This new tribe is characterized by the presence of the characters listed above, which are typical to the Ampulicinae. It differs from all other tribes by the long crescent mandibles, compara- tively small eyes, and the occipital carina forming a complete circle (in the studied specimens of Apodolichurini trib. nov. and Cretampulicini trib. nov. the occipital carina is visible only dorsally, and it is unknown for Trigampulex gen. nov. because of the absence of the holotype head). Furthermore, Mendampulicini trib. nov. dif- fers from Dolichurini by the separated hindcoxae and the abdominal petiole inserted between and on the same level as the hindcoxae; from Ampulicini by the clypeus without a medial carina, unpaired frontal prominence, open mandibular sockets, hypognathous mandi- bles, considerably elongate maxillary and labial palpi, thin and unmodified tarsomeres (without ventral pubescence on the penulti- mate tarsomeres and with an arolium on the apical tarsomeres), not Y-shaped metasternum, and by the fore- and hindwing mediae diverging beyond cu-a; from Apodolichurini trib. nov. by the consid- erably flattened head, pronotal collar without expressed lateral ridges, long scutum, and by the dentate tarsal claws; from Cretampulicini trib. nov. by the clypeus lacking a medial carina, unpaired fron
