species was Homarus-like in lacking a ventral extension of branchiocardiac groove.
18. H. dentata (Roemer, 1841) 19. H. dentonensis Rathbun, 1935 20. H. edwardsi (Robineau-Desvoidy, 1849) 21. H. fraasi (Böhm, 1891) 22. H. gabbi Pilsbry, 1901 23. H. gazdzicki Feldmann and Crame, 1998 – Miocene 24. H. gammaroides McCoy, 1849 – Eocene 25. H. georgeana Rathbun, 1935 26. H. gladiator Pilsbry, 1901 27. H. groenlandica Ravn, 1903 – Eocene 28. H. hakelensis (Fraas, 1878). Schweitzer et al. (2010) listed this as Homarus but one of us (DT) had supported Chong and Forster’s (1976) reference to Hoploparia; they noted its strong antennal ridge and unequal claws (Tshudy, 1993, p. 127).
29. H. hemprichi (Mertin, 1941) 30. H. horrida Schweitzer and Feldmann, in Schweitzer et al. (2003)
31. H. intermedia Secrétan, 1964 (According to Charbonnier et al., 2012, a junior synonym of H. collignoni. Tshudy, 1993, p. 130, tentatively regarded the species as separate from H. collignoni).
32. H. johnsoni Rathbun, 1935 – Eocene 33. H. kamimurai Kato and Karasawa, 2006 34. H. kamuy Karasawa and Hayakawa, 2000 35. H. longimana (Sowerby, 1826) 36. H. mcnairyensis Rathbun, 1929 37. H. mesembria Etheridge, Jr., 1917 38. H. mickelsoni Bishop, 1985. Schweitzer et al. (2010) listed this as Homarus, but one of us (DT) had referred it to Hoploparia (Tshudy, 1993, p. 146) as based on cepha- lothorax ornamentation, including long subdorsal and supraorbital carinae. It does, however, lack a ventral exten- sion of the branchiocardiac groove (as emphasized by Feldmann et al., 2007) and does possess a urogastric groove; both Homarus-like features.
39. H. minima de Tribolet, 1876 40. H. miyamotoi Karasawa, 1998 41. H. muncki Pelseneer, 1886 42. H. natsumiae Karasawa, Ohara and Kato, 2008 43. H. pelseneeri (Van Straelen, 1936) 44. H. pusilla Secrétan, 1964 45. H. riddlensis Feldmann, 1974 46. H. schlueteri Tribolet, 1874 47. H. sculpta Secrétan, 1964 (According to Charbonnier et al., 2012, a junior synonym of H. collignoni. Tshudy, 1993, p. 150 regarded the species as distinguishable from H. collignoni based on its “distinctly different” abdomen.)
48. H. senonensis Forir, 1887 49. H. shastensis (Rathbun, 1929) 50. H. stokesi (Weller, 1903) 51. H. tennesseensis Rathbun, in Wade, 1926 52. H. travisensis (Stenzel, 1945). Schweitzer et al. (2010) listed this as Homarus, but one of us (DT) had referred the species, known only by an incomplete palm, to Hoploparia (Tshudy, 1993, p. 183).
53. H. triboleti Borissjak, 1904 54. H. trigeri Van Straelen, 1936
55. H. tshudyi Schweitzer and Feldmann, 2001 56. H. uzbekensis Feldmann et al., 2007 57. H. wardi Quayle, 1987 – Eocene
Removed, as synonyms, from the list of Schweitzer et al. (2010)
1. H. belli M’Coy, 1849 (syn. H. gammaroides) (see Tshudy, 1993, p. 122)
2. H. saxbyi M’Coy, 1854 (syn. H. longimana) (see Tshudy, 1993, p. 131)
3. H. victoriae Quayle, 1987 (syn. H. gammaroides) (see Tshudy, 1993, p. 122)
Referred to Hoploparia by Schweitzer et al. (2010), but here transferred to a genus other than Hoploparia or Homarus
1. Hoploparia nephropiformis Schlüter, 1874 to Paraclytia Fritsch, 1887 (see Tshudy, 1993, p. 314).
2. Hoploparia scabra Bell, 1863 to Palaeastacus Bell, 1850 (see Tshudy, 1993, p. 371).
Genus uncertain
1. Homarus neptunianus Polkowsky, 2005 – known only by a single fixed finger (pollex), which could even belong to a crab claw (see also Polkowsky, 2014).
2. Hoploparia calcarifera Schlüter, 1879 – holotype, and sole specimen known, is lost; identification at generic and specific levels is uncertain without examination of the original mate- rial (Tshudy, 1993, p. 106).
3. Hoploparia eocaenica Lőrenthey, in Lőrenthey and Beurlen, 1929 – identity of the three specimens is unknown, but none is suggestive of Hoploparia (Tshudy, 1993, p. 363). Referred to Hoploparia by Schweitzer et al. (2010).
4. Hoploparia falcifer Fritsch, in Fritsch and Kafka, 1887 – known only by claws; generic identity unknown (Tshudy, 1993, p. 115). Referred to Hoploparia by Schweitzer et al. (2010).
5. Hoploparia heterodon – as used in Schweitzer et al. (2010). Oncopareia? heterodon Bosquet, 1854 is known only by claw fingers which are now assumed to have belonged to a crab (Tshudy, 1993, p. 371; Jagt et al., 2014).
6. Hoploparia? suecica Schlüter, 1874 – we have been unable to locate the repository; an identification is impossible on the basis of the illustration in Schlüter (1874) alone (Tshudy, 1993, p. 180). Referred to Hoploparia by Schweitzer et al. (2010).
7. Hoploparia? sulcicauda Schlüter, 1874 – material is lost; the generic identity remains unknown (Tshudy, 1993, p. 181). Referred to Hoploparia by Schweitzer et al. (2010).
8. Hoploparia tarrantensis Rathbun, 1935 – we have examined the holotype; it probably is not a nephropid (Tshudy, 1993, p. 364).
