Antennal flagellum slender with sparse setae 1–3 articles in length near joints of articles.Antennular peduncles not exceeding corneas, or exceeding corneas by less than 0.5 distal length of ultimate segment. Ocular peduncles subcylindrical, slightly narrower near midlength, always marked with distinct dark bands near midlength bordered by white distally and proximally, (often persisting in ethanol preserved specimens). Ocular acicles well separated by rostrum, with narrow anterior projection bifid or multifid, bearing a variable number of accessory spines laterally. Rostrum tapering evenly to an acute point. Cheliped manus dorsomesial margin bearing 3 strong, corneous-tipped spines. Cheliped carpus dorsomesial margins with 4 or 5 strong, corneous tipped, conical spines, color bright carmine red in life. Second pereopod carpus dorsal margin with row of acute spines and third pereopod carpus dorsal margin with 1 or more acute spines distally, bright carmine red in life. First maxilliped with epipod well developed. In life, carapace shield with patches of olive green to light brown, pereopods two and three with light brown to olive green background color, branchiostegites laterally translucent purple with some white spotting. Applicable GenBank sequence accession numbers from Craig & Felder (2021) are as follows for holotype, ULLZ 4782/USNM 1540546: (H3) MW160343; (12S) MW160976; (16S) MW167246. Description. Thirteen pairs of biserial gills. Shield (Fig. 6A, B) sub-triangular, length approximately 1.4 times width. Dorsal surface central region convex; lateral surfaces bearing irregularly spaced small tubercles, spinules, and spines interspersed with sparse setae; anterior margins between rostrum and lateral projections distinctly concave, paralleled by well-defined marginal ridge; anterolateral angle obtuse and rounded bearing numerous irregularly spaced spines and spinules. Rostrum triangular, extending anteriorly beyond lateral projections, lateral margins sloping evenly to acute point and bearing fringe of setae. Lateral projections acute. Branchiostegite lateral surface with granular texture nearly obscured by tufts of long setae. Posterior carapace poorly calcified, lateral surfaces bearing scattered setae. Ocular peduncles (Fig. 6A) subcylindrical, slightly narrower at midlength, diameter at base approximately equal to that of cornea, left longer than right; dorsomesial surface bearing tufts of long setae proximally. Ocular acicles (Fig. 6A) subtriangular, mesial borders unarmed and separated by rostrum; anterior projection bifid or multifid, lateral margin bearing 1 or more acute spines. Antennular peduncles (Fig. 6A) not extending anteriorly beyond cornea distal margin in holotype (exceeding cornea distal margin by approximately 0.5 length of ultimate segment in some paratypes); basal segment lateral surface bearing small spine. Antennal peduncles (Fig. 6A) not extending anteriorly beyond cornea distal margin. Fifth segment without remarkable characteristics. Fourth segment dorsodistal angle bearing anteriorly angled spine. Third segment ventromesial distal angle bearing strong spine, somewhat obscured from dorsal view by dense fringe of setae. Second segment dorsolateral distal angle forming anterior projection terminating in single spine, lateral margin somewhat oblique, bearing 3 spines, dorsomesial distal angle bearing single spine. First segment dorsolateral distal angle bearing minute spine. Antennal acicles extending slightly beyond 0.5 mid-length of ocular peduncle, terminating in single spine; lateral margin bearing 2 or more spines (number variable among paratypes) interspersed with tufts of long setae; mesial border with 1 or more (number variable among paratypes) widely spaced spines partially obscured by dense fringe of setae. Antennal flagellum not extending beyond fingertips, sparse setae approximately 1–3 articles in length at joints of flagellar articles. Mandible (Fig. 6F) with incisor edge calcareous; ultimate segment of palp broad, setose, length equal to combined length of penultimate and basal segments. Maxillule (Fig. 6E) proximal and distal endite mesial margins densely setose; endopod internal lobe distal angle bearing sparse tuft of bristles, external lobe recurved, length approximately 0.7 times that of internal lobe, terminal angle bearing sparse setae. Maxilla (Fig. 6C) proximal and distal endite mesial margins densely setose; endopod tapered distally, not overreaching distal apex of scaphognathite; scaphognathite recurved, margins densely setose. First maxilliped (Fig. 6D) proximal and distal endite mesial margins densely setose; endopod length approximately 0.7 times that of exopod; exopod tapering distally, lateral margin densely setose, flagellum elongate and densely setose; epipod well developed, margins densely setose.
