Material examined. Honduras: 1 male, 1 ov. female, OUMNH. ZC.2007-20-104, Utila, Jack O'Neill Cove, 16º04.574'N 86º56.403'W, in orange sponge (possibly Lissodendoryx sp. ), 15 m, coll. A. Anker & S. De Grave GoogleMaps ,

04.07.2007 [fcn H146*]. Brazil: 1 male, UFC 439 View Materials , Ceará, locality not specified (“litoral do estado do Ceará ”), 35–40 m, coll. “Barco SWJ” , 24.11.1972.

Description. For full description and illustrations see Coutière (1909), Dardeau (1984), and Ríos & Duffy (2007).

Size range. Specimens from Honduras: male, 5.0 mm cl, female, 5.9 mm cl; male from Ceará ( Brazil), 4.0 mm cl; specimens from Carrie Bow Cay ranged 4.3–6.6 mm cl for males and 6.0– 6.8 mm cl for females ( Ríos & Duffy 2007).

Colour in life. Semitransparent or pale reddish-orange, uniformly speckled with small red chromatophores; major chela fingers darker brown-orange; ovaries or freshly laid eggs reddish ( Fig. 41 View FIGURE 41 ); see also colour photograph in Ríos & Duffy (2007: pl. 4).

Type locality. St. Thomas , US Virgin Islands .

Distribution. Western Atlantic: Gulf of Mexico [West Flower Garden Bank, Isla de Lobos]; Florida [Key Largo, Tortugas, Bright Bank, Florida Middle Ground]; Bahamas [Cay Sal Bank]; Caribbean Sea: Cuba (Batabanó Gulf], Honduras [Utila], Panama [Bocas del Toro], Puerto Rico, US Virgin Islands [ St Thomas, St. John], British Virgin Islands [ Tortola, Guana, Virgin Gorda], Venezuela [Los Roques Achipelago], Curaçao, Barbados; Brazil: Ceará ( Coutière 1909; Zimmer 1913; Schmitt 1935; Chace 1972; Dardeau 1984; Rodríguez 1986; Ríos & Duffy 2007; present study; K. Hultgren, pers. obs.; see map in Fig. 52 View FIGURE 52 ); some of these records may refer to closely related species (see below).

Ecology. Shallow reef and adjacent rubble and sand flats with abundance of sponges; typical depth range in the Caribbean-Florida area: 1–15 m, possibly deeper in Brazil: 35–40 m; obligate symbiont of demosponges, e.g., Lissodendoryx cf. strongylata , L. colombiensis , Agelas clathrodes , Hyattella intestinalis and Hymeniacidon amphilecta ( Ríos & Duffy 2007) ; typically in heterosexual pairs.

Remarks. Many records of S. pandionis prior to Ríos & Duffy’s (2007) revision of the S. longicarpus species complex possibly refer to the closely related S. ul, S. yano and S. dardeaui . Synalpheus pandionis differs from these species by the presence of a relatively small but conspicuous bump on the mesial side (not lateral side, error in Ríos & Duffy 2007) of the major chela pollex, best visible in ventral view of the major chela (see Ríos & Duffy 2007: fig. 24F). Ríos & Duffy (2007) discussed the synonymy of S. grampusi Coutière, 1909 and S. pandionis extentus Coutière, 1909 with S. pandionis , which is followed herein.

The single specimen from Ceará represents the first record of S. pandionis for Brazil, considerably extending the previously known range of this species, from Florida, Gulf of Mexico and the Caribbean Sea ( Ríos & Duffy 2007) to northeastern Brazil (see map in Fig. 52 View FIGURE 52 ). The Brazilian specimen corresponds closely to S. pandionis as illustrated by Coutière (1909), Dardeau (1984), and Ríos & Duffy (2007), including the presence of the diagnostic mesial protuberance on the major chela.
