Ferricixius davidi Hoch & Ferreira, 2012 View in CoL

( Figs 1D View FIGURE 1 ; 12 D View FIGURE 12 ; 13A–E View FIGURE 13 ; 14A–D View FIGURE 14 ; 15A–C View FIGURE 15 ; 16A–C View FIGURE 16 ; 17A–B View FIGURE 17 )

Type material. Holotype: Male, Brazil, Minas Gerais. Itabirito municipality, MP-008 cave, 20.x.2011, (Oliveira, M.P.), ES, ( ISLA 1768).

Material examined. 2 ♀♀ ( Figs. 13 View FIGURE 13 , 14 View FIGURE 14 , 15 View FIGURE 15 ) and 1 ♁, same data as holotype except for ( ISLA 100992) .

Coloration (preserved specimen): Pale yellow (89) contrasting with some areas which are light yellow (86), tegmina hyaline with dark yellowish white (92) regions.

Body length. Female (examined): 2.8–3.2 mm (n =2).

Head. Vertex ( Fig. 13A View FIGURE 13 ): Apical compartment wider than medially long; caudal border of vertex irregular; subapical carina elongated medially; apical transverse carina elongated medially and evanescent laterally. Frons: In lateral view ( Fig. 13B View FIGURE 13 ) semicircular, fully curved from base of vertex to frontclypeus suture. Compound eyes and ocelli ( Figs 13B; 13b View FIGURE 13 1 View FIGURE 1 ; 13D View FIGURE 13 ): Compound eyes vestigial (an extremely reduced, red spot can be observed in living specimens), lateral ocelli vestigial. Antennae ( Figs 13a View FIGURE 13 1 View FIGURE 1 ; 13A–B View FIGURE 13 ): Short scape, globular pedicel with evident sensory plates; pedicel with flagellum and arista; base of arista with two setae apically.

Thorax. Pronotum ( Figs 13A–B View FIGURE 13 ). Mesonotum ( Figs 13A–B View FIGURE 13 ). Tegmina (forewings) ( Fig. 13C View FIGURE 13 ): Length (0.867), very reduced; vein ScP+ R, MP present, CuA, CuP, and Pcu present, tegmina with crossveins distally between ScP+ R, MP, and CuP. Thoracal sclerite at base of forewing ( Fig. 13D View FIGURE 13 ). Hind legs ( Fig. 13E View FIGURE 13 ): Hind tibia with 4 lateral spines and 6 apical teeth; first tarsomere with 4 apical teeth and second tarsomere with 2 apical teeth.

Female genitalia ( Figs 15A–C View FIGURE 15 ). Segment X short; curved dorsally and flattened ventrally. The segment IX as in the diagnosis of the genus. Ovipositor long and arc-shaped, not surpassing segment X; Gonocoxa VIII exhibits a deep groove with thin elongated lines side by side.
