Some morphological characters of the studied specimens, such as the dorso-laterally compressed carapace, the cylindrical shape of the carapace, and the strong chelate P1 allow us to assign them tentatively to the infraorder +Astacidea +, including all the marine chelate lobsters. Indeed the assignment to this infraorder is tentative because, according to + +Karasawa +et al. +(2013: 110) + +, some other diagnostic characters, such as the rostrum with supra- and subrostral teeth, s2 larger than s3-s6, and the uropodal exopod with diaeresis do not fit with the characters of the studied specimens. + + +According to + +Karasawa +et al. +(2013: 94) + +the new classification for lobsters, after the phylogenetic systematics proposed by +Scholtz & Richter (1995) +and + +Wahle +et al. +(2012) + +, includes two sections for the infraorder +Astacidea Latreille, 1802 +, as follows: Homarida +Scholtz & Richter, 1995 +and Astacida +Scholtz & Richter, 1995 +. The former includes three superfamilies, Enoplometopoidea de Saint Laurent, 1988 ( +Enoplometopidae de Saint Laurent, 1988 +; +Uncinidae Beurlen, 1930 +); Stenochiroidea Beurlen, 1928 ( +Stenochiridae Beurlen, 1928 +); and Nephropoidea Dana, 1852 ( +Nephropidae Dana, 1852 +). The latter includes three superfamilies, Protastacoidea Albrecht, 1983 ( +Protastacidae Albrecht, 1983 +); Astacoidea Latreille, 1802 ( +Astacidae, Latreille, 1802 +; +Cambaridae Hobbs, 1942 +; +Cricoidoscelosidae Taylor, Schram & Yan-Bin, 1999 +); and Parastacoidea Huxley, 1879 ( +Parastacidae Huxley, 1879 +), truly “ … +poorly known in the fossil record. +” ( + +Karasawa +et al. +, 2013 + +). + + +Though the two sections have substantial morphological differences concerning the rostrum (short or elongate with supra- or subrostral teeth), the carina and groove system of the carapace, the pleon (pleurae more or less pointed or rounded), and the telson (with or without diaeresis), they share one constant and consistent diagnostic character, the uropodal exopod with diaeresis, according to the most recent phylogenetic systematics proposed by + +Karasawa +et al. +(2013) + +. + + +Based upon the diagnoses proposed by + +Karasawa +et al. +(2013) + +for each family within the two sections, we point out that some morphological characters of the studied specimens, such as the strongly tuberculate carapace and P1; a short rostrum with serrate suprarostral margins, bearing 3-4 pairs of teeth; a deep cervical groove and a weak antennal groove not forming the characteristic “W” shape; s2 with subrounded pleura partially overlapping those of s1 and s3; smooth s1, s3- s6 with rounded pleurae; a subtrapezoidal telson without diaeresis and lateral margins with one median movable spine and two distal movable spines; chelate P1 slightly heterochelous (peculiar shape of the P1 chela: P1 index occlusal margin with a row of strong rounded teeth inclined forward and arranged randomly; P1 dactylus occlusal margin with a row of pointed, elongate, and slender teeth strongly inclined distally); and mainly the uropodal exopod without diaeresis, are so unique and peculiar that the studied specimens do not fit any diagnosis for known clawed lobster families, provided by the authors. + + +Therefore, these differences warrant a distinct family within the +Astacidea +to accommodate the +type +genus + +Amazighopsis + +n. gen. + + +The new family cannot be assigned to both sections of the infraorder +Astacidea +based upon the characters proposed by + +Karasawa +et al. +(2013: 110 + +, 113). According to +Holthuis (1991: 31-47 +; fig. 61), the new family may be, however, tentatively assigned to the section Homarida based upon + +Nephropsis +Wood-Mason, 1873 + +, the sole genus within this section, including the extant species with or without a diaeresis on the uropodal exopod. Moreover, the lack of the diaeresis on the telson in the new family, a peculiar character of the Homarida, as proposed by + +Karasawa +et al. +(2013: 116) + +(vs. telson with diaeresis in Astacida), would further support the assignment of the new family to this section. + + + + \ No newline at end of file diff --git a/data/1F/27/56/1F275648FFDEFFF6FC263C9C658CFEAA.xml b/data/1F/27/56/1F275648FFDEFFF6FC263C9C658CFEAA.xml new file mode 100644 index 00000000000..9b3e68d90ab --- /dev/null +++ b/data/1F/27/56/1F275648FFDEFFF6FC263C9C658CFEAA.xml @@ -0,0 +1,152 @@ + + + +Amazighopsidae, a new family of decapod macruran astacideans from the late Cretaceous (Cenomanian-Turonian) of Gara Sbaa, Southeastern Morocco + + + +Author + +Garassino, Alessandro +Sezione di Paleontologia degli Invertebrati, Museo di Storia Naturale, Corso Venezia 55, 20121 Milano, Italia. +alessandro.garassino@comune.milano.it + + + +Author + +Pasini, Giovanni +Via Alessandro Volta 16, 22070 Appiano Gentile (Como), Italia.
