Lasiocolpus elegans Reuter, 1884

( Fig. 236–237 )

Lasiocolpus elegans Reuter, 1884: 28 .

Diagnosis: Characterised by very pale coloration of corion, pilosity of the hemelytra and short, thick cuneus.

Redescription: Measurements, see Table VII. Male: Dorsal view: Body oblong. General coloration dark brown; corion brownish-yellow, except on preapical stripe; base of cuneus, apex of clavum and antennae dark. Pilosity long, erect, disperse. Head: Smooth, shiny. Eyes broad, small; ocelli large, interocular space wider than width of one eye; anteocular region longer than eye length ( Fig. 255 ). Second antennal segment, slightly thickened towards apex; antennal segments: (I:II:III:IV) 1: 3.7: 2.7: 2.6. Labial segment II, almost reaching midcoxae. Thorax: Pronotum laterally sinuate with a well-defined carina on apical half; posterior margin slightly concave; collar broad, smooth, shiny; calli protuberant and shiny; posterior lobe sparse and strongly punctured ( Fig. 256 ). Hemelytral sides sinuate, almost reaching apex of abdomen; cuneus basally wider than long; membrane from tip of cuneus longer than length of cuneus ( Fig. 259 ). Ventrally dark brown; two first segments of abdomen lighter. Pilosity long, not very dense, adpressed. Foretibiae armed with row of sparse short spiniform teeth on apical 2/3 ( Fig. 257 ); forefemora a little widened than the other ones, unarmed; pads underdeveloped; midtibiae without ventral row of teeth; all tibiae covered by fine, long pilosity. Metasternum apically narrow and medially sulcate ( Fig. 258 ). Abdomen: Hairs on dorsal surface present only on outer margins; ventrally sparse, short on three first urosternites and longer on the remainder; sixth abdominal segment with grouping of copulatory teeth, slightly acute on apical left margin ( Fig. 260 ). Genitalia: Left paramere short, with outer margin sinuate and internal margin straight ( Fig. 261 ). Female: Similar to male in coloration and measurements. Antennal segments (I:II:III:IV) 1: 3.7: 2.7: 2.6.

Distribution: Colombia, Bolivia. The species has also been newly recorded from Peru. ( Fig. 240 ).

Material examined: Holotype: ♀, COLOMBIA, Thieme, Typus, Lasiocolpus elegans Reuter, Mus. Zool. Helsingfors, Spec. Typ. # 10368. MZHF; PERU: ♂, Cusco, San Martín 2, Base Pluspetrol, II-06, J. Williams. 72º46’53’’W – 11º46’17’’S, Malaise trap (Slide-mounted). MACN; BOLIVIA: ♀, El Palmar, Chapare, Cochabamba, 1000 m., 10/ 18-X-1958, Monrós y Wygodzinsky. MACN.

Discussion: This is one of the two species for which Reuter erected this genus. He described it on the basis of a single female. It differs from the remainder species of the genus by the shape of the left paramere (short with outer margin sinuate and internal margin straight), by coloration of hemelytra and long pilosity.
