Acetes sibogae sibogae   Hansen,  1919 (Shrimp)
Organism information awaits expert curation
Class: Malacostraca

Size: Body length - Females 14-27 mm; males 13-20 mm

In the females the lower antennular flagellum is 11 to 20 segmented. The distal inner margin of the basis of the third pereiopod ends in a projection; the coxa has a tooth on the distal inner margin. In the genital area the third thoracic sternite forms a fairly large plate, the lateral and posterior margins of which are elevated; there is a pair of small protuberances on the anterior part; the posterior margin may produce slightly backwards medially, so that the deep transverse furrow between the third and fourth thoracic sternites is recurved in the median part.

In the males the lower antennular flagellum is 11 or 12 segmented; there is 1 clasping spine which is thick with a row of 8-15 large teeth; the first segment of the main branch has, in addition to a swelling, 1 marginal spinule and 3 basal spinules; the segment opposite the clasping spine bears 4-6, mostly 5, spinules of which the distal one is often short. In the petasma the capitulum carries 2 falcate hooks; the distal hook is smaller than the proximal one; there are a few minute hooks on the end of the capitulum. The appendix masculina has 4-5 hooks on the distal margin.

In both females and males there is a small round projection between the first pleopods, but it is not procurved as in Acetes erythraeus. There is 1 red spot on the endopod of uropod.
