Unknown but the species known likely occurs in an enclosed, perhaps subterranean habitat [1].

Small size, 1.27 mm; female wingless.
Head subcubical flattened and glabrous dorsally; face with median keel and few long setae; eye small, longer than wide; ocelli absent; occipital carina meeting hypostomal carina; postgenal bridge absent; first flagellomere subequal but slightly shorter than second. Mesosoma highly modified and lacking tegula; pronotal collar equal in length to first flagellomere, pronotal carina distinct and raised; notauli present but short; scutellum conical and with distinct longitudinal carinae apically, coriaceous-rugose with tubercles on either side laterally; scuto-scutellar suture present; epicnemial carina distinct; postpectal carina present but less pronounced; sternaulus distinct; mesopleuron and metapleuron concave; deep sulcus dividing metanotum and propodeum; propodeum concave. Fore tibia and mid tibia with numerous obvious and stout spines along anterior edge; hind coxa without basal tubercle or tooth. Metasoma inserted high above hind coxal cavities and separated from them by a wide propodeal bridge; first metasomal tergite petiolate, acrosternite long, 0.5 times as long as first metasomal tergum, with distinct dorsope, without basolateral processes, spiracle found at about 0.5 length; longitudinal carinae present on tergum one, terga 2–8 without sculpture; distinct groove between second and third median tergites lacking; laterotergites not present on terga 2–4 [1].

They are easily distinguished from all other wingless genera of Doryctinae by the high insertion of the metasoma and the complete absence of wings which are not indicated, even as small scales or wingpads [1]. Like the other Leptospathiini is distinguished from all other Doryctinae by the presence of distinct and usually wide propodeal bridge (heavy sclerites between coxal and metasomal foramens) [2].
It has a petiolate metasoma that is inserted high on the propodeum and far from the hind coxae, similar to members of Evaniodes but differ by a distinct dorsope, and the hind coxae without basal tubercle [1].
The reduction of ocelli and its extremely tiny size are reminiscent of Psenobolus, Ecphylopsis and Ecphylus. However, of these genera only Psenobolus has a petiolate metasoma. Brachypterous Psenobolus are highly modified, with swollen femora, but the mesosoma is inserted directly above the hind coxae as is the norm in Doryctinae [1].
It is distinguished from Leptospathius, Stephanospathius and Schlettereriella by the absence of ocelli, and the second tergum without any furrows [2].
It is distinguished from Australospathius by the propodeal tubercles absent, the first flagellar segment subequal or slightly shorter than second segment, the propodeal bridge wide, the acrosternum of first tergum short (0.4 times as long as tergum, and the vertex and frons smooth. [2].
