Gnezdilov, Vladimir M. & Bourgoin, Thierry, 2009, First record of the family Caliscelidae (Hemiptera: Fulgoroidea) from Madagascar, with description of new taxa from the Afrotropical Region and biogeographical notes, Zootaxa 2020, pp. 1-36 : 14-16

Genus Calampocus gen. n.

Type species: Calampocus sphaeroides sp. n.

Diagnosis (figs 26–28). Pedicel with rounded apical process. Brachypterous, venation obscure. Hind tibia with single lateral spine. First metatarsome nearly as long as second and third metatarsomeres combined, with single small intermediate and two lateral spines apically.

Male (fig. 26). Metope with surface with small concavities, without keels. Metoclypeal suture distinct only laterally. Coryphe, pronotum, and scutellum without keels, glossy. Fore wings reaching hind margin of second abdominal tergite.

Female (figs 27, 28). Metope with distinct sublateral keels and very weak median keel (from its middle to apex of proboscis). Lower part of metope and upper part of postclypeus forming a short proboscis. Coryphe transverse, with median keel, anterior and posterior margins almost straight. Pronotum short and wide, without keels, with very thin paradiscal fields, anterior margin convex, posterior margin straight. Scutellum twice as long as pronotum, with median keel.

Male genitalia (figs 75–81). Hind margin of pygofer straight. Anal tube nearly oval (in dorsal view). Anal column short and wide. Phallobase short and wide, narrowing apically—with nose-shaped apex (in lateral view) and with apical concavity (in ventral view). Phallobase with large process basally and pair of large lateral lobes covering ventral aedeagal hooks. The phallobase lobes bearing denticles. Aedeagal hooks long, acuminate, spirally curved. Right aedeagal hook running above basal process of the phallobase, but left hook running under the process. Style with convex margin under the capitulum, caudo-dorsal angle widely rounded. Capitulum of style long and narrow, without lateral tooth.

Female genitalia (figs 82–88). Chamber of ovipositor contained fragments of soil. Sternite VII with convex hind margin. Anal tube weakly narrowing apically. Anal column short. Gonoplacs short. First and second gonoplac lobes are separated by incision. Each distal part of posterior connective lamina of gonapophyses IX with longitudinal row of 10–11 teeth dorsally. Median field without lobes, with deep incision and with a median comb bearing setae. Lateral fields flat. Gonocoxa VIII with convex hind margin. Anterior connective lamina of gonapophysis VIII with only three large teeth in apical group.

Etymology. The genus name is derived from the Greek “καλαμπόκɩ”—corn, referring to rounded body shape. It is masculine in gender.

Comparison. The new genus is closely related to Afronaso Jacobi according to the structure of the phallobase with a large process and aedeagal hooks spirally curved (figs 75–77), but clearly distinguished by the sphaerical shape of the body and absence of metopial proboscis in male (fig. 26). The male of the new genus externally close to the genera Issopulex China & Fennah, 1960 and Savanopulex Dlabola, 1987 (figs 23–25), but differs in the structure of the phallobase mentioned above.
