description: <i>Notocoderus argentinus</i> Henry &amp; Dellapé, sp. n. urn:lsid:zoobank.org:act: A758B508-3C7F-42D4-8CDD-E5FC37560877 Figs 1–4, 7–12 <b>Diagnosis</b>. Th is species is best recognized by the small size, the strongly convex anterior pronotal lobe (Figs 1, 4), the narrow and shorter posterior lobe with a distinct tubercle at each humeral angle (Figs 2, 3), and the dull brown hemelytron (Fig. 1), with a white mark on the basal third and apex of the corium. <b>Description</b>. Holotype male (Figs 1–4): Head, pronotum, scutellum, clavus, corium, pleura, sterna, abdomen, rostrum, antennae, and legs pale brown to brown. Antennal segments III and IV, and apex of II and rostral segment IV darker brown. Corium with a white subbasal macula and a narrow white band along posterior margin bordering membrane, whitish areas impunctate. Membrane fuscous with a narrow translucent margin. Head, pronotum, and scutellum coarsely punctate. Head, pronotum, scutellum and narrowly explanate lateral margin of hemelytron and apex of corium shiny; remainder of corium and clavus dull. Antenna with short semierect setae, more abundant distally; segment I robust, segment IV fusiform. Anterior pronotal lobe globose, transverse impression separating lobe deep. Dorsum with numerous erect, pale setae, shorter and less abundant on hemelytra. Abdomen cylindrical. Total length 2.50 mm, width across hemelytra 0.80 mm. Head length 0.40 mm, head width 0.61 mm, interocular space 0.42 mm. Labium extending to mesosternum, but not quite reaching mesocoxae; total length about 0.90 mm, length of segment I 0.19 mm, II 0.24 mm, III 0.24 mm, IV 0.18 mm. Antenna: Length of segments I 0.19 mm, II 0.35 mm, III 0.27 mm, and IV 0.42 mm. Pronotum: Length of anterior lobe 0.50 mm, length of posterior lobe 0.19 mm; anterior pronotal lobe 2.58 times longer than posterior pronotal lobe; width of anterior lobe 0.61 mm, width of transverse impression 0.45 mm, and width of posterior lobe 0.54 mm. Scutellum slightly longer than wide, depressed across middle, lacking a median carina. Membrane sclerotized, <b>Figures Ι–6.

Hemelytron length to apex of membrane 1.58 mm, length to apex of corium 0.99 mm. Paratype female (slide mounted, Figs 7–12): Head, pronotum, and scutellum densely and deeply punctate; clavus and corium more sparsely punctate, except for im- punctate white basal third and apex of corium. Hind wings apparently absent. Sterna II to IV fused; sterna V and VI with a pale sutural line medially. Laterotergites III and IV fused, suture lost. Terga membranous, tergite VI partially sclerotized medially; dorsal abdominal scent gland scar openings distinct between terga IV/V and V/VI. Female: Head length 0.61 mm, width 0.72 mm, interocular space 0.48 mm. Labium: Length 1.01 mm, segment I 0.21 mm, II, 0.29 mm, III 0.22 mm, IV 0.29 mm. Antenna: Segment I length 0.18 mm, II 0.38 mm, III 0.26 mm, IV missing. Pronotum: Length 0.80 mm, width of anterior lobe 0.74 mm, width of transverse impression 0.46 mm, width of posterior lobe 0.50 mm; length of anterior lobe 0.56 mm, length of posterior lobe 0.24 mm. Hemelytron: Length to apex of corium 1.04 mm, length to apex of membrane 1.81 mm, width 0.50 mm (1.00 mm across hemelytra). <b>Etymology</b>. The specific epithet <i>argentinus</i> is used to denote the country origin of this interesting new species. <b>Discussion</b>. Th is species is distinct among the Oxycarenidae based on the shape of the bilobed pronotum (Figs 1, 4), with a well-developed tubercle at each posterolateral angle (Fig. 3), and the subbrachypterous hemelytra with four white maculae (Fig. 1), one on the basal third and apex of each corium. The holotype and paratype were taken in pitfall traps set in two southern hilly areas of Buenos Aires Province, Sistema Serrano de Tandilia and Sistema Serrano de Ventania, respectively. <b>Type material</b> . <b>Holotype.
