Paralygocoris balicus , new species

( Figs. 12 H−J, 16, 33)

Type material. Holotype: male, INDONESIA: Bali, Tabanan, Candikuning , 8°17′S 115°10′E, local collector, 8–12 March 1996 ( ZRC) ( AMNH _ PBI 00378788 ) . Paratypes: INDONESIA: 3 males, 5 females, same data as for holotype ( AMNH, TYCN) .

Diagnosis. This new species can be distinguished from other congeners by the characters mentioned in the above key, in addition to the identical male and female genitalic structures, such as short, rather bulbous right paramere with small, blunt-tipped hypophysis ( Fig. 16C ); slender, elongate vesical spicule recurved apically ( Figs. 16D , 33I–L ); elongate-ovoid sclerotised rings contiguous to each other mesally ( Figs. 16F , 33K ); and triangular dorsal structure ( Fig. 33N ).

Description. Body yellowish or stramineous brown, elongate oval, subparallel-sided; dorsum shining, impunctate, with uniformly distributed, brown, simple setae. Head shiny pale brown, with a pair of brown, symmetrical, C-shaped maculae in front; apices of clypeus and buccula infuscate. Antenna dark brown; female antennomere II with pale basal ⅓ and obscure subbasal ring ( Fig. 12J ); extreme base of antennomere III creamy yellow. Labium yellowish brown, reaching middle of mesocoxa; apical half of segment IV darkened. Thoracic pleura pale brown; mesal stripe on scutellum not reaching apex; metathoracic scent efferent system as in Fig. 33C . Hemelytron shiny pale brown; inner half of clavus fuscous; corium with a pair of dark spots apically; membrane pale smoky brown. All coxae and legs yellowish brown; metafemur with two brown apical rings subapically; each tarsomere III darkened. Abdomen pale brown. Male genitalia ( Fig. 16A–E , 33G–J ): Sensory lobe of left paramere weakly produced apically ( Figs. 16A, B , 33H ); right paramere rather bulbous, with small, blunt-tipped hypophysis ( Fig. 16C ). Vesica with elongate spicule recurved apically ( Figs. 16D , 33I–L ). Female genitalia ( Fig. 16F–H , 33K–O ): sclerotised rings elongate-ovoid, contiguous to each other mesally ( Figs. 16F , 33K ); posterior wall with and small interramal lobes ( Figs. 16E , 33N ); dorsal structure triangular, densely covered with spinules ( Fig. 33O ).
