Fig. 10 in New Crayfishes (Decapoda: Parastacidae: Euastacus) from Northeastern New South Wales, Australia
Fig. 10. Lateral and dorsal comparisons of two similar sized specimens of: (A–B) the unusual specimen from Brindle Creek, and (C–D) Euastacus dalagarbe. The unusual specimen has a more elongate body, with a deeper, compressed cephalothorax and a depressed abdomen. The coxae and pereiopods are more pronounced in development, and the pereiopods more elongate. Scale bar represents 5 mm. Photographs: Max Egan.

Fig. 8 in New Crayfishes (Decapoda: Parastacidae: Euastacus) from Northeastern New South Wales, Australia
Fig. 8. Distinguishing features of the sternal keels and lateral processes to the pereiopods in the three species Euastacus girurmulayn, E. guruhgi and E. jagabar. Lateral process pairs (LPr1–5) are numbered in the centre image. (A) Euastacus girurmulayn has close and parallel LPr2, a deflated keel between the LPr3 and LPr4, and well-defined margins to the keel and processes. (B) Euastacus guruhgi has slightly apart to apart and open LPr2, very gradual posterior margins in the LPr3, a broad and deep keel between the LPr3 and LPr4, and blunt margins to the keel and processes. (C) Euastacus jagabar has slightly apart to apart and open LPr2, laterally deflated LPr3, moderate development of the keel between the LPr3 and LPr4, and moderate development and margins to the keel and processes. Photographs are of holotypes (AM P67914; AM P67926; AM P67933).
