GENUS DUGASTELLA BOUVIER, 1912

Synonymy: Atyaephyra F. de Brito Capello p.p.

Diagnosis: Paratyine genus with supraorbital and suborbital spines, and with a pterygostomial carapace border jutting out (pterygostomial spine); dorsal rostral denticulation not continued posteriorly on carapace; maxilliped I exopodital lobe gradually narrowed distally, with terminal flagellum as long as width of lobe; pereopods I–III or more with exopodites; mature male pereopods III–IV not distally widened, dactylus not pectinate; pereopod-V dactylus comb-like; male pleopod-I endopodite short, ribbonshaped, with parallel side borders, part of distal border extended into comparatively wide AI, which is approximately twice as long as it is wide; male pleopod II with sausage-shaped AM, which is set in the distal half with long straight spines (longer than AM diameter), moderately longer than AI. Known species are epigean with normal eyes.

Type species: Dugastella marocana Bouvier, 1912 , with type locality: Morocco, spring in Settat .

Other species: Atyaephyra valentina Ferrer Galdiano, 1924 .

DUGASTELLA VALENTINA ( FERRER GALDIANO, 1924)

( FIGS 2 Dv, 4Dv, 5Dv)

Synonymy: Atyaephyra valentina Ferrer Galdiano, 1924 .

Type locality: Spain, prov. Valencia, Mijares River in Xuquer basin .

Material examined: Spain, Valencia, Baldovi, leg. F. Mezquita Juanes. Sequenced and dissected specimens ‘02-Dug=V64’, ‘03-Dug=V65’, and only dissected ‘01-Dug’.

Diagnosis: An Iberian Dugastella species. No detailed morphological (or molecular) comparison with type species could be accomplished.

Remarks: The Spanish species seems to be morphologically so similar to the Moroccan type species that they are likely to belong to the same clade, but a molecular confirmation is still lacking. The closest, but still comparatively loose relationship, of the Spanish D. valentina with European cave shrimps has been established molecularly.

The locality of our sample of D. valentina is Baldovi, about 45 km to the south-east of the type locality. Hydrography of the region and presence of these shrimps in vegetation along channels (F. Mezquita, pers. comm.) suggests probable gene flow and continuity of the population. Therefore, the molecular data is considered to be representative for this taxon here.

Distribution: Surface waters of Valencia ( Spain).
