Eusolenophora testaceoides n. sp.

( Fig. 178 )

Diagnosis: This species can be recognized by the following combination of characters: brachyptery, left paramere curved and with a short prominence on the outer margin.

Description: Measurements, see Table V. Male: Dorsal view: Brachypterous. Hemelytra not surpassing fourth abdominal segment. General coloration testaceous, head darker, blackish. Dorsal setae short, thick, setae longer on head, margins of pronotum and exocorion. Head: Smooth, a little prolonged anteriorly from base of antennae; ocelli small, interocular space wide ( Fig. 188 ); antennal segment II gradually thickening towards apex, and longer than head. Antennal segments (I:II:III:IV) 1: 2.6: 2.0: 1.6. Thorax: Pronotum small, flattened, with lateral margins straight, rounded anterior angles, and posterior margin concave; pronotal lobes smooth, not well delimited ( Fig. 189 ); foretibiae armed with a few (3–4) very long spines ( Fig. 190 ); forefemora slightly widened, unarmed; pads well developed. Hemelytra with characteristic punctures with a seta emanating from each ( Fig. 192 ). Meso- and metasternum not sulcate medially ( Fig. 191 ). The last elongate apically, with extreme apex widened. Abdomen: Hairs on dorsal surface noticeable on outer margins, sparse centrally. Sixth abdominal segment without grouping of copulatory teeth on left apical margin. Genitalia with pygophore ovoidal ( Fig. 193 ); left paramere short, wide, curved inward, acute apically; outer margin with small prominence on subapical portion ( Fig. 194 ). Female: Similar to male in coloration and measurements. Antennal segments (I:II:III:IV) 1: 2.7: 2.1: 1.9.

Distribution: Argentina. ( Fig. 37 ).

Material examined: Holotype ARGENTINA: ♀ Tigre , Viana. MACN ; Paratypes ♂ Idem (slide-mounted). MACN ; ♂ Buenos Aires, I. Talavera, Zárate, 30-X-2004, Carpintero. MACN ; ♀ Pereyra , X-1963. MACN ; ♀ Santa Fe, Fives Lille, Weiser. MACN .

Etymology: The specific name refers to similarities with the known species E. testacea .

Discussion: This is the only brachypterous species of this genus in South America and was found in central Argentina, in temperate areas of this country. Author collected a male under the bark of a decayed floral stem of Eryngium sp. (Apiaceae-Umbelliflorales) in Talavera Island.
