Key to the species of the Ambrysus pulchellus View in CoL species complex
1. Female subgenital plate (SGP) triangular, posterior margin tapered to a rounded apex ( Fig. 6F View FIGURE 6 ), lateral margins reflexed dorsally; posterior margin of laterosternite VI almost straight ( Fig. 6F View FIGURE 6 ). Male accessory genitalic process (AGP) capitate, widest apically ( Fig. 6B View FIGURE 6 ); pseudoparameres straight mesally, with low and inconspicuous rounded apical lobe ( Fig. 6C View FIGURE 6 ). Both sexes with scutellum with two reniform to ovate dark brown marks ( Fig. 6A View FIGURE 6 )..................... Ambrysus vanduzeii Usinger
1'. Female SGP not triangular, posterior margin broad ( Figs. 3F View FIGURE 3 , 4F View FIGURE 4 ) or with central concavity ( Fig. 1F View FIGURE 1 ), lateral margins not reflexed; posterior margin of laterosternite VI almost straight ( Figs. 1F View FIGURE 1 , 4F View FIGURE 4 ) or strongly convex ( Fig. 3F View FIGURE 3 ). Male AGP wider in distal half, but tapering apically ( Fig. 1B View FIGURE 1 ) or widest preapically ( Fig. 4B View FIGURE 4 ), or widest in basal 2/3 ( Fig. 3B View FIGURE 3 ); pseudoparameres with medial convexity ( Figs. 1C View FIGURE 1 , 3C View FIGURE 3 , 4C View FIGURE 4 ), tapering to a pointed ( Fig. 1C View FIGURE 1 ) or narrowly rounded apical lobe ( Fig. 4C View FIGURE 4 ), or without apical lobe ( Fig. 3C View FIGURE 3 ). Both sexes with scutellum almost uniformly light brown ( Fig. 1A View FIGURE 1 ), or uniformly colored ( Fig. 4A View FIGURE 4 ), or with dendritic pattern ( Fig. 3A View FIGURE 3 )........................................................................... 2
2. Female SGP with deep concavity on posterior margin, posterolateral corners slender and posteriorly produced ( Fig. 1F View FIGURE 1 ). Male AGP uniformly wider in distal half and tapering apically ( Fig. 1B View FIGURE 1 ); pseudoparameres tapering to a pointed apical lobe ( Fig. 1C View FIGURE 1 ). Scutellum usually almost uniformly light brown or a heterogeneous pattern of brown tones ( Fig. 1A View FIGURE 1 )...................................................................................................... A. buenoi Usinger View in CoL
2'. Female SGP without deep concavity on posterior margin, posterolateral corners only slightly produced posteriorly ( Figs. 3F View FIGURE 3 , 4F View FIGURE 4 ). Male AGP widest in basal 2/3 ( Fig. 3B View FIGURE 3 ) or widest preapically ( Fig. 4B View FIGURE 4 ); pseudoparameres tapering to a narrowly rounded apical lobe ( Fig. 4C View FIGURE 4 ) or without an apical lobe ( Fig. 3C View FIGURE 3 ). Scutellum almost uniformly dark brown ( Fig. 4A View FIGURE 4 ) or with dark brown dendritic pattern ( Fig. 3A View FIGURE 3 )............................................................................... 3
3. Scutellum almost uniformly dark brown ( Fig. 4A View FIGURE 4 ). Pronotum surface glabrous, body glossy. Female SGP posterior margin rounded and with inconspicuous posterolateral corners ( Fig. 4F View FIGURE 4 ); posterior margin of laterosternite VI straight ( Fig. 4F View FIGURE 4 ). Male AGP widest preapically ( Fig. 4B View FIGURE 4 ); pseudoparameres tapering to a narrowly rounded apical lobe ( Fig. 4C View FIGURE 4 ).................................................................................................. A. pulchellus Montandon View in CoL
3'. Scutellum with dark brown dendritic pattern on medium brown background ( Fig. 3A View FIGURE 3 ). Pronotum surface finely irregular, body not unusually glossy. Female SGP posterior margin with four conspicuous lobes ( Fig. 3F View FIGURE 3 ); posterior margin of laterosternite VI convex ( Fig. 3F View FIGURE 3 ). Male AGP widest in basal 2/3 ( Fig. 3B View FIGURE 3 ); pseudoparameres without apparent apical lobe, posteromesal corners rounded ( Fig. 3C View FIGURE 3 )............................................................
