Platytyphlops latus (Hale, 1946) n. comb.

Hemilamprops lata Hale, 1946: 179–183, figs 1–2.

Type material. Holotype: SAMA 2802, female . Allotype: SAMA 2804, male. 11 miles off Eden, New South Wales, Australia .

Diagnosis. Carapace with 1 pair dorsal partial ridges, many incomplete ridges, marginal carina entire, ridge present on pseudorostrum; eyelobe with lenses or tumidities; pseudorostrum excavate. Antennule article 1 not expanded; accessory flagellum equal to main flagellum. Telson 0.8 uropod peduncles, with 3 terminal setae, terminal setae equal. Uropod endopod article 1 1.1 length of articles 2 and 3 together. Adult male carapace less sculptured than in female, antenna extending to posterior border of pleonite 5.

Depth. 50–120 m.

Distribution. Australia: New South Wales, Tasmania.

Remarks. This species is similar to Platytyphlops mawsoni, but can be differentiated by size, being much smaller than P. mawsoni, and having an excavate pseudorostrum in dorsal view, while in P. mawsoni the pseudorostrum projects anteriorly and comes to a point. The species is transferred to Platytyphlops because of the presence of the marginal carina on the carapace, the presence of two setae on the maxillule palp, and the proportions of the uropods, with uropod endopod article 1 longer than articles 2 and 3 together, and the uropod exopod with the first article much less than half the length of article 2. The combination of the carapace morphology and uropod exopod proportions mean that this species does not fit within Hemilamprops .
