Stenodactylina pseudoventrosa Devillez & Charbonnier 2021, n. comb.
No full textStenodactylina pseudoventrosa (Beurlen, 1928) n. comb. (Fig. 17A, B) Eryma pseudoventrosa Beurlen, 1928: 158; 1933: 90. — Schweitzer et al. 2010: 24. Eryma modestiformis (pars.) – Förster 1966: 118. TYPE MATERIAL. — Holotype GPIT Ar/294/3. TYPE LOCALITY. — Hülben, Baden-Würrtemberg, Germany. TYPE AGE. — Kimmeridgian. DESCRIPTION Carapace Sub-cylindrical carapace; spiny rostrum; fusiform intercalated plate; narrow post-orbital area; deep and wide cervical groove, strongly inclined dorsally, inflected at carapace mid-height, joined to dorsal margin and to antennal groove; deep and wide antennal groove; short, wide gastro-orbital groove, deep and oblique, originating as a median inflexion of cervical groove; postcervical and branchiocardiac grooves subparallel, slightly curved, very close; deep postcervical groove, not joined to dorsal margin and interrupted in hepatic region; deep branchiocardiac groove, strongly inclined, not joined to dorsal margin. Ornamentation Carapace covered by small tubercles preceded by crescentshaped depressions; cephalic region with an oblique orbital row of tubercles. DISCUSSION Known by a single cast of carapace, this species was originally assigned to Eryma (Beurlen 1928), and then regarded as a synonym of Eryma modestiforme (see Förster 1966). Careful examination of the holotype clearly shows the absence of junction between postcervical and branchiocardiac grooves and the interruption of the postcervical in the hepatic region. This groove pattern is diagnostic of Stenodactylina. So, the new combination Stenodactylina pseudoventrosa, n. comb. is here proposed. The strong proximity of the postcervical and branchiocardiac grooves allows the distinction of S. pseudoventrosa, n. comb. from S. burgundiaca and S. delphinensis. Moreover, the ventral extremity of the postcervical groove of S. pseudoventrosa, n. comb. is lower than in S. burgundiaca, S. guisei, S. shotoverigiganti n. sp., S. triglypta, and S. walkerae. Contrary to S. australis, S. burgundiaca, S. delphinensis, S. deslongchampsi, S. granulifera, S. guisei, and S. triglypta, an orbital row is present in S. pseudoventrosa. There are also depressions and no coarse elements in its ornamentation contrary to S. australis, S. deslongchampsi, S. lagardettei, S. shotoverigiganti n. sp., S. triglypta, and S. walkerae.Published as part of Devillez, Julien & Charbonnier, Sylvain, 2021, Review of the Late Jurassic erymoid lobsters (Crustacea: Decapoda), pp. 25-73 in Geodiversitas 43 (2) on page 61, DOI: 10.5252/geodiversitas2021v43a2, http://zenodo.org/record/448647

Careful examination of the specimen shows the absence of junction between postcervical and branchiocardiac grooves, and the interruption of the postcervical groove in hepatic region while the branchiocardiac groove is joined to the hepatic groove. This groove pattern is diagnostic of <i>Stenodactylina</i>. Moreover, some morphological features allow the distinction of this specimen from all other representatives of the genus for which the carapace is known. Indeed, the postcervical groove is shorter than that of <i>S. australis</i>, <i>S. delphinensis</i> (Moret, 1946), <i>S. deslongchampsi</i> (Van Straelen, 1925), <i>S. granulifera</i>, <i>S. lagardettei</i>, <i>S. pseudoventrosa</i>, and <i>S. walkerae</i> (Feldmann & Haggart, 2007). It is also slightly curved contrary to <i>S. burgundiaca</i> (Crônier & Courville, 2004), <i>S. delphinensis</i>, <i>S. granulif-era</i>, <i>S. triglypta</i>, and <i>S. walkerae</i>. Only the ω area is inflated while it is flat in some species (<i>S. australis</i>, <i>S. delphinensis</i>, <i>S. deslongchampsi</i>) or both ω and χ areas are inflated in some others (<i>S. burgundiaca</i>, <i>S. granulifera</i>, <i>S. guisei</i> (Wright, 1881), <i>S. lagardettei</i>). The ornamentation of the specimen is thin and only made of tubercles contrary to <i>S. australis</i>, <i>S. burgundiaca</i>, <i>S. delphinensis</i>, <i>S. granulifera</i>, <i>S. guisei</i>, <i>S. lagardettei</i>, and <i>S. pseudoventrosa</i>. Finally, there is an orbital row, which is absent in <i>S. australis</i>, <i>S. burgundiaca</i>, <i>S. delphinensis</i>, <i>S. deslongchampsi</i>, <i>S. guisei</i>, and <i>S. triglypta</i>. Considering all these elements, we consider this specimen as a representative of a new species of erymid lobsters: <i>Stenodactylina shotoverigiganti</i> n. sp.</p>Published as part of <i>Devillez, Julien & Charbonnier, Sylvain, 2021, Review of the Late Jurassic erymoid lobsters (Crustacea: Decapoda), pp. 25-73 in Geodiversitas 43 (2)</i> on page 60, DOI: 10.5252/geodiversitas2021v43a2, <a href="http://zenodo.org/record/4486479">http://zenodo.org/record/4486479</a>
Stenodactylina strambergensis
No full textStenodactylina strambergensis (Bachmayer, 1959) (Fig. 17 G-I) Erymastacus strambergensis Bachmayer, 1959: 940, pl. 2, fig. 2. Phlyctisoma strambergensis – Förster 1966: 144, pl. 18, fig. 8. Eryma strambergensis – Schweitzer et al. 2010: 24. Stenodactylina strambergensis – Devillez et al. 2016: 524. TYPE MATERIAL. — Holotype NMW 344/1959. TYPE LOCALITY. — Stramberg, Moravian-Silesian, Czech Republic. TYPE AGE. — Tithonian. DESCRIPTION Thoracic appendages Chelate P1; P1 propodus sub-rectangular, slightly globose dorso-ventrally; inner margin strongly compressed; rounded outer margin with a slight deviation at the basis of the index; slender index; wide and inflated dactylar bulge. Ornamentation P1 propodus covered by rounded, coarse and widely spaced tubercles; inner margin with a row of spines. DISCUSSION This species is known by some P1 propodi. Initially included within Erymastacus, then moved into Phlyctisoma (see Förster 1966) and Eryma (see Schweitzer et al. 2010), and finally to Stenodactylina by Devillez et al. (2016). This assignment is supported by the stronger compression of the inner margin than that of outer margin, the presence of a row of coarse tubercles on inner margin (present in most of the species of the genus), the strongly inflated dactylar bulge, and the fine basis of the index. Because only the P1 propodus of this species is known, the comparisons with other species of Stenodactylina are limited. Stenodactylina strambergensis has the particularity to have a relatively short propodus. Moreover, the ornamentation of S. strambergensis is homogeneous – only made of coarse tubercles – contrary to other species, except S. armata and S. triglypta.Published as part of Devillez, Julien & Charbonnier, Sylvain, 2021, Review of the Late Jurassic erymoid lobsters (Crustacea: Decapoda), pp. 25-73 in Geodiversitas 43 (2) on page 62, DOI: 10.5252/geodiversitas2021v43a2, http://zenodo.org/record/448647

Enoploclytia Enoploclytia – Mertin 1941: 160. — Glaessner 1969: 455. TYPE SPECIES. — Astacus leachii Mantell, 1822, by original designation. DIAGNOSIS BY Devillez et al. (2018). — Fusiform intercalated plate; wide, deep cervical groove, joined to dorsal margin and to antennal groove; long, wide gastro-orbital groove originating as a median inflexion of cervical groove, delimiting two gastroorbital lobes; sinuous postcervical groove, joined to dorsal margin and to hepatic groove, with ventral extension at carapace mid-height; short branchio-cardiac groove, interrupted in upper part of carapace, joined to dorsal margin, not joined to postcervical groove; concavo-convex hepatic groove, joined to cervical groove; prominent ω and χ bulges; inferior groove convex posteriorly, joined to hepatic groove; carapace with heterogeneous coarse ornamentation; massive globose P1 propodus, rounded in transversal section; long and thin P1 fingers (straight in dorsal view); occlusal margins armed with sharp and slender tooth; P1 merus with strong, prominent distal process at extern side of its ventral extremity. DISCUSSION Recently, Devillez et al. (2018) reported a specimen identified as Enoploclytia sp. from the Oxfordian of France (Fig. 18). Despite its poor preservation, this fossil exhibits the typical carapace groove pattern of the genus: elongated gastro-orbital groove, with two divergent distal branches, a sinuous postcervical groove joined to the posterior extremity of the hepatic groove and not joined to the branchiocardiac groove, which is short and interrupted in the branchial region (Fig. 18C). This specimen is the oldest occurrence of Enoploclytia, and the only known in the Jurassic. Indeed, Enoploclytia is more typical of the Cretaceous.Published as part of Devillez, Julien & Charbonnier, Sylvain, 2021, Review of the Late Jurassic erymoid lobsters (Crustacea: Decapoda), pp. 25-73 in Geodiversitas 43 (2) on page 64, DOI: 10.5252/geodiversitas2021v43a2, http://zenodo.org/record/448647
