Peckia (Squamatodes) ingens ( Walker, 1849) 

( Figs 1–2 View Figure , 105–110 View Figure )

Description of female terminalia. Posterior margin of T5 elliptical, brown, with golden microtrichosity dorsally and silver microtrichosity laterally ( Figs 108–110 View Figure ). T6 undivided, well developed, bright orange, with golden microtrichosity restricted to anterior margin, covered with setulae and with a row of robust setae near posterior margin. Spiracles 6 and 7 located on T6. T8 absent ( Figs 105, 108 View Figure ). Epiproct represented by some long and stout setae on membrane, close to cerci. Cercus covered with setae, with short setae along posterior margin. Hypoproct triangular, with long setae ( Fig. 106 View Figure ). ST6 reduced, square, with setae near posterior margin. ST7 reduced, square, with lateral and posterior margins membranous and one pair of setae on terminal portion of sclerotized region. ST8 U-shaped, without setae ( Fig. 105 View Figure ). Spermathecae rounded, with tiny rounded furrows ( Fig. 107 View Figure ).

Remarks. The female terminalia of P. (S.) ingens  are similar to those of P. (S.) trivittata  in having T6 bright orange, undivided, well developed and projected posteriorly; spiracle 6 located on T6; ST6, ST7 and ST8 reduced; and spermathecae with tiny furrows ( Figs 105, 107–108 View Figure , 111, 113–114 View Figure ). Peckia (S.) ingens  differs from P. (S.) trivittata  by the golden microtrichosity on the abdomen, T6 with golden microtrichosity along anterior margin and ST6 square ( Figs 105, 109–110 View Figure , 111, 115–116 View Figure ). In P. (S.) trivittata  the abdomen has gray microtrichosity, T6 has silver microtrichosity on the anterior margin, and ST6 is rectangular. This species is frequently collected in forests of the Brazilian Amazon using traps baited with dead animals. The above record from Acre is a new state record.
