Diagnosis

External characters are not sufficient for the identification of this species. In the male genitalia, Dishkeya gouaniae resembles the Nearctic D. bifurcata (Braun, 1915); however, D. gouaniae is distinguishable from the latter by its widely rounded vinculum, spiny juxta and slender apical processes of the phallus. The host plant, Gouania polygama (Jacq.) Urb. ( Rhamnaceae Juss. ), makes D. gouaniae exceptional among all other Tischeriidae (the related D. bifurcata feeds on Ceanothus, another genus of Rhamnaceae ).

Description

This species was described and illustrated by Stonis & Diškus (2007: 1287–1291, figs 2, 3a–c, 4a–b).

Biology

Host plant: Gouania polygama (Jacq.) Urb. (Rhamnaceae) . Larvae mine leaves in March–July and September. The leaf mine has a linear or corridor shape (not preserved by the collector with the reared specimens, and therefore not studied in detail). This species was listed as ‘ Tischeria sp. 12’ by Lewis et al. (2002). Of 25 living mines reared successfully, 14 (56%) were parasitised.

Flight period

Based on reared specimens, adults occur during March–September.

Distribution

Currently known only from a single locality in Belize (Las Cuevas), at an elevation of about 550 m.
