Cylapus Say, 1832

Diagnosis. In addition to the characters provided by Wolski (2017), this genus can be easily distinguished from other members of the Cylapus complex by the following features of the female genitalia presented below.

Female genitalia. Bursa copulatrix trapezoidal ( Figs 16a, d, g , 17a, j ), rarely semicircular (17c, g); sclerotized rings usually unpaired or rarely paired, narrow, embracing anterior and lateral margins of bursa copulatrix ( Figs 16a, d, g , 17a, d, h, k ); dorsal sac sclerotized, with a more or less developed, transverse sclerotization connecting posterior portion(s) of sclerotized ring(s) ( Figs 16a, b, d, e, g, h , 17a, f, h, k ); ventral labiate plate broad, with stripe-like sclerotization ( Figs 16c, f, i , 17e, i, m ); posterior wall of bursa copulatrix membranous ( Fig. 19g ).

Remarks. The results of the present phylogenetic analyses fully corroborate my previous observation ( Wolski 2017) that the genus Cylapocerus Carvalho & Fontes should be treated as a synonym of Cylapus . The most distinctive features allowing for distinguishing Cylapus from other members of the Cylapus complex are: the metathoracic ostiolar canal strongly raised above the evaporative areas, the ostiolar peritreme arcuate and sharply pointed ( Fig. 10c ), tarsomere I as long as or weakly longer than II and III combined ( Fig. 10i ), the endosoma usually with at least four sclerites ( Wolski 2017: figs 66, 71, 80, 85, 97, 102, 110, 135, 140); the bursa copulatrix trapezoidal, rarely semicircular; the sclerotized rings thin, embracing the bursa copulatrix, the posterior edge (sac) of bursa copulatrix strongly sclerotized and with more or less developed transverse sclerite connecting posterior portions of sclerotized rings; vlp with a narrow, stripe-like sclerotization ( Figs 16 , 17 ).

Citation for the genus and treated species were given by Carvalho (1957), Schuh (2002 –2013), Gorczyca (2006a), and Wolski (2017).
