2004 Heterostegina reticulata hungarica ssp. nov.; Less and Gyalog

2004: pl. (black and white) 1: 4.

Derivation of the name: Named after Hungary, the country of the type locality .

Holotype: MÁFI E. 9521 ( Fig. 12H), a megalospheric specimen split along the equatorial plane.

Type locality: Úrhida ( Hungary), sample Úrhida 2.

Type horizon: Middle late Bartonian, SBZ 18 B.

Material.—26 well−preserved megalospheric specimens.

Diagnosis.— Heterostegina reticulata populations with X mean ranging from 11 to 17.

The equatorial section of A−forms.—The secondary chamberlets are of rhomboid to hexagonal shape; their arrangement is close to regular. For numerical features see Table 5.

Remarks.—This name has been preliminarily used by Less and Gyalog (2004) for the population from sample Úrhida 2, however, with no description, so the taxon is introduced formally here.

Geographic and stratigraphic distribution.—Middle late Bartonian (SBZ 18 B) of Hungary (samples Úrhida 2, 3), and SW France (Siest).
