Taxonomic history

Hystripalpus lewisi - Mitrofanov & Strunkova (1979)

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 3 distal setae

Characters

  • opisthosomal setae f2 present (= 7 setae around opisthosomal margin) (Figs. 1, 6, 7)
  • tarsus II with 1 solenidion distally (antiaxial)
  • prodorsum weakly to strongly wrinkled or folded centrally (Fig. 2), can appear to look like areolae (Fig. 3); with longitudinally elongate cells laterally, forming reticulation (Fig. 2), some lateral cells may be fused or open
  • dorsal opisthosoma cuticle between c1-c1 and e1-e1 smooth to wrinkled (Figs. 4, 5); cuticle posterior e1-e1 with a series of weak to strong chevrons (V-shaped folds) (Figs. 1, 4, 6); posterior sublateral cells form distinct bands (Figs. 6, 7)
  • ventral plate with transversely aligned elongate cells, sometimes fusing to form bands (Figs. 8, 9)
  • genital plate with transversely aligned elongate cells, usually forming bands (Figs. 8-9)
  • spermatheca usually a long strong, relatively thick duct, beginning at genital opening between anal plates and genital plate, ending in a small rounded vesicle with a series of short finger-like projections around the dorsal perimeter (Figs. 10-11)
  • the spermathecal vesicle has a distinct transverse clear "bubble" visible internally; the vesicle is generally quite obvious, and is often located near coxae IV
  • palp femur seta thin, tapered, barbed (Fig. 12)
  • palp tarsus with 3 setae
  • trochanter III with 2 setae
