Species group characters

B. portalis species group (sensu Baker & Tuttle 1987) = f2 present; tarsus II with 1 solenidion; dorsal central setae (c1, d1, e1) similar in shape to dorsal lateral setae (c3, d3, e3); palp 4-segmented with 2 distal setae


  • opisthosomal setae f2 present (= 7 setae around opisthosomal margin) (Figs. 1, 2, 7, 8)
  • tarsus II with 1 solenidion distally (antiaxial)
  • long dorsal setae; dorsal cuticle with distinct reticulation (Figs. 1, 2)
  • prodorsum with strong pebble-like reticulation over most of cuticle, most cells closed, with a few fused cells centrally (Figs. 3, 4, 5); lateral margin with cells fused to form a distinct series of transverse/oblique bands (Fig. 3)
  • dorsal opisthosoma cuticle between c1-c1 and d1-d1 reticulate with large closed cells; cuticle between d1-d1 to posterior of e1-e1 with series of transverse folds (Figs. 6, 7); cuticle around lateral margin with distinct series of transverse folds (Fig. 8)
  • ventral plate with small to medium rounded cells (Figs. 9, 10), often fused to form weak bands (Fig. 11)
  • genital plate with large cells, somewhat transversely elongate (Figs. 9, 10, 11)
  • spermatheca not visible
  • palp tarsus with 2 setae distally = short solenidion and long eupathidion (Figs. 12, 13)
  • palp femur seta thin, tapered, finely barbed (Fig. 14)
  • trochanter III with 2 setae
