Descriptions of a new subgenus and two new species of Atrichobrunettia Satchell (Diptera, Psychodidae) from the Neotropical region Author Bravo, Freddy text Zootaxa 2007 1590 61 68 journal article 10.5281/zenodo.178550 16dbeb36-32c8-4adc-bf6c-3ba7be08ec1f 1175-5326 178550 Atrichobrunettia ( Pachybrunettia ) trilobata Bravo , sp. nov. ( Figs. 4–12 ) Type material. BRAZIL , Amazonas, Silvis (Saraça), mata virgem, holotype male, 29.V.1997 ( INPA ); 2 paratypes male, same locality, perturbed area, 30.VI.1997 , without collector’s name (1 paratype INPA , 1 paratype MZUEFS). Etymology. trilobata refers to the three apical lobes of the sternite 10. FIGURES 4–12. Atrichobrunettia ( Pachybrunettia ) bilobata Bravo , sp. nov. Male, holotype (4, 8–12), paratype (5–7). 4. Head. 5. Antenna: scape and pedicel. 6. Antenna, flagelomere 1. 7. Antenna, flagelomeres 3–4. 8. Palpomeres 1–2. 9. Wing. 10. Male terminalia, lateral. 11. Male terminalia, ventral, epandrium and sternite 10. 12. Male terminalia, dorsal. ae= aedeagus; ae. ap.= aedeagal apodem; gx. ap.= gonocoxal apodeme; ns= narrow sclerites, well sclerotized, link the base of parameres to the apex of the gonocoxal apodeme; par= paramere; php= post-hypandrial plate; S10= sternite 10. Distance AB= distance between the hypandrium and the gonocoxal apodeme. Diagnosis. Frontal scar patch divided medially ( Fig. 4 ). Radial fork distal to medial fork ( Fig. 9 ). The distance AB between the hypandrium and the gonocoxal apodeme is 2.0x the length of the paramere ( Fig. 12 ). Apex of sternite 10 with lateral lobes ( Fig. 11 ). Description. Male. Frontal scar patch divided medially ( Fig. 4 ); scape 1.5x the length of the pedicel ( Fig. 5 ); 1st flagellomere ( Fig. 6 ) less rounded than the following flagellomeres ( Fig. 7 ); ascoids missing. Maxillary palpi incomplete, only the 1st and 2nd being present ( Fig. 8 ). Wing with short Sc; radial fork apical to medial fork ( Fig. 9 ). Male terminalia ( Figs. 10, 11, 12 ): the distance AB between the hypandrium and the gonocoxal apodeme is 2.0x the length of the paramere; cerci with apical tenacula many of them lost in the specimens; apex of tenacula broken; epandrium sub-rectangular with small foramen; apex of sternite 10 with two lateral lobes. Comments. The two paratypes of A. trilobata sp. nov. were previously included in the species A. minuta by Bravo (2006) . This confusion was originated because these two paratypes , from the Amazonas State, are very clear and some characters were erroneously interpreted. However, the discovery of a new and better preserved specimen from the same locality in Amazonas State permitted a more detailed analysis. In the present paper, the three specimens from Amazonas State are included in a new species of Atrichobrunettia , A. trilobata . The wing venation and the male terminalia of A. minuta and A. trilobata are very similar; however, 3 differences stand out between these 2 species: 1) the frontal scar patch is undivided in A. minuta and divided in A. trilobata sp. nov. ; 2) the apex of sternite 10 of A. minuta do not have lateral lobes, while A. trilobata sp. nov. has two big lateral lobes; 3) the foramen of epandrium of A. minuta is larger than that of A. trilobata sp. nov. Distribution. Brazil , Amazonas (Silves).
