Diagnosis. The males of Architis helveola   share with those of A. tenuipes   the VTA which is articulated with the apex of the pedipalpal tibia ( Figs 9A, B View FIGURES 9 , 12B, C View FIGURES 12 ), but differ by the small vRTA which is not fused to the VTA ( Figs 12B, C View FIGURES 12 ). Females can be distinguished from all other Architis   by the medially projected lateral lobes of the epigynum which cover the anterior half of the median field like a pair of keels ( Fig. 12D View FIGURES 12 ) and the non-encapsulated CD which are shorter than the spermathecae ( Fig. 12E View FIGURES 12 ).

Description

Male ( based on lectotype from São Paulo de Olivença, Brazil)  

Body and legs homogeneously cream-coloured. Anterior eye row procurved, eyes of similar size, laterals projecting ventrally. Posterior eyes of similar size, slightly larger than anterior eyes. Femur I with nine pairs of ventral thin spines. Tibia I with five pairs of ventral spines. Tibia I with long and curved dorsal and lateral tri- chobothria. Total length 8.0. Carapace 2.9 long, 2.4 wide. Tibia I length 5.8, II 5.5, III 3.3, IV 3.6. Opisthosoma 5.1 long, 1.1 wide. The embolus apex is wide, flattened and notched ( Fig. 12B View FIGURES 12 ).

Female (based on IBSP 45232 from Una, Brazil)

Carapace wide and flattened ( Fig. 12A View FIGURES 12 ), orange, with black scales forming two longitudinal median stripes. Eye configuration as male ( Fig. 12A View FIGURES 12 ). Chelicerae and sternum cream-coloured, labium and endites orange. Pedipalpi and legs cream-coloured. Leg spination as male. Opisthosoma elongated, gray, dorsum with sparse white guanine spots and black scales ( Fig. 12A View FIGURES 12 ). Total length 11.3. Carapace 4.0 long, 3.3 wide. Tibia I length 7.3, II 6.6, III 4.4, IV 4.6. Opisthosoma 6.5 long, 1.4 wide.

Variation. Females, total length 7.5–11.3, carapace width 2.5–3.4.

Natural history. The females from Una (IBSP 45232, 47341) were collected by beating understorey vegetation during the day.

Distribution. Colombia to southeastern Brazil ( Fig. 17 View FIGURE 17 ).
