Description

Crown has anterior region yellow, while posterior area is yellow-milky, wider than pronotum. Face yellow, relatively long, with anteclypeus yellow (Fig. 2 C). 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. 2 A and B). Male abdominal apodemes extended not beyond hind margin of 3rd sternite (Fig. 4 H).

Diagnosis

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

Etymology

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

Taxon discussion

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 Typhlocyba 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.
