Diagnosis: Body predominantly black or bluish-black ( Fig. 13 ); head black ( Fig. 8 ); antenna with 23-27 flagellomeres, with light brown scape; mid and hind tibia bicolor whitish at the base and black near apex; anteri- or wing with vein 3rs-m present, absent, or incomplete, with areolet present or absent; first metasomal segment with lateromedial longitudinal carina strong extending about 0.60-0.70× of segment length ( Fig. 12 ); metasomal tergite II with narrow and inconspicuous laterotergites ( Fig. 14 ).

Description of male genitalia ( Fig. 31 ): Genital capsule length 0.63 mm and width 0.36 mm; basal ring, dorsally interrupted; paramere in dorsal view basally almost straight and not fused, concave at the middle of the inner margins; in ventral view, with straight pre-apical margin; pilosity concentrated in the region apical of the paramere bearing sparse and long setae; digitus wider than half of the cuspis width; apodeme of aedeagus shorter than aedeagus; tubular aedeagus with slightly dilated apical region, with two dilated lobes;aedeagus about ⅔ of the total length of the genital capsule;hypopygium with lateral margins converging distally;longer than wide;distal end emarginated, with dense setae centrally; smooth surface ( Fig. 34 ).

Distribution ( Fig. 36 ): Alagoas, Espírito Santo, Rio de Janeiro , São Paulo ( Araujo, 2011; Fernandes et al., 2010), Santa Catarina ( Gauld & Sithole, 2002). New records:

Bahia, Distrito Federal, Mato Grosso, Mato Grosso do Sul, Minas Gerais, Paraná, Piauí, and Rondônia states.The distributional pattern of Leurus caeruliventris is broadly expanded for Brazil and now includes the following Brazilian biomes: Amazon, Caatinga, Mata Atlântica, and Pantanal.

Comments: The specimens examined showed high variability in morphology, with subtle variations in the size of individuals,presence,or absence of areolet on the fore wings, and intensity of leg coloration of specimens, even within specimens collected at the same locality. The coloration of the legs ranged from whitish to yellowish.
