Lasiochilus (Lasiochilus) colpoides n. sp.

( Fig. 195 View FIGURES 195–199 )

Diagnosis: Characterized by the left paramere apically strongly curved (90º), sexual pterygodimorphism, and wider interocular space.

Description: Measurements, see Table VI. Male: Dorsal view: Brachypterous. Oval, slightly flattened dorsally. General coloration pale brownish with hemelytra brown (excepting base of clavus and exocorion, pale brownish). Dorsal setae long, sparse, setae longer on head and margins of pronotum. Head: Smooth, shining, prolonged anteriorly nearly twice the length of one eye; ocelli reduced, interocular space wide ( Fig. 201 View FIGURES 201–214 ); antennal segment II slightly thickened towards the apex, and longer than head. Thorax: Pronotum small, shining, subquadrangular, flattened, with lateral margins slightly sinuate, rounded posterior angles and posterior margin a little concave; pronotal lobes smooth, not well delimited ( Fig. 202 View FIGURES 201–214 ). Forefemora slightly wide than those of the other species, unarmed; foretibiae armed with row of short teeth on apical 2/3 ( Fig. 203 View FIGURES 201–214 ); pads underdeveloped ( Fig. 204 View FIGURES 201–214 ); foretrochanters with 1–2 teeth on their inner margin ( Fig. 205 View FIGURES 201–214 ). Reduced hemelytra with characteristic punctures, with a seta emanating from each ( Fig. 207 View FIGURES 201–214 ). These reduced hemelytra reach the third abdominal segment, with a well-defined corio-claval suture. Metasternum elongate, wide apically, not sulcate medially ( Fig. 206 View FIGURES 201–214 ). Abdomen: Hairs on dorsal surface present as a central transverse row on each segment ( Fig. 213 View FIGURES 201–214 ). Sixth abdominal segment with grouping of slightly acute copulatory teeth, on apical left margin ( Fig. 208 View FIGURES 201–214 ). Genitalia: Pygophore ( Fig. 209 View FIGURES 201–214 ) with left paramere long, strongly curved (90º), acute apically ( Fig. 210 View FIGURES 201–214 ). Female: Macropterous ( Fig. 211 View FIGURES 201–214 ). Antennal segments (I:II:III:IV) 1: 2.5: 2.1: 2.0. Similar to male in coloration. Parietovaginal gland with double membrana as in Lasiocolpus ( Fig. 214 View FIGURES 201–214 ). Central punctures on seventh sternite inapparent ( Fig. 212 View FIGURES 201–214 ).

Distribution: Argentina. ( Fig. 200 View FIGURE 200 ).

Material examined: Holotype ARGENTINA: ♀ Misiones, P. N. Iguazú , X-1980, (at light), Carpintero coll. MACN ; Paratypes ♀ Idem (slide-mounted). MACN ; ♀ Idem (slide-mounted). MACN ; Entre Ríos, ♀ Camino a Los Talas , XII-1967. MACN ; ♂ Buenos Aires, I. Talavera, Zárate , XI-1996, M. Ramírez, (slide-mounted). MACN ; ♀ El Cazador, Escobar , (at light), I-1997, Carpintero, (slide-mounted). MACN .

Etymology: The specific name refers to the external similarities with genus Lasiocolpus .

Discussion: This species differs from L. pallidulus by its strongly curved left paramere, darker coloration, pilosity on abdomen as a single row of setae, and by its different measurements.
