Redefinition of the genus Bannapone and description of B. cryptica sp. nov. (Hymenoptera: Formicidae: Amblyoponinae) Author Eguchi, Katsuyuki Author Viet, Bui Tuan Author Yamane, Seiki Author Terayama, Mamoru text Zootaxa 2015 4013 1 77 86 journal article 10.11646/zootaxa.4013.1.5 9ec6261c-14a0-43f5-9ed2-c941ebae38d8 1175-5326 241514 A3C24842-752D-4472-B372-04C718AE22F9 Bannapone zwaluwenburgi ( Williams, 1946 ) , comb. nov. Stigmatomma ( Fulakora ) zwaluwenburgi Williams, 1946 : 639 . Combination in Amblyopone : Brown, 1960a : 169 ; in Stigmatomma : Yoshimura & Fisher, 2012 : 19 . Redescription of the holotype and paratype : Onoyama, 1999 , 158. Holotype : worker, USA : Hawaii: Honolulu, ii/1941 , R. H. Van Zwaluwenburg leg., not examined (but images examined: CASENT0249113 at AntWeb). Paratypes : 3 workers , same data as the holotype , not examined; 1 worker , USA : Hawaii: Honolulu, 26/x/1945 , F. X. Williams leg., not examined. Remarks. The worker of B. zwaluwenburgi is easily distinguished from that of B. cryptica by: (1) frontal carinae inconspicuous, extending by no more than the length of frontal lobe; (2) antennal segments VIII–X each shorter than long; (3) posterolateral part of propodeum feebly produced posteriad. Williams (1946) described and placed this species under the subgenus Fulakora of the genus Stigmatomma . “ Fulakora ” was established by Mann (1919) for Stigmatomma celata Mann , 1919 (the type species), S. armigerum (Mayr, 1887) , S. saundersi (Forel, 1892) and S. minutum Forel, 1913 , and later synonymized with Stigmatomma by Brown 1949 and then with Amblyopone by Brown (1960) . According to the original description of S. celata , and type images of S. armigerum (CASENT0915647 at AntWeb), S. minutum (CASENT0102516 and CASENT0104570 at AntWeb) and S. saundersi (CASENT0102518 at AntWeb), the inner margin of mandible has triangular teeth arranged in two rows, or at least a part of the inner margin of mandible has more or less bifid teeth in the worker of these species. Thus, these species do not belong to Bannapone . An examination of the holotype and nontype images of B. zwaluwenburgi (CASENT0249113, CASENT0173925 and CASENT0187702 at AntWeb) has revealed that the mesosoma of CASENT0173925 in dorsal view is distinctly wider and shorter than that of the other specimens. To determine whether CASENT0173925 is an independent species or an ergatoid of B. zwaluwenburgi , colony series are needed.
