Eohypochthonius Jacot, 1938

Eohypochthonius Jacot, 1938b, p. 133.

Jacot founded the present genus on Hypochthonius gracilis, a species described by him in 1936c (p. 251, pl. 20 fig. 9) from North Carolina (U.S.A.). The genus distinctly belongs to the Hypochthoniidae but differs from Hypochthonius among others by the transversely divided genital covers.

Judging from Jacot's description, E. gracilis is much smaller and slenderer than Hypochthonius rufulus; the notogastral hairs are longer (c2 is nearly as long as c1); according to the figure e1 and e2 are virtual 1).

1) Grandjean characterizes a hair as "virtuel" when the place of insertion only is present.

In my opinion the following species must be added to the genus.

Eohypochthonius asiaticus (Berlese, 1910).
