Gangugia simplex :-- Hoffman, 1976: 179, figs 11−13, elevated to species rank; Golovatch, Hoffman, Adis, Marques, Raizer, Silva, Ribeiro, Silva and Pinheiro, 2005: 277.

Additional material. BRAZIL: Goiás: Jataí (-10.471803°; -50.515290°), Fazenda Nova Orlândia , 2♂ and 1♀, I.1964, Exped. Dep. Zool. coll. ( VMNH 110614 ) .

Diagnosis. Adult males differ from all other species of the genus by the combination of the following characters: presence of indentations in the prefemoral process ( Fig. 13D ) and the prefemoral process not completely involving the solenomere, in ectal view ( Fig. 13E–F ).

Description. Male (Holotype, MZSP 1077). Coloration (long-preserved in 70% ethanol): Head and antennae ocher yellowish. Body ocher and with the border of the paranota and posterior margin of the metaterga slightly whitened ( Figs 13A–C ). Legs ochre yellowish. Gonopod aperture on seventh body ring broken. Telson ocher. Total length: 65.67. Total width: 9.43. Collum, length 2.55, width 8.75. Antennomere lengths (1>7): 0.74; 2.00; 1.78; 1.47; 1.36; 1.47; 0.30. Podomeres lengths (1>7): 1.08; 1.44; 2.61; 1.24; 1.50; 1.48; 0.55. Gonopod aperture, length 1.80, width 3.73. Telson, length 0.93. Gonopod: length 2.98, width 2.39. Gonocoxae: length 1.17, width 1.09. Telopodite: length 2.83, width 1.34. Prefemoral process long (smaller than the solenomere), narrow and curved, terminal portion presenting several indentations ( Fig. 13D ). Long, narrow and curved solenomere ( Figs 13E–F ). Cingulum in medial position ( Fig. 13F ). Apex of the solenomere sickle-shaped ( Fig. 13F ).
