First description of the male of Sphecotypus niger (Perty, 1833), with notes on behavioral and morphological mimicry (Araneae: Corinnidae: Castianeirinae) Author Leister, Matthew Author Miller, Kelly text Zootaxa 2014 3814 1 146 150 journal article 45564 10.11646/zootaxa.3814.1.10 c2f87315-8c22-4fba-87a2-55fa2f6526cd 1175-5326 230786 164387ED-CF6F-4AC2-97D5-E682BE1EB2FE Sphecotypus O. Pickard-Cambridge, 1895 Sphecotypus O. Pickard-Cambridge, 1895 : Type species, Sphecotypus formicarius O. Pickard-Cambridge, 1895 = S. niger ( Perty, 1833 ) . Diagnosis. Sphecotypus resembles Myrmecium Latreille, 1824 , in having deep constrictions on a narrowed carapace, but can be distinguished from this genus and other Castianeirinae by having: (1) only one deep constriction of the carapace, which is behind the cephalic region clearly separating the cephalic and thoracic regions; and (2) the prolongation of the sternum in front of the first coxae, producing a “neck” ( Fig. 1 A–C) ( Reiskind 1969 ; Deeleman-Reinhold 2001 ). In addition Sphecotypus differs from Myrmecium by having all coxae evenly spaced, and all emerging from beneath the thoracic region of the carapace ( Fig. 1 A–C), whereas the first two coxae in Myrmecium are spaced close to each other and emerge from beneath the cephalic region of the carapace ( O. Pickard-Cambridge 1895 ).
