LEAFHOPPER SUBFAMILY NEOCOELIDIINAE — KRAMER 267 



Discussion. — Megacoelidia contains only two known South Amer- 

 ican species, both of which appeared with the original generic descrip- 

 tion. The genus contains the largest members of the subfamily. 



Key to Species of Megacoelidia 



Dorsal markings consisting of single narrow black border on posterior margin of 

 pronotum and on apex of each forewing. Male plates in ventral view pointed 

 apically and aedeagus with long paired lateral processes (Brazil). 



M. splendida Kramer and Linnavuori 



Dorsal markings limited to single narrow black border on apex of each forewing. 

 Male plates in ventral view rounded apically and aedeagus with short paired 

 lateral processes (Bolivia) M. aurantia Kramer and Linnavuori 



Tozzita^ new genus 



Figures 45-49 



Type of genus Tozzita ips, new species. 



Description. — With slender but distinct carina separating face and 

 crown. Crown in dorsal view much longer than wide, bluntly angular 

 apically, and strongly produced beyond eyes. Ocelli near anterior 

 margin of crown but posterior to carina. Head including eyes dis- 

 tinctly narrower than pronotum. Posterior margin of pronotum 

 broadly indented. Antennae as long as body including forewings at 

 rest. Venation of forewings highly obscure except apically. 



Ground color stramineous to light brown without definite markings 

 except for black spot at apex of crown. Forewings stramineous 

 hyahne. 



Male genitalia. — Valve lacking. Male plates fused for nearly 

 entire length. Pygofer modified only dorsally with processes or exten- 

 sions. Anal tube with heavily sclerotized portions. Connective more 

 or less V-shaped and articulated with strongly asymmetrical aedeagus. 



Tozzita ips, new species 



Figures 45-49 



Length. — Male 6.75 mm. 



Coloration. — Stramineous with indefinite brownish areas on head 

 and thorax. Only distinct marking is black apical spot on crown. 

 Forewings stramineous hyaline. 



Male genitalia. — Capsule in ventral view with slight apical notch 

 on ventral cover which is exceeded by the pygofer (fig. 48). Capsule 

 in lateral view with few tiny spines on ventral margin of pygofer, 

 dorsum with blunt, sclerotized process; anal tube with two heavily 

 sclerotized plates, posterior one notched dorsally (fig. 45). Aedeagus 

 in ventral aspect slender and strongly asymmetrical (fig. 49), with 

 apex forked and gonopore opening on narrow mesal extension (fig. 46).
