Description
Non-ovigerous female (Figs 44, 45, Fig. 46 A and Fig. 47). With general characters of Apseudopsis (Guţu 2006, Esquete et al. 2012 a, Esquete et al. 2012 b, Esquete et al. 2019, Carvalho et al. 2019). Rostrum (Fig. 44 A) short, pointed, with rounded shoulders. Prn 1–6 (Fig. 44 A – C) with posterolateral spiniform apophyses, hyposphenia only present on Prn 6. A 1 (Fig. 44 E) inner flagellum with three art, outer flagellum with seven art. Mouthparts (Fig. 45) as in other Apseudopsis; Md palp (Fig. 45 A) art 2 with two simple setae; Mxp palp (Fig. 45 I) art 1 with two inner distal short spines, endite (Fig. 45 J) with four coupling hooks. P 1 (Fig. 47 A) coxa (Fig. 44 B) projected anteriorly; merus without dorsodistal spines; propodus with six ventral spines. P 3 basis with dorsal proximal spiniform apophysis (Fig. 47 C). Plp 1 (Fig. 47 G) basis with four inner and four outer plumose setae; Plp 2, 3 and 4 with four inner and three outer plumose setae; Plp 5 with three inner and two outer plumose setae.
Male. With general characters for Apseudopsis and same diagnostic characters as female holotype. Ch (Fig. 46 B) carpus without apophyses, propodus without ventral projection, cutting edge with proximal semicircular apophysis, dactylus with invagination. Difference with female: Ch more robust (Fig. 46 B).
Diagnosis
Apseudopsis Norman, 1899 with short, pointed rostrum, six ventral spines on pereopod 1 propodus and all pereonites with posterolateral projections. The only species with a posterior projection proximally on the basis of pereopod 3 in the adults.
Etymology
This species of Apseudopsis was first found in Ria de Ferrol, in Galicia (NW Spain). In Galician, “ da ría ” means “ from the ria ”. Noun in apposition.
Taxon discussion
Previous taxonomic studies revealed that spination and setation of most of the appendages vary intraspecifically according to the size and life stage of the individuals (Esquete et al. 2012 a, Esquete et al. 2012 b) and, hence, are not reliable for identification; therefore, they have been excluded from the description, although they can be consulted in the figures. The characters that allow distinction between species of Apseudopsis, regardless of the life stage of the individuals, are: 1) the shape of the rostrum; 2) the presence and / or position of apophyses on pereonites; 3) the number of hyposphenia on adult females without marsupium; 4) the number of articles on the flagella of the antennula and 5) the number of spines on pereopod 1 propodus (Esquete et al. 2012 b). Additional characters are unique for certain species and typically involve ornamentation on the male cheliped or cephalothorax (Esquete et al. 2012 a, Esquete et al. 2016, Esquete et al. 2019, Carvalho et al. 2019).
Apseudopsis daria sp. nov. has a dorsal spiniform apophysis proximally on pereopod 3 (Fig. 47 C), which is a unique character in the genus. Only three other species of Apseudopsis have six spines on pereopod 1 propodus: A. arguinensis (Guţu, 2002), A. hastifrons (Norman & Stebbing, 1886) and A. isochelatus Guţu, 2006. Apseudopsis arguinensis differs in lacking the posterolateral apophysis on pereonite 1, having short setae on anterolateral corners of pereonites and a hyposphenium on pereonite 2; A. hastifrons has anterolateral apophyses on pereonites 3 to 6, hyposphenia on pereonites 2, 3, 5 and 6 and a proximal row of spinules on the basis of pereopod 5; and A. isochelatus has a long rostrum, no apophyses on pereonite 1, hyposphenia on pereonites 2 to 6, antennule outer flagellum with up to 9 articles and the cheliped in males is as slender as in females. This is the only species of the genus with a proximal spiniform apophysis on pereopod 3; however, this character is very subtle and might have been overlooked in the descriptions of its congeners.
Notes
Methods
Twenty-three specimens were retrieved from two inlets inside the Ría of Ferrol (NW Iberian Peninsula). The bottoms of the ría are mostly sedimentary, composed of mud in the sheltered areas with different proportions of sand. The study sites range from 2 to 13 m in depth and experience an average value of temperature and salinity of 15 ° C and 35 ‰ throughout the year. The salinity values range between 33 and 36 ‰. The inlets are in the middle part of the ría with a small stream mouth in the O Baño inlet. The coordinates delimitating them are the following: Santa Lucía (8 ° 14.4570 ' W, 43 ° 27.8103 ' N; 8 ° 15.0513 ' W, 43 ° 27.8564 ' N; 8 ° 14.9853 ' W, 43 ° 27.6813 ' N; 8 ° 14.5612 ' W, 43 ° 27.6316 ' N) and O Baño (8 ° 15.7487 ' W, 43 ° 27.7495 ' N; 8 ° 16.1401 ' W, 43 ° 27.7661 ' N; 8 ° 16.2372 ' W, 43 ° 27.4804 ' N; 8 ° 16.0011 ' W, 43 ° 27.2739 ' N). Samples were obtained using a Van-Veen grab and sieved through 0.5 mm mesh. The faunal specimens were sorted and fixed in 5 % formaldehyde, rinsed with freshwater and then preserved in 70 % ethanol. Taxonomic treatment and terminology followed Błażewicz-Paszkowycz and Bamber (2007) and Esquete and Cunha (2017). The type material is deposited at the Museo Nacional de Ciencias Naturales, Madrid (MNCN), while other material at the Biological Research Collection of the Biology Department of the Universidade de Aveiro (DBUA).
