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 : 9

“ ferox ” species group

Diagnosis: Eyes normal; male second antennae arcuate and subacute; female second antennae lacking a medial spine; body lacking sensory papillae; female thoracic segments lacking any dorsolateral projections; first and last limb pairs shortest; ovaries uniramal limited to the abdomen (except B. ferox , which is biramal, extending anteriorly to thoracic segment X), and posteriorly in the abdomen to abdominal segment IV, V, or VI; brood pouch fusiform, extending to abdominal segment III, IV, V or VI; testes always uniramal extending posteriorly from genital segments into abdominal segment IV, V, or VI; cercopods cylindrical, tapering, shorter than the last two abdominal segments, medial surface with setae, lateral surface with or without setae. No geochemical association data is available.

Comments: Three species, morphologically similar to B. raptor in the overall general form of the male second antennae and the cylindrical cercopods. However, in B. raptor the cercopods are glabrous, whereas in the ferox group, marginal setae are always present medially in all three species, but on the lateral side may only be present distally or not at all in B. ferox and B. orientalis .
