Leptogoniulus sorornus (Butler, 1876) ( Figs. 2B , 6 E-F)

Descriptive notes: See Shelley & Lehtinen (1999: 1383, figs. 1-7).

Note: An overview of its taxonomic status was made by Shelley & Lehtinen (1999).

Identification: According to the diagnosis made by Shelley & Lehtinen (1999), males of L. sorornus are recognized by coxae of the anterior gonopods widely separat- ed by apically broad and subtruncate sternum ( Fig. 6E ), and telopodites apically uncinated. Telopodites of the posterior gonopods with broad medial lobe, and apically rounded with notches along the distal margin ( Fig. 6F ).

Distribution: Leptogoniulus sorornus presents a tropical distribution ( Hoffman, 1999; Shelley & Lehtinen, 1999; Korsós, 2004). In Brazil, the species has been recorded in the old-named state of Guanabara (now known as Rio de Janeiro), São Mateus, and Salvador (approximately 1,500 km from Rio de Janeiro) ( Shelley & Lehtinen, 1999). All records were obtained from the literature.
