CRYPTOCEPHALINA

PRONOTUM: Denticles present ( Figs. 15 View FIGURES 9 – 15 , 19 View FIGURES 16 – 20 , 23 View FIGURES 21 – 26 ) or absent on basal margin ( Figs. 33 View FIGURES 31 – 37 , 42 View FIGURES 40 – 45 ); basal margin convex and mesally truncate over mesoscutellum ( Figs. 9 View FIGURES 9 – 15 , 19 View FIGURES 16 – 20 , 23 View FIGURES 21 – 26 , 33 View FIGURES 31 – 37 , 42 View FIGURES 40 – 45 ); pronotal punctures absent or distinct throughout, strongly pronounced on all margins.

HYPOMERON: Hypomeron projection cylindrical ( Fig. 13 View FIGURES 9 – 15 ); hypomeron without distinct punctures ( Figs. 9, 12 View FIGURES 9 – 15 ). PROSTERNUM: Intercoxal prosternal process truncate, bimodal or acutely bimodal; intercoxal prosternal process with caudal M­shaped rim ( Figs. 13 View FIGURES 9 – 15 , 20 View FIGURES 16 – 20 ); prosternal opening open, when viewd caudally; posterior margin of intercoxal prosternal process concave, never projecting beyond hypomeron ( Fig. 9 View FIGURES 9 – 15 ); anterior margin of prosternum uniformly concave or with medial flange; intercoxal width equal to, greater than, or less than width of coxal cavity.

Cryptocephalus: Denticles present on basal margin of pronotum ( Figs. 15 View FIGURES 9 – 15 , 19 View FIGURES 16 – 20 ); pronotal punctures distinct throughout ( Figs. 10, 12 View FIGURES 9 – 15 ). Intercoxal prosternal process acutely bimodal ( Figs. 13 View FIGURES 9 – 15 , 20 View FIGURES 16 – 20 ); anterior margin of prosternum uniformly concave or with medial flange; intercoxal width equal to or greater than width of coxal cavity ( Figs. 9 View FIGURES 9 – 15 , 19 View FIGURES 16 – 20 ).

Bassareus: Denticles present on basal margin of pronotum ( Fig. 23 View FIGURES 21 – 26 ); pronotal punctures distinct throughout ( Figs. 23, 24 View FIGURES 21 – 26 ). Intercoxal prosternal process bimodal (in males intercoxal prosternal process with medial projection) ( Fig. 23 View FIGURES 21 – 26 ); anterior margin of prosternum with medial flange (in males with sublateral indentations and lateral projections) ( Fig. 21 View FIGURES 21 – 26 ); intercoxal width equal to width of coxal cavity; without pronounced ridge bordering coxal cavity ending as small lateral projections on intercoxal prosternal process.

Triachus: Denticles absent on basal margin of pronotum ( Figs. 40, 42 View FIGURES 40 – 45 ); pronotal punctures absent ( Fig. 43 View FIGURES 40 – 45 ). Intercoxal prosternal process truncate ( Fig. 40 View FIGURES 40 – 45 ). Anterior margin of prosternum uniformly concave ( Fig. 40 View FIGURES 40 – 45 ); intercoxal width less than width of coxal cavity.

Diachus: Denticles absent on basal margin of pronotum ( Figs. 31, 33 View FIGURES 31 – 37 ); pronotal punctures absent ( Fig. 34 View FIGURES 31 – 37 ). Intercoxal prosternal process truncate. Anterior margin of prosternum uniformly concave; intercoxal width less than width of coxal cavity ( Fig. 31 View FIGURES 31 – 37 ).
