Taxonomy from Schweitzer et al. 2014.
Quote (Schweitzer et al. 2014, p. 457): "Although the lobsters were interpreted as having relatively durable cuticle, the shrimp discussed herein are characterized by having very thin cuticle that is readily deformed and oriented in a variety of positions. As a result, the description and interpretation of the morphology of the shrimp is, of necessity, a composite of several specimens; however, fine detail of many parts of the skeletal anatomy is exquisite."
Diagnosis from Schweitzer et al. 2014, p. 467: "Carapace longer than high; rostrum very long, 40 percent length of carapace, with one basal suprarostral spine and one subrostral spine at midlength; uropodal exopod with diaeresis; ventral lateral margins of telson with setal pits, appearing to extend entire length of telson; third maxilliped about as long as first and second pereiopods, with spine bases or setal pits along propodal and dactyl ventral margin; pereiopods 1– 3 chelate, third pereiopod longest, fourth and fifth longer than first and second, pereiopods without spines; pleopods apparently with multiarticulate flagellae."
Identified by oilshale using Schweitzer et al. 2014. Characteristic is the extremely long rostrum, constituting 40 percent of the carapace length.
