description: DELAMARELLA GALATEAE COTTARELLI, 1971   
Originally described from Sardinia (Cottarelli, 1971), the species has now also been found on mainland Italy (Sorrento area).  
 Type locality: Italy, Sardinia, north coast, beach near mouth of Rio de li Saldi, 200 m upstream.   
 Material examined: (1) From type locality: 1 ♀ dissected on slide; leg. V. Cottarelli, 25 February 1999; deposited in NHM, reg. no. 2005.186; (2) south of Salerno, mouth of Torrente Asa, near the village of Pontecagnano Faiano: 2 ♀♀ on slide, 1 ♀ and 1 ♂ on slide, 4 ♂♂ each on 1 slide; all specimens mounted in toto; leg. V. Cottarelli, 20 November 1972; deposited in NHM, reg. nos. 2005.187–194; (3) several specimens from rivermouth of Rio Posada, Nuoro Province, western Sardinia; leg. V. Cottarelli.   
 Additional observations   
 Female: Anal operculum spinulose, with 7–10 large spinules (Fig. 7B). Caudal ramus with dorsal spinules at inner distal corner and around base of seta VII; the oblique ventral setule row figured by Cottarelli (1971: Tav. I-3, left ramus only) is absent but some fine long setules are present along the inner margin; ventral surface with pore near proximal margin and tube-pore subdistally; ramus with 7 setae as in D. obscura.   
 Antennule clearly 9-segmented; armature formula as in D. obscura.   
 Antenna (Fig. 7C). Basis and proximal endopod segment incompletely separated; abexopodal seta of proximal endopod segment much shorter than that on basis; armature of distal endopod segment as in D. obscura.   
Mandibular endopod with 6 apical setae instead of 5 as figured by Cottarelli (1971: Tav. II-2).  
 Maxillule and maxilla as in D. obscura.   
Maxilliped less slender than figured by Cottarelli (1971: Tav. II-8); basis with additional seta on palmar margin and spinule row on posterior surface; endopodal claw more elongate than in original description.  
P1 exopod 3-segmented; exp-1 and -2 with outer unipinnate spine and covered with coarse spinules around outer and distal margins; exp-3 small, with 2 unipinnate geniculate spines and 2 long bare setae; boundary between exp-2 and -3 not always clearly defined. Endopod 2-segmented; enp-1 with serrate inner seta [overlooked in Cottarelli (1971: Tav. III-1,4)].  
P2–P3 exp-2 with plumose inner seta [overlooked in Cottarelli (1971: Tav. III-2,6)].  
 P1–P4 armature formula and detailed morphology of P5 as in D. obscura.   
 Male: Caudal rami with large cup-shaped pore ventrally halfway along ramus length.   
 Antennule haplocer with 5 segments distal to geniculation; indistinctly 13-segmented; boundaries between segments 11 and 13 expressed only dorsally, completely fused ventrally. Segment 5 small, represented by small U-shaped sclerite. Segment 6 with long aesthetasc fused basally to seta. Armature formula as in D. obscura.   
 P4 closely resembling condition in D. obscura but distal seta on exp-3 shorter.   
 P5 (Fig. 7E) essentially as in D. obscura except that exopodal spines are longer and more slender, and middle endopodal spine has long spinules instead of being denticulate.   
Sixth pair of legs strongly asymmetrical, with both members fused to genital somite and bearing 1 short bare and 1 long plumose seta; largest member functional one, inner portion rounded and with denticulate free margin.
