Diphyes latiusculum
Diphyes latiusculum Matsuoka, 1974
Holotype: Matsuoka, 1974, pl.44, fig.6
Locus typicus: Fujiwara-cho, Nara City, Nara Prefecture, Japan
Stratum typicum: Early-Middle Miocene
Original diagnosis: Matsuoka, 1974, p.329
Ovoid to elongate central body with thin, microgranular surface and microgranular surface of the large antapical process. Processes formed from outer wall and of two types. One single broad antapical process, and slender, bifid or oblate processes. Total number of processes exceeding fifty.
Description: Matsuoka, 1974, p.329:
The present specimens of Diphyes have a characteristic apical archeopyle and single large antapical process. The antapical process is hollow, cylindro-subconical and open distally. The tips of the antapical process are irregularly denticulate or fibroid. The slender processes are commonly single, sometimes connect with adjacent ones at the base. They are ordinarily bifid, sometimes oblate and closed distally, and the both types do not connect with interior of the central cavity. The parallel arrangement of these slender processes indicates the cingular and sulcal regions.
Dimensions: Holotype: central body length (without operculum) 60 Ám, central body breadth 72 Ám, prosess length 28 Ám.
Affinities:
Matsuoka, 1974, p.329: The present species differs from Diphyes colligerum in the shape of the central body and the distal partsof the slender processes.
