Metacephalus DeLong & Martinson 

( Figures 1–3View FIGURE 1View FIGURE 2View FIGURE 3)

Metacephalus DeLong & Martinson 1973: 225  , Figs. 1View FIGURE 1 –6. Type species: M. albocrux DeLong & Martinson, 1973  . Paraportanus Carvalho & Cavichioli 2009: 26  , Figs. 1View FIGURE 1 –14. Type species: P. jenniferae Carvalho & Cavichioli, 2009  . (syn. nov.)

Diagnosis. (partly based on Carvalho & Cavichioli 2009 and Carvalho 2012 for Paraportanus  ): Crown ( Figs. 1View FIGURE 1, 4, 11, 14, 21, 24) with anterior margin rounded. Crown, pronotum, and/or mesonotum ( Figs. 1View FIGURE 1, 11, 21) usually marked with vibrant orange markings. Male pygofer (Figs. 5, 15, 25) strongly produced usually bearing pair of distinct spiniform processes on posteroventral margin. Subgenital plates (Figs. 6, 16, 26) triangular narrowing to apex; without unpigmented transverse line at basal third. Connective (Figs. 7, 17, 27) V- or Y-shaped with very short stalk.

Remarks. Carvalho & Cavichioli (2009) noted that species of Paraportanus  could be divided into two groups; however, characters given for the separation of these groups are ambiguous for M. albocrux  . Metacephalus albocrux  shares with M. jenniferae  ( Paraportanus  type species) the broad and bifid style apex (Fig. 7); but with members of the other group, the fused connective and aedeagus (articulated in M. jenniferae  ).
