5) Opinion 

1)  lobopod : Snodgrass 1938

ORIGINAL SPELLING (Snodgrass 1938): lobopod branch (in English)

COMMENT. Snodgrass (1938) used only the English words "lobopod branch" in a phylogenetic tree (Snodgrass 1938: Fig. 54); here the word "lobopod" is used not as a taxon name, but as an epithet which means that limbs represent lobopodia (unlike the "chaetopod branch", where limbs represent chaetopodia); neither the text nor the tree make it clear whether this term is applied to the whole lineage including Onychophora and Euarthropoda or just to an ancestral group at its base.


2) Lobopoda Boudreaux 1979

NOMEN: Lobopoda Boudreaux 1979 [H.B. Boudreaux. Significance of intersegmental tendon system in arthropod phylogeny and monomonophyletic classification of Arthropoda. pp. 551-586. - In.: A.P. Gupta [ed.]. Arthropod Phylogeny. Van Nostrand Reinhold Company, N.Y., 1979, 1-762]

ORIGINAL LISTED MEMBERSHIP (Boudreaux 1979): Onychophora + Arthropoda

SENIOR CIRCUMSCRIPTIONAL SYNONYM:
= Gnathopoda Lankester 1877

JUNIOR CIRCUMSCRIPTIONAL SYNONYMS:
= Panarthropoda Nielsen 1995
= Podophora
Waggoner 1996
= Antennopoda De Haro 1998

NON-MONOSEMANTIC CIRCUMSCRIPTIONAL SYNONYMS (with indeterminate position of Onychophora):
= Endomyaria Spinola 1850, s.l.

TYPIFIED NAME IN BASIC FORMAT: Araneus/fg (incl. Peripatus) [fg:(1757)1758]
TYPIFIED NAMES IN USE: -

MODERN STATUS: junior synonym of Gnathopoda Lankester 1881; belongs to a generally accepted, holophyletic taxon (Kluge 2000).

COMMENT. The name Lobopoda was used with authorship "Snodgrass 1938" (Boudreaux 1979, Kluge 1999, 2000). This name was ascribed to Snodgrass 1938, who used the English words "lobopod" and "chaetopod" (see above), by analogy with the taxon name Chaetopoda.


3) Lobopodia Hou & Bergström 1995

NOMEN: Lobopodia Hou & Bergström 1995 [X. Hou, J. Bergstrom. Cambrian lobopodians - ancestors or extant onychophorans? - Zool. Journ. Linn. Soc., 1995, 114 (1): 3-19]

ORIGINAL LISTED MEMBERSHIP (Hou & Bergström 1995): Archonychophora + Protonychophora + Scleronychophora + Paronychophora + Onychophora

JUNIOR CIRCUMSCRIPTIONAL SYNONYM:

= Polylobopoda Waggoner 1996

NON-MONOSEMANTIC CIRCUMSCRIPTIONAL SYNONYMS (with uncertain position of extinct taxa):

= Polypoda Guilding 1826

= Malacopoda Blainville

= Onychophora Grube 1853

= Protracheata Haeckel 1866

= Prototracheata Schimkewitsch 1890

= Monognatha Lameere 1895

= Monognatha Monoprostomera Lankester 1904

= Protarthropoda Lankester 1904

= Tracheoidea Krausse & Wolff 1919

TYPIFIED NAME IN BASIC FORMAT: Peripatus/fg [f: Peripatiens Audouin & Milne-Edwards 1833; g: Peripatus Guilding 1826, typus P. juliformis Guilding 1826]
TYPIFIED NAMES IN USE: Peripati, Peripatida, Peripatidae, Peripatidea, Peripatii, Peripatoidea

MODERN STATUS: unclear; systematic position of extinct taxa originally attributed here is discussionable.

COMMENT. The name Lobopodia was used with authorship "Snodgrass 1938" (see above) (Hou & Bergström 1995, Poinar 2000).

NOMEN: Lobopoda Cavalier-Smith 1998 [T. Cavalier-Smith A revised six-kingdom system of life. - Biological Review of the Cambridge Phylosophgical Society 73 (3): 203-266]

SENIOR CIRCUMSCRIPTIONAL SYNONYMS:

5)  OPINION

The same epithet "lobopod" used by Snodgrass (1938) was subsequently interpret as Latin taxa names with different spelling (Lobopoda and Lobopodia) and qiute different circumscription - from a small taxon including only Onychophora, to a great taxon uniting Onychophora with Arthropoda. In order to avoid confusion, the both names Lobopoda and Lobopodia in all their senses should not be used. Lobopoda Boudreaux 1979 should be regarded as an invalid junior synonym of Gnathopoda Lankester 1881; Lobopodia Hou & Bergstrom 1995 should be regarded as an invalid (while older) synonym of Polylobopoda Waggoner 1996; Lobopoda Cavalier-Smith 1998 should be regarded as an invalid junior synonym of Pararthropoda Vandel 1949
