“ lindahli ” species group

Diagnosis: Eyes normal; male second antennae subcylindrical, generally with the proximal antennomere undifferentiated (except B. constricta ) and the distal antennomere laterally flattened with apex bent medially; female second antennae lacking a medial spine; body lacking sensory papillae; female thoracic segments IV–X (except B. lutalenta , with segments III–VII) always with a dorsolateral subconical or hemispherical projection, segments I and II always lacking projections; first and last limb pairs shortest; ovaries biramal, extending anteriorly from the genital segments into the thorax as far as thoracic segment VI; brood pouch fusiform or cylindrical, extending to abdominal segment IV, V or VI; testes always uniramal extending posteriorly from genital segments into abdominal segment II, III, or IV; cercopods, fringed with setae, flattened and shorter than last two abdominal segments. Species in this group are associated with substrates that have 0–11% gypsum, 3–30% calcium carbonate, and salinity of 0–24 mS/cm ( Rogers 2014a). They are strongly associated with sodium and calcium salts and one species ( B. potassa ) only occurs where potassium salts are present.

Comments: Female B. coloradensis ( “ coloradensis ” species group) also share the same dorsolateral thoracic projections, but the ovary only extends anteriorly to thoracic segment IX. Females in other defined species groups either have no projections, only some of thoracic segments IV–VII with projections but not all, or have the projections as transverse ridges or paired (i.e.; two per side).
