( Figs. 4‒ 5 )

Type specimen. Holotype: ♂ French Guiana, falls near Camp Patawa , Kaw Mountain, 4.54465ºN, 52.15258ºW. 177 m. 16- V.2006. C. R. Nelson coll ( BMNH)

Description. Male. General coloration black and brown. Vertex, fastigium, pronotal disk and terminalia brown, the rest of the body black with small whitish points, two last antennal segments and first half of the tarsi white ( Fig. 4 ). Whitish eyes and ocelli (possibly different in life). Hind wings black with brown venation. Head: eyes occupying a quarter of the cephalic capsule, fastigium of the vertex undulated in dorsal view and little prolongated in side-view ( Fig. 5A ). Pronotum mostly flat, extending beyond the tip of the abdomen and overcoming noticeably the length of the hind femora ( Fig. 5B ), with a small undulation at the level of the mesothorax; lateral lobes of the pronotum a little wider than long; lateral shoulder carina rounded and moderately prolonged ( Fig. 4 ). Wings. Tegmina lanceolate, extending to the apex of metathorax ( Fig. 4A ). Legs slender, moderately long; hind femora with dorsal edge serrulated and the pre-genicular spine little-developed. Abdomen. Subgenital plate slender mid-sized with the dorsal edge straight, apex divided; epiproct ovoid longer than wide; cerci conical; penultimate abdominal sternite straight.

Female. Unknown.

Measurements (in mm): CFP: 11.2. PL: 10.5. PLB: 1.3. FF: 2.3. FL: 2. MFL: 2.2. MTL: 2.4. HL: 4.2. HW: 1.5. HL: 3.8.

Distribution. Only known from the type locality.

Etymology. In memory of the maroon slaves who inhabited French Guyana. At present, their descendants still inhabit the territory, as free people, although they are still recognized as maroons.

Comparison. This is the second known species for Phelene stat. resurr., differs from P. turgida mainly by its coloration, P. maroon n. sp. is predominantly black ( Figs. 4 , 5 ) in contrast to P. turgida which is brown ( Figs. 2 , 3 ). On the other hand, P. turgida has a hump on the pronotal disc, at the level of the mesothorax ( Figs. 2A, B , 3B ), and a moderately developed, triangular-shaped, and not pointed spine on the lateral lobe of the pronotum ( Fig. 2C ). In contrast, the new species does not have the hump on the pronotal disc, they only have a little undulation at the level of the mesothorax ( Figs. 4A, B ), and the lower edge of the lateral lobe of the pronotum is rounded and poorly expanded to the sides ( Fig. 5B ).
