Short description Morphology

Carapace with three distinct acute teeth in the median line before the cervical groove (the gastric, pregastric and rostral teeth). Region between the postrostral and branchial carinae with only few tubercles and with extensive smooth areas. Abdomen without a sharp elevated median longitudinal carina, but each abdominal somites 2 to 5 with an elongate lobulate figure in the middle. The exposed part of the abdominal somites 2 to 5 with an arborescent arrangement of very narrow grooves. Somite 1 with a complete transverse groove, behind which there are numerous short longitudinal grooves that may be rather irregular in shape and sometimes are interconnected by transverse grooves; this posterior part of somite 1 is no longer in the middle than laterally. The smooth anterior half of abdominal somites 2 to 6 (i.e., the part that disappears under the tergum of the previous somite when the abdomen is fully stretched) on either side with a short transverse groove in which hairs are implanted. Fourth segment of antenna with a single oblique median carina. Outer margin of the segment with 2, the inner margin with 3 or 4 teeth (not including the apical tooth). Thoracic sternum anteriorly U-shapedly incised in the middle. A blunt and low but conical tubercle on the last thoracic sternite. Dactyli of legs without fringes of hair. Colour: pale brownish or pinkish with patches of darker hairs. Two dark spots on the dorsal face of the first abdominal somite in the sibmedian region (Ref. 4).

It has lengths of 5.5 cm, maximum total length, usually not more than 4 cm; 1 cm (males) and 1.15 cm, (females) (Ref. 4). Maximum depth is from Ref. 119076.
