Gonatocerus sp. near tuberculifemur (“Clade Y”)

Gonatocerus sp. ( tuberculifemur -like): de León et al. 2007: 73–75 (as “Clade Y”).

Material examined. ARGENTINA. Buenos Aires, Hurlingham, USDA, ARS SABCL, F8 progeny reared on eggs of T. rubromarginata, G. Logarzo , exposed 19–22.ii. 2007, emerged 3.iii.2007 (originally from: Tucumán, San Miguel de Tucumán, E. Virla, E. Luft Albarracin, from sentinel eggs of Hortensia similis (Walker) , exposed 14–15.xii.2006); colony originators: USA, California, Riverside Co., Riverside, UCR quarantine, sent 7.iii.2007 by G. Logarzo, arrived 9.iii.2007 (UCR quarantine S& R # 07–13–03), set up with eggs of Homalodisca vitripennis (Germar) on Euonymus japonica leaves 9.iii.2007 by S. Triapitsyn & V. Berezovskiy and preserved 19.iii.2007 by V. Berezovskiy [1 female, UCRC]. USA. California, Riverside Co., Riverside, UCR quarantine, F1 progeny, emerged 26–28.iii.2007, preserved 4.iv.2007 by V. Berezovskiy (from colony on eggs of H. vitripennis on Euonymus japonica leaves that was discontinued at F1, originally from Argentina, as listed above).

Diagnosis. Morphologically, both sexes of this form are virtually identical to G. tuberculifemur (“Clade X”) and G. sp. near tuberculifemur “Clade 1”, as described above.

Distribution. Argentina (Tucumán).

Natural host. Cicadellini : Hortensia similis (Walker) .

Factitious hosts. Proconiini : Homalodisca vitripennis (Germar) and Tapajosa rubromarginata (Signoret) .

Biology. Similar to that of G. sp. near tuberculifemur “Clade 1”, as reported by Virla et al. (2005).

Comments. The following slide-mounted specimen may also belong G. sp. near tuberculifemur “Clade Y”: Argentina, Tucumán, El Manantial, 30.xii.2004 – 3.i.2005, E. Luft Albarracin, ex. eggs of Plesiommata mollicella (Fowler) [1 female, UCRC].
