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 ibocius Brito & Azevedo sp. nov. ( Figs 7 , 38 , 69 , 127–128 ) Description. Male. Body length 2.24 mm . Color: body dark castaneous. Head ( Fig. 7 ). Mandible with two distal teeth. Median clypeal lobe ill-defined, with one angulate very short tooth; median clypeal carina low in profile, incomplete apically, angled in profile. Frons weakly coriaceous and punctures small. Vertex crest weakly concave. Pronotal disc coriaceous; anterior margin carinate. Metasoma ( Fig. 38 ). Tergal process with shallow, subcircular and large depression, with very small and very low dorsad tubercle placed on inner area of depression, pit very small with short tuft of setae. Posterior hypopygeal margin weakly concave ( Fig. 69 ). Genitalia ( Figs 127–128 ): paramere with dorsal margin entirely wide; apical margin truncate. Aedeagal ventral ramus shorter than dorsal body, wide, abruptly narrowing apicad; cross section laminar; surface subvertical; inner margin sinuous; outer margin sinuous; apex long, crenulate, curved outward; 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 crenulate and laterad; inner pair stout, membranous and setose. Apodeme not extending beyond genital ring. Variations. Body length between 1.79 (min.) mm and 2.60 (max.) mm. Remarks. This species is similar to D. asitius sp. nov. by having the aedeagal ventral ramus with toothed apex and the paramere with crenulate apex. However, it species has the apical lobes of the aedeagal dorsal body long, with laterad apex and the paramere with the dorsal margin sinuous, whereas D. asitius sp. nov. has the apical lobes of the aedeagal dorsal body shorter with dorsad apex and the paramere with the dorsal margin almost straight.
