Distribution.

PERU. Ancash, Ayacucho , Cajamarca , Huan-cavellica, Junín, La Libertad and Pasco (Fig. 28 View Figure 28 ).

Diagnosis.

Ayacucho can be differentiated from all other Metasarcidae genera by its short leg IV (femur IV length/DS length <1.5). Most of its species can be distinguished from other genera by having, alpha-type DSS; a femur of pedipalpus slightly flattened and males without a proapical spine (present in all other genera), an ocularium high and rounded and a DS densely granulated.

Redescription.

Alpha-type DSS (Figs 2C, F, G View Figure 2 ), except for A. spielbergi sp. nov. (gamma-type; Fig. 2A View Figure 2 ) type. Femur of pedipalpus slightly flattened (except for A. spielbergi sp. nov.) and generally armed in ventral surface; males without a proapical spine; females armed with a proapical spine (absent in some species of " Ayachuco silvae clade", A. spielbergi sp. nov. and A. pasolinii sp. nov.) Ocularium high and rounded in most species (Fig. 2A-C View Figure 2 ); low, medially depressed ( A. pasolinii sp. nov., A. spielbergi sp. nov., A. spiniger comb. nov., e.g. Figs 2E View Figure 2 , 3A View Figure 3 ). Ocularium with two low tubercles or high spines (most species). Areas of dorsal scutum moderately ( A. pasolinii sp. nov., A. spielbergi sp. nov., A. weyrauchi comb. nov., e.g. Figs 2E View Figure 2 , 3A View Figure 3 ) to densely tuberculate (most species, e.g. Fig. 2B, C View Figure 2 ). Area I undivided. Area III unarmed ( A. silvae sp. nov., A. uniseriatus comb. nov., A. weyrauchi comb. nov., e.g. Fig. 3H View Figure 3 ), armed with two tubercles (most species, e.g. Fig. 2C View Figure 2 ), or armed with two high spines ( A. pasolinii sp. nov., A. spielbergi sp. nov., e.g. Fig. 2E View Figure 2 ). Posterior margin of DS small tuberculate (Fig. 2C View Figure 2 ), or armed with a pair of high tubercles (Fig. 3B View Figure 3 ) or a row of high tubercles. Coda elongate, with constriction in most species (Fig. 3D-F View Figure 3 ). Coxa III with two apophyses (execpt in A. pomacocha sp. nov. and A. spielbergi sp. nov.). Coxa IV reaching area III or sulcus IV (Fig. 3D-F View Figure 3 ). Coxa IV armed with an acute long tubercle in most species (Fig. 3H View Figure 3 ), or unarmed ( A. pasolinii sp. nov., A. pomacocha sp. nov., A. silvae sp. nov., A. titschacki , e.g. Fig. 3G View Figure 3 ). Femur IV shorter than dorsal scutum length in most species or longer ( A. tapacocha nom. nov., A. spiniger comb. nov.). Less than 10 MS C. Penis stylus thin. Penis VP thin (Figs 12 View Figure 12 , 15 View Figure 15 ).
