Body length male 2.1-2.3 mm; female 2.2-2.4 mm. Vertex brownish-yellow, with one irregular spot near anterior margin (Fig. 1A and C). Face brownish-yellow, relatively long, with pale yellow anteclypeus oval-shaped contrasting face colouration (Fig. 1D). Pronotum with large brownish-yellow markings running at middle (Fig. 1C). Scutellum brownish-yellow (Fig. 1C). Forewing and hindwing almost transparent (Fig. 1A). Abdominal apodemes small, not extended beyond hind margin of 3rd sternite (Fig. 3G).

Male genitalia. Pygofer lobe with scattered microsetae at right edge. Dorsal pygofer appendage process without branch. Subgenital plate (Fig. 3B) broad sub-basally, provided with seven mid-length macrosetae on lateral surface centrally, several small fine setae scattered on apical area (Fig. 3B). Style apex with two terminal points, pre-apical lobe developed (Fig. 3D). Aedeagus with a pair of processes arising from apex of shaft; pre-atrium shorter than shaft, gonopore at subapex (Fig. 3E and F). Connective M-shaped (Fig. 3C).

The specific name is derived from the Latin word “dichotomus” (bifurcated), referring to the bifurcated processes on the aedeagal shaft in the ventral view (Fig. 3E and F).

Empoascanara dichotomus is characterised with the morphology of the genus Empoascanara as follows:

Crown fore margin strongly produced and angulate medially or weakly produced, broadly rounded apically. Vertex usually with pair of dark pre-apical spots or with large median apical patch. Pronotum pale or almost entirely dark or with dark posterior margin. Forewing with venation of clavum obscure.

Male pygofer lobe rounded or angulate, without dorsal macrosetae, with sparse long fine setae. Pygofer dorsal appendage movably articulated, ventral appendage absent. Subgenital plates free, lateral margin with angulate sub-basal projection, with 2–4 basal macrosetae and distinct marginal sub-basal rigid setae forming continuous row or with marginal sub-basal rigid setae restricted to basolateral angle. Style pre-apical lobe prominent. Style apex smooth, slender or truncate and expanded, third point absent. Aedeagus dorsal apodeme not expanded in lateral view; shaft curved dorsad, smooth or denticulate distally; apex broadened, truncate or acuminate in ventral view; ventral processes placed basally, well separated from shaft. Connective median anterior lobe broad, arms short.

Empoascanara dichotomus is similar to Empoascanara thomasi Dworakowska, 1979; however, the new species has an aedeagus with a pair of processes on the apex instead of on the subapex and processes apex branched and the more chitinised aedeagus.

Crown has anterior region yellow, while posterior area is yellow-milky, wider than pronotum. Face yellow, relatively long, with anteclypeus yellow (Fig. 2C). Pronotum milky yellow, without spots. Scutellum has anterior region yellow, while posterior area is yellow-milky. Border of forewings yellow, tinted with translucent centre (Fig. 2A and B). Male abdominal apodemes extended not beyond hind margin of 3rd sternite (Fig. 4H).

Male genitalia. Pygofer lobe with scattered microsetae at right edge (Fig. 4C). Dorsal pygofer appendage process without branch. Subgenital plate (Fig. 4A) broad sub-basally, provided with three long macrosetae on lateral surface centrally, several small fine setae scattered on apical area (Fig. 4C). Style apex truncate, pre-apical lobe developed (Fig. 4D). Aedeagus long, with one pair of processes arising from base of shaft; pre-atrium shorter than shaft (Fig. 4E and F). Connective arms short (Fig. 4G).

The specific name is derived from the Latin word “ramosis”, which means that species have two processes on the aedeagal shaft in the ventral side view (Fig. 4E).

The new species, Kapsa ramosis, has the following morphological characters that places it within the subgenus Kapsa (see also Song and Li 2012): Three macrosetae on the subgenital plate present (the subgenus Rigida has at least four macrosetae on the subgenital plate). Head is narrower than pronotum. Crown fore margin weakly produced, broadly rounded apically. Face depressed in profile, less than 45° from horizontal. Male anteclypeus narrow, depressed, as in female. Colour pattern brown. Vertex unicolorous or with pair of dark pre-apical spots or with median apical spot. Vertex mid-line pale or dark. Face without black spots anterodorsad of antennal pits. Anteclypeus pale, concolorous with rest of face or brown or black. Pronotum pale or with dark posterior margin. Mesonotum entirely pale or pale, with dark lateral triangles or entirely dark, apex concolorous with rest of mesonotum or apex dark, contrasting with adjacent pale areas. Thoracic ventre entirely pale or with dark mesosternum, remainder pale or entirely dark. Forewings without oblique vittae or with broken oblique vittae, without crossbands or with darkened apices, without numerous irregular red dots.

Male pygofer not extended to apex of subgenital plate. Pygofer lobe rounded. Pygofer ventro-apical membranous area well developed. Subgenital plate lateral margin with angulate sub-basal projection. Subgenital plates free. Style pre-apical lobe prominent. Style apex truncate and expanded or with 3 points. Aedeagus with pre-atrium shorter than shaft or with pre-atrium about as long as shaft. Aedeagus without dorsal process or with processes on dorsal apodeme. Connective median anterior lobe broad. Connective stem absent or very short, depressed.

Kapsa ramosis is similar to K. furcifrons (Jacobi, 1941), but differs from it by having aedeagus with processes and the three macrosetae instead of five macrosetae on lateral surface centrally.
