SE. of Potrero Grande, on Rio Coto Brus. Goemans (2016) also lists a male collected at Brownsberg National Parc, Suriname expanding the range out of French Guiana and into Suriname. This specimen is why the new species is described in this work even though the majority of specimens were collected in French Guiana.

Etymology. The name is a combination of guyan -and - ensis (L., suffix denoting place, locality) in reference to the distribution of the species in French Guiana ( Guyane in French) and Suriname (formerly Dutch Guiana).

Remarks. Goemans (2016) identified the taxon previously identified as Zammara brevis ( Distant, 1905a) and Zammara eximia ( Erichson, 1848) from French Guiana as a new species but has not published a formal description in five years so I am using this opportunity to validate the taxon using a series of specimens provided by SEAG. Goemans (2016) disclaimed all taxonomic actions of the dissertation for nomenclatural purposes as recommended by Article 8 of the International Code of Zoological Nomenclature (ICZN 1999) but I conserve the name he proposed here as I have done when validating other unofficial taxa (e.g. Sanborn 2005; Sanborn et al. 2008).

Goemans (2016) also determined that the true Zammara eximia has three-segmented tarsi so it cannot be a member of the genus Zammara nor the specimens previously determined as the species inhabiting French Guiana. As a result, he proposed to transfer the species to Zammaralna Boulard & Sueur, 1996 . I take this opportunity to reassign the species to Zammaralna officially to become Zammaralna eximia ( Erichson, 1848) n. comb. since it supports the erection of the new species. In addition, Zammaralna eximia ( Erichson, 1848) n. comb. has a more westerly distribution than the new species with specimens being confirmed from Guyana and Venezuela ( Goemans 2016) further supporting the idea it is a distinct taxon from the new species.

Measurements (mm). N = ten males or seven females, mean (range). Length of body: males 24.56 (22.5526.35), females 25.86 (23.90–27.30); length of fore wing: males 32.01 (29.25–33.90), females 34.71 (32.80–36.05); width of fore wing: males 10.73 (10.15–11.50), females 11.44 (11.00–11.70); length of head: males 4.21 (4.004.40), females 4.29 (4.15–4.40); width of head including eyes: males 7.76 (7.35–8.35), females 8.15 (7.70–8.60); width of pronotum including suprahumeral plates: males 12.04 (10.45–13.00), females 12.76 (11.60–13.35); width of mesonotum: males 8.50 (7.90–9.05), females 8.81 (8.15–9.40).

Diagnosis. Zammara guyanensis n. sp. can be distinguished from the majority of species of Zammara by the small body size (wingspan <80 mm), ratio of head width to pronotum width, and the pattern of infuscation in the fore wing. Only Z. calochroma Walker, 1858a , Z. olivacea Sanborn, 2004 , and Z. smaragdula Walker, 1858b are of similar body size to Z. guyanensis n. sp. but all can be distinguished by possessing a spot of infuscation on the fore wing cubitus anterior 1 that is lacking in the new species ( Goemans 2016). The ratio of the head width to the pronotum width is about 0.64 in Z. guyanensis n. sp., 0.75 in Z. calochroma , 0.70 Z. olivacea and 0.75 Z. smaragdula ( Goemans 2016) further distinguishing these species from Z. guyanensis n. sp. Thouvenot (2007) illustrates the variability in the fore wing infuscation pattern found in the species.

Distribution. The species is known from a number of localities across French Guiana and a single specimen from Suriname ( Goemans 2016, present study).
