Species group characters

B. obovatus species group (sensu Baker & Tuttle 1987) = f2 absent; tarsus II with 1 solenidion; dorsal central setae (c1, d1, e1) different shape to dorsal lateral setae (c3, d3, e3); palp 4-segmented with 3 distal setae

Characters

  • opisthosomal setae f2 absent (= 6 setae around opisthosomal margin) (Figs. 1, 7, 8)
  • tarsus II with 1 solenidion distally (antiaxial)
  • prodorsum mostly smooth centrally, or with weak wrinkles (Figs. 2-5); strongly reticulate laterally, with large cells posteriorly and small cells anteriorly (Figs. 2-5)
  • dorsal opisthosoma cuticle between c1-c1 and e1-e1 weakly reticulate to weakly wrinkled (Figs. 6, 7); cuticle between and posterior to e1-e1 with a series of short, transverse folds (Figs. 6-11); posterior sublateral cuticle with cells present to the body margin (Figs. 7-10)
  • ventral plate with small rounded cells (Figs. 12-14), often central cells fusing to form weak transverse bands (Figs. 13, 14)
  • genital plate with medium to large rounded cells (Figs. 12, 13, 14), sometimes transversely aligned
  • spermatheca with a long duct, beginning at genital opening between anal plates and genital plate, ending in a small rounded vesicle covered in short finger-like projections, around the entire perimeter (Figs. 15, 16, 17); usually quite visible, often located near coxae IV
  • palp femur seta varies from a broad flat seta with few barbs (Fig. 18), to a thin, tapered, weakly barbed seta (Figs. 19, 20)
  • palp tarsus with 3 setae
  • trochanter III with 2 setae
  • deutonymph with setae c3, d3, e3 shorter than f3, h1-2 (Fig. 21) (B. chilensis deutonymph with setae c3, d3, e3 as long as f3, h1-2
