Abbrosoga multispinosa Otero and Bartlett, 2019

Plant associations

None reported. Caldwell and Martorell (1951) reported that all specimens of A. errata were collected above 2000 ft. Abbrosoga multispinosa is from low elevations.

Economic Importance

Limited, rarely collected.


This genus may be related to Anchidelphax, but the male lacks the posterior-projected extensions of the lateral margins of the pygofer opening.  It is similar to Anchidelphax in coloration (pale, weak median vitta on mesonotum, etc.), general build, and some features of the genitalia.  In Abbrosoga, the aedeagus is curiously bifed (unlike Anchidelphax), with the main part strongly downcurved. Abdominal segment 10 (the anal tube) lacks processes.

Few specimens of this species are known and the genus has not been reported outside of Puerto Rico.  I have specimens that may be this genus from Costa Rica.

The genus is in some ways reminiscent of the Tropidocephalini, but the calcar has teeth.
