Plesiopsenobolus
Head not depressed, transverse; ocelli arranged in triangle with base 1.2–1.3 times its sides, or sometimes in almost equilateral triangle; frons with distinct and wide excavation running from lateral ocelli, with a narrow, long longitudinal keel, with distinct lateral protuberances often emarginated dorsally by incomplete longitudinal carina; eyes mostly glabrous; occipital carina coarse, dorsally complete, fusing with hypostomal carina before mandibles; postgenal bridge wide; palpi formula 6-4; scape of antenna wide and long, with fine apical flange but without ventroapical lobe and basal constriction, ventral margin of scape 0.7–0.85 times as long as dorsal margin (lateral view); first flagellar segment subcylindrical, not curved, equal to or slightly longer than second segment; mesosoma not depressed, elongate; neck of prothorax short, strongly or distinctly convex dorsally (lateral view), with short and distinct curved up anterior flange; submedian pronotal carina distinct; mesonotum highly and almost perpendicularly elevated above pronotum, mainly granulate or granulate-coriaceous; median lobe of mesonotum without median longitudinal furrow, anterolateral corner wide and obtuse; notauli complete, deep and wide; scutellar disc slightly convex, slightly shorter than or as long as wide, without distinct lateral carinae; sternaulus shallow, wide or narrow, short, slightly curved or straight, oblique; prepectal carina distinct and complete, reaching lower margin of subalar depression or upper margin or sternaulus; propodeum with areas delineated by distinct carinae, areola large, lateral tubercles usually absent or sometimes low and obtuse; propodeal bridge absent; fore tibia with several long and slender spines arranged in a vertical line; middle tibia with several spines on anterior surface; hind coxa long and wide, with a distinctly rounded baso-ventral angle but without tubercle; fore and middle femora without dorsal protuberances; hind tibia without comb of dense and long setae along its inner distal margin; hind basitarsus 0.5–0.55 times as long as second-fifth segments combined; vein r of fore wing arising slightly before or from middle of pterostigma; marginal cell not shortened; 2RS and r-m present; 1m-cu interstitial or antefurcal; 1cu-a postfurcal; first discal cell petiolate anteriorly; 1M and 1m-cu slightly divergent posteriorly or subparallel; 3CU not interstitial, distinctly curved basally; first subdiscal cell open postero-apically; veins 2cu-a, 1a and 2a absent; hindwing vein RS arising from R far from r-m; marginal cell slightly widened basally, distinctly narrowed towards apex, without vein r; cu-a present; M+CU 0.5–0.7 times as long as vein M; m-cu long, subvertical, slightly curved towards wing apex; hindwing of male without stigma-like enlargement; first tergite petiolate, long or medium size, wide or narrow, slightly convex dorsally; acrosternite 0.7–0.75 times as long as first tergite, prolonged distinctly behind spiracular level; basolateral lobes absent; tergite with a fine semi-circular transverse carina basomedially, carina coarse laterally, with fine and almost complete dorsal carinae; second and third tergites without furrows; second suture fine or indistinct, if present, then complete and slightly sinuate; ovipositor with two almost indistinct subapical nodes, ovipositor sheaths longer than metasoma [1].

This genus is morphologically similar to Psenobolus, Ficobolus and Sabinita. It is distinguished :
- from Psenobolus by its prescutellar depression long, usually with sparse and a few carinae; its scutellar disc subtriangular, its maximum width often equal to or less than its maximum length, 2.0–3.0 times longer than prescutellar sulcus; its notauli usually wide, always complete, not reduced posteriorly and always connected with anterior margin of prescutellar sulcus; its propodeum always with areas and areola delineated by coarse carinae, mainly sculptured; its hind coxa with basoventral corner and by its association with galls on vegetative organs of Ficus species [1].
- from Sabinita by its first metasomal tergite long or rather long and more or less narrow; its acrosternite long (0.7–0.8 times as long as first tergite); the scape of antenna without ventroapical lobe, the length of ventral margin of scape (lateral view) always less than length of its dorsal margin; its vein 1m-cu vein of forewing antefurcal or sometimes almost interstitial, never postfurcal; its propodeum without lateral tubercles, if present, short and subrounded; its median keel of frontal cavity rather slender and more or less pointed dorsally [1].
- from Ficobolus by its first flagellar segment not long, about as long as second segment; its frontal cavity laterally without or with fine and incomplete longitudinal carina; its median lobe of mesosoma always without median longitudinal furrow; its mesopleuron entirely only granulate, without additional oblique furrow; its sternaulus not running to posterior margin of mesopleuron; its metapleural flange long, narrow in lateral and posterior views, and its ovipositor sheaths longer than metasoma [1].
