Reitman leg.; 1 ♀ ( UB), 25/IX/1952, Atacama Chacritas, Kuschel leg.

Diagnosis. Prosaspicera aterrima is similar to P. joani n. sp. and P. sinuosa because the scutellar spine has a strong sulcus between prominent longitudinal carinae, and also because of the transverse carinae on the mesoscutum ( Figs 29 & 31a). The scutellar foveae in P. joani n. sp. have a posterior margin whereas in P. sinuosa and P. aterrima the margin is absent ( Fig. 29). In P. aterrima the occipital carina is angled behind dorsal 1/3 of the eye; gena very expanded, shining, with strong transverse carinae ( Fig. 30a); ocelli slightly prominent; parascutal sulcus very wide and contacting with anterior end of notauli, in some specimens it is getting weaker and narrower towards anterior end; the scutellar spine is long ( Fig. 29a).

Redescription. Length. Females 3.3–3.8 mm.; males 3.8–4.2 mm.

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

Head. Frons coarsely rugose and weakly 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 shining, with two longitudinal carinae on each side of median vertical groove, which is smooth. Ocelli slightly prominent. Occiput smooth and shining, with 3 or 4 transverse carinae usually discontinuous centrally.

Antenna. MALE. Almost filiform, flagellomeres slightly wider centrally. Antennal formula: 4.5(3): 2(2.5): 6(2.9): 5.5(2.5): 5.8(2.9): 5.5(2.5): 5(2.5): 5(2.5): 5(2.5): 5(2.5): 5(2.3): 4.5(2.2): 4.5(2.2): 7.2(2.2). FEMALE. Very weakly subclavate. Antennal formula: 4(3): 2(2.5): 5.5(2.9): 5(2.5): 5.5(2.9): 5.5(2.5): 5(2.5): 5(2.5): 5(2.5): 5(2.5): 5(2.3): 4.5(2.2): 7(2.2).

Mesosoma. Lateral surface of pronotum finely granulate on ventral half and granulate-rugose dorsally; densely pubescent. Subpronotal plate weakly rugose and densely pubescent laterally, smooth and glabrous centrally. Mesoscutum quite densely pubescent, coriaceous and coarsely carinated transversely between notauli. Anteroadmedian lines prominent, reaching 1/3 to 1/2 the length of mesoscutum, parallel; median ridge prominent, not divided before median mesoscutal furrow. Notauli wide, wider on posterior 1/2, very weakly carinated transversely. Median mesoscutal furrow weakly sculptured in anterior part, smooth and polished in posterior part. Area between notauli and end of median mesoscutal furrow little prominent. Parascutal sulcus very wide, smooth, pubescent and continuing to anterior end of notaulus, in some specimens weak and narrow from tegula to anterior end of notauli. Mesopleura smooth or weakly alutaceous in anterior part. Scutellum 1.57 to 1.65 times length of scutum. Scutellar foveae big, heart-shaped, shallow, smooth and without posterior margin; interfoveal line and lateral carinae prominent and going on along the spine. Surface of scutellum without sculpture. Scutellar spine, in lateral view, in same plane as scutellar foveae, quite curved and almost reaching the Rs of wing.

Wings. Forewing membrane hyaline. Radial cell 1.89 to 2.40 times longer than wide. Marginal pubescence absent. R1 very short but conspicuous, Rs very curved near margin of wing.

Biology. Unknown.

Prosaspicera atra Díaz, 1979

( Figs 23b & 24b)

Prosaspicera atra Díaz, 1979: 102 .

Diagnosis. Prosaspicera atra is easy to differentiate from the other species of Prosaspicera that lack transverse carinae inside of the notauli; P. atra has scutellar foveae deep and heart-shaped ( Fig. 23b), occipital carina strongly angled behind dorsal 1/3 of eye ( Fig. 24b), gena strongly expanded (coriaceous with strong transverse carinae and glabrous), vertex widely incised, ocelli conspicuously prominent, mesoscutum with scattered setae (coriaceous and with some punctuate sculpture) and scutellar spine on same plane as scutellar foveae and long ( Fig. 23b).

Redescription. Length. Female 4.5 mm.; male unknown.

Coloration. Head, antenna, mesosoma and metanotum entirely black. Legs dark brown to black, forelegs lighter.

Head. Frons coriaceous. Lateral frontal carinae raised, well developed, area between carinae and eye coriaceous. Occipital carina strongly angled behind dorsal 1/3 of eye. Gena strongly expanded, coriaceous with conspicuous transverse carinae, glabrous. Vertex widely incised, shining, weakly coriaceous, posterior part shining centrally, coriaceous laterally, with one longitudinal carina on each side of median vertical groove, which is smooth. Ocelli conspicuously prominent. Occiput shining and coriaceous laterally, delimited with one transverse carina.

Antenna: Filiform. Antennal formula: 5(3.8): 2.1(3): 8(3): 7(3): 7(3): 7(3): 6.8(3): 6(3): 6(3): 5(3): 5(3): 5(3): 10.2(3).

Mesosoma. Lateral surface of pronotum finely coriaceous, with strong carina near lateral margin of subpronotal plate, sparsely pubescent. Subpronotal plate coriaceous and with scattered setae laterally, weakly coriaceous and glabrous centrally. Mesoscutum with scattered setae, coriaceous and weakly punctuated. Antero-admedian lines prominent, surpassing 1/3 and ending before the 1/2 of mesoscutum length, confluent; median ridge prominent. Notauli smooth and wide. Median mesoscutal furrow smooth. Area between notauli and end of median mesoscutal furrow prominent. Parascutal sulcus very wide, smooth and glabrous, continuing to anterior end of notauli. Scutellum 1.79 times length of scutum. Scutellar foveae heart-shaped, deep, with small oblique carinae in posterior part, posterior margin formed by two strong oblique carinae. Interfoveal line prominent and continuing to the last 1/4 of the spine. Lateral carinae prominent and marked to last 1/3 of spine. Scutellar disc and spine coriaceous. Scutellar spine on same plane as scutellar foveae, almost straight and reaching the 1/2 of radial cell of wing.
