description: 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) ................................................................................................. M. pacuara (Flint)   
- Dorsal phallic spine without saddle-like lateral extensions.....................................................................2  
 2(1) Segment IX with spine-like ventral process (Fig. 26A)..................................... M. rodmani, new species   
- Segment IX without spine-like ventral process.......................................................................................3  
3(2) Inferior appendage with distinct apicomesal projection (Figs. 1C, 12C)................................................4  
- Inferior appendage without apicomesal projection (Fig. 8C), or with apicomesal projection very short, much shorter than apicolateral projections (Fig. 5C).............................................................................13  
4(3) Lateral margins of inferior appendage with elongate dorsolateral branches (Fig. 1A, C); apicomesal projection of inferior appendage broad, rounded apically, symmetrically tapered (Fig. 1C) (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, 13C)..................................................................................................................................................................7  
 5(4) Dorsolateral branches of inferior appendage bifid apically, with elongate setae laterally (Fig. 32A, E); apicomesal projection of inferior appendage short (Fig. 32C) ............................. M. tapanti, new species   
- Dorsolateral branch of inferior appendage not bifid apically (Fig. 1A), with elongate setae or not; apicomesal projection of inferior appendage more elongate (Fig. 1C).........................................................6  
 6(5) Dorsolateral branches of inferior appendage only slightly broadened, with no or only a few scattered setae (Fig. 4A, C) ........................................................................................... 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).......................... ............................................................................................................................ M. akantha, new species   
 7(4) Apicomesal projection of inferior appendage very elongate, apex distinctly scabrous (Fig. 13A, C); phallicata without dorsolateral processes and endophallic membrane without unpaired apical spine.. 8 1   
- Apicomesal projection of inferior appendage not scabrous, relatively short (Fig. 12C) to distinctly elongate (Fig. 31C); 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) ....... 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)................................ ...................................................................................................................... M. panamensis, new species   
 9(7) Paramere appendage relatively broad, with scattered short, thick spines on apical half (Fig. 7A, C); ventral spine of endophallic membrane present, prominent, curved (Fig. 7A) .... 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)............................................................................................10   
10(9) Apicomesal projection of inferior appendage relatively short (sometimes lightly sclerotized and difficult to see) (Figs. 12A, C; 14A, C) (Mexico).........................................................................................11  
- Apicomesal projection of inferior appendage more elongate and distinctly sclerotized (Figs. 9A, C; 31A, C) (Costa Rica)..............................................................................................................................12  
11(10) Tergum X with lateral lobes elongate, mesal margin deeply incised (Fig. 14B); apicomesal projection
