Description of two new species of Lycinus ( Araneae : Nemesiidae )

Two new species of Lycinus Thorell, 1894 are described in this paper, L. portoseguro sp. nov. and L. choros sp. nov. Lycinus portoseguro sp. nov. is based on male and female from Porto Seguro, state of Bahia, Northeastern Brazil. This is the first record of a species of Lycinus from Brazil. Males of L. portoseguro sp. nov. differ from the remaining species of the genus by the presence of a retrolateral megaspine on tibia I and by the short embolus. Females can be distinguished by the scopulae divided on tarsi II. Lycinus choros sp. nov. is based on one male from La Serena, IV Region (Coquimbo), Chile. It is the eighth species described from this country. L. choros sp. nov. resembles L. epipiptus (Zapfe, 1963) by the longer embolus and differs from it by the short palpal tibia and by the scopulae undivided on male tarsi I-II.


MATERIAL AND METHODS
The examined material is deposited in the following institutions (abbreviation and curator in parentheses): Instituto Butantan, São Paulo (IBSP, I. Knysak), Museu de Zoologia da Universidade Federal da Bahia, Salvador (MZUFBA, T.K. Brazil) and Museo Argentino de Ciencias Naturales "Bernardino Rivadavia", Buenos Aires (MACN, C. Scioscia).Spine notation follows PETRUNKEVITCH (1925).All measurements are in millimeters and were taken with a millimetric ocular lens.The length of leg segments was measured between joints in dorsal view.Length and width of carapace, eye tubercle, labium and sternum are maximum values obtained.Total body length includes chelicerae but not the pedicel and spinnerets.All drawings were made with the aid of a camera lucida attached to a Leica MZ 12.5 stereomicroscope.Spermathecae were cleared with clove oil and illustrated in dorsal view.Abbreviations: (AME) anterior median eyes, (ALE) anterior lateral eyes, (PME) posterior median eyes, (PLE) posterior lateral eyes, (PLS) posterior lateral spinnerets, (d) dorsal, (v) ventral, (p) prolateral, (r) retrolateral, (ap) apical, (s) superior.
Diagnosis.Males of L. portoseguro sp.nov.differ from those of the remaining species of the genus by the presence of a retrolateral megaspine on tibia I (Figs 9 and 10) and by the short embolus (Figs 1-3).Females can be distinguished by the scopulae divided on tarsi II (Fig. 11).
Distribution.Known only from the type locality.
Etymology.The species name is a noun in apposition, taken from the type locality.
Lycinus choros sp.nov.Diagnosis.L. choros sp.nov.resembles L. epipiptus (Zapfe, 1963) by the longer embolus and differs from it by the short palpal tibia (Fig. 17) and by the scopulae undivided on male tarsi I-II.
Female.Unknown.Distribution.Known only from the type locality.
