Review of Dissomphalus Ashmead (Hymenoptera, Bethylidae) from Panama, with key to the Central American species Author Azevedo, Celso O. text Zootaxa 2017 2017-10-13 4335 1 1 72 journal article 31852 10.11646/zootaxa.4335.1.1 f2ad3cb1-0bad-4be1-9e36-2170a6a08aaf 1175-5326 1010014 3429592D-23A8-4EBF-8412-BD57B3BC4314 Dissomphalus iozus Brito & Azevedo , sp. nov. ( Figs 5 , 36 , 67 , 105–106 ) Description. Male. Body length 3.13 mm . Color: body castaneous. Head ( Fig. 5 ). Mandible with four distal teeth. Median clypeal lobe ill-defined, with one angulate tooth; median clypeal carina low in profile, incomplete apically, straight in profile or nearly so. Frons weakly coriaceous and punctures small. Vertex crest straight. Pronotal disc weakly coriaceous; anterior margin ecarinate. Metasoma ( Fig. 36 ). Tergal process absent. Posterior hypopygeal margin straight or nearly so ( Fig. 67 ). Genitalia ( Figs 105–106 ): paramere with dorsal margin entirely wide; apical margin rounded. Aedeagal ventral ramus shorter than dorsal body, wide, progressively narrowing apicad; cross section laminar; surface horizontal; inner margin sinuous; outer margin slightly sinuous; apex short, simple, parallel; additional inner ramus absent; basal stub absent. Aedeagal dorsal body with two pairs of apical lobes; outer lobe long, horizontal and wide, with apical margin rounded and dorsad; inner pair stout, membranous and setose. Apodeme extending beyond genital ring. Remarks. This species is easily recognized by having the genitalia robust, the lobes of the aedeagal dorsal body with the apical region more expanded, rounded, laminar and the aedeagal ventral ramus very wide. This species is similar to D. abarus sp. nov. by having the dorsal margin of the paramere rounded, the outer lobes of the aedeagal dorsal body long and the aedeagal ventral ramus wide. However, this species has the apex of the apical lobes of the aedeagal dorsal body rounded and laminar, the apex of the aedeagal ventral ramus without projections, whereas D. abarus sp. nov. has the apex of the aedeagal ventral ramus not rounded nor laminar and the apex of the aedeagal ventral ramus with two small rounded projections.
