Head. Antennae 61–82 flagellomeres. Scape less than two times longer than maximally wide. Apical lobe of scape absent, margin of scape and pedicel without dense cluster of setae. Scape shorter than first flagellomere. First flagellar segment equal to or shorter than second, surface smooth dorsally, more or less sculptured ventrally, flagellomere often compressed and curved in lateral view. Maxillary palpi six-segmented, labial palpi four-segmented, third labial palp segment as long as or longer than second. Malar suture absent. Eyes glabrous. Frons excavated (concave, sometimes weakly), with lateral protuberances, raised ridge between antennae absent. Occipital carina present, at least laterally, not meeting hypostomal carina (ending close only). Ocelar triangle with base shorter than its sides. Vertex not striate or striate, smooth.
Mesosoma. Propleuron only smoothly rounded. Pronotum dorsally without modifications (or convex lobe). Mesoscutum with a sharply raised face anteriorly, at right angle with pronotum, surface of median and lateral lobes smooth and shining (median lobe often with a longitudinal groove anteriorly). Notauli complete or at least partly present (smooth or sculptured). Prescutellar depression (scutellar sulcus) long and narrow or of medium length. Scutellum flat. Prepectal carina present. Sternaulus (precoxal sulcus) present, long (more than 2/3 length of mesopleuron), at least partly sculptured (even only anteriorly; sometimes fully). Metanotum without any protuberances or spines. Metapleuron glabrous or with a very sparse/rare discret pubescence. Propodeal bridge between abdominal and coxal foramina present, narrow. Propodeum not convex, sloping from base to apex or horizontal, completely or partly (micro)sculptured. Propodeal carinated areas completely absent. Propodeum without lateral tubercles, without median process.
Wings. Wings present. Radial (marginal) cell of fore wing distally closed. Second radiomedial vein (r-m) of fore wing present, largely tubular, with two bullae. First radiomedial vein (2-SR) of fore wing present, leading the first and second submarginal cells of fore wing separated. Recurrent vein (m-cu) of fore wing interstitial or antefurcal (arising basad or directly in line with 2RS, (RS+M)b present then second submarginal cell petiolate horizontally). Nervellus (cu-a) of fore wing present, postfurcal or interstitial, inclivous. Parallel vein (CU1a) relative to cubital vein (2-CU1) of fore wing not interstitial, arising behind middle of distal vein of brachial cell (short space between the curved part and the level of 2–1A vein), brachial (1st subdiscal) cell of fore wing distally closed. Fore wing of male without sclerotized enlargement, including veins 1-m and 1-SR+m. Hind wing with four to eight distal hamuli. Hind wing without transverse vein (r) of radial cell. Hind wing with the recurrent vein (m-cu), recurrent vein (m-cu) not curved towards apex of wing. Hind wing with the nervellus (cu-a) vein. Hind wing male without a stigma-like enlargement. Hind wing with a small or medium sized submedial (subbasal) cell, the first abscissa of M + CU 0.2–1.0 times as long as second abscissa (1-M). Medial (basal) cell of hind wing closed. Fore wing banded, or more or less infuscate (sometimes with pale spots inside) (often strongly infuscate).
Legs. Fore femur without dorsal protuberances. Fore tibial spines present, usually few and forming a single row. Subapical teeth on fore and middle femora ventrally absent. Mid femora without dorsal protuberances. Hind coxa dorsally without teeth. Hind tibia without comb of dense flat setae at inner apex. Hind femora without dorsal protuberances, not swollen (at least 3x longer than wide). Dorsal spines of hind tibia absent. Hind femur without teeth on ventral side. Basoventral tooth of hind coxa absent. Hind basitarsus 1–1.1 times as long as tarsi 2–5 combined.
Metasoma. Petiole more 2.5 times its apical width, without basolateral process (pointed wing-like, spine-like projections) near base, apical width less than or equal to 1.5 times (or subequal to) basal width. Petiole without median carinae. Dorsope of first metasomal tergite absent or indistinct. Acrosternite of first metasomal tergite long, 0.3–0.5 as long as tergite and fused with its ventral margin anteriorly, petiole present. First and second tergites not fused. Laterotergites separated from each other for at least second and third tergites, separated only at second and third tergites. Second tergite without apical lenticulate area. Second tergite basal area enclosed by carinae or grooves present (sometimes shallow grooves), basal area of second tergite connected with second suture, basal area of second tergite posteriorly wide, width of its apical part subequal to or slightly less than basal width (its surface areolate, striate, smooth). Second metasomal suture present, shape of second metasomal suture with more or less distinct lateral angulations. Third tergite medially without any distinct transverse narrow depression. Fifth or sixth metasomal tergites not enlarged, not covering succeeding tergites and entirely smooth. Fourth-sixth metasomal tergites of males smooth (or striate/coriaceous) basaly, simple, submarginal lateral carinae absent.
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) [1].
It is distinguished from Leptospathius by the frons with large lateral protuberances, the base of ocellar triangle less than its lateral sides, the lateral furrows of second metasomal tergum divergent posteriorly and touched second suture, the submedial cell of hind wing small (first abscissa of mediocubital vein 0.2–0.3 times as long as second abscissa), the radial cell of hind wing without transverse vein and the presence in Afrotropical Region only [1].
It differs from Stephanospathius, present in Oriental and Australasian Regions, by the first flagellar segment of antennae distinctly shorter than second segment, the fore femur on inner side without carinae, the hind coxa of female and male without tooth, the sternaulus present, the acrosternum of first tergum short (less than 0.5 times as long as tergum), the recurrent vein antefurcal and the pronope and pronotal carinae usually absent [1].
It differs from Oroceguera and Australospathius by the presence of ocelli, and the second tergum with two more or less distinct furrows [1].
