Holotype male from Centro de Pesquisas e Conservação da Natureza Pró-Mata (CPCN Pró-Mata), São Francisco de Paula, Rio Grande do Sul, Brazil , 02.I.2001 , R. Ott leg. (MCN 619). Paratype female, same data as holotype , 02.II.2002 (MCN 618). Etymology. The epithet refers to “serra”, the local name of a mountainous area of the state of Rio Grande do Sul, where São Francisco de Paula municipality is located. Diagnosis. Rhinocricus serranus is close to Rhinocricus mogyanus Schubart, 1944 , presenting coxites and telepodites in “V” shaped position, far from the sternite ( Fig. 23 ), differs from this species by presenting a longer distal portion of the sternite and by the solenomere, in the posterior gonopod, longer than the tibiotarsus ( Fig. 25 ). FIGURES 23–29. Rhinocricus serranus sp. nov. 23–24, anterior gonopod. 23, anterior view. 24, posterior view. 25, left posterior gonopod, anterior view. 26–27, male, lateral view. 26, posterior segments. 27, anterior segments. 28–29, female, lateral view. 28, posterior segments. 29, anterior segments. Scale bar = 1.0 mm (Figs. 23–25). Description. Male, holotype ( Figs. 26, 27 ). With 53 segments. Length 118. Width 8. Clypeus chestnut with spaced 2–2 supra-labial setae. Labrum yellowish-brown with 12–12 setae. Antennae brown, with numerous sensory cones (more than 20). Collum yellowish-brown with dark-brown posterior margin and rounded ventrolateral borders. Prozonites yellowish-brown; metazonites yellowish-brown (anterior ones) to olive (posterior ones) with dark-brown posterior margins. Epiproct yellowish-brown with rounded apex, surpassing the paraproct. Paraproct and hypoproct yellowish-brown. Legs yellowish-brown, with elongated coxae at third and fourth pairs of legs.

Scobinae beginning at sixth segment. Anterior gonopod ( Figs. 23, 24 ). Triangular sternite with rounded distal portion, longer than coxite and telepodite. Coxite with triangular internal lobe and large base; telepodite as long as coxite and rounded distally. Posterior gonopod ( Fig. 25 ).
