Remarks. Boulard (2001) references Fidicina mannifera (Fabricius, 1803) from French Guiana and Guadeloupe on page 80 of his work. He then states on page 83 that the homeland (“patrie”) of Fidicina mannifera remains uncertain. Considering that the specimens were provided a “few years” before the 1998 congress where the information was introduced (proceedings published in 2001), these specimens were likey in his possession prior to the publication of the work where multiple new species related to Fidicina mannifera was published (Boulard & Martinelli 1996). No specimens from Guadeloupe were included in the material examined for Fidicina mannifera and Guadeloupe was not included in the geographic distribution of the species in Boulard & Martinelli (1996). The specimens of Fidicina mannifera from Guadeloupe referenced in Boulard (2001) are, therefore, considered to be members of the new species described here.
The new species is similar in size and general appearance to Fidicina christinae Boulard & Martinelli, 1996, a species originally described from French Guiana but which has now been recorded from much of the South American continent (Boulard & Martinelli 1996; Sanborn 2011, 2019a, 2023a; Nunes et al. 2023). The shape of the opercula provides a rapid mechanism to distinguish the two species although there are a number of differences between the species (see diagnosis below).
Etymology. The name is a combination of guadeloup – (Guadaloupe, island in the West Indies) and – ensis (L., suffix denoting place, locality) in reference to the island of origin for the type series.

Measurements (mm). N = three males or three females, mean (range). Length of body: males 32.65 (31.40– 33.60), females 30.62 (29.75–31.90); length of fore wing: males 47.83 (47.00–49.00), females 45.77 (44.80–47.20); width of fore wing: males 15.78 (15.00–16.45), females 15.37 (15.00–15.80); length of head: males 5.43 (5.15–5.60), females 5.12 (5.00–5.20); width of head including eyes: males 14.37 (14.00–14.60), females 13.77 (13.55–13.95); width of pronotum including suprahumeral plates: males 15.15 (14.75–15.45), females 14.73 (14.50–15.10); width of mesonotum: males 13.30 (13.00–13.70), females 12.97 (12.70–13.20).
Diagnosis. Fidicina guadeloupensis n. sp. can be distinguished quickly from F. innotabilis (Walker, 1858c) and F.sawyeri Distant, 1912 by the lack of infuscation on the wing veins in these species. Similarly, the lack of infuscation on the ambient vien of the wings quickly distinguishes F. rosacordis (Walker, 1850) and the heavily pilose F. sciras (Walker, 1850). The red basal areas of the wings quickly distinguishes F. obscura Boulard & Martinelli, 1996, F. rosacordis (Walker, 1850), F. rubricata Distant, 1892b, and F. sawyeri Distant, 1912, while the orange basal areas of the wings distinguish F. muelleri Distant, 1892a, F. explanata Uhler, 1903, and F. vitellina (Jacobi, 1904) from the new species. The smaller size (body length less than 26 mm, wingspan less than 75 mm) distinguishes the Argentine F. affinis Haupt, 1918 and F. vitellina (Jacobi, 1904) from this larger new species, while the new species is smaller than F. ethelae (Goding, 1925) (body length about 40 mm, wingspan greater than 125 mm). The piceous abdomen with red posterior margins distinguishes F. robini Boulard & Martinelli, 1996 and F. umbrilinea (Walker, 1858c) from the new species, while green and red abdominal tergites distinguishes F. torresi Boulard & Martinelli, 1996. Similarly, the piceous abdomen distinguishes F. toulgoeti Boulard & Martinelli, 1996 from the new species.
The final two described species of the genus require additional analysis as they have a similar general appearance to the new species and one species was mistakenly used to identify examples of the new species in Boulard (2001). Fidicina mannifera differs in the head being noticeably wider than the anterior pronotum, the widest expansion of the costal margin is at the level of the proximal fore wing basal cell, the fore wings are about 2.75 times longer than wide (compared to about 3.03 in the new species), the fore wing medial crossvein is straight but the mediocubital crossvein is sinuate, the fore wing radiomedial and median crossveins are distinctly separated at the divergence of median vein 2, the fore wing radial and radiomedial crossveins are almost parallel, the length of fore wing apical cell 7 extends to the intersection of the medial crossvein and median vein 3, the opercula have a distinctive triangular extension on the posterolateral corner with the posterior margin distinctly angled near the middle (rather than a sinuate posterior margin), the abdomen is primarily piceous marked with castaneous, the lateral mesothorax and the abdomen have much denser pile, the uncal dorsal crest lacks a median, terminal curve, the uncal dorsal crest extends the same distance (longer in the new species) as the lateral branch of the uncus which has a smoothly curved ventrolateral margin and pointed ventral apophysis when viewed from the posterior (rather than the triangular ventrolateral margin and small knob-like ventral apophysis on the ventromedial margin in the new species), and female abdominal sternite VII with the posterior notch extending slightly beyond the posterior margin and small posterolateral extensions.
Fidicina christinae has the most similar general appearance to the new species. Fidicina christinae can be distinguished from the new species by the head being just wider than the anterior pronotum, the widest expansion of the costal margin is at the level of the proximal fore wing basal cell, both the fore wing median and mediocubital crossveins are distinctly sinuate (rather than slightly sinuate), the fore wing radiomedial and median crossveins are distinctly separated at the divergence of median vein 2 (rather than almost meeting at the divergence of median vein 2), the fore wing radiomedial crossvein is more obliquely oriented than the radial crossvein, the length of fore wing apical cell 7 extends to the intersection of the medial crossvein and median vein 3 (rather than the length of fore wing apical cell 7 being shorter than the intersection of the median crossvein and median vein 3), the opercula have a triangular shape (rather than a triangular posterolateral corner) with a concave posterior margin (rather than a sinuate posterior margin), the timbal covers are more inflated posterolaterally in the new species, the uncal dorsal crest lacks a median, terminal curve, the lateral branch of the uncus which has a smoothly curved ventrolateral margin and pointed ventral apophysis when viewed from the posterior (rather than the triangular ventrolateral margin and small knob-like ventral apophysis on the ventromedial margin in the new species), and the length of the transverse portion of the posterior margin of female abdominal sternite VII is longer than the width of the notch but about the same length in the new species.
Distribution. The species is currently known only from the type series collected on Basse Terre, Guadeloupe.
