Diagnosis

Females are most similar to E. jugicola . Mesepisternum is (usually?) extensively pale and black colour on abdominal terga decreases gradually from base to apex in E. hypoxantha , while mesepisternum is (usually?) black, and black colour on terga decreases abruptly from base to apex in E. jugicola . Also, the abdomen can be green in living E. hypoxantha females, but pink in E. jugicola . Details of the lancet (setae long and hair-like, all visible sutures in dorsal part inclined basally) and colouration (pale and round pterostigma, pale mesepisternum) should distinguish the species from the other Euura which have a lancet with the radix longer or about as long as lamnium. Males are extensively pale and have distinctive penis valves, with a large valvispina and a distinct hump dorsobasally.
