Song, Zhi-Shun, Malenovský, Igor & Liang, Ai-Ping, 2016, Revision of the Afrotropical genus Fernandea Melichar, 1912 (Hemiptera: Fulgoromorpha: Dictyopharidae), with description of a new species from Equatorial Guinea, Zootaxa 4139 (1), pp. 106-116 : 113

Fernandea latifemorata sp. nov.

( Figs 1 C, 2B, 5)

Diagnosis. The new species can be distinguished from F. conradti by the broader fore femora and the aedeagus with shorter and smaller dorsolateral lobes of the phallobase.

Description (♂ only). Body length (from apex of head to tip of forewings): 7.1 mm; head length (from apex to base of eyes): 0.9 mm; head width (including eyes): 1.3 mm; vertex width: 0.4 mm; forewing length: 5.5 mm.

Coloration largely identical to F. conradti , but pronotum and mesonotum much paler, less reddish ochraceous, with a pair of longitudinal dark brown streaks along median carina, respectively ( Fig. 1 C, 5A).

Male terminalia with pygofer narrow and elongate, ventrally slightly wider than dorsally (about 1.5:1); posterior margin distinctly convex subapically in lateral view ( Fig. 5 E). Aedeagus ( Fig. 5 H–I) large and robust, with a pair of long endosomal processes curved in middle and directed dorsad, apex acute and pigmented; phallobase with membranous and inflated lobes: one pair of dorsolateral lobes short and broad, directed posteriad, apex without spines; the other pair of ventral lobes tapering and directed posteriad, apex with numerous small and short spines. Segment X large and relatively elongate in dorsal view ( Fig. 5 D), ratio of length to width near middle about 1.7:1.

Material examined. Holotype: Ƌ, [ EQUATORIAL GUINEA]: Span. Guinea, Nkolentangan, 7.XI–8.V, G. Teßmann ( MFNB).

Etymology. The specific epithet is an adjective derived from the Latin words latus (= wide, broad) and femur (= thigh). The new species is named for its greatly flattened, dilated, and foliaceous fore femora.

Distribution. Equatorial Guinea.

Remarks. The holotype was evidently collected during the expedition by German ethnologist, explorer and collector Günter Tessmann (1884–1969) to the Fang people which took place in 1907–1909. According to Tessmann (1913), the base camp of Nkolentangan was located near “Alén”, lying probably inside or close to what is today the Monte Alén National Park in mainland Equatorial Guinea (central coordinates 1°31′48″N, 10°6′36″E), an area covered with primary rainforest over an altitudinal range of 300–1250 m.
