Baker, Tuttle and Abbatiello

Species group characters

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


  • opisthosomal setae f2 present (= 7 setae around opisthosomal margin) (Fig. 4)
  • tarsus II with 1 solenidion distally (antiaxial)
  • dorsum covered in distinct pebble-like reticulation (Figs. 1, 2, 4)
  • prodorsum with distinct pebble-like pattern on cuticle, large strong rounded cells (Fig. 2)
  • dorsal opisthosomal cuticle between c1-c1 and d1-d1 smooth to weakly folded (Fig. 3); cuticle between d1-d1 and e1-e1 with some transverse folds (Fig. 3); cuticle around body margin with distinct pebble-like pattern (Fig. 4)
  • anterior dorsal setae large, broadly spatulate (Figs. 2, 3)
  • venter with distinct pebble-like cuticle (Fig. 5)
  • ventral plate with medium to small rounded cells, sometimes forming transverse bands (Fig. 6)
  • genital plate very large cells; genital setae long (Fig. 6)
  • spermatheca with long duct, ending in simple bulb (Fig. 7)
  • palp femur seta thin, tapered, weakly barbed (Fig. 8)
  • palp tarsus with 3 setae
  • trochanter III with 2 setae
  • deutonymph with distinctive long sc1, sc2 setae on prodorsum (Fig. 9)
