Diagnosis

Recognized by the following characters: total body length 3.2–3.7; corium uniformly yellow, without dark pattern ( Fig. 3D ); antenna uniformly dark brown, usually with reddish tinge; right lateral wall of genital capsule deeply excavated, with large, apically rounded sclerotized outgrowth ( Fig. 21A–B ); right paramere flattened, with broadly semicircular dorsal expansion ( Fig. 21C–D ); base of aedeagus with large, characteristic, uniformly sclerotized outgrowth; apex of aedeagus with small, entirely membranous lobe ( Fig 21F ).

Etymology

Named after the type locality, Castle Rock, a village in the Western Ghats Mts, Karnataka.

Description

Male

COLORATION. Dorsum pale lemon yellow to pale brown ( Fig. 3D–E ); head pale yellow, antennal segments dark brown to reddish brown; pronotum yellow, sometimes with pale brown anterior angles; pro-, meso- and metathorax laterally brown, ventrally pale brown or yellow; scutellum pale brown to dark brown; hemelytron uniformly lemon yellow, with narrowly brown or black costal margin and claval commissure; legs uniformly yellow; abdomen yellow ventrally, pale brown at sides.

STRUCTURE. Total length 3.2–3.5; body 3.5–3.7× as long as basal width of pronotum; head transverse, vertex 1.8–2.0× as wide as dorsal width of one eye, 0.8–0.9× as wide as length of antennal segment I; segment II 0.8–0.9× as long as head width, 0.6× as long as basal width of pronotum; pronotum 1.8–1.9× as wide as long.

GENITALIA. Genital capsule ( Fig. 21A–B ) subquadrate, short and broad, about 1.5× as wide as long, with large aperture; right lateral wall of capsule deeply excavated, with prominent, apically rounded process. Left paramere ( Fig. 21E ) scythe-shaped, with slightly and uniformly swollen body and gradually tapering, apically upturned apical process. Right paramere ( Fig. 21C–D ) somewhat larger than left one, broad, lamellate, with strongly expanded, semicircular body. Aedeagus ( Fig. 21F ) tubular, C-shaped, very thin and evenly sclerotized, with small, entirely membranous apical lobe; Dorsal wall of aedeagus at base with large, hook-shaped sclerotized outgrowth, apically flattened and serrated.

Female

Unknown.

Host

Unknown. All specimens were attracted to light.

Distribution

Southwestern India, Karnataka state.

Remarks

The new species is easily distinguished from N. sirsiensis gen. et sp. nov. by its more uniform dorsal coloration and striking features of the male genitalia. A peculiar sclerotized outgrowth originating from the extreme base of the aedeagus seems to be a unique feature within eccritotarsines.
