Additional material examined. PANAMA, Provincia Chiriquí: Reserva Forestal Fortuna , Sendero Quebrada Honda. 8.750083, -82.239083. 3 JUV. 19–24.vi.2008. L. Benavides, F. Labarque, L. Piacentini leg. (GWU-GH868, GH874, GH875).

Etymology. The species epithet is a noun in apposition taken from the type locality.

Diagnosis. Gelanor fortuna can be distinguished from congeners by its cephalothorax with two lateral dark stripes running from lateral eyes to cephalothorax apex more visible in females than in males, not present in other Gelanor species ( Figs. 23 A, 24A); cymbial flap with small indentations towards its apex, ( Figs. 23 E, G); epigynal septum rectangular as in G. innominatus but wider anteriorly and constricting posteriorly as in an inverted trapezium ( Figs. 24 F–G).

Description. Male holotype. Habitus as in Figs. 23 A–D. Total length 4.16; cephalothorax 2.37 long, 1.77 wide, 1.04 high; abdomen 1.79 long, 1.34 wide, 0.84 high. Carapace pale yellow, with two dark brown stripes running diagonally from anterior lateral margin towards cephalothorax apex ( Fig. 23 A). Sternum whitish, 1.23 long, 0.94 wide. Labium darker than sternum, 0.27 long, 0.22 wide. Clypeus 0.13 high; AME inter-distance 0.21, PME 0.07. PME–AME distance 0.21; AME–ALE 0.23; PME–PLE 0.29. Chelicerae pale yellow, with orange distal margins ( Fig 24 D); ChL 0.84; ChW1 0.39; ChW2 0.41. Abdomen cylindrical, white dorsally and pale yellow ventrally, with a red mark close to spinnerets ( Figs. 23 A–C). Cymbium almost as long as is wide (0.58 long, 0.62 wide); cymbial flap with small indentations towards its apex ( Figs. 23 E,G). Female paratype. Habitus as in Figs. 24 A–D. Total length 5.19; cephalothorax 2.67 long, 2.07 wide, 1.09 high; abdomen 2.52 long, 3.06 wide, 2.14 high. Carapace as in male ( Figs. 24 A, D), wider than in the male. Sternum whitish, 1.23 long, 0.94 wide. ( Fig. 24 C). Labium 0.27 long, 0.22 wide. Clypeus 0.13 high; AME inter-distance 0.21, PME 0.07. PME–AME distance 0.21; AME–ALE 0.23; PME–PLE 0.29. ChL 0.84; ChW1 0.39; ChW2 0.41. Abdomen pink anteriorly, anterior spots white, longer than wide with two smaller white spots above them; spots without dark red margins. Abdomen posterior half whitish with eight red thin lines crossing transversally from side to side. Epigynal septum wider anteriorly and constricting posteriorly as in an inverted trapezium; septum lateral anterior lobes small, with rounded edges ( Figs. 24 F, I). Spermathecae rounded; less than one spermatheca diameter apart, not externally fused ( Figs. 24 J– K). Variation. Unknown, only two adult specimens available for study.

Distribution. Known only form its type locality in Panama ( Fig. 26 ).
