Head subcubical or more or less transverse; ocelli absent; frons not concave and without median keel; eyes small, with long and sparse hairs, without emargination opposite antennal sockets; occipital carina distinct and complete, fused with hypostomal carina; postgenal bridge very narrow; palpi formula 6-4; scape long and slightly flattened laterally, without apical lobe nor basal constriction (frontal view); first flagellar segment weakly curved and almost straight as long as second segment; mesosoma reduced; neck of promesosoma short or long; pronotal keel absent; anterior surface of mesonotum gently curved posteriorly and only very slightly raised above pronotum; notauli short, deep and complete; sternaulus shallow, wide, long, curved, coarsely crenulate; prepectal carina distinct, wide positioned high on mesopleuron; propodeum without marginate areas; medio-lateral tubercles more or less distinct and propodeal bridge present and narrow; fore tibia with numerous long spines arranged in narrow band;fore and mid femora with more or less distinct medio-lateral tubercles; hind tibia without spines on its outer distal margin and with small area of dense setae in inner distal part; hind coxa without basoventral corner and tooth; hind basitarsus 0.9-1.1 x as long as segments 2-5 combined; wings strongly reduced, present as small scales only; first metasomal tergite petiolate, long and narrow, without dorsope and basolateral processes; acrosternite long, about 0.7 x as long as first tergite; second suture indistinct; second and third tergite without furrows or defined areas; tergites 2-6 without separate laterotergites, with transverse submedian rows of long sparse hairs; ovipositor longer than metasoma, apex of dorsal valve with 2 small, widely separated nodes, apex of ventral valve serrate (from [1]).

It is probably closely related to Stephanospathius based on the presence of the strongly elongate acrosternite of the first tergite. But it differs from all members of Stephaniscini (Leptospathius, Schlettereriella and Stephanospathius) by the wings completely absent in female, a large propodeum, presence of two distinct latero-median propodeal tubercles, absence of any furrows or defined areas on second tergite, and a long first flagellar segment [1].
It differs from Leptospathius, Schlettereriella and Stephanospathius by the ocelli absent and the second tergum without any furrows [2].
It differs from Oroceguera by the propodeal tubercles distinct, the first flagellar segment distinctly longer than second segment, the propodeal bridge narrow, the acrosternum of first tergum long (0.7 times as long as tergum and the vertex and frons coarsely and densely rugose-reticulate [2].
It differs to many Spathiini (even if it is similar by the very long acrosternite) by the presence of propodeal bridge, long hind basitarsus, large propodeum, and usually long pointed scutellum.
