N = three males or nine females, mean (range). Length of body: males 17.02 (15.5518.30), females 19.01 (17.80–19.85); length of fore wing: males 21.65 (19.80–23.15), females 23.29 (21.55–24.55); width of fore wing: males 6.82 (6.25–7.20), females 7.28 (6.80–7.65); length of head: males 2.57 (2.50–2.60), females 2.97 (2.75–3.10); width of head including eyes: males 5.62 (5.25–5.85), females 6.04 (5.70–6.55); width of pronotum including suprahumeral plates: males 6.82 (6.55–7.00), females 7.26 (6.70–7.65); width of mesonotum: males 5.65 (5.55–5.80), females 5.94 (5.40–6.20). Diagnosis. Proarna proximorubrovenosa n. sp. can be distinguished from the majority of species of Proarna by the body length being less than 20 mm and infuscation pattern of the fore wings. Proarna cocosensis Davis, 1935 is about the same body length as the new species but can be distinguished by the larger wing span (about 59 mm ), lacks the distal infuscation in the fore wing, and is restricted to Cocos Island west of Costa Rica . The new species can be distinguished from P. alalonga Sanborn & Heath, 2014 , P. championi Distant, 1881 , P. dactyliophora Berg, 1881 P. invaria ( Walker, 1850 ) , P. parva Sanborn & Heath, 2014 , and P. praegracilis Berg, 1881 by the lack of infuscation on the distal fore wing veins separating the apical cells and the generally smaller body sizes of these species. Proarna palisoti Metcalf, 1963a can be distinguished by the lack of wing infuscation and the white pubescent spots on the mesothorax at the base of the hind wing. Proarna strigicollis Jacobi, 1907 also lacks infuscation on the distal veins between the apical cells, has fore wings about 26 mm long, and a wing span greater than 55 mm . The primarily Caribbean ( Sanborn 2020e ) P. hilaris is very similar but can be distinguished from the new species by the green proximal wing venation, the reduced or absent infuscation on the nodal line, the lack of a spot on the postclypeus apex, the ventral margin of the timbal cover apical extension is parallel to the long body axis, the green and light castaneous ventral surface, the bulbous lateral female operculum, abdominal tergites green without castaneous markings forming stripes, the fore femur secondary spine is triangular and perpendicular to the femoral long axis, and the lateral branches of the uncus do not diverge as far nor curve laterally as far as they do in the new species.

Proarna proximorubrovenosa n. sp. : A, Holotype male and paratype female habitus; B, holotype male dorsum; C, holotype male timbal; D, holotype male operculum; E, paratype female operculum; F, holotype male lateral view of genitalia; G, holotype male posterior view of genitalia; H, paratype female lateral view of genitalia; I, paratype female ventral view of genitalia. Scale bar: A, 2 cm; B, 5 mm; C–E, 2 mm; F–G, 1 mm; H–I, 2 mm. The remaining two species of the genus are the other species of the genus known to inhabit Suriname . Proarna pulverea can be distinguished from P. proximorubrovenosa n. sp. by the posteriorly widening longitudinal fascia on either side of the pronotal midline, transverse abdominal fascia, lack of infuscation on proximal fore wing apical cell 1 and distal veins between apical cells, strongly curved origin of radius anterior 2, lack of curvature in distal veins separating apical cells, and the fore wing length about 2.9X width. Finally, the fore wing length is about 3.25X width, wing span about 64 mm , the strongly curved proximal costal margin, and fore wing apical cells longer than ulnar cells distinguish P. olivieri from this new species. Distribution. The species is known only from the type series collected in Zanderij, Para District , Suriname .
