Prosaspicera costulata Ros-Farré n. sp.

( Figs 6a, 31b & 32b)

Type material: ( 1 ♂). HOLOTYPE male ( NHM), 17-V-1983, in Hainan I Tien Fong Mts. , ( CHINA), Boucek col.

Diagnosis. Easily differentiated from all other species because Prosaspicera costulata has a lot of special characters: gena and lateral surfaces of pronotum with strong carinae and without microsculpture ( Fig. 32b), parascutal sulcus very wide but very short, and scutellar spine weakly striated and very short ( Fig. 31b).

Description. Length. Male 5.2 mm; female unknown.

Coloration. Body entirely black. Antenna dark brown. Legs yellowish brown, last ones medium brown.

Head. Frons shining, with two carinae going from lateral frontal carinae and meeting on centre, below these carinae with strong oblique carinae. Lateral frontal carinae prominent, area between them and eye with weak transverse carinae. Occipital carina not angled. Gena expanded, glabrous, smooth, with strong transverse carinae. Vertex very much incised, shining and smooth, with one weak transverse carina, in posterior part alutaceous, with one longitudinal carina on each side of median vertical groove, which is smooth and shining. Ocelli conspicuously prominent. Occiput alutaceous.

Antenna. Filiform. Antennal formula: 4(2.8): 2(2.2): 6(2.4): 5(2): 5(2): 5(2): 5(2): 4.5(2): 4(2): 4(2): 4(2): 4(2): 3.9(2): 7(2).

Mesosoma. Lateral surface of pronotum glabrous shining and coriaceous, with conspicuous transverse and sinuate carinae. Subpronotal plate coriaceous, with scattered setae laterally, glabrous centrally. Mesoscutum with few scattered setae, coriaceous. Antero-admedian lines conspicuous, wide and prominent, reaching between 1/3 and 1/2 the length of mesoscutum, confluent and bounded by a sulcus, which has transverse carinae inside; median ridge weak and not divided before median mesoscutal furrow. Notauli wide, smooth. Median mesoscutal furrow smooth. Area between notauli and end of median mesoscutal furrow prominent. Parascutal sulcus wide, smooth, glabrous and in anterior part ending in front of tegulae. Mesopleura weakly striated. Scutellum 0.97 times scutum length. Scutellar foveae big, subquadrate, deep, slightly alutaceous and limited posteriorly by a carina; interfoveal line and lateral carinae absent on the spine, which is weakly striated. Surface of scutellar disc coriaceous, with a median carina. Scutellar spine, in lateral view, in same plane as scutellar foveae, straight, not reaching the basal vein of wing.

Wings. Forewing membrane hyaline. Radial cell 2.00 times longer than wide. Marginal pubescence sparse before Rs, getting dense towards lateral margin of wing. R1 absent; Rs straight, slightly curved near margin of wing.

Derivatio nominis. Refers to the strong carinae this species has in the lateral surface of pronotum and genae.

Biology. Unknown.

Distribution. Oriental. Known only from Hainan Island ( China).
