LEAFHOPPER SUBFAMILY NEOCOELIDIINAE — KRAMER 273 



Neocoelidiana DeLong 



Figures 81-86 



Neocoelidiana DeLong 1953, p. 122. Type of genus Neocoelidia ohscura Baker 

 by original designation. 



Description. — With carina separating face and crown. Crown in 

 dorsal view wider than long, very broadly or bluntly angled apically, 

 and produced beyond eyes. Head including eyes narrower than 

 pronotum. Ocelli on anterior margin of crown. Antennae from half 

 to three-fourths as long as body including forewings. Posterior 

 margin of pronotum broadly and often sharply indented. Venation 

 of forewings highly obscure except apically. 



Ground color stramineous to yellow, often with tliree inconspicious 

 longitudinal stripes of slightly darker shade on crown and pronotum. 

 Apex of crown with black spot. Forewings yellowish hyaline, at 

 times with few additional brown marldngs or tinges, with veins 

 concolorous. 



Male genitalia: Valve lacldng. Male plates fused basally for 

 more than half length, without short macrosetae apically. Pygofer in 

 lateral view with dorsal process and either ventral process or ventral 

 hook. Anal tube with single ventral hook. Connective broadly 

 Y-shaped. Apex of style strongly hooked in lateral view. Aedeagus 

 in lateral view approximately S-shaped, often somewhat twisted, and 

 with some sort of apical modifications. 



Discussion. — The genus as here defined contains seven species from 

 western United States and Mexico, all of which were treated by 

 DeLong (1953). The male genital structures of the type-species, 

 Neocoelidiana ohscura (Baker), are shown in figm-es 81-86.

Neocoelidiana subgenus Coelella DeLong 1953, p. 125. Type of subgenus 

 Neocoelidia distincta Oman by original designation. 



Description. — With carina separating face and crown. Crown 

 in dorsal view wider than long, bluntly angled apically, and produced 

 beyond eyes. Head including eyes narrower than pronotum. Ocelli 

 on anterior margin of crown. Antennae from half to three-fourths 

 as long as body including forewings. Posterior margin of pronotum 

 broadly and sharply indented. Venation of forewing highly distinct. 



Ground color stramineous to yellow, usually with three more or less 

 well-defined longitudinal stripes of slightly darker hue on crown and
