Lasiocolpus sinuaticollis Reuter, 1884

( Fig. 268 )

Lasiocolpus sinuaticollis Reuter, 1884: 28 .

Diagnosis: Characterized by its large size, reduced left paramere, dark hemelytra and II antennal segment 3.5x longer than I.

Redescription: Measurements, see Table VII. Male: Dorsal aspect: Body oval-oblong. General coloration pale except darker antennal segments I and II, extreme base of corion and reduced spot on internal angle of cuneal fracture. Pilosity suberect, sparse, very long. Head: Eyes small; anteocular region longer than eye length. Proportion of antennal segments (I:II:III:IV) 1: 3.7: 2.7: 2.3. Labium with second segment reaching midcoxae, III reaching hindcoxae. Thorax: Pronotum with lateral margins very sinuate, carina well marked on apical half; posterior margin deeply concave; collar wide; calli medium-sized and protuberant; posterior lobe punctured, slightly wrinkled ( Fig. 286 ). Hemelytra with lateral margins moderately sinuate, extending beyond the abdomen; length and width at base of cuneus subequal; length of membrana, from tip of cuneus, approximately equal to length of cuneus ( Fig. 288 ). Ventrally light brown, except blackish mesopleura. Pilosity long, adpressed, sparse. Foretibiae with a row of teeth; pads vestigial ( Fig. 287 ); midtibiae without spines. Metasternum sulcate medially ( Fig. 289 ). Abdomen: Dense small punctures only present on laterotergite II. Hairs on dorsal surface of abdomen short, sparse, with row of longer setae on apical margin of each segment. Genitalia: Pygophore ( Fig. 290 ) with right paramere present; left paramere ( Fig. 291 ) less than half the width of pygophore, distally pointed. Female: Similar to male in coloration and dimensions. Proportion of antennal segments (I:II:III:IV) 1: 3.6: 2.8: 2.6.

Distribution: Guatemala, Mexico, Panama ( Fig. 270 ).

Material examined: Holotype; ♀, Mexico, Veracruz, D. Sallé. SMNH GUATEMALA: ♂ and ♀, Cerro Zunil, L. sinuaticollis , 4–5000 ft. BMNH; MEXICO: ♂, Laredo , Tex., Tamazunchale, S.L.P., 8-15-52 920, Phylodendron seedlings. USNM.

Discussion: It differs from L. minor , which is the nearest species, by its size, presence of a right paramere and shape of left paramere.
