insertion near the midlength of the frontal carinae, the depression of 
the anterior part of the head and the relatively short flagellar seg- 
ments. Myrmotarsus includes massive and large species with 
depressed tibiae. Workers of Myrmamblys have heads that are 
longer than wide with parallel sides. The characteristics of Kara- 
vaievia are as follows: i 
Workers 
Apart from minimal variability, all workers are monomorphic 
and about 5.5 mm long. Head trapezoidal, with rounded occipital 
corners. Head sides convex, occipital margin more or less concave, 
and anterior margin mostly straight. The eyes are situated behind 
the midlength of the sides of the head. Length of head subequal to 
its width (i.e. Cl ~ 100). Clypeus narrow, convex, and without 
median carina. Its anterior margin almost straight, and in the mid- 
dle third slightly concave. Frontal carinae relatively short and sub- 
parallel to moderately divergent. Mandibles short, with lateral 
borders strongly curved and 5 teeth on each masticatory border. 
Antennal scapes projecting beyond the occipital margin by about 
one third of their length. Pedicel longer than the following flagellar 
segments; apical flagellar segments slightly thickened. Alitrunk with 
a deep impression (metanotum) between promesonotum and pro- 
podeum, and two raised stigmata at the deepest point of the impres- 
sion. Petiolar scale tapers to a transverse ridge. 
Females 
Total length about 1 1 mm. Head about twice as wide as that of 
the workers, and with less convex sides. Anterior clypeal margin 
with a median semicircular excision. Apical flagellar segments not 
thickened. 
Males 
Anterior clypeal margin straight. Mandibles with only one strong, 
apical tooth. Total outstretched length about 6.5 mm. 
Camponotus texens sp. n. 
Derivatio nominis: The species name is derived from the Latin 
word ‘texere’ = weave.
