BRASILIBATHYNELLOCARIS PANAMERICANA ‘FORMA TRUNCATA’

Parastenocaris panamericana f. truncata – Noodt (1962: 230); Rouch (1986), Dussart & Defaye (1990). Material examined: Specimens from sample S 114 ( Noodt, 1962); from this sample, Noodt prepared 12 slides now stored at DZMB (Noodt collection, box 6, slide nos. 9–20); only slides 9–13 carry members of B. panamericana ‘f. truncata’, as follows: three males each (nos. 9, 10); four, three, and one female, respectively (nos. 11–13).

Collecting locality: El Salvador, groundwater from beach of a small rocky sea bay near La Fochota (south of La Union).

Diagnosis: Males of B. panamericana ‘f. truncata’ are similar to those of the nominotypical form in all characters. Females differ in the following characters: furca ( Fig. 11B ; see also Noodt, 1962: 229, figs 15, 16, and 232, figs 26–28) seta IV reduced to a slender spine; seta V reduced to a stout spine, with several setules arranged distally; other setae developed as in male. Leg 5 rectangular, with an inner process, an intercoxal plate, an outer basal seta, but lacking the most proximal exopodal seta, as in male Noodt (1962: 231, fig. 19).
