Diagnosis. The new species clearly differs from Ceropales (C.) ligea Bingham, 1903 (from the Oriental, Palearctic and Australo-papuan regions) in the C. helvetica -group and other congeners by combination of characters detailed as follow:

Description. Female ( Fig 1. b ). Body length 7–9 mm, fore wing length 6.7 mm. Black; yellowish white: labrum except black spot medially, clypeus except black spot medially, lower frons, streak on inner margin of eyes to ocular sinus, spots on antennal joints 1–2 below, spot between antennal sockets, interrupted line on outer eye margin, pronotal tubercle, posterolateral angle of pronotum, spot on metanotum medially, lateral corner of propodeum, spot on fore face of fore coxa, small spot on outer face of mid and hind coxae apically, inner lateral margin of all trochanters apically, small spot on outer face of fore and mid femurs apically, spot on outer face of fore tibia apically (sometimes absent), spots on both side of gastral terga 1–3 subapically, and a large spot on tergum 6; mandible apically, flagellum joints 1–2 beneath (sometimes only flagellum joint 1 below), most part of fore tibia, hind femur (black on both apical margin) ferruginous ( Fig 1. b ). Wings hyaline, brownish, veins dark brown. Body covered with silky pubescence.

Head. Labrum exposed. Mandible bidentate apically. Clypeus short, slightly convex in lateral view, anterior margin nearly straight, slightly emarginated medially ( Fig 3. a ). Frons and vertex with adjacent, small punctures mixed with sparse, shallow punctures on upper frons, and some deeper and densely set punctures only along inner eye margin above ( Fig 3. b ). Frontal line shallow, extending to anterior ocellus. Ocelli in acute triangle, ocellar area elevated ( Fig 3. c ). Frons conspicuously elevated between antennal sockets, slightly curved before antennal sockets and upper frons bent in obtuse-angle on 2/3 away from antennal sockets in lateral view ( Fig 3. d ). Orbital groove shiny, well developed, beyond the half length of outer eye margin ( Fig 3. d ). HW: HL = 86: 49; POD: OOD = 12: 17; length ratios of scape, pedicel, flagellomere I–IV and IX–XI = 15: 10: 18: 18: 18: 18: 18: 20.

Mesosoma . Pronotum with shallow, scattered punctures dorsally, anterior area with tuberculate prominence laterally, both lateral sides vertically impressed medially and with short, longitudinal rugae in impression, anterolateral angle acute, posterolateral angle rounded ( Fig 3. e ), posterior margin slightly arcuate. Mesonotum with shallow, scattered punctures, and their interspaces much larger than their diameters, parapsidal furrow extending from posterior margin to 2/3 length of mesonotum; mesopleuron with scattered punctures; some dense and deep punctures set below the tegula, nearly 2 × diameters apart ( Fig 3. e ). Scutellum with prescutelar sulcus, median area conspicuously elevated and with fine punctures; short, longitudinal rugae laterally. Metanotum conspicuously elevated medially, slightly longitudinal concave at apex and polished; with short, longitudinal rugae laterally. Postnotum slightly broadened medially and narrowed laterally, with few transverse rugae, shiny. Propodeum conspicuously flat in its entire length in lateral view ( Fig 3. e ), surface with microscopically fine transverse rugulosity, medial sulcus reaching half-length of propodeum and transversely clathrate, posterior margin nearly straight, posterolateral angle of propodeum rounded ( Fig 3. f ), lateral side of propodeum with a conspicuous, deep oblique suture medially, with fine, sparse punctures below suture ( Fig 3. e ).

Legs. Tarsal claws (except hind tarsal claw) normal, slightly curved apically, with a short, erect and acute subapical tooth.

Wings. Fore wing upper margin of submarginal cell III obviously shorter than submarginal cell II, lower margin of submarginal cell III obviously longer than lower submarginal cell II; submarginal cell II receiving crossvein 1m-cu medially; submarginal cell III receiving crossvein 2m-cu medially. Vein A and crossvein cu-a of hind wing forming obtuse angle, M + CuA diverging after cu-a ( Fig 3. h ).

Metasoma. Short and fusiform. Last sternum strongly compressed laterally, lower margin flat in lateral view, pointed apically ( Fig 3. g ).

Male ( Fig 1. c ). Differs from female as follows: body length 6 mm, fore wing length 5.8 mm. Spot on tegula white; lower side of antennal last four joints ferruginous. HW: HL = 72: 44 ( Fig 4. a ); POD: OOD = 13: 19; A1: A2: A3: A4: A5: A6: A12: A13 = 14: 9: 15: 15: 15: 15: 13: 17. Fore tarsomeres II–IV normal, tarsomere V large, inner side deeply emarginated medially; inner claw of fore tarsus very deeply split owing to unusually large, not truncate inner tooth basally ( Fig 4. b ); other claws of fore and mid tarsi normal, slightly curved apically, with a short, erect and acute subapical tooth; claws of hind tarsus rectangularly curved. Gastral sternum 9 distinctly longer than width and raised like a roof longitudinal medially, broadly rounded apically and with a tuft of erect long hairs ( Fig 4 . c–d). Paramere in genitalia conspicuously dilated and expanded apically, outer side with rigid, erect and scattered setae ( Fig 4 . e–f).
