Type material. Holotype: PERU: Madre de Dios: male, Pantiacolla Lodge, 8 km NE Mirador, Alto Madre do Dios River (12°38’23”S, 71°16’23”W), 950 m elevation, 24 OCT 2000, leg. R. Brooks, # PERU 1B00 0 83, collected under bark ( SEMC). Paratypes: PERU: 11 females with same data as the holotype ( SEMC, UIC).

Diagnosis. The new species resembles L. bolivianus and L. peruanus in the depressions at posterior angles of the pronotum having a matt surface. Lispinus blandus is distinctly larger than L. bolivianus and L. peruanus . The emargination at the posterior angles of the pronotum is similar to that of L. peruanus , but much more indistinct than that of L. bolivianus . Furthermore, the microsculpture of elytra and pronotum of L. bolivianus is denser and the surface is, thus, matter than in L. blandus .

Description. Body length 4.7 mm.

Body c olour black with front margin of clypeus reddish and antennae and legs dark brown.

Head 0.75 mm long, 0.85 mm wide; eyes small and not prominent; temples twice as long as eyes; clypeus smoothly rounded and widely margined, in particular in outer parts; with two supraocular setae, on each side two setae on the front margin of clypeus, one seta on the disc and one seta on the neck; punctation fine and sparse; distance between punctures on average twice as wide as diameter of punctures; clypeus more densely punctate than disc, but the punctation equally fine; on disc, a sparse and fine micro-punctation between coarser punctures and a moderately deep microsculpture longitudinally reticulate; surface slightly shiny.

Antennae thick and stout, slightly longer than head; antennomere 2 1.5 times as long as wide; antennomere 3 conical and not longer than antennomere 2; antennomeres 4 to 7 more or less quadrate; the following antennomeres nearly twice as wide as long.

Pronotum 0.77 mm long, 0.87 mm wide; widest at anterior angles; straightly narrowed to posterior angles; front edge deeply emarginate and, therefore, front angles distinctly prominent; several setae along lateral margin; four of them much longer than the rest; another long seta at front edge near front angles; punctation much coarser and denser than on head; distance between punctures on average as wide as or shorter than diameter of punctures; a fine micro-punctation also present; a narrow midline without punctures; microsculpture deeper than on head, but longitudinally reticulate, too; surface less shiny than head; depressions at posterior angles deep and distinctly margined laterally; with microsculpture denser than on the disc, thus, rendering the depressions dull.

Elytra 1.05 mm long, 0.90 mm wide; punctation slightly finer and sparser than on pronotum, but larger and denser than on head; microsculpture deep and densely longitudinally reticulate; surface distinctly duller than in pronotum and head; with two short indistinct setae on the disc near suture, one in anterior half, one in posterior half.

Abdomen with punctation as dense and deep as on pronotum; microsculpture net-like reticulate; surface as shiny as in head; laterally with long yellow setae on each visible abdominal segment.

Etymology. The specific name is derived from the Latin word meaning nice.
