Clito trinidadensis, Cock, 1998

Grishin, Nick V., 2014, Two new species of Clito from South America and a revision of the Clito littera group (Lepidoptera: Hesperiidae: Pyrginae), Zootaxa 3861 (3), pp. 231-248 : 238

C. trinidadensis Cock, 1998

( Figs. 17–18 , 26 e–f, 27 part, 28 part)

The most recently described species, C. trinidadensis from Trinidad ( Figs. 17–18 , 26 e–f, 27 part), is more similar in genitalia to C. nebulosa , but differs from it in a narrower valva, slightly more prominent distal bulge on the cucullus and darker wing patterns with differently shaped spots. It is a darker species, with largely brown hindwing. Basal edge of forewing discal cell pale spot in C. trinidadensis is straight or rounded, angled to the costa ( Figs. 17–18 , 27 part).

Addition of the last two species increases the species count in the C. littera group to five. In addition to this work, primary types and other specimens of all these species are illustrated in Warren et al. (2014). Further inspection of Clito specimens from the C. littera group in USNM collection revealed material from Ecuador and Venezuela that could not be attributed to any of these species due to differences in genitalia. One of these new species appears to be closer to C. jonkersi , and the other is more similar to C. littera . These two species are named below.

FIGURE 27. Visual keys to species in the Clito littera group. Dorsal and ventral aspects for each species are shown on the left and right of the species name, respectively. Images shown are illustrations, sometimes composed of photographic segments from left and right sides and digitally edited to highlight the wing patterns instead of imperfections in specimens. Images are set to be approximately the same size. Unedited and to scale photographs of specimens are shown in Figs. 1 – 20. Since these species are defined on the basis of male genitalia, which are likely to be diagnostic, wing pattern characters are preliminary due to exceedingly small samples of available specimens, and exceptions are expected. Wing pattern characters should be treated as suggestions for further research. Photographs of C. jonkersi and C. nebulosa are by Bernard Hermier and Ernst Brockmann, respectively.

C. nebulosa original illustration of the holotype from Draudt (1924) dorsal side, half-specimen image is shown for easy comparison on 23. (and Figs. 15 – 16). Dorsal and ventral surfaces are shown on odd- and even-numbered figures, respectively, except illustrations. Labels are shown between the specimen images. Labels are reduced 2.5 times compared to specimens: small scale bar below C. trinidadensis locality labels refers to labels, and larger scale bars refer to specimens.
