Michel, Bruno & Mansell, Mervyn W., 2010, Revision of the genus Ganguilus Navás (Neuroptera, Myrmeleontidae) with descriptions of three new species, Zootaxa 2386, pp. 1-24 : 19-21

Ganguilus indicus sp. n.

( Figs 41–48 )

Diagnosis

Medium sized. Yellow and black species. Wings hyaline with only black markings. Hind wings falcate ( Fig. 41 ). This species resembles G. pulchellus but can be distinguished from it by the coloration of the abdominal tergites and the clearly falcate hind wings.

Description

Size (mm). Forewing: 3 33; hind wing: 3 33: length of body: approx. 28.

Head. Face yellow with dark brown marking between antennal toruli. Frons dark brown. Vertex light brown with transverse brown marking. Scape, pedicel and flagellomeres brown. Terminal segment of labial palps slender slightly enlarged in proximal region.

Thorax. Pronotum yellow with two anterior and two dorso-longitudinal 7-shaped stripes extending from anterior groove to hind margin. Two lateral stripes extending from anterior groove to posterior margin ( Fig. 43 ). Mesoprescutum black with two lateral yellow dots; mesonotum yellow mainly black in anterior half; mesoscutellum yellow, black anteriorly. Metanotum yellow and black ( Fig. 44 ). Pleurites almost entirely dark brown.

Legs. Yellow. Spurs of fore- and middle tibiae as long as T1+2, of hind tibiae shorter than T1+2. Femoral brush of male with 29–30 setae.

Wings. Hyaline with black markings. In forewings RS arising a little beyond CuA fork. Five crossveins between R and MP before origin of RS. No black dot between R and MP before RS. Veins white; longitudinal veins with black striations. Hind wings clearly falcate with black stripe in apical area ( Fig. 41 ).

Abdomen. Tergite I black; tergite II black with anterior and posterior margins yellow; tergites III to VIII yellow with a dorsal brown marking indented at anterior 1/3. Sternite I black; sternites II black with an anterior lateral elongate yellow patch and hind margin bordered with yellow ( Fig. 45 ); following sternites almost entirely black. Male ectoprocts projected backwards with the angle formed by the basal part and the projection wider than in G. pulchellus ( Fig. 46 ). Parameres slender, evenly curved, pointed apically ( Figs 47 & 48 ).
