mandibles triangular with dentate masticatory border. Frontal 
carinae long and straight, not forming scrobes for hiding the 
antennal scapes. Epinotum with two long spines. Petiolar 
nodes rounded above, low, petiole with a conspicuous ventral 
tooth, postpetiole with a long spine. The femora somewhat 
swollen. Erect hairs of the body long, fine, pubescence only 
present in legs and scapes. Wings with reduced venation, with a 
long, closed cubital cell. 
“Male: Antennae 13-jointed, the long, slender scape over- 
reaching the occipital margin, club 4-segmented, not shorter 
than the remainder of the funiculus. Eyes very large, convex. 
Masticatory border of mandibles dentate. Thorax narrow, with 
Mayrian furrows and strong epinotal spines. Hairs and wings 
as in the female.” 
The description of the new species, L. spinosa, contains some mea- 
surements of the holotype J: 
“Head length 0.85 mm, width 0.70, scape length 0.60, length of 
eye 0.30, thorax length 1.15, width 0.60, height 0.70, length of 
petiole 0.30, width 0.29, height without ventral tooth 0.36, 
postpetiole length 0.30, width 0.47 mm. 
“Female: Head elongate, 1.5 times longer than wide, with 
nearly straight lateral margins, with distinct anterior and more 
rounded posterior corners. Eyes much larger than the genae. 
Clypeus moderately vaulted, slightly concave in the middle of 
the anterior margin, with an indistinct central carina. Frontal

club 3-segmented, only slightly shorter than the remainder of 
the funiculus. Last segment (like in the male) about the length 
of the two preceding ones together. Scape not fully reaching 
the occipital margin. Segment 3 to 7 of funiculus wide, not 
longer than wide. The long frontal carinae reaching behind the 
hind margin of the eyes. Thorax slender, elongate, somewhat 
flat above, anterior part of mesonotum narrowing, not cover- 
ing the pronotal shoulders. Epinotal spines strong, longer than 
half their basal distance. Petiole short, massive, in profile with 
descending anterior and rounded upper surface, with a big
