Morphological and biogeographic data support the recognition of 19 species.  The following taxonomic scheme is proposed: L. angulatum (Emery) stat.nov. [= pordescens (Wheeler) syn.nov.], L. dispertitum (Forel), L. flavescens (Wheeler & Mann) stat.nov., L. fuscum Mayr, L. gallardoi (Brèthes) [=breviscapa (Santschi) syn.nov. = impotens (Santschi) syn.nov.], L. humile (Mayr) [=arrogans (Chopard) = riograndense (Borgmeier)], L. iniquum (Mayr) [= bicolor (Forel) syn.nov. = dominicense (Wheeler) syn.nov. = fuscescens (Wheeler) syn.nov. = melleum (Wheeler) syn.nov. = nigellum (Emery) syn.nov. = succineum (Forel) syn.nov.], L. keiteli (Forel) [= subfaciatum (Wheeler & Mann) syn.nov.], L. leucomelas (Emery) [= aspidocoptum (Kempf) syn.nov.], L. micans (Forel) stat.nov. [= platense (Forel) syn.nov. = scotti (Santschi) syn.nov.], L. oblongum (Santschi), L. piliferum (Mayr).  Seven species are described as new: L. anathema sp.nov., L. aztecoides sp.nov., L. cerradense sp.nov., L. cryptobioticum sp.nov., L. neotropicum sp.nov., L. pulex sp.nov., & L. tsachila sp.nov.  Seventeen species are sorted into one of 4 groups associated with the species L. fuscum, L. humile, L. iniquum, or L. neotropicum, & 2 species are left unassigned.  New generic diagnoses are provided for worker, male, & queen castes.  Shattuck's (1992a) generic descriptions of the worker, male, & queen castes are modified slightly to take into account expanded knowledge of character state variation.  Worker &, where known, male & queen castes are described.  Diagnoses, illustrations, & keys are supplied for worker & male castes.  Discussions of variation, comparisons to similar species, & nomenclatural issues are given for each species.  Also included are synopses of life history traits such as queen number, colony structure, geographic distribution, nest site, habitat records, & associations with parasitoid Pseudacteon flies (Diptera: Phoridae).  Iridomyrmex humilioides = Linepithema humilioides= Gracilidris humilioides is excluded from Linepithema.   Linepithema inacatum is incertae sedis in Linepithema.]1 aWild, A L  uhttps://antkey.myspecies.info/en/content/taxonomic-revision-ant-genus-ilinepithema-ihymenoptera-formicidae
