Hodgson, Chris, 2012, Comparison of the morphology of the adult males of the rhizoecine, phenacoccine and pseudococcine mealybugs (Hemiptera: Sternorrhyncha: Coccoidea), with the recognition of the family Rhizoecidae Williams 3291, Zootaxa 3291 (1), pp. 1-79 : 60

Key to the known adult males of Neochavesia species :

1. Antennae 5 segmented; claw longer than width of tarsus....................................................... 2

- Antennae 2 segmented; claw shorter than width of tarsus.................................. N.? trinidadensis ( Fig. 21 )

2. Caudal extensions on abdominal segment VIII subequal in length to penial sheath; claws all long and narrow; setae on head and thorax distinctly shorter than those on abdomen; constriction of abdomen slight, narrowing gradually to segment III....................................................................................... N. caldasiae ( Fig. 19 )

- Caudal extensions on abdominal segment VIII clearly shorter than penial sheath; claws all long and blade-like; setae on head and thorax similar to those on abdomen; constriction of abdomen very pronounced, abruptly narrowing to segment III........................................................................................... N. lapollai ( Fig. 20 )
