Pseudomicippe varians Miers, 1879 First View in CoL zoea
( Figure 1 View Figure 1 )
Carapace ( Figure 1A View Figure 1 ). Dorsal, rostral, and lateral spines absent. Ventral margin posterior to scaphognathite notch with small plumodenticulate seta preceding densely plumose ‘‘anterior seta’’, followed by five plumose setae. Eyes sessile. Small indistinct median ridge frontally and a small median tubercle on posterodorsal margin, each bearing cuticular dorsal organ (sensu Martin and Laverack 1992). Pair of simple setae present on posterodorsal margin.
Antennule ( Figure 1B View Figure 1 ). Unsegmented, smooth, conical. Terminally bearing two long, two shorter aesthetascs.
Antenna ( Figure 1C View Figure 1 ). Biramous, spinous process of the protopod pointed, bearing two rows of sharp spinules; endopod bud present with half of the exopod length; onesegmented exopod shorter than protopod with two subterminal setae with similar size.
Mandible ( Figure 1D View Figure 1 ). With medial toothed molar process and much enlarged lateral incisor processes, as long as antenna. Palp absent.
Maxillule ( Figure 1E View Figure 1 ). Epipod seta absent. Coxal endite bearing seven setae, four terminal setae (two plumodenticulate and two graded plumodenticulate), subterminally with three plumodenticulate setae. Basial endite with three terminal cuspidate setae and four subterminal setae, three plumodenticulate and one plumose. Two-segmented endopod with proximal segment bearing plumodenticulate seta, distal segment bearing two pairs of plumodenticulate setae apically. Exopod seta absent.
Maxilla ( Figure 1F View Figure 1 ). Coxal endite bilobed, proximal lobe with three setae, two plumose and one plumodenticulate; distal lobe with four setae, three plumose and one plumodenticulate. Basial endite bilobed, proximal and distal lobes with four to five and four plumodenticulate setae, respectively. Microtrichia present on both endites. Unsegmented endopod unilobed, with four apical plumodenticulate setae; microtrichia on lateral margin. Scaphognathite with 18 marginal densely plumose setae, including distal process.
Maxilliped 1 ( Figure 1A, G View Figure 1 ). Coxa naked. Basis with nine plumodenticulate setae arranged 2,2,2,3. Endopod five-segmented with 3,2,1,2,5 (one subterminal, four terminal) plumodenticulate setae. Bisegmented exopod with four terminal plumose natatory setae.
Maxilliped 2 ( Figure 1A, H View Figure 1 ). Coxa naked. Basis with three plumodenticulate setae. Endopod three-segmented, with 0,1,6 plumodenticulate setae of different types, two anterior, two medial, two apical on terminal segment. Bisegmented exopod with four terminal plumose natatory setae.
Maxilliped 3 ( Figure 1I View Figure 1 ). Biramous. Endopod, exopod and epipod present
Pereiopods ( Figure 1I View Figure 1 ). Present with bilobed chela.
Abdomen ( Figure 1A, J View Figure 1 ). Five somites. Somite 1 with pair of middorsal plumodenticulate setae, somites 2–5 each with pair of shorter posteromedial simple setae. Posterolaterally, somites 2, 4 and 5 with blunt process, somite 3 with spine; somite two with pair of dorsolateral processes. Grouped denticulettes present. Pleopods absent.
Telson ( Figure 1J View Figure 1 ). Bifurcated, distinct median notch, three pairs of plumodenticulate setae on inner margin; each furcal shaft proximally bearing lateral spine, furcal shafts and spines covered in rows of spinules to just below tips. Grouped denticulettes present.
Second zoea ( Figure 2 View Figure 2 )
Carapace ( Figure 2A View Figure 2 ). Eyes stalked. Posterolateral margin with nine setae, one densely plumose followed by eight plumose setae.
Antennule ( Figure 2B View Figure 2 ). With four long aesthetascs and one short simple seta, endopod bud present.
Antenna ( Figure 2C View Figure 2 ). Endopod bud enlarged to beyond middle of protopodite.
Mandible ( Figure 2D View Figure 2 ). Palp bud absent.
Maxillule ( Figure 2E View Figure 2 ). Basial endite now with eight setae, three terminal cuspidate setae and five subterminal setae, four plumodenticulate and one plumose. Exopod pappose seta present.
Maxilla ( Figure 2F View Figure 2 ). Scaphognathite with 28 marginal plumose setae.
Maxilliped 1 ( Figure 2A View Figure 2 ). Exopod with six plumose natatory setae.
Maxilliped 2 ( Figure 2A View Figure 2 ). Exopod with six plumose natatory setae.
Maxilliped 3 ( Figure 2H View Figure 2 ). Developing. Endopod showing segmentation.
Pereiopods ( Figure 2H View Figure 2 ). Longer, chela enlarged. Some segmentation apparent.
Abdomen ( Figure 2G View Figure 2 ). Additional sixth somite. Somites 2–5 with posterolateral spines, a pair of unsegmented biramous pleopods on somites 2–5, endopods very small.
Telson ( Figure 2G View Figure 2 ) Unchanged.
