A modern description ofCrambionella stuhlmanni(Scyphozoa: Rhizostomeae) from St Lucia Estuary, South Africa

Abstract

A new record of Crambionella stuhlmanni is reported from the east coast of South Africa. The material is described using quantitative morphological data, and mitochondrial (CO1) and nuclear (ITS-1) sequence data. The species can be diagnosed by a combination of morphological features including the presence of conical projections on velar lappets, the absence of orbicular appendages among mouthlets and the short length of the terminal club on the oral arm. Mitochondrial sequence data unambiguously delineate C. stuhlmanni as a separate species from C. orsini, and phylogenetic analyses support its placement within the monophyletic genus, Crambionella.

A new species of the commercially harvested jellyfish Crambionella (Scyphozoa) from central Java, Indonesia with remarks on the fisheries

“…, St Lucia Estuary, South Africa(Neethling et al, 2011;Perissinotto et al, 2013) * Cilacap, central Java, Indonesia (this study; Nishikawa et al, 2009; Kitamura & Omori, 2010), Karang Duwur (Nishikawa et al, 2009) new species of commercially harvested jellyfish crambionella bell diameter), and (4) intermediate length of terminal clubs relative to oral-arm length, i.e. .2 times longer than C.…”

“…However, it is readily distinguishable from the latter by the absence of tubercles on the velar lappets as well as by the relative length of the terminal clubs to the entire oral arms (0.28 vs 0.5) (see Table 5, Rao, 1931;Neethling et al, 2011). While, C.…”

Redescription of the enigmatic jellyfish,Crambionella annandalei(Cnidaria: Scyphozoa) from Indian waters

“…has been observed for some C. stuhlmanni from the St Lucia Estuary, South Africa (Neethling et al, 2011cf. Perissinotto et al, 2013.…”

“…The specimens were brought to the laboratory and photographed, and the umbrella diameter (mm) and wet weight (g) individually determined. A total of 33 morphological features were measured from the fresh specimens using digital Vernier callipers (Table 1 & Figure 3A-F), following Neethling et al (2011) and Nishikawa et al (2014). The canal systems were injected with Rose Bengal to highlight their arrangement, after which specimens were preserved in 10% formalin.…”
