10. Prothorax broader than long. Elytra subparallel, rounded apically, densely punctured, each with a humeral longitudinal ridge not reaching the apex and with a dorsal carina on basal third. Hind femur reaching fourth abdominal segment, first hind tarsal segment slightly shorter than the following two segments combined. Male terminalia ( Figs 14–18, 20– 26 ): Tegmen about 2.0 mm in length; lateral lobes slender ( Figs 15, 22 c), each about 0.6 mm long and 0.1 mm wide, provided with finely haired ridge at ventral base ( Figs 15 a, 25), apex with long setae; ringed part elbowed in widest portion, converging; basal piece bifurcated apically ( Figs 15 c, 22c); median lobe plus median struts moderately curved ( Fig. 21 b), subequal to tegmen in length; median struts slightly more than one half of whole median lobe in length; dorsal plate slightly shorter than ventral plate; apex of ventral plate pointed ( Figs 17, 23 ); median foramen elongated; internal sac about 2.5 times of whole median lobe in length, with three pieces of basal armature ( Fig. 26 ) and three rods of endophallus ( Figs 16, 18, 24 ); two longer rods each about 1.1 mm, only about half length of tegmen, the shorter one about 0.9 mm and can be bifurcated ( Fig. 18 ). Tergite VIII ( Figs 14, 20 ) slightly broader than long, apex rounded with a small median groove, with dense and long setae. Sternite IX ( Figs 14, 20 ) Y-shaped, with middle part expanded. Female terminalia: Spermathecal capsule ( Figs 19, 27 ) consisting of a distinctly expanded apical lobe and a curved stalk; stalk slightly longer than apical lobe. Tignum shorter than abdomen. In our observation, tignum 4.2 mm for an adult with a 5.3 mm abdomen in ventral view.

Etymology. The species is named after the orange-red pubescent pronotum.

Remarks. This species resembles Paraglenea atropurpurea Gressitt at first glance by the similar shape and colour. The modified distal scape and longer pedicel and simple claws in both sexes exclude this species from the genus Paraglenea .

P. atropurpurea was described based on an unique female holotype ( Figs 29–30 ), which was deposited in Sun- Yatsen University. After studying a series of fresh specimens, we can confirm that the male claws are appendiculate, which makes it reasonable to place the species in the genus Paraglenea , although its elytral lateral carina is not as strong as that of typical Paraglenea . Further details will be shown in future revisional work on Paraglenea .

We consider the limited specimens from Vietnam and China to be the same species as the type locality fauna for this moment. Further study is needed when enough material is available because some small differences exist, such as: the unique male from Vietnam seems to have slightly longer antennae and sternite IX without expanded middle part; the unique female from China has a shorter basal curved stalk in spermathecal capsule than that from Laos. Without series of material, it is difficult to conclude whether this represents variation within species or differences between species.
