GENUS Caudibeccus gen. n.

Type species: Colpoptera carlota Myers 1928 , here designated.

Diagnosis: Metope enlarged before the clypeus, with only median carina running through clypeus. Coryphe transverse, with keel-shaped lateral margins, anterior margin straight, posterior margin concave. Pronotum narrow, with acutely angulate anterior margin, posterior margin concave. Scutellum long, with strong median carina and sometimes with sublateral carinae. Fore wing with wide hypocostal plate. Radius and median bifurcate, cubitus anterior simple or bifurcate (R 2 M 2 CuA 1-2); longitudinal veins with numerous branches distally. Hind tibia with single lateral tooth. Metatarsomere I with 5-6 intermediate socle setae.

Male ( Fig. 63-69 ). Anal tube elongate, strongly convex. Pygofer with convex hind margin. Each dorsolateral phallobase lobe with a bifurcate process. Aedeagus with a pair of long ventral hooks. Stylus with rounded caudo-dorsal angle. Capitulum of the style rudimentary, with only lateral tooth in shape of quadrate plate.

Female. Anal tube long and narrow, narrowing

to apex (in dorsal view) and curved (in lateral view). Anal column narrow and long. Gonoplacs convex, more or less triangular, strongly narrowing apically, fused medially almost along entire length. Posterior connective lamina of gonapophyses IX more or less horseshoe-shaped. Proximal part of the lamina short. Distal parts of the lamina almost parallel to each other. Median field of the lamina in shape of a pair of large lobes proximally. Lateral fields of the lamina flat. Gonospiculum bridge in shape of broad tube, fused with proximal part of posterior connective lamina. Gonocoxa VIII with straight hind margin. Endogonocoxal process narrow and pointed, flattened laterally, with comb of setae on dorsal mar-

lamina of gonapophyse VIII, lateral view. lamina of gonapophysis VIII narrow, flattened laterally, without teeth, entirely covered with setae.

Etymology: The generic name is derived from the Latin words - cauda (tail) and beccus (beak), referring to the unusual long and narrow ovipositor. The gender is masculine.

Composition: In addition to the type species C. carlota , Colpoptera punctata Metcalf, 1954 , C. meleagris Fennah, 1955 , C. lucaris Fennah, 1955 and Caudibeccus emeljanovi sp. n. also belong to the genus.

Distribution: Cuba, South Bimini Island, Bahama Islands, and Dominica.

Comparison: Similar to Colpoptera Burmeister externally and in the structure of male genitalia, but distinguished by the narrow and elongated parts of the ovipositor which probably represents a different manner of oviposition - the elongated and fused gonoplacs are probably used as a directing case for the narrow and pointed endogonocoxal processes and anterior connective laminae in oviposition ( Gnezdilov 2003b). The lateral margins of the coryphe are keel-shaped in Caudibeccus and not in Colpoptera examined to date; however, all Colpoptera species have not yet been examined for comparison.
