Key for New World species of Argopistes

1. Body rounded in dorsal view and strongly convex in lateral view, almost hemispherical ( Figs 20, 21 ); aedeagus strongly arched in lateral view ( Fig. 23 ); spermathecal receptacle elongate, nearly parallel-sided ( Fig. 24 ).................. A. rubicundus

– Body oblong oval in dorsal view and convex in lateral view (Figs 1–3); aedeagus straight or nearly straight in lateral view ( Figs 5 , 14 , 32 , 46 ); spermathecal receptacle ovoid, with outer side straight and inner side convex ( Figs 7 , 17 , 33 , 47 )..... 2

2(1). Bare, basal part of first metatarsomere about as long as apical part covered with setae...................... A. turnbowi

– Bare, basal part of first metatarsomere longer than apical part covered with setae................................... 3

3(2). Aedeagus with short laminae covering dorsal opening, not projecting beyond apical part of aedeagus ( Fig. 32 )... A. scyrtoides

– Aedeagus with long laminae covering dorsal opening, projecting beyond apical part of aedeagus ( Figs 6 , 14–16 , 46 )...... 4

4(3). Tip of aedeagus bent dorsally in lateral view ( Fig. 46 ), vaginal palpus more or less triangular in shape with median side much shorter than lateral ( Fig. 48 ).................................................................... A. woodleyi

– Tip of aedeagus bent ventrally in lateral view ( Figs 46 ), vaginal palpus more or less trapezoidal in shape ( Fig. 8 ) [if more or less triangular, posterior margin strongly sinusoidal ( Fig. 18 )].................................................. 5

5(4). Two apical antennomeres darker than rest of antenna; legs dark brown to reddish brown; posterior margin of vaginal palpus slightly sinusoidal ( Fig. 8 ); spermathecal pump abruptly narrowing apically, evenly curved towards receptacle ( Fig. 7 ); aedeagus slender, with apical part only slightly wider than middle in ventral view ( Fig. 5 )................... A. coccinelloides

– Two apical antennomeres as light as rest of antenna; legs yellowish; posterior margin of vaginal palpus strongly sinusoidal ( Fig. 18 ); spermathecal pump gradually narrowing apically, sinusoidal ( Fig. 17 ); aedeagus robust, with apical part significantly wider than middle in ventral view ( Figs 14–16 ).................................................... A. coronatus
