Cincticostella szechuanensis View in CoL sp. nov.
Mature larva: (degraded specimens, in ethanol; Figs.14 View FIGURES 14 – 15 a, b); body length 9.5–12.0 mm. Caudal filaments 6.0–8.0 mm. Head with roughened appearance. Mouthparts: labrum with very shallow anteromedian emargination and setae relatively dense situated around margins. Maxilla( Fig.16 View FIGURES 16 – 21 ) somewhat flattened, with row of setae along inner margin; palp with three distinct segments.
14: Dorsal view (a,b). 15: Pro- and Mesothoracic anterolateral projections (magnified image) Thorax: Prothorax expanded laterally, with rounded anterolateral projections. Mesothoracic anterolateral projections blunt and notched medially ( Fig. 15 View FIGURES 14 – 15 ); mesal plate without spines or strong ridges. Femora longer than tibiae, with longitudinal ridge on upper surface and not strongly flattened nor marginally serrate; tibiae longer than tarsi; claw with two proximal denticles.
Abdomen: Abdominal terga without paired spines; posterior margins sometimes sinuate. Gills 3 slightly falcate, with inner margins longer than outer margins. Caudal filaments with very few intrasegmental setae, very few hairlike setae at articulations and small spines at alternate articulations.
Etymology: The specific epithet is a reference to the type locale.
Diagnosis. The new species is distinct among congeners in that it lacks any prominent paired processes on the abdominal terga.
