( Figs. 3, 4 View FIGURES 1 – 8 , 13, 14 View FIGURES 9 – 16 , 22–26 View FIGURES 22 – 26 , Table 1 View TABLE 1 )

Diagnosis. Recognized by yellow coloration of the body dorsally and ventrally; endosoma very broad, heavily sclerotized with saw-like projections on inner and outer margins along with spine-like spicules medially and phallotheca with crenulations on dorsal surface apically.

Description. Male. Elongate, ovoid, with lateral corial margins concave; total length 2.58–2.62, width pronotum 1.30–1.41. COLORATION ( Fig. 3 View FIGURES 1 – 8 ): Body dorsally and ventrally pale yellow; eyes reddish brown, membrane, corium at the junction of the claval suture and cuneus fuscous; lorum reddish, antennal segments I, II and III reddish brown, last segment dark brown; metathorasic scent gland evaporatory area pale white; legs fore, mid and hind femur with distinct red markings and row of black spots medially. SURFACE AND VESTITURE: Shining with sparse yellow lanceolate sericeous scale-like setae and recumbent reclinate black setae; thoracic pleura and abdomen ventrally with silvery scale-like setae; fore and mid coxa with spine-like black recumbent setae. STRUCTURE: Head: With posterior margin including eyes concave, eyes not protuberant; antennae distinctly separated from margins of eyes, arising at or below the ventral margins of eyes in lateral view; eyes occupying half the head height laterally. Pronotum: Lateral margins straight with a single erect spine-like setae anteriorly humeral angles sharply rounded, posterior margin nearly straight; mesoscutum exposed, separated from scutellum by a weak suture; scent gland evaporatory area prominent. Hemelytra: Lateral margins straight, broader than abdomen, cuneus with prominent cuneal incisure. Legs: Hind femur swollen moderate. GENITALIA ( Figs. 22–26 View FIGURES 22 – 26 ): Pygophore: Transverse, tapering and rounded distally. Endosoma: Broad, curved at base, apex flattened paddle-shaped, heavily sclerotized with few serrations on inner and outer margins and spine-like spicules on the tube, 1/4th from base; secondary gonopore with semicircular opening, subtended by long, glassy spicules. Phallotheca: Elongate, curved apically on the ventral margin, dorsal margin with crenulations. Left paramere: Not splayed out, anterior processes short, small finger-like, posterior processes apex weakly curved. Right paramere: Broad, flattened and tapering towards apex.

Female. Fitting the description of the male; total length 2.59–2.75, width pronotum 1.35–1.37.

Distribution. Know from a single locality Karnataka, Nandi Hills.

Host. Breeds on Viscum articulatum ( Fig.13, 14 View FIGURES 9 – 16 )

Etymology. The species name is derived of, and is the host plant name.

Discussion. Hypseloecus articulatum on the basis of male genitalic character appears close to H. paramyemi Schuh & Menard but differs by presence of serrations on inner and outer margins and spine-like spicules on the tube basally on the endosoma, secondary gonophores visible with semicircular opening and presence of crenulations on phallotheca, whereas in H. paramyemi endosoma is smooth and secondary gonophore is invisible and phallotheca is not crenulated. Externally H. articulatum is distinguished by pale yellow coloration.
