Mesoepinotal constriction deep. Base of epinotum, which 
is nearly twice as long as the declivity, is in profile rounded 
as it rises from the suture, then flat for the rest of its 
length. Declivity concave, separated from the base by a 
transverse ridge ending in a point on either side. First 
joint of pedicel from above longer than broad, the sides 
parallel, the node ending in front in a blunt point ; in pro- 
file the joint is divided into two halves by the point, in 
front of this point it is concave, beyond plane. Under- 
neath is a blunt tooth directed forwards. Second joint 
once and a half as wide as first, broader than long, with 
convex sides, in profile it is higher behind, where it is 
rounded and higher than first joint. Underneath in front 
is a blunt tooth. 
Femora very swollen. Gaster ovate. 
Back of head and thorax shining, front of head and 
gaster mat. Mandibles closely striate. Clypeus sub-mat, 
with two or three strong ridges at the sides and some 
indistinct ones in between. Head closely and evenly longi- 
tudinally striate. On the cheeks the striz tend to become 
coarse reticulations. There is a reticulate ground-sculpture 
between the striz, except on the vertex and occiput, which 
are shining between the striz. Promesonotum coarsely 
longitudinally rugose and shining, likewise the sides. 
First half of base of epinotum irregularly transversely 
rugose, second half regularly so. Declivity shining. First 
node irregularly rugose, second evenly longitudinally rugose. 
Base of gaster with fine, longitudinal, short strie, the rest 
superficially reticulate.

According to Forel’s description, it also comes near ode, 
which I have not seen.
