Type locality. Bugaba , Panama.

Type material. Lectotype ♀ ( Fig. 86 View FIGURES 86 – 88 ) and paralectotypes 2♀ ( Figs. 89, 90 View FIGURES 89 – 90 ), here designated. The specimens are deposited in BMNH under the numbers 0 10392177, 0 10392218 and 0 10392219, respectively. Lectotype labels: “ Bugaba \ Panama \ Champion\\B.C.A.Homopt. \ Fidicina \ fumea \Dist.\\BMNH(E)\1326030\\ Fidicina \ fumea Dist. ” and “type” . Paralectotypes labels: “ Bugaba \ Panama \ Champion\\ fumea \Dist.\\Distant coll.\1911-383\\“syntype”; “Bugaba\ Panama\ Champion\\ fumea \Dist.\\“syntype”.

Remarks: The species was assigned to Fidicinoides ( Sanborn et al. 2008) due to “the small lateral metascutellar plates (more obvious in males), the small dorso-lateral opening to the timbal chamber, the scutellum with a smooth lateral surface, and eyes not exceeding the breadth of the suprahumeral lobes of the pronotum”. However, the species possesses 3-segmented tarsi and should be classified in the subtribe Guyalnina Boulard & Martinelli, 1996. Fidicinoides fumea has elliptical eyes, the medial margin of the timbal cover partly covering the timbals, the uncus and theca very similar to those of G. bonaerensis and to the seven new species here described. Therefore, the species is transferred to Guyalna , redescribed and the male genitalia are described for the first time.

Diagnosis. The species can be distinguished from all other species of Guyalna by the anteromedian margin of the operculum inclined, the wings smoky apically, the uncus with lateral margin convex, the median uncus lobe with the posterior margin slightly bifurcated, the lateral uncus lobes large expanded laterally with the posterior margin obtuse, and the internal margin obtuse and wide. This species has a similar morphology to G. rufapicalis and G. maxineae but can be distinguished by the shape of the uncus and theca.

Color. Head, pronotum and mesonotum olive green stained in black. Clavus and base of cubital cell in fore wings, and basal area in hind wings brownish. Legs brownish. Abdomen dark brown. Thorax and abdomen dark brown ventrally.

Description. Head ( Fig. 91 View FIGURES 91 – 97 ) including eyes, broader than pronotum (except the pronotal collar) and mesonotum. Vertex with large longitudinal black band covering majority vertex reaching the area behind eyes, supra-antennal plates and apex of postclypeus. Elliptical eyes projecting laterally beyond anterior angles of pronotum, internal margin of eyes almost tangent to imaginary line continued from the lateral fissure of pronotum. Area behind eyes with setae. Lateral ocelli widely separated, distance between them equivalent to distance between each lateral ocellus and eye. Lateral ocelli higher than median ocellus in frontal view. Antenna brown. Postclypeus ( Fig. 87 View FIGURES 86 – 88 ) with thirteen transverse ridges, slightly salient in lateral and dorsal view (apex slightly prominent in dorsal view relative to supra-antennal plates), oval in ventral view. Central sulcus slender. Space between transverse grooves golden. Anteclypeus and carina black. Lorum black with setae. Rostrum with tawny mentum and labium. Labium short, reaching the posterior margin of basisternum 3, black at apex.

Pronotum ( Fig. 91 View FIGURES 91 – 97 ) narrower than mesonotum (except pronotal collar) with black band in ambient fissure. Anterior margin stained in black. Paranota narrow and straight, visible in dorsal view. Mesonotum ( Fig. 91 View FIGURES 91 – 97 ) with submedian and lateral sigillae stained in black. Lozenge-shaped black band between sigillae reaching the scutellum. Scutal depression black. Scutellum with posterior projections forming an acute angle, apices slightly pointed, with blond setae. Epimeral lobe not reaching the anteromedian margin of operculum. Anepimeron 2 and epimeral lobel of same length. Basisternum 3 ( Fig. 92 View FIGURES 91 – 97 ) with well-developed protuberances relative to median insertion, developed laterally, protuberances apices spaced, anterior margin of basisternum 3 straight, posterior margin straight. Operculum ( Fig. 93 View FIGURES 91 – 97 ) triangular with apex almost closing tympanal cavity, the anteromedian margin inclined, lateral margin concave anteriorly becoming linear posteriorly, posterior margin linear, internal angles closely separated but not touching. Meracanthus long, reaches the posterior opercular margin. Gutter present only on lateral margin of operculum. Profemora armed with three spines, primary round at apex and leaning forward, secondary sharp and straight, apical straight and shorter than others. Three segmented tarsi. Wings hyaline, smoky apically. Fore wings with median vein divergent to cubitus anterior vein, median vein short before bifurcation, basal cell entirely opaque, apical cell 2 shorter than 1 and 3, medial crossvein oblique. Hind wings with basal area brownish, radius vein straight.

Abdomen subcylindrical, length equivalent to combined length of head and thorax in dorsal view. Timbal cover ( Fig. 88 View FIGURES 86 – 88 ) tumid, rounded apex reaching the lateral metascutellar plate, medial margin concave partly covering timbals. Sternite I not visible in ventral view. Posterior margin of sternite II concave. Median projection of sternite II near metacoxa. Sternite VII ( Fig. 94 View FIGURES 91 – 97 ) sub-rectangular, lateral margin straight becoming concave apically and emarginate, posterior margin emarginate forming two obtuse apices. Sternite VIII ogive-shaped.

Pygofer ( Fig. 95 View FIGURES 91 – 97 ) with rounded distal shoulder. Basal lobe of pygofer short, not reaching the lateral uncus lobes, and not delimited with lateral margin of pygofer. Uncus ( Fig. 109 View FIGURES 101 – 109 ) without spines, with lateral margin convex. Median uncus lobe triangular, posterior margin slightly bifurcated, lateral margin convex in ventral view. Lateral uncus lobes large expanded laterally, posterior margin obtuse, internal margin obtuse and widely separated in ventral view. Lateral uncus lobes elongated in posterior view. Protuberance of basal plate distant from apex of basal lobe. Basal curve of aedeagus short, near to lateral lobes. Theca ( Figs. 96, 97 View FIGURES 91 – 97 ) dorsally developed forming a horn attached to vesica and extending beyond apex. Vesica originates in fissure at theca, extruded at apex with cornuti on inner surface.

Female. Present same somatic characteristics of male except operculum ( Fig. 98 View FIGURES 98 – 100 ) smaller, posterior margin straight, the lateral margin convex, meracanthus over internal angle. Sternite VII ( Fig. 99 View FIGURES 98 – 100 ) longer, sub-rectangular, posterior margin straight, directed anteromedially to wide and truncated middle groove. Ovipositor sheath extending same distance as tip of dorsal beak. Ovipositor ( Fig. 100 View FIGURES 98 – 100 ) with eight teeth.
