Description ( Fig. 17 View Fig )
Living animal of dark green colour. Body of oval shape ( Fig. 17A,B View Fig ). Legs robust, 3.5× as long as trunk. Proboscis short, with blunt tip ( Fig. 17B View Fig ). Body segments with well developed margins. ( Fig. 17B View Fig ). Eye tubercle flat, with 4 dark-pigmented eyes. Abdomen short. Chelifores of same length as proboscis, chelae in front of mouth ( Fig. 17A View Fig ). 2 small teeth on inner finger ( Fig. 17F View Fig ). Palps absent as well as ovigera in female specimen.
Coxa 1 with 2 to 3 small setae located distally, and a mediodistal small groove ( Fig. 17A,B View Fig ). Coxa 2 almost 2× as long as coxa 1, also with small distal bristles. Coxa 3 of same length as coxa 1 ( Fig. 17A,B View Fig ). Femur slightly swollen, no eggs visible ( Fig. 17C View Fig ). Femur 2× as long as coxa 2. Thin distal spine present ( Fig. 17C View Fig ).Tibia 1 slightly wider and longer than tibia 2. Both tibiae with short distal spine ( Fig. 17C View Fig ).Tarsus longer than wide; at its dorsal side a short seta is inserted. Ventral side with several setae ( Fig. 17D,E View Fig ). Heel with 1 spine on 1st leg, 2 spines on 2nd and 4th leg, and 3 spines on 3rd leg ( Fig. 17D,E View Fig ). Two setae of equal length at the heel’ s bases. Sole made of a median row of thick spines and 2 lateral rows of shorter and thinner setae ( Fig. 17D,E View Fig ). Main claw 0.75× as long as propodus ( Fig. 17D View Fig ).
Remarks. It was not possible to determine this pycnogonid since it differs strongly from A. monotrema due to the segmentation, the varying number of heel spines and the 2 setae at the heel’ s base. On the other hand, the studied individual also differs from A. robustus and A. oirecens , the two other Caribbean species our subadult ♀ might belong to: Due to its segmentation our specimen strongly differs from A. robustus , and due to the toothed fingers of the chelae it differs from A. oirescens . In addition, the bristles and the groove on coxa 1 are not mentioned in earlier descriptions. Another very similar species is A. breoirostris from the Philippines. However, the latter species differs from ours in having one further spine on the heel of leg 4.
Hence, our specimen might belong to a previously unknown species closely related to A. monotrema . Since we found only a subadult, single individual, further samples and studies will be necessary to assign this individual to a species.
