Stenothoe dollfusi Chevreux, 1887

Fig. 10

Chevreux, 1887: 327, p. XXXIII, fig. 8; 1891: 260, fig. 6–8, 10 (not fig. 9); 1900: 53, pl. 8, fig. 1; Chevreux & Fage, 1925:135, fig. 134: all but Gn 2 male

Krapp-Schickel, 1976: 12, fig. 11–13 (fig. 13 not Gn 2 male); 1993: 697 fig. 477: all but Gn 2 male

Chevreux, 1891 illustrated in his original description (as well as the following ones in 1900 and Chevreux & Fage, 1925) not only the male of his new species St. dollfusi (in fig. 6), but additionally also of the much later described St. eduardi Krapp-Schickel, 1976 (in Chevreux 1887 fig. 9), causing the repetition of this confusion even in the same paper Krapp-Schickel 1976: 12, fig. 13 as well as in Krapp-Schickel 1993: 697, fig.477. Of course the allometry of Gn2 propodus could have led to a longer size and slimmer width, but the very typical semicircular excavation, shown in fig. 6, is totally lost in his fig. 9, which he does not discuss.

Fact is, that both sexes have quite similar second gnathopods with the typical excavation, which is shallow in juveniles.

Here finally the correction of this more than 100 years old mistake.
