Enallopaguropsis guatemoci (Glassell, 1937) View in CoL
( Figs. 1 View FIGURE 1 A–E, 2A–G)
Material examined. The ovigerous female used in this study (LC = 2.1 mm) had 17 eggs, but only eight zoeae hatched (four zoea measured and/or dissected), 19 April 2011 (ICML-EMU 10879). Size of zoeae, CL= 1.40 ± 0.03 mm (1.37–1.43 mm).
Description. Carapace ( Fig. 1 View FIGURE 1 A, B). Moderately truncated, dorsolateral angles rounded, with dorsomedial keel extending to posterior margin; eyes sessile; pterygostomial region slightly produced; rostrum slightly deflected ventrally, long, moderately slender, slightly overreaching antennae.
Antennule ( Fig. 1 View FIGURE 1 A, D). Subcylindrical, weakly segmented, shorter than antennae; 2 aesthetascs and 3 or 4 moderately long simple setae terminally; 1 long terminal plumose seta on endopodal bud.
Antenna ( Fig. 1 View FIGURE 1 A, E). Exopod (scaphocerite) with moderately strong distal spine, inner margin convex with 8 long and 1 short plumose setae; endopod approximately three-fifths length of scaphocerite, with 2 long terminal plumose setae; protopod with strong serrate spine at base of endopodal junction.
Mandibles ( Fig. 2 View FIGURE 2 A, B). Asymmetrically dentate; incisor processes with 1 strong tooth 1 or more smaller teeth; molar processes with several acute denticles and teeth; no palp bud.
Maxillule ( Fig. 2 View FIGURE 2 C). Endopod 3-segmented, with 0 or 1, 1, 2 simple setae; coxal endite with 5 marginal plumose setae, 1 simple seta and 1 simple submarginal seta; basial endite with 2 strong teeth, each armed with several prominent accessory denticles, 1 simple marginal seta and 1 short, simple, submarginal seta.
Maxilla ( Fig. 2 View FIGURE 2 D). Endopod bilobed, proximal lobe with 1 submarginal and 2 marginal plumodenticulate setae, distal lobe with 3 plumodenticulate marginal setae and outer margin with microtrichia; coxal and basal endites bilobed, proximal lobe of coxal endite with 1 submarginal and 6 marginal plumodenticulate setae and 1 lateral plumodenticulate seta, distal lobe with 1 submarginal and 2 or 3 marginal plumodenticulate setae; proximal lobe of basial endite with 1 submarginal and 3 marginal plumodenticulate setae, distal lobe with 1 submarginal and 3 marginal plumodenticulate setae; exopod (scaphognathite) fused to protopod, distal lobe with 5 marginal plumose setae, inner margin with microtrichia.
First maxilliped ( Fig. 2 View FIGURE 2 E). No coxal seta; basis with 9 setae arranged 1, 2, 3, 3; endopod 5-segmented, setation (proximal to distal) 3, 2, 1, 2, 4 + I (I= an additional dorsolateral plumose seta); exopod 2-segmented, 4 long terminal, plumose natatory setae.
Second maxilliped ( Fig. 2 View FIGURE 2 F). No coxal setae; basis with 1 marginal plumodenticulate seta in distal half, 2 plumodenticulate setae at inner, distal angle; endopod 4-segmented, segments 1–3 each with 2 plumodenticulate setae, distal segment with 4 + I plumose seta; exopod 2-segmented, 4 long terminal plumose, natatory setae.
Third maxilliped ( Fig. 2 View FIGURE 2 G). Exopod unsegmented, smooth, with pointed or blunt tip.
Abdomen ( Fig. 1 View FIGURE 1 A, B). Five somites and telson; first and second somites unarmed; posterodorsal margins of somites 3–5 each with pair of moderately long spines, posterolateral margins each with spines increasing in size distally.
Telson ( Fig. 1 View FIGURE 1 A, C). Fused with 6th somite, moderately long, somewhat fan-shaped posteriorly; posterior margin with small V-shaped median notch, microtrichia and 7 + 7 setae (1, ii, 3–7), outermost (1st) unarmed, articulated, 2nd anomuran hair (ii), 3rd through 7th articulated, with plumose setae, 4th the longest, 0.70 times the width of telson measured at posterior margin; anal spine absent.
