Quadrastichus erythrinae

An inverted triangle or "V" shaped region extending from the anterior border to the midlobe of the mesoscutum is dark brown, with the remaining portion being yellow.

The front part of the metasoma is pale, while the remaining portion is dark brown.

The female induces galls in the leaves, shoots, petioles and inflorescences of the plant.

During the development of the gall, the affected organ is deformed, and the petioles and shoots become swollen.

First collected in Florida on coral trees Erythrina variegata, now in Miami and Hawaii; also known from Singapore, Mauritius and Reunion, Taiwan, Hong Kong, China, India, Thailand, Philippines, American Samoa, Guam and in the Amami Islands and Okinawa in Japan.
