Treatment

Atrichobrunettia (Pachybrunettia) trilobata Bravo View in CoL , sp. nov.

( Figs. 4–12 View FIGURES 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.

Diagnosis. Frontal scar patch divided medially ( Fig. 4 View FIGURES 4 – 12 ). Radial fork distal to medial fork ( Fig. 9 View FIGURES 4 – 12 ). The distance AB between the hypandrium and the gonocoxal apodeme is 2.0x the length of the paramere ( Fig. 12 View FIGURES 4 – 12 ). Apex of sternite 10 with lateral lobes ( Fig. 11 View FIGURES 4 – 12 ).

Description. Male. Frontal scar patch divided medially ( Fig. 4 View FIGURES 4 – 12 ); scape 1.5x the length of the pedicel ( Fig. 5 View FIGURES 4 – 12 ); 1st flagellomere ( Fig. 6 View FIGURES 4 – 12 ) less rounded than the following flagellomeres ( Fig. 7 View FIGURES 4 – 12 ); ascoids missing. Maxillary palpi incomplete, only the 1st and 2nd being present ( Fig. 8 View FIGURES 4 – 12 ). Wing with short Sc; radial fork apical to medial fork ( Fig. 9 View FIGURES 4 – 12 ). Male terminalia ( Figs. 10, 11, 12 View FIGURES 4 – 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.
