Genus Apseudomorpha Miller, 1940

Type-species. Apseudomorpha oahuensis Miller, 1940 .

Species. Apseudomorpha albida ( Shiino, 1951) ; A. avicularia ( Barnard, 1914) ; A. drummi sp. nov.; A. fontainei Guţu, 1987 ; A. glebosa ( Menzies, 1953) ; A. hirsuta ( Stebbing, 1910) ; A. magdalenensis ( Menzies, 1953) ; A. martinicana Guţu, 2009 ; A. negoescuae Guţu, 2007 ; A. oahuensis Miller, 1940 ; A. ortizi Guţu, 2006 ; A. timaruvia ( Chilton, 1882) ; A. veleronis ( Menzies, 1953) ; A. vestafricana Guţu, 2006 .

Diagnosis. (modified from Guţu 2006). Body subcylindrical. Carapace usually with short and denticulate rostrum; ocular lobes well-developed containing visual elements. Pereonites wider than long. Pleon distinctly narrower than pereon, with five unfused, short, pleonites; pleotelson short, subcylindrical. Antennule biramous, usually shorter than cephalothorax; peduncle having one or more spiniform apophyses on inner margin of article-1; article-2 longer than article-3. Antenna with small squama. Mandible having thick palp with articles. Maxillule with palp having two articles. Cheliped and pereopod-1 lacking exopod. Cheliped sexually dimorphic; male strongly developed and subequal in size, basis appearing sub-ovoid, carpus stout and short, propodus and dactylus forming large chela; female having cheliped distinctly smaller and less robust than male, carpus narrow. Pereopod-1 subcylindrical, slightly large and generally similar to pereopods 2–3. Pleopods absent or reduced in size, when present (up to five pairs), uniramous or biramous. Uropods with short biramous rami

Remarks. Within the subfamily Metapseudinae , Apseudomorpha can be distinguished from the superficially similar genera Julmarichardia Guţu, 1989 , Pseudoapseudomorpha Guţu, 1991 , and Plectrocopus Guţu, 2006 ) by the absence of an exopod on the cheliped.
