FIGURES 68–73 , 86

Storthotropis giganteus Schubart, 1949: 22 , figs 3, 4.

Male holotype, from Espírito Santo, Brazil, ii.1911, E. Garbe coll., deposited in MZSP 100 , examined.

Odontopeltis giganteus : – Hoffman, 1981a: 60, figs 8, 12.

Additional material examined: BRAZIL: 1♂ (without label information) ( MZSP 908 ); Espírito Santo: Santa Teresa , (19°56′09′′S, 40°36′00′′W), 1♂ and 1♀, 19.i. 1964 ( MZSP 564 ); Linhares , (19°23′27′′S, 40°04′19′′W), 2♂, 1981, B. Kuth coll. ( MNRJ 11950 ) .

Diagnosis: Males of Odontopeltis giganteus differ from all other species of the genus by the curved tip of process B ( Fig. 68 ). Process B large, not obscured by solenomere in ventral view ( Fig. 69 ). Coxae without spiniform process ( Fig. 68 ). Femoral region as wide as prefemoral region, unlike in all other species of Odontopeltis .

Redescription: Male (Holotype, MZSP 100): Head red. Body reddish. Paranotal tips and telson yellow. Legs reddish. Paranotal teeth formula: 0-0-0-0-2-1-2-2-3-3- 3-2-3-3-2-2-2-1-0-0. Total length 107. Collum 5.1 long, 15.6 wide. Antennae missing. Genital opening 2.5 long, 4.08 wide. Telson 1.4. Gonopods: macrobristles in an inclined line, close together, distance between them less than half length of a bristle. Prefemoral region 2.5 × longer than femoral region. Process A triangular and long, almost the size of the solenomere, without projections. Solenomere with a median process (arrow, visible in ventral view, Fig. 69 ) and with a hump (arrow, visible in mesal view, Fig. 68 ).

Female: Body as in male. Paranotal teeth formula: 0-0-0-0-2-2-3-2-3-2-2-3-3-2-2-2-1-1-1. Total length 89. Collum 5.0 long, 14 wide. Telson 2.0. Cyphopod short and oval-shaped, covered by bristles. Ectal valve slightly bigger than mesal valve ( Figs 53 , 71 ). Mesal valve subrectangular (mesal view, Fig. 73 ). Ectal valve lozenge-shaped ( Fig. 72 ).
