Antillopsyche mexicana , new species

Figs. 5–6

Antillopsyche mexicana differs from all other recent and fossil species by the forked pair of long spines of tergum X. In the hind wing apical fork 3 is very short compared with those of all other fossil species from Dominican amber.

Adult. Length of forewing 3.9 mm (holotype), 3.6 mm (paratype). General structure and forewing and hind wing venation typical for genus ( Figs. 5 , 6 A),in hind wing fork 3 is remarkably short compared with other fossil species from Dominican amber.

Male genitalia ( Figs. 6 C, 6D). Tergum IX in lateral view with preanal appendage apically rounded, more than 2 times as long as wide, flat. Tergum X with mesal process deeply forked into 2 elongate lobes, as long as the apex of preanal appendage. Inferior appendage oval, approximately as long as preanal appendage, with acuminate basodorsal appendage, bent mesad. Apices of lobes of tergum X, preanal appendages, and inferior appendages all extend equally far posteriad, and are slightly surpassed by phallus ( Fig. 6 C). Phallus jacketed by laterodorsal membrane, apex membranous, without cluster of spines

Holotype male: Embedded in Mexican amber together with another male (paratype) and in the amber collection of the Instituto de Historia Natural y Ecologia, Museum of Paleontology, Tuxtla Gutiérrez, Chiapas, collection no.: IHNFA 232.

Paratype: Embedded in Mexican amber together with the holotype, in the amber collection of the Instituto de Historia Natural y Ecologia, Museum of Paleontology, Tuxtla Gutiérrez, Chiapas, collection no.: IHNFA 232, male.

Etymology. Named in recognition of the type country and the first evidence of the genus Antillopsyche in Mexico.
