Dendrocoris arizonensis Barber 1911 ( Figure 11)

Diagnosis. Vertex of head flat. Juga contiguous before tylus. Cicatrices concolorous with pronotal disk. Anterolateral pronotal inargins straight to nearly straight in dorsal view. Humeral angles prominent. Abdominal tubercle present in both sexes but very small in males. Legs immaculate. Abdominal spiracles variable, concolorous with venter or darkened. Veins of hemelytral membrane simple or furcate,not reticulate. Posterior aspect of male pygophore without teeth attending medial emargination. Paramere terminatingin long ental and short ectal digit ( Fig. 11).

Distribution. USA: Arizona, California, New Mexico, Texas. MEXICO: Nuevo Leon, San Luis Potosi, Durango.

Remarks. Nelson (1955) cites several records for oak. Mexican specimens are likelyto be confused with D. suffultus. The primary separation is the form of the male paramere. The species is widespread but limited to mountain habitats surrounded by desert. Because of this disjunct distribution it is not surprising that considerable morphological variation exists. Typical specimens have straight anterolateral pronotal margins and the spiracles concolorous with the venter.
