On the huntsman spider genera Sparianthina Banks, 1929 and Anaptomecus Simon, 1903 from South and Central America (Araneae, Sparassidae) Author Jaeger, Peter Senckenberg Research Institute, Frankfurt am Main, Germany Author Rheims, Cristina Instituto Butantan, Sao Paulo, Brazil Author Labarque, Facundo Museo Argentino de Ciencias Naturales, Buenos Aires ,, text ZooKeys 2009 2009-07-29 16 16 115 147 journal article 10.3897/zookeys.16.236 bce38a29-3fdd-4d4b-a5df-1ccf3b44b71c 1313–2970 576479 1DBBDBA2-6036-4675-984F-E640BC2A1575 Sparianthina sp. Figs 50-54 Material examined. 1 ♀ ( PJ 1667), French Guyana , Cayenne, R. Yelski leg, U. Taczanovski det. sub Sparassus sp. ( MZPW ). Figures 50-54. Sparianthina sp. from French Guyana ( ♀ MZPW , PJ 1667) 50 Epigyne, ventral 5 1 Internal duct system, dorsal 52 Chelicerae, ventral 53 Eyes, dorsal 54 Right leg III, retrolateral. Note . The copulatory organ of this female is very similar to that of S. rufescens comb. n. , but differs in the orientation of the epigynal furrows (almost parallel and only slightly bent), in the shape of the glandular appendages (narrow and almost parallel, tip only slightly widened), and in having two short dorsal tibial spines on all legs. It is not described here as a new species, as intraspecific variation in this genus is not known. Conspecific males should help to characterise this form.
