Aristov, Daniil S. & Storozhenko, Sergey Yu., 2011, Review of the Permian family Permulidae nomen novum pro Aliculidae Storozhenko, 1997 (Grylloblattida), ZooKeys 130, pp. 111-130 : 112

Family Permulidae Aristov & Storozhenko nom. n.

Type genus.

Permula Handlirsch 1919.

Aliculidae Storozhenko, 1997: 8 (type genus: Alicula Schlechtendal, 1913); Storozhenko 1998: 97. Invalid name according to Article 39 of the Code (ICZN, 1999).

Diagnosis.

In Permulidae CuA is either simple or branching distal of its middle and CuA2 not individualized. In other families of the order Grylloblattida either the first fork of CuA is situated near the base, or CuA1 and CuA2 are well individualized.

Description.

Medium-sized insects. Forewing uncolored, without spots and stripes. Costal area narrow to broad. SC ending near the apical third of wing or apically. RS originates in basal third or quarter of wing. The base of M and CuA distinctly separated or fused. M forked distinctly before or near the base of RS. MA simple or branched. MP desclerotized near the middle of wing. M5 not individualized. CuA not divided into CuA1 and CuA2, CuA is branched distal of its middle, with 2-4 branches, distal branches of CuA not parallel to posterior margin of wing, rare CuA simple. CuP simple, straight or gently curved. A1 simple. Cross-veins either simple or forming two or more rows of cells in the majority of areas. Hind wing similar to forewing but anal area enlarged. Body unknown.

Composition.

Seven genera are known from the Permian of Europe and North America, two of them are described as new below.

Notes.

The generic name Alicula Schlechtendal, 1913 (Insecta) is a junior homonym of Alicula Eichwald, 1830 (Mollusca). The name Alicula Schlechtendal, 1913 must be replaced by Permula Handlirsch 1919 (the next oldest available name from among its synonyms). Thus, the family name Aliculidae Storozhenko, 1997 must be replaced by a new replacement name Permulidae based on the valid name of the former type genus according to Article 39 of the Code (ICZN, 1999).
