Cryptazeca is agenus of snails from the family of Azecidae in the suborder of land snails (Stylommatophora).

features

The egg-shaped housing is 3 to 4 mm high and 1.4 to 1.6 mm wide. It has up to six turns that are strongly flattened on the periphery. The apex is rounded and blunt. The case surface is smooth and appears polished. The color varies little from almost colorless to yellowish. The mouth is egg-shaped with a slightly thickened edge of the mouth. The parietal wall is toothless, the spindle wall is provided with a small tubercle.

In the genital system, the egg ladder is unusually short. The long sperm duct branches off high up. It enters the very short, thick-walled epiphallus apically. This penetrates laterally into the elongated egg-shaped penis. The inner surface of the penis has numerous papillae, on each of which there is a pointed, curved, conchin-like spine. The retractor muscle attaches apically to the penis. The free fallopian tube is very long and the vagina is significantly shorter. This is swollen with a glandular wall (perivaginal gland). The inner surface of the lower part of the free fallopian tube and the vagina is studded with thorns. The comparatively short stalk of the spermathec is strongly thickened at the base, the bladder does not extend to the albumin gland.

Geographical distribution

The few species in the genus are restricted to the western and northern parts of the Iberian Peninsula. Some species are cave dwellers.

Taxonomy

The taxon was established in 1877 by Alexandre Guillaume Léopold Marquis de Folin and Ferdinand Bérillon . The type species is Azeca monodonta Folin & Bérillon, 1877. The genus Cryptazeca is the type genus of the (sub) family Cryptazecidae Schileyko, 1998, which is, however, a more recent synonym of Azecidae. The following species are currently included in the genus Cryptazeca :

The fauna Europaea lists the genus Cryptazeca under the family Ferussaciidae , subfamily Cryptazecinae.

Individual evidence

  1. ↑ The co-author of Alexandre Guillaume Léopold Marquis de Folin appears in only a few publications mostly without a first name as M. Bérillon. The M. stands for monsieur. Welter-Schultes leads him with E. Bérillon and suspects an identity with Edgar Bérillon, a French psychologist. Madeira et al. (2010) perform him with G. Bérillon, while Gittenberger & Kosten (1983 ) perform as F. Bérillon. In the membership lists and meeting reports of the Société des sciences et arts de Bayonne , this co-author almost always appears as Bérillon or M. Bérillon . In the list of members of the Society of January 1, 1877 , he is referred to as photographe à Bayonne . He is certainly not identical with Edgar Bérillon. The artist directory of the Musée d'Orsay includes the photographer Ferdinand Bérillon , who was active in Bayonne from 1863 to 1890. He is the sought-after co-author of the Marquis de Folin.
