Lasiocolpus vivianai n. sp.

( Fig. 235 )

Diagnosis: Characterized by the combination of the following characters: homogeneous brown dorsal coloration, small size, posterior lobe of pronotum deeply punctured, large eyes with narrow interocular space, the left paramere short with external margin straight and the internal margin sinuate.

Description: Measurements, see Table VII. Male: Dorsal view: Body oblong-oval. General coloration unicolorous dark brown, with legs testaceous. Pilosity dense, semierect, mediun sized. Posterior lobe of pronotum strongly punctured; calli shiny. Head: Shiny. Anteocular region almost as long as or subequal to eye length. Antennal segments (I:II:III:IV) 1: 3.5: 2.7: 2.5. Labial segment II reaching midcoxae, III slightly surpassing hindcoxae. Thorax: Pronotum with lateral margins slightly sinuate, well carinate on their apical 2/3; collar thick, posterior margin slightly concave; calli large and protuberant; posterior lobe densely punctured, mostly at central area ( Fig. 244 ). Hemelytra with lateral margins slightly sinuate at apex of embolium, surpassing apex of abdomen; cuneus as long as wide; membrane from tip of cuneus, longer than length of cuneus ( Fig. 247 ). Foretibia armed with a row of small teeth; pads obsolete ( Fig. 245 ); mid- and hindtibiae without teeth. Metasternum elongate, apically acute and sulcate medially ( Fig. 246 ). Abdomen: Laterotergites II and anterior half of III with dense small punctures ( Fig. 250 ). Setae on dorsal surface of abdomen short, sparse, with an irregular row of longer setae on apical margin of each segment; sixth abdominal segment with grouping of copulatory teeth, rounded on apical left margin ( Fig. 251 ). Genitalia: Pygophore ( Fig. 252 ) with right paramere vestigial; left paramere short, with external margin straight and internal one sinuate; apically pointed ( Fig. 253 ). Female: Similar to male in coloration. Head: proportion of antennal segments (I:II:III:IV) 1: 3: 2.2: 2.2. Genitalia ( Fig. 254 ).

Distribution: Nicaragua. ( Fig. 240 ).

Material examined: Holotype: ♂, NICARAGUA: Zelaya , Río Las Latas, 2-6- 97, 220 m (ols), J. M. Maës — Hernandez. MACN ; Paratypes: 2♂, 2♀, same data. MACN, MLEN ; ♂ ♀, same data, slide mounted. MACN .

Discussion: This species is nearest to L. minor , but can be easily distinguished by its homogeneous dorsal coloration, as well as by the left paramere, which has a straight outer margin.

Etymology: The specific name is dedicated to the author’s wife, Viviana M. Justo, who has recently died (November 2012).
