Unknown.
Head. Head subcubical, 1.5 times wider than long medially. Scapus rather short and wide, with strong basal constriction and with small semi-oval apical lobe and preapical keel along inner side; 1.7 times longer than maximum width. First flagellar segment simple, longer than 2nd segment. Palpi rather long; maxillary palpi 6-segmented, labial palpi 4-segmented; 3rd segment of labial palp not shortened. Malar suture very shallow. Hypoclypeal depression rather small and round. Clypeus with double lower carinae. Clypeal suture distinct, shallow dorsally. Face with 2 distinct submedian oval depression above clypeal suture. Eyes glabrous. Frons weakly concave and without median keel, with lateral keels along border of eyes. Ocelli in equilateral triangle. Occipital carina present, complete, fused with hypostomal carina. Postgenal bridge distinct.
Mesosoma. Neck of promesosoma short, simple dorsally. Pronotal keel distinct, near mesoscutum. Propleural lobe distinct and wide. Mesonotum highly and almost perpendicularly raised above promesosoma. Median lobe of mesoscutum with short anterolateral angulations (corners). Notauli deep and smooth. Prescutellar depression rather long and smooth, with sparse striae. Scuto-scutellar suture distinct. Scutellum weakly convex, without lateral carinae, its length 1.3 times maximum width. Postscutellum with short median keel. Subalar depression rather deep and narrow. Mesopleural pit very shallow and elongate. Sternauli deep, rather long, straight, and smooth. Prepectal carina distinct and complete. Prepectus with 2 lateral longitudinal parallel carinae. Metapleural flange rather short, narrow and pointed apically. Propodeum with marginate areas; lateral tubercles and propodeal bridge absent. Propodeal spiracles small and round.
Wings. Pterostigma of fore wing wide; vein r arising almost from middle of pterostigma. Marginal cell not shortened. Vein 2RS largely unsclerotized, indistinct, postfurcal. Discoidal cell petiolate. Vein 2CUb distinctly curved basally. First subdiscal cell open apically. Vein M + CU not curved towards vein 1A. Hind wing with 3 hamuli on vein R1. Vein cu-a present. Subbasal cell short. Vein M + CU 0.7 times length of 1M. Vein m-cu present, antefurcal, almost perpendicular to medial vein, unsclerotized. Basal cell narrow, 0.33 times as long as hind wing. Hind wing vein RS arising from vein R1. Marginal cell weakly narrowed apically, without additional transverse vein. Vein C + SC + R 1.4 times length of SC + R.
Legs. All tibiae slender. Fore tibia with numerous small and dispersed spines. Hind tibia with 4 spines on outer side and with row of dense white setae on inner distal edge. Hind coxa without basoventral tooth. Femora without anterodorsal protuberances. Hind femur 3 times as long as wide. Hind tibial spurs rather short and slender, sparsely setose, inner spur almost 0.25 times as long as hind basitarsus. Hind basitarsus 0.4 times as long as 2nd-5th segments combined.
Metasoma. First tergite not petiolate, narrow. Acrosternite 0.25 times as long as 1st tergite, its apical margin distinctly anterior to spiracles. Dorsope of 1st tergite distinct; basolateral lobes absent; spiracular tubercles indistinct, spiracles on basal third of tergite; dorsal carinae present and complete. Second suture distinct, very weakly curved laterally. Second tergite with very small semi-oval mediobasal area. 3rd tergite with transverse fine furrow in basal third. Second to 5th tergites with separate laterotergites. Hypopygium small, with very short and pointed process medioposteriorly. Ovipositor shorter than metasoma [1].

Transformations of the scape are known in several doryctine genera (e.g. Syngaster Brulle, Pseudodoryctes Szepligeti, Siragra Cameron, Binarea Brulle, Pseudorhoptrocentrus Granger, Jarra Marsh & Austin) as they are among the Braconinae (Quicke 1987). However, the new genus Synspilus gen. nov. is the first doryctine in which the scape not only has an apical lobe demarcated by a preapical, transverse carina, but also has a strong basal constriction as in the Atanycolus Forster group of genera in the Braconinae (Quicke 1987) which are all parasitoids of bark-boring or subcortical beetles in dead standing or fallen wood. In addition, this genus is included in a group with an apically open 1st subdiscal cell and a strongly reduced vein 2RS (tribe Heterospilini Belokobylskij 1992) [1].
