038487AFFF83E342FE1DFCFAFC7B1BF5.taxon	discussion	Comments. This species is very similar to A. laminatus (Horváth, 1911). There are no clear habitus differences between both species, possibly except body size and differences in the shape of the paranota. According to HORVÁTH (1911), A. mayri is smaller and the paranota are a little shorter. In addition, both species are distributed in the same area. Further studies are needed to clarify the systematics of the genus Ammianus Distant, 1903. Ammianus mayri is known from Cameroon, Ivory Coast, Benin, Guinea, and Uganda (DRAKE & RUHOFF 1965, GÖLLNER- SCHEIDING 2003). It was already collected in Gabon in Mont de Cristal near Komo and in the Mondah forest near Libreville but never formally mentioned from the country. These are the first records from the Ipassa Reserve and Makoku.	en	Guilbert, Eric, Cnrs, Cp, Département de Systématique et Evolution - (2008): New data on the Tingidae from Gabon (Hemiptera: Heteroptera).

038487AFFF83E340FE4CFA44FEF31E6E.taxon	diagnosis	Differential diagnosis. The genus Cysteochila is diverse and widespread. It includes 80 species in Africa and Madagascar (GUILBERT, unpubl. data) and exhibits a great variety of combination of characters, which makes the systematics of the genus difficult and confused. Cysteochila collarti was until now the only species of the genus known in Gabon. Cysteochila stysi sp. nov. is mostly similar to C. collarti but differs by the paranota wider and in contact with the lateral carinae (the paranota do not reach the carinae in C. collarti). Other species can be distinguished from the new one as follows. Cysteochila kalongensis Duarte Rodrigues, 1982, is close to C. stysi sp. nov. as well but differs from it by the paranota not reaching the lateral carinae and by the two rows of areolae on the costal area not being regular. Cysteochila manselli Duarte Rodrigues, 1981, has also two rows of areolae on the costal area but its paranota are much wider and cover the lateral carinae. Cysteochila tonkouiana Duarte Rodrigues, 1981, has also biseriate costal area, but the paranota are in contact with the lateral carinae only near the calli. Cysteochila impressa Horváth, 1910, has paranota of the same shape but larger and with fewer areolae than in C. stysi sp. nov., and the costal area uniseriate posteriorly on a longer length, while C. stysi sp. nov. has only the very posterior part uniseriate. In addition, the areolae on the costal area of C. impressa are larger than in C. stysi sp. nov. Finally, C. biseriata Schouteden, 1916, has a biseriate costal area but paranota of a different shape and C. mokuensis Schouteden, 1953, has paranota surpassing the lateral carinae.	en	Guilbert, Eric, Cnrs, Cp, Département de Systématique et Evolution - (2008): New data on the Tingidae from Gabon (Hemiptera: Heteroptera).
