Diagnosis.
Among species of the
neotropicus
group
sensu
Michener (2007)
,
L. rosellae
can easily be recognized by the following combination of characters: female inner metatibial spur with few, elongate branches; scutum in both sexes uniformly punctate, with coarse punctures separated by a puncture width or less (
Figs. 15, 18
); female metasomal terga largely impunctate, with minute, faint, scattered punctures, without integumental or apical hair bands (
Fig. 17
); body pubescence largely ferruginous in the female (
Fig. 15
), in the male restricted to pronotal lobe, scutum, and scutellum (
Fig. 18
); and female tibial scopa with sparse, long (2.5–3.0 times median ocellar diameter), apically branched hairs.
Description (Male).
As in the female (cf.
Gonzalez & Florez 2011
), except: Body length
6.9 mm
; forewing length
4.8 mm
; head width
2.1 mm
. Head 1.3 times wider than long; inner orbits of compound eyes converging below (
Fig. 20
); intertorular distance 2.3 times median ocellar diameter, 1.8 times length of torulorbital distance; torulus diameter slightly narrower (0.8 times) than median ocellar diameter; ocellocular distance 1.8 times median ocellar diameter; interocellar distance about 1.8 times median ocellar diameter; clypeus about 1.7 times broader than long; gena about 0.5 times width of compound eye in profile; scape 3.2 times longer than broad; antennal flagellum more than three times longer than scape; pedicel about as long as broad; first flagellomere about twice as long as second, slightly longer than third. Inner metatibial spur straight, ciliate as in outer spur. Sixth to eighth sterna and genital capsule as in figures 22–28.
Color generally as in female except legs and metasoma largely dark brown to black.
Pubescence shorter and sparser than in female, except as follows: clypeus and inferior paraocular area with dense, minutely branched, silver hairs; legs and metasoma with whitish hairs; discs of second and third metasomal terga with short (at most one-third median ocellar diameter), simple, erect hairs.
Integument with coarser and denser punctures than in female, particularly on head and metasomal terga.
Examined material.

Comments.
This species was previously known from the female
holotype
, which is in somewhat poor condition. The male of
L. rosellae
agrees in most characters with those of the female, except in the usual secondary sexual features, the shorter, sparser body pubescence and the integument with coarser and denser punctures, particularly on head and metasomal terga.
