Prosaspicera joani Ros-Farré & Pujade-Villar

n. sp.

Prosaspicera joani Ros-Farré & Pujade-Villar n. sp.

( Figs 31a & 32a)

Type material: ( 1 ♂). HOLOTYPE male ( CAS), 6-XII-1950, Coquimbo Prov., 5 miles N Laguna Dam. , 8000 ft. elev., CHILE, Ross and Michelbacher col.

Diagnosis. Prosaspicera joani is similar to P. aterrima and P. sinuosa because the scutellar spine has strong longitudinal furrows, and the mesoscutum is transversely carinated. The scutellar foveae have posterior margin in P. joani ( Fig. 31a) and are not in P. sinuosa ( Fig. 29b) and P. aterrima ( Fig. 29a). Moreover, P. joani has the occipital carina angled behind the dorsal 1/3 of eye, the gena very expanded, shining, with strong transverse carinae, the ocelli slightly prominent, the parascutal sulcus narrow and the scutellar spine short.

Description. Length. Male 3.2 mm; female unknown.

Coloration. Head and mesosoma black, metanoutm dark. Antenna brown. Legs brown to black.

Head. Frons with coarse rugose sculpture and coriaceous. Lateral frontal carinae prominent, area between them and eye with transverse carinae and coriaceous. Occipital carina angled behind dorsal 1/3 of eye. Gena very expanded, shining, with conspicuous transverse carinae and sparsely pubescent. Vertex little concave, rugose and shining, in posterior part smooth and with one longitudinal carina on each side of median vertical groove, which is smooth. Ocelli slightly prominent. Occiput smooth and shining, with three strong transverse carinae discontinuous centrally.

Antenna. Weakly subclavate. Antennal formula: 4(3): 1.9(2.1): 6(2.5): 5(2.5): 5(2.5): 5.5(2.5): 4.5(2.5): 4.5(2.5): 4.5(2.5): 4.5(2.5): 4.5(2.5): 4(2.5): 4(2.5): 4.9(2).

Mesosoma. Lateral surface of pronotum finely granulate, densely pubescent. Subpronotal plate weakly rugose and densely pubescent laterally, smooth and glabrous centrally. Mesoscutum quite densely pubescent on anterior 1/2, sparsely pubescent in posterior part, coriaceous laterally, with coarse transverse carinae between notauli. Anteroadmedian lines prominent, reaching between 1/3 and 1/2 length of mesoscutum, strongly divergent in anterior part and parallel posteriorly; median ridge prominent, weakly divided before median mesoscutal furrow. Notauli rather wide, wider on posterior 1/2, with very weak carinae inside. Median mesoscutal furrow with very weak transverse carinae in anterior part, smooth in posterior part. Area between notauli and end of median mesoscutal furrow little prominent. Parascutal sulcus narrow, smooth, glabrous, continuing to anterior end of notauli. Mesopleura smooth. Scutellum 1.15 times length of scutum. Scutellar foveae big, strongly oval, shallow, oblique carinae in anterior part, with posterior margin; interfoveal line and lateral carinae prominent and going on along spine. Scutellum coriaceous. Scutellar spine with longitudinal strong carinae, in lateral view, in same plane as scutellar foveae, almost straight, slightly sloping towards apex; reaching area between basal and Rs veins of wing.

Wings. Forewing membrane hyaline. Radial cell 1.88 times longer than wide. Marginal pubescence absent. R1 very short but conspicuous, Rs slightly curved dorsally.

Derivatio nominis. Dedicated to Joan Ros i Poc, father of the first author.

Biology. Unknown.

Distribution. Neotropical. Known only from Chile.
