Measurements (in mm) (3 individuals). Body length 1.1–1.2 mm; length of forewing pad 0.57–0.62.

Etymology. Named after Jonathan Molina Hernández, who collected part of the type series.

Host plant CI. Withania aristata (Solanaceae) .

Distribution CI. Tenerife.

Biology. The immatures induce pit galls in leaves ( Figs 294–296 ) in which they develop. Each gall can contain one to five immatures. Immatures are sometimes parasitized ( Fig. 293 ) by eulophid wasps ( Hymenoptera : Eulophidae ), adults and immatures by ectoparasitic mites (Prostigmata: Trombidiidae ).

Comments. The males of Drepanoza molinai and D. montanetana (see Aguiar 2001 for the description and illustrations of the latter) share similarly shaped head, forewing and terminalia. Drepanoza molinai differs from the latter in having a more strongly curved ‘head’ of the distal segment of the aedeagus and a less curved-back paramere. In the female terminalia, D. molinai resembles D. fernandesi and D. lienhardi but differs from them in having an apically narrowly rounded forewing (rather than pointed). It differs from D. fernandesi also in having a sinuate circumanal ring, longer genal processes and a slightly curved paramere, and from D. lienhardi in having a backwards-bent paramere (relatively straight in D. lienhardi ).
