Diagnosis.
L. peruanus
resembles
L. bolivianus
in the small body size and the structure of the depressions at posterior pronotal angles. The shape of pronotum of
L. peruanus
is more or less quadrate, whereas that of
L. bolivianus
is distinctly wider than long. While the structure of the spiral endophallus resembles that of
L. bolivianus
, the paramera are distinctly different. Their stout shape with the separate transparent lobe is unique among the Neotropical
Lispinus
species.

Body colour
black with legs light brown and antennae dark brown; last abdominal tergite posteriorly reddish.
Head
0.45 mm
long,
0.50 mm
wide; eyes slightly prominent; front margin smoothly rounded; with two supraocular setae, two setae at the front margin and four setae on disc, two anterior discal setae at level of front edge of eyes, two posterior discal setae on neck; distance between posterior discal setae 1.5 times as wide as between anterior setae; punctation moderately fine and dense; distance between punctures on average about equal to diameter of punctures; a fine and sparse micro-punctation between the coarser punctures present; microsculpture distinct and dense, on clypeus net-like reticulate, on disc longitudinally reticulate; surface slightly shiny.
Antennae
as long as head and half the pronotum combined; 2nd antennomere globular; 3rd antennomere conical and slightly longer than 2nd; 4th antennomere as wide and long as 2nd; the following antennomeres increasing in width; 5th and 6th quadrate, penultimate antennomere 1.5 times as wide as long.
Pronotum
0.50 mm
long,
0.55 mm
wide; sides more or less parallel in front of short emargination at posterior angles; front edge slightly emarginate; with two setae along the lateral margin; punctures slightly larger, but as dense as on head; a fine and sparse micro-punctation present; impunctate midline narrow; microsculpture dense, but not deep; surface slightly shiny; with an indistinct longitudinal depression on each side of the midline and laterally a deep longitudinal depression at posterior angles; the lateral depression distinctly margined on each side with dense ground microsculpture, thus, surface of depression dull.
Elytra
0.70 mm
long,
0.60 mm
wide; punctures as deep and large as on pronotum, but slightly sparser; distance between punctures on average 1.5 times the diameter of punctures; laterally each with two rows of dense, deeply coriaceous punctures forming indistinct longitudinal rows; with dense and deep partly net-like microsculpture, partly longitudinally reticulate; surface dull.
Abdomen
with punctation as deep and dense as on pronotum; microsculpture net-like reticulate and distinctly weaker than on pronotum; surface distinctly more shiny than fore body.
Etymology.
The specific name is derived from the country’s name (
Peru
), where the species was collected.
