Male

General description ( Figures 1B, 4A View Figure 4 ). Colour light, nearly white to ivory with orange ornamentation on dorsal surface of carapace, chelipeds and walking legs. Carapace rounded, dorsally very convex, strongly calcified, not translucent, without defined regions and lateral teeth. Surface plain and smooth owing to lack of setae. Front very pronounced, slightly acuminated in middle. Eyes clearly visible in dorsal view, with light orange colouration in living specimens.

Chelipeds (P1), relative length of articles of walking legs and third maxillipeds consistent with description of female given below, but chelipeds generally much stronger and stouter than in adult females.

Second and third pair of walking legs (P3, P4) with swimming fringes: two rows of long pappose setae on distal articles. One running dorso-posteriorly on carpus and propodus, one ventro-anteriorly. Shorter pappose setae lining dorsal and ventral margins of all walking legs (P2–P5).

Largest males, found in Pinna nobilis   , with carapace width of about 7 mm.

Pleon (abdomen) and sternum ( Figure 4B View Figure 4 ). Male abdominal segments clearly separated. Belonging to Thoracotremata, male gonopores on sternum. Pleon narrow, general shape triangular. Pleon tapering distally from segment 3 to segment 6, lateral margins of segment 3 slightly rounded, shape of segment 4 and 5 trapezoid, margins of segment 6 slightly rounded, shape of telson trapezoid.

Whole outer margin of pleon setose, remaining surface smooth.

First gonopod ( GP 1) ( Figure 4C, D View Figure 4 ). GP 1 straight over almost total length, strongly flattened dorso-ventrally. Distal part narrowed abruptly with light curve in last 7/8. Distal openings of ejaculatory canal oriented slightly towards lateral side of body. Gonopods with long pappose setae on proximal base and along total length, setae more numerous in curve of distal part.

Female (adult)

General description ( Figure 1A, C, 5A View Figure 5 ). Colour light ivory, nearly white. Carapace subglobular or slightly wider than long, especially in large females. Carapace very soft, translucent through decalcification, without defined regions and lateral teeth. Eyes hardly visible in dorsal view, especially in large females. Eyes of living specimen with light orange colouration. Carapace and whole body surface smooth, shiny owing to lack of setae. Pleon very broad, rounded, covering whole ventral side including coxae, reaching front anteriorly. Pleons’ margin setose, outer surface smooth.

Maximum body size of adult (ovigerous) females about 18 mm in carapace width in specimen from Pinna nobilis   , minimum about 4 mm in small ovigerous females inhabiting Mytilus edulis   .

Juvenile females consistent with the description of males (except for pleopods).

Chelipeds and walking legs ( Figure 5A, B View Figure 5 ). Cheliped (P1), especially palm, slender in adult females (stouter in juvenile females and males). Cutting edge of claw with one single pointed tooth on movable finger (dactylus) and one single tooth on fixed finger (propodus). Inner and outer surface of palm rather smooth, only scattered setae. Simple and plumose setae located near angle of propodus and dactylus and on cutting edge of claw. Field of long pappo-serrate setae forming dense comb on bottom side of claw.

Walking legs (P2–P5) with short, pointed, curved dactyli. Dactyli of P2–P5 considerably less than half as long as propodus. Dactyli almost of equal length in all walking legs. Swimming fringes of second and third walking legs (P3, P4) present in juvenile females, reduced in adults.

Third maxilliped ( Figure 5C View Figure 5 ). Third maxilliped with large completely fused merusischium-article. Dactylus of palp inserting underneath propodus (subterminally). Flagellum two-segmented with tuft of long simple setae originating from tip. Third maxillipeds’ inner margins densely fringed with long simple setae, surfaces of merusischium, carpus and propodus smooth.

Comments

In contrast to data in the literature ( Schmitt et al. 1973), we found Pinnotheres pisum   exclusively in bivalves, but never in ascidians.
