Ficobolus
The two known species of this genus are associated with species of Ficus. The type species was reared from stem galls of Ficus perforata Linnaeus [1].

Head not depressed, transverse; ocelli arranged in almost equilateral or isosceles triangle with its base larger than its sides; frons with distinct and relatively narrow excavation running from lateral ocelli, with distinct, slender and not pronounced median longitudinal keel in its anterior half, with distinct lateral protuberances emarginated by a sharp longitudinal carina; eyes often with sparse and short setae or almost glabrous; occipital carina complete, fused with hypostomal carina before mandible; palpi formula 6-4; scape wide and short, without apical flange and ventroapical lobe, without basal constriction, ventral margin of scape shorter than dorsal one (lateral view); first flagellar segment long, subcylindrical, slightly curved outwards, distinctly longer than second segment; mesosoma not depressed, short; neck of prothorax short, slightly convex dorsally (lateral view); pronotal carina absent or present; mesonotum high, almost perpendicularly or roundly elevated above pronotum; median lobe of mesonotum with or without distinct median longitudinal furrow, anterolateral corner absent; notauli complete, deep, wide, not joining and reaching posterior margin of mesoscutum separately or sometimes joining at posterior edge of mesoscutum; scutellar disc slightly convex, not transverse, without lateral carinae; sternaulus deep, wide and long, running to posterior margin of mesopleuron, distinctly curved up anteriorly, slightly curved posteriorly; prepectal carina distinct and complete, pronounced ventrally, laterally reaching anterior margin of subalar depression; propodeum with areas delineated by distinct carinae, lateral tubercles absent; propodeal bridge absent; fore tibia with several long and slender spines arranged along its anterior margin in almost vertical line; middle tibia with several spines on anterior surface; hind coxa long and narrow, with distinct basoventral angle but without tubercle; fore and middle femora with small dorsal protuberances; hind femur widened and elongate-oval, but in male strongly widened; hind tibia with area of dense setae on its inner apical quarter; hind basitarsus thickened, 0.5–0.8× as long as second–fifth segments combined; vein r arising from or before middle of pterostigma; marginal cell slightly shortened; RS and r-m present; second submarginal cell long and narrow; m-cu slightly antefurcal; 1cu-a postfurcal; first discal cell petiolate anteriorly; M and m-cu subparallel or slightly convergent towards posterior margin of wing; first subdiscal cell widely open postero-apically, 2cu-a absent; Veins 1a and 2a absent; Hind wing vein RS arising from vein R far from vein r-m; marginal cell slightly widened basally, then more or less distinctly narrowed towards apex, without vein r; cu-a present; M+CU not or slightly shorter than vein 1M; m-cu long, oblique toward apex of wing, slightly evenly curved or straight; male hind wing without stigma-like enlargement; first tergite petiolate, long, narrow and distinctly curved; acrosternite long, 0.6–0.7 times as long as first tergite, ending behind spiracles; dorsope of first tergite small and shallow; basolateral lobes short and wide; tergites in basal 0.15 with a distinct semi-circular, transverse carina; second and third tergites without furrows; second suture complete, straight and considerably shallow or absent; ovipositor nodes indistinct, ovipositor sheaths distinctly shorter than metasoma[1].

It can be distinguished from those of the remaining doryctine genera by having the mesopleuron with an oblique furrow and a distinct frontal cavity laterally margined by a sharp longitudinal carina. It is morphologically similar to species of Psenobolus, Plesiopsenobolus and Sabinita, but can be distinguished :
- 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); its 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 fore wing antefurcal or sometimes almost interstitial, never postfurcal; its propodeum without lateral tubercles, if present, short and subrounded, and its median keel of frontal cavity rather slender and more or less pointed dorsally [1].
- from Plesiopsenobolus by its first flagellar segment long, distinctly longer than second segment; its frontal cavity laterally marginated almost completely by sharp longitudinal carina; its median lobe of mesonotum often with distinct median longitudinal furrow; its mesopleuron entirely coarsely rugose with granulation, always with additional and at least incomplete oblique furrow; its sternaulus running to posterior margin of mesopleuron; its metapleural flange short, wide in lateral and posterior views, and its ovipositor sheaths distinctly shorter than metasoma [1].
- from Psenobolus by its prescutellar depression long, usually with sparse to 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].
