Prosaspicera sinuosa Díaz, 1984

( Figs 5c, 6f, 29b & 30b)

Prosaspicera sinuosa Díaz, 1984: 237–238 .

Type material: ( 1 ♂). HOLOTYPE male deposited in MLP (La Plata, Argentina), nº 020

( Díaz & Loiácono, 1995), 30-I-1968, Salta: Piedra de Molino ( ARGENTINA) Golbach col.

Additional material. (2 ♂). CHILE: 1 ♂ ( UB), 8/ 11-XI-1961, Coquimbo, Rio Los Molles. L. Penna leg. ; 1 ♂ ( CNCI) 28-X-1952, Rivadavia, Coquimbo, L. E. Peña leg.

Diagnosis. Prosaspicera sinuosa is similar to P. aterrima and P. joani because the scutellar spine has strong longitudinal furrows and the mesoscutum is transversely carinated. It can be differentiated from P. joani because the scutellar foveae have posterior margin in P. joani ( Fig. 31a), but not in P. sinuosa ( Fig. 29b). And from P. aterrima ( Fig. 29a) by the length of scutellar spine that is shorter in P. sinuosa ( Fig. 29b). Moreover, P. sinuosa has the occipital carina angled behind the dorsal 1/3 of eye, the gena strongly expanded, shinning and with coarse transverse carinae, the ocelli slightly prominent, the parascutal sulcus narrow and weak from tegulae to anterior end of notauli and the scutellar spine rather short.

Redescription. Length. Males 3.2–4.0 mm.; female unknown.

Coloration. Head, mesosoma and metasoma black. Scape and pedicellum black, antennomeres dark brown. Legs medium to black brown.

Head. Frons rugose. Lateral frontal carinae strong ventrally and weak dorsally, area between them and eyes with some transverse carinae. Occipital carina angled behind dorsal 1/3 of eye. Gena strongly expanded, shinning, with coarse transverse carinae, densely pubescent. Vertex weakly incised, rugose and shinning, in posterior part shining and coriaceous and with one longitudinal carina on each side of median vertical groove, which is faintly coriaceous to smooth. Ocelli slightly prominent. Occiput shining and coriaceous with several transverse carinae.

Antenna. Subclavate. Antennal formula: 5(3.5): 2(2.5): 7(2.5): 5(2.5): 5(2.5): 5(2.5): 4.5(2.5): 4.5(2.5): 4.2(2.5): 4.2(2.5): 4.2(2.5): 4.2(2.5): 4(2.5): 7(2).

Mesosoma. Lateral surface of pronotum granulated with small carinae on dorsal 1/2, densely pubescent. Subpronotal plate coriaceous and densely pubescent laterally, weakly coriaceous (almost smooth) and glabrous centrally. Mesoscutum rather densely pubescent, coriaceous laterally, with coarse transverse carinae and coriaceous-granulated sculpture between notauli. Antero-admedian lines prominent, reaching almost 1/2 the length of mesoscutum, almost parallel in posterior part; median ridge prominent, usually not divided before median mesoscutal furrow. Notauli smooth, shiny and narrowing towards anterior end. Median mesoscutal furrow smooth, sometimes with transverse carinae and rugose sculpture on anterior 1/3. Area between notauli and end of median mesoscutal furrow prominent. Parascutal sulcus narrow, smooth, with scattered setae laterally, weakly continuing to anterior end of notauli. Mesopleura smooth, very weakly coriaceous in anterior part. Scutellum 1.32 to 1.50 times length of scutum. Scutellar foveae transversely oval, big, shallow with weak longitudinal carinae and without posterior margin; interfoveal line and lateral carinae prominent until the end of scutellar spine. Scutellar disc coriaceous and with small carinae. Scutellar spine weakly coriaceous, with lateral carinae on each side of the median carina, between them there are deep furrows; in lateral view, spine is on same plane as scutellar foveae, strongly curved and extending to the space between basal and R1 veins of wing.

Wings. Wing membrane hyaline. Radial cell 2.0 to 2.2 times longer than wide. Marginal pubescence absent. R1 short, Rs curved.

Biology. Unknown.

Distribution. Neotropical. Originally recorded from Argentina; also from Chile in this study.
