“…Stenocheles esocinus is based on a single fragmentary specimen consisting of a major chela and an abdomen (no carapace is preserved) from the Lower Coniacian of the Rohatce Member of the Teplice Formation. Their morphology is very close to Oncopareia bredai Bosquet, 1854, the type species of Oncopareia ; thus, we agree with the synonymisation of Stenocheles with Oncopareia (as already suggested by Tshudy 1993, Tshudy & Sorhannus 2000, Schweitzer et al 2010).…”

Because of close morphological affinities, fossil cheliped fragments of the ghost shrimp Ctenocheles (Decapoda, Axiidea, Ctenochelidae) can be easily misidentified as remains of different decapod crustacean taxa. Re-examination of the Cretaceous decapods deposited in the National Museum in Prague revealed that all supposed specimens of the lobster genus Oncopareia found in the Middle Coniacian calcareous claystones of the Březno Formation, including one of the Fritsch's original specimens of Stenocheles parvulus, actually belong to Ctenocheles. This material together with newly collected specimens from the same locality, allowed for erection of a new species, Ctenocheles fritschi. Its major chela possesses a serrated ischium and ovoid, unarmed merus; therefore, it is considered a close relative of the extant C. collini and C. maorianus. Ctenocheles fritschi sp. nov. represents the first report on the occurrence of the genus from the Bohemian Cretaceous Basin. It is one of the oldest records of Ctenocheles and simultaneously one of the best preserved fossils of the genus reported to date. Confusing taxonomy of S. parvulus is reviewed and shortly discussed.•

“…Tshudy (1993, p. 71–72) redefined Hoploparia as follows: “Rostrum long, spinose. Postcervical groove well impressed over most of length; becomes subtler as it extends anteriorly toward cervical groove.…”

“…We use a total evidence approach in drawing generic boundaries—and, even then, with difficulty. Not surprisingly, in cladistic analyses, Homarus and Hoploparia plot out as sister groups (Tshudy, 1993; Tshudy and Babcock, 1997; Ahyong, 2006; Karasawa et al, 2013).…”

“…The separateness of, and differences between, Homarus and Hoploparia have been long debated and are still not resolved. Many authors have considered Homarus and Hoploparia to be distinct (Mertin, 1941; Glaessner, 1969; Feldmann, 1974; Aguirre-Urreta et al, 1991; Tshudy, 1993; Feldmann and Crame, 1998; Tshudy and Sorhannus, 2003; Ilyin, 2005; Feldmann et al, 2007; De Grave et al, 2009; Schweitzer et al, 2010; Karasawa et al, 2013; and others). Woods (1931), Van Straelen (1936), and Stenzel (1945) viewed the two genera as synonymous.…”

The fossil record of the clawed lobster genus,Homarus, is appraised. The taxonomic history ofHomarusandHoplopariais summarized, and a list of species recognized for each is provided. A tabulation of all fossil species of the family Nephropidae permits assessment of nephropid species diversity through time. A new species ofHomarus,H.hungaricus, is recorded from the upper Oligocene (Chattian) Mány Formation at Mány, northern Hungary. The species is known by a single specimen consisting of a partial cephalothorax, a pleon minus telson, and partial chelipeds.Homarusis now known by two extant species (H.americanusandH.gammarus) and six fossil taxa, one of Early Cretaceous (Albian;H.benedeni) and five of Cenozoic age (H.hungaricusn. sp.,H.klebsi,H.lehmanni,H.morrisi, andH.percyi). The new fossilHomarusdiffers from modern congeners in aspects of carapace and pleon ornamentation and, especially, cutter claw shape. This is the fourth Oligocene occurrence of a nephropid species; all areHomarusand all are from Western Europe.Homarusmakes its appearance in the fossil record in the Early Cretaceous (Albian) and then is not known again until the Paleogene, despite the fact that nephropid lobsters in general are well known from the Late Cretaceous. Nephropid lobsters are better known from the Cretaceous than from the Cenozoic. Both raw species numbers and numbers corrected (normalized) for epicontinental sea coverage show that shelf-dwelling nephropid lobsters were most diverse during the Late Cretaceous.
