The results showed that the length and width of mouth hooks and of the pharyngeal sclerite exhibited 3 distinct distribution areas (Fig.
4A) protopod large, modified to form apron, with 1 outer plumose seta situated near base of exopod, 1 inner plumose seta near large intercoxal sclerite, 1 proximolateral corrugated pad on dorsal surface, 3 marginal membranes, minute pores scattered on ventral surface, and 2 unequal sensilla along posterior margin.
This sclerite was identifiable as a distal apophysis because of its position on the apical part of the tegulum and because of its dual connection through flexible membranes with the apical part of tegulum and the basal part of embolus.
2a), no sclerite slide exists: trowel-like with long stem, 0.
Phallosome simple, open anteriorly, with aedeagal arch pointed and external parameres slender, incurved, bearing pores distally; lacking endophallic sclerites, but with a radula slit in the middle (Figs.
Helicoradomenia belongs to the neomenioid aplacophorans, which are narrow or wide cylinder-shaped molluscs ("wormshaped" in the literature) covered by aragonite sclerites held by body mantle cuticle--the scleritome.
20) Basal sclerite (R3), two states: present (0), absent (1).
Mesocyclops oganmts female: (A)--General aspect; (B)--Antenna 2 (setae: longitudinal spines rows); (C)--Maxillulary palp (setae: rows of spines); (D)--Intercoxal sclerite of leg 4 (setae: projection); (E)--Genital segment (setae: lateral ami of the seminal receptacle); (F)- Caudal rami (setae: naked inner margin).
Within the genus Rhacocleis there is no other taxon that shows in the female sex the combination of a subgenital plate with a transverse fold, the apical sclerite semi-circular with a moderate incision in the hind margin and the basal sclerite nearly unmodified except for a median keel.
39 mm; mouth hook (MH) with bifid hook anteriorly, without accessory tooth, posterior margin fused with complex hypostomal-pharyngeal sclerite; ventral arch (VA) beneath and articulated with mouth hook, anterior margin finely denticulate, lateral edges slightly emerged; pharyngeal sclerite (PS), apex of dorsal cornu very tapered (Dc), ventral cornu (Vc) clear, without window.
Body length was recorded from the front to the apex of the abdomen, and the wing length was taken from the alar sclerite to the wing apex.
