No genetic sequence data are available for the group.  Matantas koghisiana(Heraty) comb. n. is the only species described for the genus.  Diagnosis. Separated from  Orasemaby the combination of smooth lateral areas on the propodeal disc in combination with a rugose-areolate or reticulate median channel, smooth face, and labrum with 6-8 digits. Distinguished from other Old World genera by the head subtriangular in frontal view; face smooth and relatively flattened, scrobal depression evenly impressed and lacking parallel channels or dorsal foveae; dorsal occipital margin abrupt and rounded, at most with a weak dorsal carina; funicle 7-segmented; labrum with 6-8 digits; mesonotum appearing bare, at most with minute setae; mesoscutal lateral lobes and frenum smooth; transscutal articulation complete and relatively straight; propodeal disc smooth with a broad sculptured median channel; prepectus foveate and tightly articulated with pronotum ventrally; fore wing with basal area and specular area bare, wing disc setae relatively long and dense; postmarginal vein much longer than stigmal vein and reaching about half distance to wing apex; petiole base truncate with strong basal flange; antecostal sulcus present and smooth; first valvula of ovipositor with 3 or 4 lateral teeth. Male scape lacking ventral pores.  Host association. Unknown.  Distribution. One species described. New Caledonia (another undescribed species from Vanuatu, BPBM: UCRCENT00422296).
