A–B, F). Sympod on its mesial margin with small lobe bearing a minute spine at tip. Peduncle 3-segmented, whereby segments 1–3 contribute 9–11%, 40–44%, and 47–49% to total peduncle length. Mesial margin of basal segment with small lobe ending in a large spine. Flagellum tiny, short, 6-segmented. Antennal scale extends slightly beyond antennal peduncle, i.e., clearly beyond basal segment of antennular trunk. Scale 0.6 times length of carapace; scale length six times maximum width. Scale subdivided by a slightly oblique articulation; apical segment 4–5% total scale length.

A–C). Palpus ³⁄2 length of carapace; segments 1–3 contribute 8–9%, 58–60%, and 32–33% to total length, respectively. Basal (first) segment laterally with spine on the tip of a triangular lobe. Analogous, smaller structure set subbasally on outer margin of median segment; apart from that, outer margin smooth all along; inner margin almost all along with numerous smooth, in part spine-like, long setae with shorter ones in between. Terminal segment reflexed, together with seven very long, strong setae rendering the palpus a large prehensile appendage. Left mandible with large processus incisivus ending in three blunt teeth; lacinia mobilis well developed with four, mostly less blunt teeth; pars centralis reduced to a single finger-like process; processus molaris with weakly sclerotized ridges and with ventral and dorsal ridges of stiff bristles. Right mandible with large processus incisivus bearing three rounded lobes representing surrogates of teeth; no lacinia mobilis developed; pars centralis reduced to a finger-like process; processus molaris trilobate.
