Genus Archaemegaptilus Meunier 
Archaemegaptilus Meunier, 1908: 155; Meunier, 1908: 175; Meunier, 1909: 
138; Handlirsch, 1919: 13; Lameere, 1917: 103; Lameere, 1917: 160. 
Type species: Arachaemegaptilus kiefferi Meunier, 1908 (OD). 
This genus is monotypic, based by Meunier on the reverse of a 
hind wing. As Lameere (1917, p. 160) correctly noted, the obverse 
specimen, which was apparently not seen by Meunier, is more nearly 
complete; it is figured here for the first time. The following ac- 
count is based on both parts of the type specimen. 
Hind wing: long, broadening basally. Precostal strip pronounced, 
broadened at the base to form a narrow precostal area; Sc slightly 
shortened, terminating by a fork on C and R; stems of R and M 
touching for a long distance just beyond the base; CuA simple, 
curved, not approaching the stem of M ; CuP with several branches 
occupying a large area. Cross venation coarse, consising of cross 
veins connected by anastomoses, becoming a network. Intercalary 
sectors short. 
Archaemegaptilus differs from Dictyoneurella by its longer Sc 
and denser cross venation. 
Species included in the Commentry shales: Archaemegaptilus 
kiefferi Meunier, 1908.

Archaemegaptilus kiefferi Meunier, 1908: 155; Meunier, 1908: 175, fig. 3; 
Meunier, 1909: 138, pi. 2 fig. 2; Handlirsch, 1919: 13, fig. 15. 
Although this species was erected by Meunier on a fragment of 
the reverse of a hind wing, the following account is based on the 
obverse as well. 
Hind wing: length 105 mm, width 27 mm. Anterior margin 
straight, slightly concave near the base, separating off a narrow 
precostal area. Wing broadened in the middle part of its length, 
narrowing behind the CuA area. Apex directed backward, rounded; 
C, Sc and Cu covered by long hairs near the base. M touching the 
stem of R, near the base, but diverging from it again; r-rs area 
somewhat broadened, with oblique cross veins; Rs with 3 branches, 
first of them forking twice; MA originating near the first fork of 
MP; MP forked 5 times; CuP with 4 branches. Color marking 
in the form of small light spots. 
Archaemegaptilus kiefferi shows very similar color patterns to 
Dictyoptilus sepultus (Eugereonidae) and to Moravia convergens 
Kukalova (hind wing, Calvertiellidae) . Dictyoneurella perfecta
