Heterocarpoides de Man. 



Heterocarpoides nov. subg. J. G. de Man, in: Zoologische Mededeelingen, uitgegeven vanwege 

 's Rijks Museum van Natuurlijke Historie te Leiden, Deel III, Afl. 4, December 1917, p. 284. 



It appears rather beyond a doubt that Dorodotes levicarina Bate, a species found in 

 the Arafura Sea, south of Papua, has originally been referred by Spence Bate to the genus 

 Heterocarpus A. M.-Ed\v. and that, owing to an incomprehensible mistake and error, it has 

 afterwards been described by him as a species of the genus Dorodotes. In the first place the 

 description of this genus on p. 677 of the Report on the Challenger Macrura is only applicable 

 to Dor. reflexies Bate, but not to Dor. levicarina, because both carapace and abdomen are 

 described as smooth, i. e. non carinate, and the ophthalmopod as small and uniarticulate, 

 while in Dor. levicarina carapace and abdomen are carinate and the eyestalk resembles that 

 of the genus Heterocarpus \ in the second place the author remarks at the end of the page 

 "I only know of one species of this genus etc", furthermore we read in his description of 

 Dor. levicarina (p. 681) "the dorsal carina is likewise less conspicuous than in the typical 

 forms of the genus", where the word "forms" can only refer to the numerous species of the 

 genus Heterocarpus and, finally, Dor. levicarina has been figured on the same plate with the 

 other species of that genus. Dorodotes levicarina indeed in all characters agrees with the 

 genus Heterocarpus, excepting only the legs of the second pair, which are equal and only 

 composed of six joints, the i st of which is nearly as long as the following together, the 2 nd — 5 th , 

 however, very short and equal ; it differs, moreover, from all known species of the genus 

 Heterocarpus by the characteristic carination of the carapace, the post-antennular carina running 

 uninterruptedly from near the posterior margin to the orbital spine, the post-antennal carina 

 wanting entirely, while of the post-ocular carina only the posterior half is developed, that curves 

 downward and unites with the post-antennular on the hepatic region. It agrees therefore both 

 with Hetcroc. ensifer A. M.-Edw. and Heteroc. Wood-masoni Alcock in the possession of the 

 post-antennular carina, but it differs from the former by the suppression of the post-antennal 

 and from the latter by the posterior half of the post-ocular carina being developed; like in 

 Heteroc. ensifer the post-ocular carina curves also downward towards the post-antennular. 



The subgenus Heterocarpoides is therefore proposed for this species.
