Figures

Planche 1 issued from : O. Tanaka in Publs Seto Mar. Biol. Lab., 1964, XII (1). [p.91, Fig.219]. As Pachyptilus eurygnathus.
Female: a, habitus (dorsal); b, forehead (left lateral side); c, last thoracic segment and urosome (left lateral side); d, masticatory edge of Md; e, P1; f, P5.
Nota: The urosome segments and furca are in the proportional lengths as 55:9:6:12:18 = 100. The furcal rami as long as wide. A1 exceeds the end of the furca by distal 5 segments.

Species Pseudhaloptilus eurygnathus - Planche 4 of morphological figures

Planche 4 issued from : R.B.S. Sewell in The John Murray Expedition, 1933-34, Scientific Reports, VIII (1), 1947. [p.166, Fig.44, I]. As Pachyptilus eurygnathus.
Process on the posterior aspect of the 2nd basal segment of P1.
Remarks: The shape of the hook-like or spine-like process shows some variation in different genera, but it is undoubtedly homologous throughout the whole series. The function of this organ is unknown.

Remarques

méso-bathypélagique;
Boxshall & Halsey, 2004 (p.68), s'appuyant sur un travail de Soh (1998, non publié), considèrent que Pachyptilus est synonyme junior de Pseudhaloptilus.
