RV Hakuhō Maru KH-72-1 cruise, sta. 29, 1Ə ( CB 3.6×CL 4.7 mm ), NSMT-Cr 30709; 2 ƏƏ (2.9× 3.7 mm ; 3.5× 4.2 mm ), 2♀♀ (2.9× 3.5 mm ; 3.5× 4.0 mm), 4 ovig. ♀♀ (3.0× 3.8 mm – 4.5× 5.3mm ), NSMT-Cr 30710. Remarks. This short-neck species, Achaeus paradicei ( Fig. 5C ), was first mentioned as Achaeus sp. in the key to the New Zealand and Australian species of Achaeus (Griffin and Yaldwyn, 1965) and later, listed also in the keys by Griffin (1966b , c). However, this species is formally known by the original description (Griffin, 1970) and the subsequent description by Griffin and Tranter (1986) , with accounts of interspecific variation. All the chelipeds and ambulatory legs are missing in three male specimens at hand, but the carapace shape and granulation ( Fig. 5C ) agree generally with the preceding descriptions, although with some variations. The rostral lobes are blunt and spinulous along the margins, and the median incision is narrower than the original figure. The carapace was mentioned by Griffin and Tranter (1986: 13) as having "two to four spines on the margin of the hepatic region, sometimes the spines are bifid or spinulous," and illustrated as such. In the males at hand the hepatic lobe is well developed and armed with a subsidiary, prominent but slightly smaller tubercle than the main one on the anterior slope. The branchial region is said by Griffin and Tranter (1986) that three to five spines anterior on the submargin are small in females, but much more pronounced and visible dorsally in males. Three tubercles on the branchial margin were figured in the original description and visible in the male at hand. Distribution .
