Oukhypencha florenceae sp. nov.

( Figs. 3 , 13, 17,29)

Specimens studied. Holotype by present designation: SW Java Palabuan-Ratu, Indonesia, Axel Preyer S. G. leg. ( ZMHB 1 ♂).

Diagnosis. Pygophore shape and rostrum length, reaching the mesocoxae, set this species apart from all others in the genus.

Description (male only, female unknown). Habitus: body of the common pentatomoid shape ( Fig. 3 ), general hue bronze brownish above, coria of a lighter brownish, underside yellow-brownish, apex of scutellum and forepart of each connexivum segment yellowish; punctation metallic green on head and fore part of scutellum.

Head. As in genus description; rostrum long, reaching mesocoxae. eyes and ocellae large (ocular index: 1.3; ocellar index: 1.7)

Thorax. Pronotum densely punctate, less so along posterior margin, callosities smooth, punctated in the middle: scutellum also densely punctate except apex. Corium overall densely and finely punctate; sternum punctate; evaporatoria small, reduced to narrow strips on both meso and metasternum; legs flavescent, apical black ring of posterior femora very thin, almost inconspicuous, length of apical teeth of posterior femora little more than half its diameter, tibiae furrowed outside, with black lines on either side of furrow.

Abdomen. Sternites sparsely and finely punctate; stigmates concolorous, trichobrothria just aft of median sternite scars, slightly closer to the middle than stigmates.

Male genitalia. Pygophore (Fig. 13) trapezoidal, posterior margin slightly convex, V-shaped, dorsally rimmed, rim connecting to an axial short ridge widening anteriorly, hypandrium short, triangular, broadly rounded at apex; phallotheca ( Fig. 17 ) fitted with three pairs of processus, one postero-ventral, biramose, lower part blade-shaped, strongly sclerotized, upper part membranous, one dorso-distal, membranous, third dorso-proximal, strongly sclerotized, lanceolate; phallobase weakly sclerotized; paramere ( Fig. 17 ) sinuous, sensorial lobe slightly protruding, fitted with a brush of setae about as long as paramere width, apophyse short and broadly rounded.

Measurements (mm): (holotype ♂) length 19,4; width 10.9; antennal articles length (A1: 0.9, A2: 3.5, A3: 4.0 (4 th antennomere missing)).

Host plant. Unknown.

Etymology. This species is dedicated to my friend Florence Missoffe.

Distribution. Indonesia (Java).

Discussion. This species differs by the organization of the genitalia. The first difference lies in the shape of the pygophore. It differs also from O. clemenceae by the number of processes of the phallus, from ophthalmica by the organization of the three processes of the conjunctiva. It has only one ventral processus but two dorsal ones, where ophthalmica has two ventral processes and only one dorsal.
