Prosaspicera curvispina Ros-Farré

n. sp.

Prosaspicera curvispina Ros-Farré n. sp.

( Figs 2c, 5f, 35b & 36b)

Type material: ( 1 ♂). HOLOTYPE male ( CNCI), 14/ 16-IV-1986, Florida, Alachua co. , G. Gibson & Levi col., USA.

Diagnosis. Easily differentiated from all other species based on the following characters ( Figs 35b & 36b): scutellar spine straight on anterior 2/3, posterior 1/3 downwards directed; end of the scutellar foveae steeply sloping towards basis of scutellar spine; occipital carina strongly angled behind the dorsal 1/3 of eye; anterior margin of median mesoscutal furrow raised as a tooth; parascutal sulcus weak from tegulae to notauli; scutellar foveae wider than long.

Description. Length. Male 2.0 mm.; female unknown.

Coloration. Antenna and legs medium brown. Head, mesosoma and metasoma black.

Head. Frons coriaceous with strong frontal carinae, with longitudinal groove between frontal carinae. Lateral frontal carinae prominent, area between them and eyes with very small transverse carinae. Occipital carina strongly angled behind dorsal 1/3 of eye. Gena expanded, glabrous, almost smooth and with 2 or 3 transverse carinae. Vertex widely but weakly incised, coriaceous, in posterior part slightly coriaceous, with one longitudinal carina on each side of median vertical groove, which is smooth. Ocelli prominent. Occiput delimited with one transverse carina, slightly coriaceous.

Antenna. Filiform. Antennal formula: 8(5): 3(4): 9(3): 7.5(3): 8.5(3): 9(3): 8.5(3): 8(3): 9(3): 8(3): 7.5(3): 7(3): 7(3): 10.5(3).

Mesonotum: Lateral surface of pronotum coriaceous and sparsely pubescent, with strong transverse carinae on upper 1/3. Subpronotal plate coriaceous, with scattered setae laterally. Mesoscutum with scattered setae, coriaceous. Antero-admedian lines reaching more than 1/3 the length of mesoscutum and confluent. Median ridge not divided before median mesoscutal furrow. Notauli very wide, smooth and shining. Median mesoscutal furrow smooth and shining raised as a tooth on anterior margin. The area between notauli and end of median mesoscutal furrow prominent. Parascutal sulcus smooth and glabrous, narrow from tegulae to anterior end of notauli. Mesopleura smooth. Scutellum 1.96 times scutum length. Scutellar foveae very deep, smooth, shining, wider than long, anterior margin curved and ventral margin straight and prominent. Scutellar spine with median carina and lateral ones present on anterior 1/2 and with one deep furrow on each side of medial carina. Scutellar disc weakly coriaceous. End of scutellar foveae, in lateral view, steeply sloping towards basis of scutellar spine. Anterior 2/3 of the spine straight, posterior 1/3 downwards directed; spine almost reaching middle of radial cell of wing.

Wings. Forewing membrane hyaline. Radial cell 2.1 times longer than wide. Marginal pubescence absent. R1 absent, Rs slightly curved before margin of wing.

Derivatio nominis. Refers to the scutellar spine, which is very much curved in this species.

Biology. Unknown.

Distribution. Nearctic. Known only from Florida ( USA).
