Cretadystaxiini Legalov, 2025, trib. n.

Tribe Cretadystaxiini trib. n. https://zoobank.org/ urn:lsid:zoobank.org:act: A38CFDCF-8805-46B3-92E1-A83DE1BCD19B Type genus: Cretadystaxia gen. nov. Diagnosis. Body dorsally finely punctate; eyes finely facetted; maxillary palpomeres third and fourth equal in length; antennae eleven-segmented, weakly serrate; antennomeres elongated triangular; pronotum with weak lateral carinae; pronotal disc without impressions; base of pronotum weakly bisinuate; lateral margins of elytra serrate; elytral striae present; metepisternum broad, narrowed posteriorly; first and second ventrites with suture visible only laterally; metacoxae notched on anterior margin; femora without disto-ventral grooves for tibiae; metatibia with spur and dense brush of setae on apical third of inner margin; tarsi five-segmented; tarsomere fourth deeply bilobed; tarsal claws bifid. Comparison. The new tribe is similar to the tribe Dystaxiini, but differs in the 11-segmented antennae, striate elytra, the weakly bisinuate base of the pronotum and the flattened body. It differs from the tribe Schizopodini in the serrate elongate triangular antennomeres, striate elytra, pronotal disc without impressions and body sculpture of fine punctures, and from the tribe Electrapatini in the broad metepisternum narrowed posteriorly, striate elytra, metacoxae notched at anterior margin, first and second ventrites with suture visible only laterally, maxillary palpomere fourth equal in length to palpomere third, femora without disto-ventral grooves for tibiae.
