The acutidens View in CoL group of Mago (newly proposed)

Diagnosis. Species of this group are promptly recognized among the other Mago by the RTA bearing two linked branches in the male palp: one more ventral, which is a roundish lobe along the axis of the palp, and one more dorsal and perpendicular to the axis of the palp, which is a short and acute apophysis pointing dorsally ( Figs 11– 12 View FIGURES 7 – 12 ). The embolus emerges proximally at the prolateral tegulum and has an intumescence that fits into a concave portion of the tegulum; the embolus can bear projections on its median portion and is thin distally ( Figs 7–10 View FIGURES 7 – 12 , 13– 16 View FIGURES 13 – 18 ). Also, while most species of Mago have lost the amycine mastidia of the male chelicerae, the species of the acutidens group have kept them (see Figs 17–18 View FIGURES 13 – 18 ).

Description of common features. Male with reddish brown carapace, dorsally with white scales between the two AME and laterally between the ALE and the PLE ( Figs 1, 4, 5 View FIGURES 1 – 6 ). Female with orange cephalic area and yellow thoracic area ( Fig. 3 View FIGURES 1 – 6 ). Clypeus with sparse white scales in males ( Fig. 5 View FIGURES 1 – 6 ). Chelicera brown, with several small promarginal teeth and a large pluridentate tooth on retromargin in both sexes ( Figs 19–20 View FIGURES 19 – 22 ). Labium and endite brown and sternum yellowish in both sexes ( Fig. 2 View FIGURES 1 – 6 ). Male palp with coxa, trochanter, proximal and medial femur brown, distal femur and patella yellow. Female palp yellow, with tibia and tarsus darker. Male leg I with all articles reddish brown. Leg II with coxa, trochanter and proximal and medial femur yellow; distal femur, patella, tibia, metatarsus and tarsus reddish brown. Legs III and IV with the same color pattern as II; IV with median tibia yellow ( Fig. 1 View FIGURES 1 – 6 ). Female with all legs yellow ( Fig. 3 View FIGURES 1 – 6 ). Leg spines in both sexes: femur I d1-1-1, p0-0-2, r0-0-1; II d1-1-1, p0-0-2, r0-0-2; III d1-1-1, p0-1-2, r0-0-1; IV d1-1-1, p0-0-1, r0-0-1; patella I–II p1, r0; III–IV p1, r1; tibia I–II p1- 0-1, v2-2 -2; III p1-0-1, r1-1-1, v1 p-0-2; IV p0-1-1, r1-1-1, v1 p-0-2; metatarsus I–II v2-2; III p1-0-2, r1-0-2, v2 -0- 2; IV p1-0-2, r1-1-2, v1 p-0-1r. Abdomen with the dorsal pattern described for the genus (see generic diagnosis) in both sexes; ventrally with a wide dark brown longitudinal stripe in both sexes ( Fig. 2 View FIGURES 1 – 6 ). Female with two separate copulation openings on the epigynal plate and two pockets on posterior border separate by a median notch ( Fig. 32 View FIGURES 30 – 36 ); internally with small glands ( Figs 21–22 View FIGURES 19 – 22 ) on short copulation ducts, leading to undifferentiated, posterior spermathecae, from which fertilization ducts emerge. Spinnerets mostly dark brown.
