Tanapseudes gutui Hansknecht et al., 2002  

( Figs 102–104)

Tanapseudes gutui Hansknecht et al., 2002: 67   , Figs. 2–3. Guţu and Angsupanich, 2005: 51, 52, 55.

Type material. Holotype: adult male ( USNM 1001787 View Materials )   . Paratypes: 2 males, 1 ovigerous female ( USNM 1001788 View Materials )   ; 1 male, 1 ovigerous female ( GCRL 2038 View Materials )   ; 1 male ( MHN Grigore Antipa No. 250.181); 2 ovigerous females ( MHN Grigore Antipa No. 250.180)   ; 1 male ( NHM 2001.6903)   ; 1 female ( NHM 2001.6904)   .

Material examined. Paratypes: 1 ovigerous female, 1 adult male, GCRL 2038, CH2MHill Consultants, Carolina WWTP, Puerto Rico, San Juan Estuary, 18°27.797N, 65°53.439W, St. Cl –2, 34m, sandy clay, Oct. 30, 1999. Non –types GoogleMaps   : 1 adult male, EPA Coastal 2000, 6701, St. PR 44, Puerto Rico, id. Tom Hansknecht   ; 3 males, 1 female and 2 juveniles, MAFLA station 2426, 28°57´N 85°23´W, 82 m, fine sand, coll. 1977.

Diagnosis. Pleonites with only few (three at most) lateral plumose setae. Pleotelson with very pronounced rounded posterior protuberance. Male pereopod 1 with dorsodistal spiniform seta on propodus reduced or lacking. Male cheliped carpus with ventrodistal rounded protuberance. Pereopods 2–5 with ventral margins of merus and carpus heavily setose. Uropod basal article lacking inner distal spiniform projection.

Type locality. San Juan , Puerto Rico, 18°27.797'N 65°53.439'W, 3–34 m depth ( Fig. 100) GoogleMaps   .

Geographic distribution. Northwestern Atlantic, Caribbean Sea ( Puerto Rico, Tobago) and eastern Gulf of Mexico, 3–82 m depth (Fig. 1, number 44; Fig. 100).

Remarks. Hansknecht et al. (2002) described and illustrated the uropod exopodite of T. gutui   as being biarticulate. However, examination of type material revealed the presence of three articles (1 small round basal article, Fig. 103F). They also mention that the adult male cheliped has a tooth midway on the cutting edge of the dactylus; we did not see this tooth on the paratype male we examined ( Figs. 102F, G).

Tanapseudes gutui   can be distinguished from the other congeners by having the male pereopod 1 propodus with a reduced dorsodistal spiniform seta ( Fig. 103A) and the male cheliped with a carpal process ( Fig. 102F). Guţu and Angsupanich (2005) describe this pattern in specimens collected from the Andaman Sea in Thailand to which they attribute to T. ormuzana   . Their specimens are likely to represent a new species because these characteristics were not evident in the material examined by me, Hansknecht et al. (2002) or in the original description ( Băcescu, 1978). The location of their material is also distant from the type locality. The posterior protuberance of the pleotelson of T. gutui   ( Figs. 102A, B) also seems to be more pronounced and pereopods 2–5 ( Figs. 103B–D) more setose than in the other species.

The range of T. gutui   was expanded northward into the eastern Gulf of Mexico ( Drumm and Heard, 2010) based on examination of new material.

Tanapseudes sinensis Bamber, 2000: 45   , Figs. 4–6. Guţu, 2001: 68, 69. Hansknecht et al., 2002: 67–70.

Material examined. Non– types: near type locality, Persian Gulf, 26°26'N, 52°17'E, 70 m, July, 2005, coll. and det.: R. Bamber.

Diagnosis. Pleonites with several lateral plumose setae. Pleotelson with rounded posterior protuberance. Male pereopod 1 with long dorsodistal spiniform seta on propodus. Male cheliped carpus lacking ventrodistal rounded protuberance. Pereopods 2–5 with ventral margins of merus and carpus not heavily setose. Uropod basal article lacking inner distal spiniform projection.

Type locality. Ormuz Straits , Indian Ocean, 26°31'7"N 56°42'5"E, 10–67 m depth ( Fig. 100) GoogleMaps   .

Geographic distribution. Indian Ocean (Red Sea, Persian Gulf), 10–70 m depth (Fig. 1, number 45; Fig. 100).

Remarks. Tanapseudes ormuzana   can be distinguished from the other two congeners by a combination of characters including: 1) male cheliped lacking carpal process ( Fig. 108A), 2) male pereopod 1 propodus with a long dorsodistal spiniform seta ( Fig. 108B) and 3) uropod basal article lacking an inner distal spiniform projection ( Fig. 107D). As mentioned above in the “remarks” section for T. gutui, Guţu and Angsupanich (2005)   partially redescribed T. ormuzana   from material collected in the Andaman Sea, which is geographically fairly distant from the type locality. We believe it might represent a new species because their description did not match the original description ( Băcescu, 1978) in several key characteristics such as the male cheliped and pereopod 1. It seems to be more similar to T. gutui   .

Băcescu (1978) described the male cheliped as having a large notch in the carpus, but this is actually the space between the merus and carpus (mentioned in Hansknecht et al., 2002). Tanapseudes ormuzana   was apparently discovered in the Red Sea ( Makkaveeva, 1971) but material is unavailable for examination.
