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 ardonius Brito & Azevedo , sp. nov. ( Figs 9 , 40 , 71 , 133–135 ) Description. Male. Body length 3.22 mm . Color: body castaneous. Head ( Fig. 9 ). Mandible with two distal teeth. Median clypeal lobe trapezoidal, with one angulate tooth; median clypeal carina high in profile, complete or nearly so, straight in profile or nearly so. Frons weakly coriaceous and punctures small. Vertex crest weakly concave. Pronotal disc coriaceous; anterior margin coarse. Metasoma ( Fig. 40 ). Tergal process with lateral, shallow, circular and small depression, with large, very low and dorsad tubercle placed on center of depression, pit large, with short and sparse tuft of setae. Posterior hypopygeal margin median straight with angled corners ( Fig. 71 ). Genitalia ( Figs 133–135 ): paramere with dorsal margin entirely wide; apical margin truncate. Aedeagal ventral ramus shorter than dorsal body, entirely wide, cross section laminar; surface vertical; inner margin strongly sinuous; outer margin slightly sinuous; apex long, slightly crenulate, parallel; additional inner ramus long; basal stub long and narrow. Aedeagal dorsal body with two pairs of apical lobes, outer lobe long, vertical and very narrow, with apical margin acute and ventrad; inner pair stout, membranous and setose. Apodeme not extending beyond genital ring. Variation. Metasoma light castaneous. Remarks. This species is easily recognized by having two spines in the ventral margin of the apical lobes of the aedeagal dorsal body with apical spine shorter than distal one, the aedeagal ventral ramus vertical and wide in the median portion with wavy apex. This species is similar to D. urazius sp. nov. by having spine in the ventral margin of apical lobes of the aedeagal dorsal body and the aedeagal ventral ramus entirely wide with the inner margin sinuous. However, this species has the dorsal margin of the paramere sinuous, the apex of the basal bar not projected forward, and the apical margin of the aedeagal dorsal body wavy, whereas D. urazius sp. nov. has the dorsal margin of the paramere not sinuous, the apex of the basal bar projected forward and the apical margin of the aedeagal ventral ramus not wavy.
