Superfamily LASIODISCOIDEA Reitlinger, 1956 View in CoL Description. See Fig. 1 View Fig .

Family HOWCHINIIDAE Martini & Zaninetti, 1988 Tests free, consisting of an undivided tubular chamber, helicoidally coiled in a spire high to low conical. Depressed umbilical region empty ( Vissariotaxis ) or occupied by a hyaline plug, corresponding possibly to anastomosed pseudopillars ( Howchinia Cushman, 1927 ; Monotaxinoides Brazhnikova & Yartseva, 1956 ; Planohowchinia Cózar & Mamet, 2001 ). Spiral sutures depressed, without or with small appendices. Aperture terminal simple at the extremity of the tubular chamber; supplementary sutural apertures are present. Middle Visean (MFZ12)–Moscovian.

Remark: Vissariotaxis Mamet, 1970 with its single layered microgranular wall is a transitional form from the Pseudoammodiscidae to the Howchiniidae and is rattached to its derived descendant group.

Composition: Howchinia Cushman, 1927 ; Monotaxinoides Brazhnikova & Yartseva, 1956 ; Planohowchinia Cózar & Mamet, 2001 ; Vissariotaxis Mamet, 1970 .
