Bioacoustics of Leptonetela biocellata

Diagnosis. This species resembles Leptonetela quinquespinata (Chen & Zhu, 2008) in similar proportions of each part of the male palp; slightly wide, flattened conductor; similar shape of the atrium ( Figs 1 B–D, 2C, 3A, B, 4A, C in this present paper; figs 44B–D, 45C, 46A, B, 47B, D in Wang & Li 2011 ). The new species can be distinguished by eyes reduced to two white spots; median apophysis completely covered by the conductor, neither present in L . quinquespinata ( Figs 1A, B , 2A , 4C in this present paper; figs 44A, B, 45A, 47B, D in Wang & Li 2011 ); chelicerae with ten promarginal and seven small retromarginal teeth in new species ( Fig. 4D ), but nine promarginal and five small retromarginal teeth in L. quinquespinata (fig. 47C in Wang & Li 2011 ). Males of the new species resemble L. anshun Lin & Li, 2010 , L. grandispina Lin & Li, 2010 , L. liping Lin & Li, 2010 , L. maxillacostata Lin & Li, 2010 , L. tetracantha Lin & Li, 2010 , L. zhai Wang & Li, 2011 , L. yaoi Wang & Li, 2011 , L. thracia Gasparo, 2005 , L. mita Wang & Li, 2011 , and L. microdonta (Xu & Song, 1983) in pedipalpal tarsus with a transverse groove, slightly contracted mesially, with no distinct wrinkles (figs 4A, B, 19A, B, 31A, B, 33A, B, 49A, B in Lin & Li 2010 ; figs 70A, B, 67A, B, 59A, B, 30A, B, 34A, B in Wang & Li 2011 ). It can be distinguished from all the former species by the presence of two white eyespots ( Figs 1A , 2A ); membranous and slightly wide flattened conductor; embolus distally twisted at one third; median apophysis hidden by the conductor ( Figs 1B , 4C ). Females resemble L. parlonga Wang & Li, 2011 by the shape of atria and spermathecae; but can be distinguished by eyes reduced to two eyespots in the new species ( Figs 2A , 3C ), normal six eyes in L. parlonga (fig. 37A in Wang & Li 2011 ); anterior margin of the atrium decorated with dense short and slender hairs in L. parlonga (fig. 37C in Wang & Li 2011 ), absent in the new species ( Fig. 2C ).
