Branchinecta paludosa (Muller, 1788)

Rogers, D. Christopher & Aguilar, Andres, 2020, Fig. 8 in Stiatoandricus nievesaldreyi Cuesta-Porta & Melika & Nicholls & Stone & Pujade-Villar 2022, Zoological Studies 59 (14), pp. 1-17 : 11

“ paludosa ” species group

Diagnosis: Eyes normal; male second antennae subcylindrical, pulvilli lacking (except in B. kaibabensis , which has each pulvillus borne on a subconical mound) with the proximal antennomere medial surface with a single, longitudinal row of spines, and the distal antennomere not flattened, tapering, with apex directed distally; female second antennae lacking a medial spine; body lacking sensory papillae; female thoracic segments smooth (except B. serrata which has a dorsolateral conical protrusion on segments III– VII; first and last limb pairs shortest; ovaries biramal extending anteriorly from the genital segments into the thorax as far as thoracic segment VII or VI; brood pouch fusiform or pedunculate, extending to abdominal segment VII; testes uniramal, extending posteriorly from genital segments into abdominal segment III or IV; cercopods, fringed with setae, flattened and shorter than last two abdominal segments. This species group is associated with substrates lacking gypsum, 0–10% calcium carbonate, and 0–2 (rarely) mS/cm substrate salinity ( Rogers 2014a).

Comments: Branchinecta longiantenna in the “ packardi ” species group has the second antenna proximal antennomere bearing spines in several longitudinal rows, not just one. Branchinecta cornigera , also of the “ packardi ” species group, has the second antennae distal antennomere not flattened and tapering, but lacks a longitudinal spine row on the proximal antennomere. The “ raptor ” and “ ferox ” species groups also have the second antenna distal antennomere tapering, but are separated from this group by the form of the cercopod.
