Key to species-groups of Mesembrinella

1 Anterior thoracic spiracle with a broad oval opening above ( Fig. 5 View FIGURES 1–8 ); discal scutellar setae usually present (as in Fig. 194 View FIGURES 193–194 ); disc of T5 with or without a row of discal setae ( Fig. 8 View FIGURES 1–8 shows T5 with row of discal setae) (not to be confused with discal setae on the scutellum); most species with 3x 3 postpronotal setae...................................................... 2

- Anterior thoracic spiracle with a long, narrow opening gradually widening above ( Fig. 6 View FIGURES 1–8 ); discal scutellar setae absent; disc of T5 without row of stout setae; with 2x 2 postpronotal setae........... M. bolivar group [four species; formerly Giovanella ]

2 Male with epandrium large and elongate, broadly divided dorsally over its full length (as in Figs 104 View FIGURES 103–104 , 491 View FIGURES 489–497 ), with surstyli and cerci tiny and at posterior end ( Figs 27, 29 View FIGURES 27–32 ); sternites much wider than long (ST4 about 4x wider than long), posterior edge of ST5 with pair of posteriorly-pointed projections midway [ Fig 12 View FIGURES 9–14 (see arrow), Figs. 245–246 View FIGURES 239–251 ]; sternites shorter and partially hidden in M. mexicana sp. nov. ( Fig. 245 View FIGURES 239–251 ) [for lone females, terminalia should be dissected and examined; two species, M. mexicana sp. nov. and M. spicata , are similar ( Figs 289–290 View FIGURES 288–293 ), the other, M. guaramacalensis sp. nov., is as in Fig. 288 View FIGURES 288–293 ]............................................................. M. spicata group [three species; formerly Henriquella ]

- Male with epandrium smaller, surstyli and cerci more typical, as in Figs 35–98 View FIGURES 33–38 View FIGURES 39–40 View FIGURES 41–46 View FIGURES 47–52 View FIGURES 53–56 View FIGURES 57–62 View FIGURES 63–68 View FIGURES 69–74 View FIGURES 75–80 View FIGURES 81–86 View FIGURES 87–92 View FIGURES 93–98 , except M. anomala ( Figs 99–100 View FIGURES 99–102 ); sternites much narrower, often longer than wide, ST1–4 never more than 2x wider than long ( Figs 247–279 View FIGURES 239–251 View FIGURES 252–265 View FIGURES 266–279 ); posterior edge of ST5 without projections.................................................................................... 3

3 Disc of T5 with horizontal row of stout setae ( Fig. 8 View FIGURES 1–8 ), rest of T5 with fine setulae. Male: surstylus usually more or less straight, parallel-sided; cercus curved anteriorly (as in Fig. 39 View FIGURES 39–40 ); phallus usually significantly narrowed just anterior to hypophallic lobe (as in Fig. 130 View FIGURES 125–134 )...................................... M. aeneiventris group [13 species; formerly Huascaromusca ]

- Disc of T5 without horizontal row of stout setae midway, with short- to medium-length fine setae and setulae over whole surface, dense in most species but sparser in a few species; surstylus and cercus usually curving toward each other in lateral view (as in Fig. 63 View FIGURES 63–68 ); phallus usually not significantly narrowed anterior to hypophallic lobe ( Fig. 148 View FIGURES 145–152 )...................... 4

4 Stem vein setose ( Fig. 489 View FIGURES 489–497 ); wing with dark infuscation along costa from subcosta-costa junction to R 2+3 -costa junction, including all of r 1 cell; section IV of wing 0.30 (0.27–0.33/5) of section III; male frons broad, 0.20 of head width at narrowest; cerci in posterior view right-angled midway ( Fig. 26 View FIGURES 21–26 ); female terminalia as in Fig. 287 View FIGURES 282–287 ; [known only from Brazil]..................................................................... M. latifrons group [1 species; formerly Albuquerquea ].

- Stem vein usually bare; if setose, then other combination of characters different.................................... 5

5 Male: T5 1.5– 2x as long as T4 (as in Fig. 496 View FIGURES 489–497 ); terminalia very unusual, with surstylus short and broad and cercus small and slender ( Figs 99–100 View FIGURES 99–102 ). Female T6 of FU shape with broad division midway ( M. anomala , Fig. 324 View FIGURES 324–325 ; condition unknown in M. andina )................................................. M. anomala group [2 species; formerly Thompsoniella ]

- Male: T4 and T5 of equal length; terminalia unlike those in Figs 99–100 View FIGURES 99–102 . Female T6 without a broad division (except in M. decrepita )................................................................... M. bicolor group [22 species].
