Hadronema incognitum View in CoL , sp. nov. Figures 2, 29, 32, 34, 36

DIAGNOSIS: Recognized by the relatively large size (table 1); the metathoracic scentgland evaporatory area strongly reduced; the genital capsule subquadrangular (fig. 29), with the ventral right prolongation long (fig. 29, arrow); the insertion of left paramere on genital capsule nearly ventral; the left paramere weakly sinuate, gently curved before the apex (fig. 29, arrow); and females with subgenital plate long, broadly truncate apically (fig. 34), almost reaching posterior margin of eighth sternum.

Hadronema incognitum is distinguished from other species of Hadronema , except H. militare , by the subquadrangular genital capsule, relative large size, and weakly sinuate left paramere. Hadronema incognitum is similar to H. militare in coloration, size, and structure, but can be easily separated from it by the rather gently curved left paramere at the apex (fig. 29), and by not having the rami clubbed (fig. 29, arrow). Hadronema incognitum is also slightly smaller than H. militare (table 1).

DESCRIPTION: Male: Large, total length 3.73–4.17. COLORATION: Black with red and whitish markings (fig. 2). HEAD: Black, clypeus with two lateral and one basal longitudinal irregular shiny black marking; frons with two longitudinal areas of irregular oblique shiny black lines; two shiny black areas in front of ocular ridge next to eyes; suture between mandibular and maxillary plates shiny black, apex of mandibular plate reddish black; labrum black, shiny; labium black, segments III–IV shiny black; antennae pitch black. THORAX: Pronotum and collar black, anterior margin sometimes reddish black; calli black with scattered irregular shiny areas; posterior lobe mostly black, fading to red posteriorly, posterior margin whitish; mesoscutum reddish black, laterally more strongly red; scutellum black, sometimes apically pale; proepisternum black; proepimeron with anterior half black, sometimes reddish black, posterior half reddish orange, ventroposterior margin pale; mesepisternum and mesepimeron black; metepisternum black, weakly reddish black on center; venter black. Hemelytra: Clavus black; corium mostly black, costal margin and adjacent area white; cuneus white on lateral half; area between corium and membrane shiny black; membrane fuscous, veins dark brown. Legs: Black. ABDOMEN: Black, membrane of dorsal margin of sternites orange, posterior margin weakly pale. GENI- TALIA: Genital capsule black; proctiger bright orange, ventrally and apically brown; left paramere brownish black, apically brown; right paramere brown. STRUCTURE: THO- RAX: Metepisternum with evaporatory area reduced and peritreme greatly enlarged. Legs: Profemur with large basal ventral process, bifid. GENITALIA (fig. 29): Genital capsule subquadrangular, apparently cleft in ventral view, left side posteriorly rounded and beset with numerous long setae forming a sensory lobe, right side with a long posteriad prolongation; supragenital bridge heavily sclerotized; left paramere insertion almost ventral, nearly straight, weakly sinuate, gently curved before apex, with two apical small processes apically, one directed ven- trad; right paramere with a small acute process apically; rami of ventral spicule of subequal length, anterior one shorter, posterior one barely longer, both rami approximately of same width, not clubbed at the apex; dorsal spicule denticulate on apical third, about a third the length of ventral spicule.

Female: Similar in coloration and structure to male (fig. 2), but larger and more strongly oval, total length 4.36–5.01. STRUCTURE: GENITALIA: Subgenital plate subrectangular, long, almost reaching posterior margin of sternite VIII, apex broadly truncate (fig. 34); dorsal lobes of interramal sclerites narrow, of medium size (fig. 32); central sclerotized area on posterior wall heavily sclerotized, trapezoidal, not divided transversely, medial posteriorly directed tubercle prominent, bearing numerous small tubercles, dorsal margin of sclerotized area with small denticles (fig. 34); sclerotized rings as in figure 32.

DISTRIBUTION: Hadronema incognitum is restricted to California and Oregon, ranging from the Cascades and Sierra Nevada west to the Coast Range (fig. 36).

HOSTS: Hadronema incognitum has been found mostly associated with Lupinus adsurgens , several unidentified species of Lupinus (Fabaceae) , and Senecio sp. (Asteraceae) . A few specimens were found on Vicia sp. (Fabaceae) . Two specimens associated with Phacelia hastata (Hydrophyllaceae) may be sitting records. Some specimens (e.g., AMNH_PBI 00102745) were also found on Lupinus plants with Meloidae . This is consistent with reports of associations with Meloidae for other species of Hadronema ( Pinto, 1978; Young, 1984a, 1984b).

ETYMOLOGY: The species is named from the Latin adjective ‘‘incognitus’’, meaning not known, and refers to the fact that this new species was unnoticed in collections under ‘‘ H. militare ’’.

DISCUSSION: Hadronema incognitum has been confused in collections with H. militare . It not only shares with H. militare a similar coloration, relative large size, and male genitalic structures, but also similar hostplant associations. Nevertheless, characters on the genital capsule and left paramere (see above) support its status as a new species.

Hadronema incognitum and H. militare do not overlap in their range, although they are both present in Modoc County, California. It is not known if they concur in other peripheral areas of their distributional range. Hadronema militare is widely distributed, whereas H. incognitum is restricted to California and Oregon. This restricted western distribution is similar to what is found for instance in Slaterocoris solidaginis Kelton ( Kelton, 1968) View in CoL , Squamocoris fumosus Stonedahl and Schuh ( Stonedahl and Schuh, 1986) View in CoL , Lopidea marginata Uhler ( Asquith, 1991) View in CoL ( Miridae View in CoL : Orthotylinae ), and several species of Oligotylus ( Schuh, 2000a) View in CoL ( Miridae View in CoL : Phylinae ). Disjunct distributional patterns between sister groups, like H. incognitum and H. militare , are common in Miridae View in CoL , as in the case of Ceratopsallus View in CoL and Bisulcopsallus ( Schuh, 2006) View in CoL .
