Types.

, with the following label data: “

Diagnosis.
The following combination of character states distinguish this species: antennal club composed of six antennomeres; dorsal color testaceous, with head and pronotum darker and elytral disc infuscate (
Fig. 9
); head microreticulate (
Fig. 31
); male genitalia as in
Fig. 32-33
.
Description.
1.6 mm
long; elongate, parallel sided; dark testaceous, front of head slightly paler; antennae, legs, and elytra testaceous, disc of elytra infuscate (
Fig. 9
); ventral surface entirely testaceous.
Head:
Twice as wide across eyes as long; epistome with emargination over clypeus moderate, mandibular emarginations rather deep (
Fig. 31
), antennal emarginations barely indicated; frontoclypeal suture obsolete; longitudinal line impressed, anteriorly a little wider and deeper but not nearly so well-marked as in
L. buenavista
; moderately punctate, punctures much smaller than an eye facet, separated by 2-3 diameters, each subtending an inconspicuous, pale seta about twice a long as a puncture diameter; surface heavily microreticulate anteriorly and medially, smooth and shiny posterolaterally. Mandibles short, robust. Eyes large, about 0.5
×
length of head (
Fig. 31
). Antennae elongate, attaining basal third of elytra; scape oval, 1,4
×
longer than wide, pedicel subquadrate, 0.7
×
length of scape; III narrower, elongate, equal in length to scape; IV-V subquadrate, equal in length to pedicel; club comprised of VI-XI, VI-X about length of V, wider than long; XI elongate, twice as long as X.
Thorax:
pronotum transverse, 1.6
×
wider than long as across widest point just behind apical angles; 1.2
×
wider there than across basal angles; anterior angles obtuse, not produced; posterior angles obtuse, not produced; antebasal denticle distinct (
Fig 31
); sublateral line slightly broader medially but not foveate; punctation and pubescence similar to head; surface between punctures smooth and shiny, not microreticulate; legs short, femora robust.
Elytra:
1.5
×
longer than combined width; inner margin of cell 1 grooved at posterior half and shallowly grooved for anterior fourth; inner margin of cell 2 grooved at apical three-fourths; cell 3 complete; humeral carina well marked; elytra declivous laterally, narrowly explanate; surface minutely punctate and inconspicuously pubescent.
Male genitalia:
parameres attenuate apically (
Fig. 32
), but less so than in
L. buenavista
,
not separated; basal plates elongate-oval in shape, not truncate basally (
Fig. 32
); flagellum longer than basal strut, apically bifurcate, with microspinose processes (
Fig. 33
); claspers similar to
L. buenavista
but narrower and more elongate (
Fig. 32
).
Female
allotype
:
1.7 mm
long; eyes proportionally larger, 0.7
×
length of head; pronotum less narrowed posteriorly.

The
two male
paratypes
are both
1.4 mm
in length.

Etymology.
The specific epithet is Latin for “neat” or “elegant.”
Discussion.
This appears to be the least common and geographically most restricted member of this group of
Laemophloeus
, being represented by only
four specimens
from two countries.
