Chondrina pseudavenacea spec. nov. (pl. 13 fig. H)

Type series: Spain, Alicante. — 7 km NE of Altea, Barranco de Mascarat, UTM YH6080 , L. Gasull leg. ( RMNH 109867 / holotype) ; 7 km NE of Altea, Barranco de Mascarat , UTM YH6080 , L. Gasull leg. ( RMNH 111888 / 54 paratypes) ; Morro de Toix , S-side peninsula, c. 250 m alt., UTM BC4079 , BC leg., 6.v.2006 ( RMNH 109868 / 15 paratypes); 2 km ESE Callosa de Ensarria, near cascada El Argar , UTM YH5281 , L. Gasull leg. ( RMNH 109869 / 1 paratype) ; 2 km ESE Callosa de Ensarria, near cascada El Argar , UTM YH5281 , H.B. Marcus leg. ( RMNH 111887 / 6 paratypes) .

Description.—Shell brownish, conical or somewhat more fusiform, with fine, more or less obsolete growth-lines, which do not give the impression of regular riblets. Aperture with three prominent palatals, of which the infrapalatalis is the weakest, a columellaris and a less conspicuous infracolumellaris, and a very prominent parietalis. An angularis is more or less obsolete or lacking completely and a spiralis is always absent. Shell height 5.8–6.8 mm; width 2.7–3.0 mm.

Notes.—This Chondrina species can be recognized relatively easily on the basis of only shell characters. In C. avenacea , which is somewhat similar conchologically, the shell is more cylindrical instead of conical, and always has a spiralis in the aperture.At the three localities from where it is known, this species occurs together with C. arigonis , which can easily be distinguished by the presence of only two palatal teeth and a more conspicuously thickened and flattened apertural lip.

Derivatio nominis.—The epithet refers to the similarity with C. avenacea in apertural characters.
