Treatment

Jocezia inusitata Dellapé & Fuentes , new species

( Figs. 1 View FIGURE 1 , 2 View FIGURE 2 )

Holotype. Male. ARGENTINA, Corrientes, Berón de Astrada , 11-VII-2017, Fuentes-Rodríguez D. col. ( MLP).

Etymology: The epithet is derived from the Latin word “inusitata”, meaning rare, unusual, or uncommon, referring to the peculiarities of its morphology and also the infrequency with which this stink bug has been collected.

Description. Small size (body length 7mm, abdominal width 3.5mm). Coloration predominantly castaneous with dark brown to black punctures. Lateral margins of mandibular plates dorsal and ventrally black. Antennae reddish. Pronotum densely and uniformly punctate, with darker areas along lateral margins ( Figs. 1A, 1D View FIGURE 1 ). Mandibular plates longer than clypeus, not contiguous before clypeus ( Fig. 1D View FIGURE 1 ). First labiomere occupying approximately two thirds of bucculae and covered by them in lateral view. Pronotum trapezoidal, anterior two thirds slightly declivent; anterolateral angles with a small tooth. Connexivum covered by the forewings in the rest position, with dark brown to black punctures. Ventral surface of abdomen uniformly punctate, but more densely punctate along spiracles ( Figs. 1B–C View FIGURE 1 ).

Male genitalic structures: dorsal rim of pygophore (dr) excavated in an open “U” shape; posterolateral angles rounded and slightly projected posteriorly. Superior layer of ventral rim (sl) expanded in 1+1 conical projections (cp), anteriorly projected, without teeth, reaching almost the transversal carina, on each side of proctiger. Inferior layer of ventral rim (il) carinate, with 1+1 small –barely visible– tooth-like projections (tp) separated from each other; carina evanescent between the tooth-like projections. Surface of ventral rim, between layers, irregularly concave and scarcely punctate. Ventral surface of pygophore punctate in posterior half ( Figs. 2A–C View FIGURE 2 ). Proctiger (x) wider than longer, with a transversal carina (cx) in basal third, surface of distal two-thirds concave and punctate; apex rounded and slightly expanded ( Figs. 2D–E View FIGURE 2 ). Phallus almost as long as wide, dorso-ventrally flattened. Articulatory apparatus (aa) with simple basal plates; dorsal connectives (dc) and processus capitati (pca) well-developed. Phallotheca (ph) broadly opened posteriorly; ventral face with 1+1 broad, subparallel median processes widened at apex, processus phallothecae 1 (pph1), shorter than pcj1; and dorsal face with 1+1 small blunt lateral processes, processus phallothecae 2 (pph2), near articulation zone with basal plates. Posterolateral angles of phallotheca rounded and slightly developed. Processus conjunctivae 1 (pcj1), in 1+1 digitiform thin arms, with apical third dorsally curved; and processus conjunctivae 2 (pcj2), in 1+1 stout structures, with acute apex dorsally curved; a small finger-shape tumescence (tu) dorsally to base of processus conjunctivae 2. Vesica (v) with a dorsal shield-like process, processus vesicae (pv) smoothly grooved transversally ( Figs. 2F–K View FIGURE 2 ). Ductus seminis distalis (dsd) helicoidal and sclerotized in distal portion ( Fig. 2L View FIGURE 2 ).

Female unknown.

Distribution. Argentina: Corrientes.

Host plant. Poaceae : Oryza sativa L. “rice”.

Comments. The specimen was collected in a commercial rice field during winter (rice stubble). Several species currently placed in Carpocorini are known to be pests of Poaceae , particularly rice, e.g. many species of Oebalus Stål , Mormidea Amyot & Serville , and Tibraca Stål ( Panizzi et al. 2000). In South America, species of Glyphepomis Berg and Hypatropis are associated with rice crops, but its status as pest is unknown ( Farias et al. 2012; Krinski et al. 2015).
