Family Microsolenidae Koby, 1889 Genus Eocomoseris Melnikova, Roniewicz, and Loeser, 1993

Type species: Eocomoseris gurumdyensis nom. nov. (= Eocomoseris ramosa Melnikova, 1993 ), Hettangian–Sinemurian, SE Pamirs, Tajikistan.

Remarks.—The genus Eocomoseris was first identified in the Jurassic and Cretaceous ( Melnikova et al. 1993); its species, among others, were earlier classified with the spongiomorphids. Ezzoubair and Gautret (1993) showed that there were essential microstructural differences between the Triassic Spongiomorpha (Hexastylopsis) ramosa Frech, 1890 and the remaining spongiomorphids, and stated that the former had a skeleton of scleratinian type.

The coral species included to the genus were discussed in Melnikova et al. 1993, and beside the species described in that paper (Early Jurassic E. lamellata Melnikova, 1993 , E. ramosa Melnikova, 1993 ) renamed herein (see below) into E. gurumdyensis nom. nov., both from the Pamirs, and Cenomanian E. raueni Loeser, 1993 from Germany), the list of coral taxa from the literature, which could be identified with Eocomoseris , is as follows: Early Jurassic Microsolena fromenteli Terquem and Piette, 1868 from France, and Actinaraea bevoayensis ( Alloiteau, 1958) in Turnšek et al. 1975 from Spain, and Kimmeridgian/Tithonian Thamnasteria vereschagini Krasnov, 1983 from Sakhalin. In addition, the following taxa having been classified in the Spongiomorphidae : the Early Jurassic Spongiomorpha crassa LeMaitre, 1935 ( LeMaitre 1935: 29, pl. 1: 4, not figs. 1–3) and S. (Heptastylopsis) asiatica LeMaitre, 1935 ( LeMaitre 1935: 33, pl. 3: 1, 3, 4), both from Morocco, and the Late Jurassic taxon from Spain attributed to Spongio−

morpha globosa Yabe and Sugiyama, 1931 by Flügel and Hötzl (1966: pl. 18: 1–5).

The genus ranges from the Late Triassic to early Late Cretaceous.
