Taxonomic history

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 shape to dorsal lateral setae (c3, d3, e3); palp 4-segmented with 2 distal setae

Characters

  • opisthosomal setae f2 present (= 7 setae around opisthosomal margin) (Figs. 1, 6)
  • tarsus II with 1 solenidion distally (antiaxial); solenidia on tarsus I-II long (Fig. 2)
  • prodorsum smooth centrally, with some weak wrinkles; with rounded closed cells laterally, forming strong pebble-like reticulation (Figs. 3, 4)
  • anterior projection of prodorsum with strong pebble-like reticulation (Fig. 4)
  • dorsal opisthosoma cuticle between c1-c1 and e1-e1 smooth to weakly wrinkled (rugose) (Fig. 5); cuticle laterad c1 with pebble-like reticulation; cuticle posterior e1-e1 with weak transverse folds and large rounded cells (Figs. 5, 6)
  • seta f3 inserted off the body margin, medad f2 (Fig. 6)
  • almost the entire ventral surface of body with strong pebble-like reticulation (Fig. 7)
  • ventral plate not well defined, with small to medium circular cells (Figs. 8, 9)
  • genital plate with large rounded cells transversely aligned (Figs. 8, 9), cells often fused to form transverse bands/folds (Fig. 9)
  • spermatheca not visible
  • palp tibia with protuberance; seta on femur strong, tapered, lightly barbed (Fig. 10)
  • palp tarsus very small, with 2 setae - 1 solenidion, 1 eupathidion (Figs. 10-11)
  • trochanter III with 1 seta (Fig. 12)
  • ventral setae 3a and 4a very short (Fig. 12)
