Prosaspicera mariarrosae Ros-Farre & Pujade-Villar 2006, n. sp.

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

(Figs 17b & 18b)

Type material: (2 ♀). HOLOTYPE female (USNM), 9/ 16-I- 1992 in Orizaba (MEXICO), H. Osborn col. PARATYPE: 1 ♀ (MZRJ), 1936 in Angra E. do Rio (BRAZIL), L.TR. V. E Lopes col.

Diagnosis. Prosaspicera mariarrosae is easily recognized because the end of the median ridge is raised as a tooth (Fig. 18b); P. dentata is also recognized by a tooth at the end of median ridge but the scutellar spine is long and curbed while in P.mariarrosae it is short and straight. Moreover, the frons is coriaceous with some small carinae centrally, occipital carina angled behind the dorsal 1/3 of eye, gena expanded and coriaceous, vertex strongly incised and flat centrally, ocelli conspicuously prominent, lateral surface of pronotum coriaceous and slightly punctuate, mesoscutum coriaceous and forewing without marginal cilia.

Description. Length. Females 2.7–3.6 mm.; male unknown.

Coloration. Head black. Mesosoma black in anterior part and reddish black laterally. Metanotum reddish black. Antenna and legs medium brown.

Head. Frons coriaceous with some small carinae centrally. Lateral frontal carinae strong, area between them and eye with very weak transverse carinae. Occipital carina angled behind dorsal 1/3 of eye. Gena expanded, coriaceous, with scattered setae. Vertex strongly incised, flat centrally, smooth and shining, in posterior part shining, weakly striated with one longitudinal carina on each side of median vertical groove, which is smooth. Ocelli conspicuously prominent. Occiput shining, weakly striated, with short transverse carina.

Antenna. Slightly subclavate. Antennal formula: 5(3): 1.6(2.2): 5(2): 5(2): 5(2): 4.5(2): 4.5(2): 4.5(2): 3.5(2): 3.5(2): 3.5(2): 4(2): 8(2).

Mesosoma. Lateral surface of pronotum coriaceous and slightly punctuated, sparsely pubescent. Subpronotal plate coriaceous, pubescent laterally, glabrous centrally. Mesoscutum sparsely pubescent and coriaceous. Antero-admedian lines prominent, reaching between 1/3 and 1/2 length of mesoscutum, almost parallel; median ridge strongly prominent not divided, forming a tooth before median mesoscutal furrow. Notauli wide, smooth. Median mesoscutal furrow smooth. Area between notauli and end of median mesoscutal furrow conspicuously prominent. Parascutal sulcus very wide, smooth, glabrous, continuing to anteiror end of notauli. Mesopleura smooth. Scutellum 1.16 times length of scutum. Scutellar foveae longitudinally oval, rather deep, smooth in posterior part and with effaced sculpture in anterior part, with posterior limit; interfoveal line strong and going onto last 1/3 of scutellar spine, lateral carinae absent. Scutellar disc and spine coriaceous. Scutellar disc, in lateral view, on same plane as basis of scutellar spine, which is slightly sloping towards apex and reaches almost the basal vein of wing.

Wings. Wing membrane hyaline. Radial cell 2.14 times longer than wide. Marginal pubescence of wing absent. R1 very short practically absent. Rs very slightly curved.
