Included species: Anisotermes xiai Zhao, Eggleton & Ren 2019 (type species) and A. bourguignoni Jouault, Engel, Huang & Nel sp. nov.

Emended diagnosis: Head approximately rounded; ocelli absent; fontanelle absent; Y-shaped ecdysial line absent; mandible not exceeding labrum, with la and ra conspicuously longer than LM1 and RM1; antenna moniliform, with about 25 antennomeres, terminal eight antennomeres tapered; compound eyes hemispheric, lying at head midlength; pronotum definitely saddle-shaped, slightly wider than head in dorsal view; lateral margin weakly upcurved; procoxal carina present; additional tibial spines present on all legs; tibial spur formula 3-4-4; tarsi wholly pentamerous; arolium variable (absent in A. xiai but present in A. bourguignoni ); wings membranous, densely reticulate; forewing scale large, overlapping hindwing base, basal suture convex, veins Sc, RA, RP and M more heavily pigmented than CuA. Forewing: all major veins originate within scale; Sc simple or double; RP with five to six main branches, terminating on costal margin anterior to wing apex; radial field of moderate width, parallel to costal margin; M running about midway between RP and CuA, terminating on posterior margin; medial field relatively narrow; CuA branched, terminating about same distance with Rs to wing apex; PCu (claval suture) arched, meeting basal suture on posterior margin. Hindwing without basal suture, large anal lobe present; M first inferior branch fading away, terminating in center of hindwing; cerci short, trimerous or tetramerous (with additional indented rings); abdominal styli absent in female but present in male.
