Genus Stylopandalus Coutiére, 1905 View in CoL

( Figs. 7 View FIGURE 7 , 8 View FIGURE 8 )

Stylopandalus Coutiére, 1905: 115 View in CoL ; Chace, 1985: 135; Holthuis, 1993: 278.

Diagnosis: Rostrum immovably attached to carapace, armed with fixed teeth on both margins. Carapace without supraorbital spine and lateral carinae; dorsally carenate anteriorly, rounded posteriorly. Third abdominal somite bearing movable posteromesial stout seta (frequently lost). Cornea wider than eyestalk. Second maxilliped with terminal segment longer than wide. Maxilliped 3 with exopod. Pereopods without epipods; pereopod 2 with carpus subdivided in to more than three articles (modified from Chace, 1985).

Remarks: Chace (1985) affirms that the single species that prompted Coutière (1905) to propose the subgenus Stylopandalus seems sufficiently distinct from the members of the genus Plesionika to justify generic recognition. The author pointed that the most significant feature, taxonomically, is the elongate terminal segment of the maxilliped 2 ( Fig. 8 View FIGURE 8 A). Also of generic importance, is the slender movable spine in abdominal somite 3 (but it is frequently lost), and the appendix masculina on pleopod 2 unusually slender, with long stout setae along the anterior margin ( Fig. 8 View FIGURE 8 B). The dactyls of pereopods 3–5 with single distal long stout setae were incomplete (in more than a half of their length, Fig. 8 View FIGURE 8 C) in Brazilian material observed herein.
