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)
- tarsus II with 1 solenidion distally (antiaxial)
- prodorsum reticulate centrally, some cells fused together to form larger irregularly shaped cells (Figs. 1-6); with large closed cells laterally, forming reticulation (Figs. 2-5); lateral cells sometimes fused (Fig. 4)
- dorsal opisthosomal cuticle between c1-c1 and d1-d1 with large closed cells forming reticulation (Figs. 7-9); cuticle between d1-d1 and e1-e1 with fused irregularly shaped cells; cuticle posterior to e1-e1 with a series of short transverse folds (Figs. 2, 9, 10, 11)
- ventral plate with small to medium circular cells (Figs. 12, 13), some cells fused to form transversely elongate cells (Fig. 14)
- genital plate with large, rounded cells (Figs. 12, 13, 14), some cells fused to form transversely elongate cells (Figs. 12, 14)
- 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 short finger-like projections around most or all of the perimeter (Figs. 15, 16); the vesicle is generally quite visible, and is often located near coxae IV
- palp femur seta thin, tapered, barbed (Fig. 17)
- palp tarsus with 3 setae
- trochanter III with 2 setae
- deutonymph with setae c3, d3, e3 as long as f3, h1-2 (B. obovatus deutonymph with c3, d3, e3 shorter than f3, h1-2) (Fig. 18)
