Bioramix (Cardiobioramix) globipunctata sp. nov.

( Figs 1‒11 , 21‒22 , 25‒27 )

Diagnosis. The new species is similar to B. (C.) championi ( Reitter, 1891) but can be distinguished by the following urn:lsid:zoobank.org:pub:D207774F-0039-4932-9DEE-3C6F58D60EA1 Received 9 October 2015, accepted 1 April 2016

186 characteristics: pronotum and elytra densely covered with long golden setae, whereas setae are dust-like in the latter species; pronotum widest in the middle, anterior angles acute, and posterior angles rectangular, whereas pronotum widest in the middle or before the middle in the latter species, anterior angles acute, and posterior angles sharp or acute; strial punctures on elytra incomplete, whereas complete in the latter; the groove of the paramere from apical to base by the dorsal view weakly highlighted by the ventral view, whereas the groove of the latter extends only to 1/3 of the base, distinctly highlighted by the ventral view.

Description. Length 10.9–12.2 mm, width 3.7–5.7 mm. Body brown with weak bronze shine; head and pronotum black-brown, legs, antennae, labial and maxillary palpi and abdomen sepia; elytra with strong bronze shine.

Male ( Figs 1–11 , 21 ). Anterior margin of clypeus straight, clypeofrontal suture slightly concave, densely covered with fine punctures. Frons weakly convex, sparsely covered with fine punctures. Genae slightly and arcuately convex and densely covered with large punctures. Clypeus, frons, genae and vertex densely covered with recumbent long golden setae. Eyes transverse. Antennae ( Fig. 2 ) exceeding the base of pronotum, antennomeres II‒X long cylindrical and slightly expanded apically, XI pear-shaped, ratio of length (width) of antennomeres II‒XI as follows: 20.2 (13.9), 15.9 (15.4), 31.9 (16.0), 33.0 (13.9), 33.2 (14.5), 35.1 (15.0), 35.8 (13.8), 32.4 (15.7), 31.3 (13.9), 39.0 (13.9).

Pronotum ( Fig. 1 ) sub-rectangular, 1.5 times as wide as long, widest in the middle, and 1.7 times as wide as the head; densely covered with long golden setae. Ratio of pronotal width on anterior margin to the maximum width and to the width at posterior margin as 1.7: 2.7: 2.6; lateral sides have shallow depression before posterior angles, and distinctly constricted anteriorly at apical 1/2. Anterior margin distinctly concave, posterior margin almost straight. Anterior angles acute and posterior angles rectangular. Anterior and posterior margins bordered on both sides, lateral margins bordered along the whole length; disc punctures large and dense.

Elytra oblong, strongly convex, 1.4 times as long as wide, and 1.4 times as wide as pronotum; widest in the middle; disc fine wrinkles, punctures large and dense; lateral carina visible in dorsal view only anteriorly, combined with epipleura and reaching the sutural angle; humeri rounded, densely covered with long golden setae.

Propleura covered with longitudinal wrinkles and recumbent golden setae. Prosternal process slightly curved downwards in ventral view, slightly sharp and rectangular at apex. Pro- and mesosterna covered with recumbent golden setae.

Profemur strong, sparsely covered with punctures and recumbent golden setae. Protibia gradually widened apically; inner side slightly curved, densely covered with recumbent short golden setae at apical 1/2; apex of ventral side without depression; outer side not blade-shaped. Protarsus distinctly widened apically, wider than the apex of protibia. Meso- and metafemora slender. Mesotibia gradually widened apically, densely covered with recumbent golden setae. Mesotarsus slightly widened apically, narrower than the apex of mesotibiae. Metatarsus almost straight, densely covered with recumbent golden setae. Ratio of length (width) of pro-, meso- and metafemora is 2.2 (0.7): 2.2 (0.5): 2.7 (0.5), that of tibiae ( Figs 3–5 ) is 1.7 (0.3): 1.8 (0.3): 2.7 (0.4), that of tarsi ( Figs 6–8 ) is 1.4 (0.5): 1.6 (0.4): 2.0 (0.2); ratio of width (length) of pro-, meso- and metatarsomeres I–IV, respectively, as follows: 24.0 (13.9): 45.6 (37.8): 38.5 (27.5): 27.6 (21.9); 29.9 (18.7): 36.2 (34.1): 30.2 (28.4): 21.6 (18.3); 21.4 (73.2): 19.6 (40.3): 17.1 (29.5): 55.0 (16.0).

Abdomen sparsely covered with recumbent golden setae, anterior margin of visible sternum I wide and round, apical margin of visible sternum V wide and round, center of I‒II flattened.

Aedeagus ( Figs 9–11 ) length 1.6 mm, width 0.5 mm. Parameres widest at base, constricted nearly straight at anteriad, round and straight at apex.

Female ( Fig. 22 ). Body wider than male. Antennae shorter, reaching posterior to pronotum. Pronotum more transverse than male, approximately 1.6 times wider than long. Pro- and mesotarsi simple.

Body length 13.2 mm, width 6.6 mm.

Type material. Holotype ♂ ( MHBU), China, Ningxia, Jingyuan, Qiuqianjia, 7.VII.2009, leg. Xiaoqing Liu. Paratypes. 1♀ ( MHBU), same data as holotype; 1♀ ( MHBU), China, Ningxia, Jingyuan, Erlonghe, 23.VI.2008, leg. Hongfan Ran; 1♂ ( MHBU), China, Ningxia, Jingyuan, Dongshanpo, 18.VII.2014, leg. Ling Bai.

Etymology. The specific name is derived from the Latin cyclo- and punctatus, referring to the round punctures on the pronotum.

Distribution. China (Ningxia).
