Synonymy. Cletocamptus albuquerquensis sensu Chappuis (1933: 399–400, Figs. 9–11 ) . Etymology. The species has been named after Pierre-Alfred Chappuis ( 1891–1960 ). Type material. The male described by Chappuis (1933) is herein designated as the lectotype and only namebearing type of the species (Art. 74.4, International Commission on Zoological Nomenclature 1999). Type locality. Pos Shiki , Bonaire ; muddy pond; temperature, 31°C; polyhaline. Distribution. Bonaire : Pos Shiki ( Chappuis 1933: 392 ). Redescription (based on the original description in Chappuis 1933 ). Male. Total body length measured from tip of rostrum to posterior margin of caudal rami, 660 µm. General shape as in C. retrogressus . Posterior margin of somites smooth; posterior margin of abdominal somites with continuous row of setules dorsally, ventrally with parallel rows of slender setules (spinules?). Anal operculum rounded, bare. Caudal rami slightly divergent, slightly more than 3 times as long as wide; dorsal seta VII inserted medially on first half of ramus, articulated at its base; setae II and III inserted proximally on outer margin; setae IV, V and VI inserted distally; setae IV and V fused basally; seta VI short. Antennule short, strong, similar to that of C. retrogressus . Exopod of the antenna a single seta. P1 as in the female of C. albuquerquensis ; endopod two-segmented, first segment as long as EXP1, with one inner seta; second segment with three setae. P2 with three-segmented exopod; EXP3 with one inner and two apical setae, and two outer spines: Endopod two-segmented; first segment small, squarish; second segment elongate, reaching tip of EXP1, with one inner and one outer small seta, and one apical long element. P3 with three-segmented exopod; EXP1 about 3 times as long as wide, and about 0.8 times as long as EXP2 and EXP3 combined, without inner armature; EXP2 with inner seta; EXP3 with one inner seta, two apical elements, and two outer spines. Endopod dimorphic, two-segmented; first segment slightly longer than wide; second segment elongate, about 2.8 times as long as wide, reaching slightly beyond EXP1; with short inner apophysis bent outwards at an angle of 90°; with two apical setae. P4 with three segmented exopod; first segment elongate, about 3 times as long as wide and about 0.75 times as long as EXP2 and EXP3 combined, without inner armature; EXP2 with inner seta; EXP3 without inner seta, with two apical setae and two outer spines. Endopod two-segmented; first segment very small, wider than long, without armature; second segment about four times as long as wide, barely reaching proximal seventh of EXP1, with two setae. P5 with fused rami separated only by small notch; both legs fused medially. Baseoendopod with outer seta of basis, endopodal lobe with three subequal setae. Exopod with four setae, of which outermost shortest, apical outer seta longest. P6 a plate without armature. Female. Unknown.
