Hybosa indecens Boheman, 1855: 3 (original description), syn. nov. Type localities. Chelymorpha ignobilis : ‘Brasilia’; Hybosa indecens : ‘Brasilia’. Type material examined. Hybosa indecens : HOLOTYPE : ♀ , pinned: ‘ Brasil . [w, p, s] || Bhn. [w, p, s] || Type. [w, p, s] || NHRS-JLKB | 000022206 [w, p, cb]’ ( NHRS ). Remarks. BOHEMAN (1854) described Chelymorpha ignobilis from ZMHB material. SPAETH (1909a) proposed for this species the genus Exestastica Spaeth, 1909 , however, pointed that the specimen he used for description did not fully agree with the original description of C. ignobilis but with additional specimens identified as that species in various collections. BOROWIEC (1999a) synonymized Hybosa margineguttata Wagener, 1877 with E. ignobilis but he was not able to locate the type of the latter in the ZMHB collection. During my stay in ZMHB I was also unable to trace the type of E. ignobilis and I thus follow Spaethʼs concept of the species. I studied the holotype of Hybosa indecens and found that it is conspecific with E. ignobilis and I therefore synonymize both species. Distribution. Brazil : Espirito Santo ( SPAETH 1909 ) and Rio de Janeiro ( BOROWIEC 1996 ).
