Key to males of Mexican and Central American species of Mortoniella  

1 Dorsal phallic spine with prominent saddle-like lateral extensions; apex widened, upturned and recurved ( Fig. 17A, D View FIGURE 17 ) ................................................................................................. M. pacuara (Flint)  

- Dorsal phallic spine without saddle-like lateral extensions.....................................................................2

2(1) Segment IX with spine-like ventral process ( Fig. 26A View FIGURE 26 )..................................... M. rodmani   , new species

- Segment IX without spine-like ventral process.......................................................................................3

3(2) Inferior appendage with distinct apicomesal projection ( Figs. 1C View FIGURE 1 , 12C View FIGURE 12 )................................................4

- Inferior appendage without apicomesal projection ( Fig. 8C View FIGURE 8 ), or with apicomesal projection very short, much shorter than apicolateral projections ( Fig. 5C View FIGURE 5 ).............................................................................13

4(3) Lateral margins of inferior appendage with elongate dorsolateral branches ( Fig. 1A, C View FIGURE 1 ); apicomesal projection of inferior appendage broad, rounded apically, symmetrically tapered ( Fig. 1C View FIGURE 1 ) ( Costa Rica)..................................................................................................................................................................5

- Lateral margins of inferior appendage without elongate dorsolateral branches; apicomesal projection of inferior appendage narrow, acute or subacute apically, usually asymmetrically curved ( Figs. 12C View FIGURE 12 , 13C View FIGURE 13 )..................................................................................................................................................................7

5(4) Dorsolateral branches of inferior appendage bifid apically, with elongate setae laterally ( Fig. 32A, E View FIGURE 32 ); apicomesal projection of inferior appendage short ( Fig. 32C View FIGURE 32 ) ............................. M. tapanti   , new species

- Dorsolateral branch of inferior appendage not bifid apically ( Fig. 1A View FIGURE 1 ), with elongate setae or not; apicomesal projection of inferior appendage more elongate ( Fig. 1C View FIGURE 1 ).........................................................6

6(5) Dorsolateral branches of inferior appendage only slightly broadened, with no or only a few scattered setae ( Fig. 4A, C View FIGURE 4 ) ........................................................................................... M. anakantha   , new species

- Dorsolateral branches of inferior appendage distinctly broadened preapically, forming basket-like processes, each with brush of elongate setae on interior and exterior surfaces ( Fig. 1A, C View FIGURE 1 ) .......................... ............................................................................................................................ M. akantha   , new species

7(4) Apicomesal projection of inferior appendage very elongate, apex distinctly scabrous ( Fig. 13A, C View FIGURE 13 ); phallicata without dorsolateral processes and endophallic membrane without unpaired apical spine .. 8 1

- Apicomesal projection of inferior appendage not scabrous, relatively short ( Fig. 12C View FIGURE 12 ) to distinctly elongate ( Fig. 31C View FIGURE 31 ); phallicata and endophallic membrane variable.......................................................9

8(7) Paramere appendage elongate, extending beyond dorsal phallic spine; apicomesal projection of inferior appendage more linearly projecting, apex less distinctly enlarged ( Fig. 13A View FIGURE 13 ) ....... M. meralda (Mosely)  

- Paramere appendage short and narrow, much shorter than dorsal phallic spine; apicomesal projection of inferior appendage more sinuous, apex distinctly, bulbously enlarged ( Fig. 20A View FIGURE 20 )................................ ...................................................................................................................... M. panamensis   , new species

9(7) Paramere appendage relatively broad, with scattered short, thick spines on apical half ( Fig. 7A, C View FIGURE 7 ); ventral spine of endophallic membrane present, prominent, curved ( Fig. 7A View FIGURE 7 ) .... M. buenoi   , new species

- Paramere appendage without spines; ventral spine of endophallic membrane present only in M. leroda   , in which it is short and straight ( Fig. 12A View FIGURE 12 )............................................................................................10

10(9) Apicomesal projection of inferior appendage relatively short (sometimes lightly sclerotized and difficult to see) ( Figs. 12A, C View FIGURE 12 ; 14A, C View FIGURE 14 ) ( Mexico).........................................................................................11

- Apicomesal projection of inferior appendage more elongate and distinctly sclerotized ( Figs. 9A, C View FIGURE 9 ; 31A, C View FIGURE 31 ) ( Costa Rica)..............................................................................................................................12
