Key to Mexican ’ nassa ’ species complex of Amphibolips

1. Mesoscutellum rounded posteriorly ( Figs 37–38 )................................................ ’ niger’ complex in Mexico [galls rounded, with very dense furry surface ( Fig. 46 )], and all known Amphibolips species from USA and Panama

- Mesoscutellum with posteromedian emargination ( Figs 10 , 32 , 39–40 )........................................... 2

2. Posterior sides of mesoscutellum, aside of posteromedian impression, strongly emarginate, dorsally V-shaped, with sharp horn projection in lateral view ( Figs 40–41 )...................................................... palmeri and dampfi

- Posterior part of mesoscutum more or less impressed but dorsally not V-shaped, without sharp horn projection in lateral view ( Figs 10 , 32 , 39 )................................................................................. 3

3. Heavy dark stripe along anterior margin of forewing interrupted by clear unpigmented cross band in cell delimited by R1+Sc and Rs+M ( Fig. 34 )............................................................................. 4

- Heavy dark stripe along anterior margin of forewing uninterrupted in cell delimited by R1+Sc and Rs+M ( Fig. 14 )........ 5

4. F3 1.3 times as long as F4; gall elongate, spindle-shaped, with hard and lignified parenchima ( Figs 42–43 ), on Q.castanea (= Q. serrulata ) and Q. mexicana ....................................................................... nassa

- F3 equal in length to F4 ( Fig. 5 ); gall rounded, with soft and spongious parenchima ( Figs 18–20 ), on Q. crassifolia , Q. cras- sipes and Q. candicans .................................................................. hidalgoensis n. sp.

5. Head quadrangular in front view, anterior tentorial pits small, distance between them 7.0 times as large as diameter of pit ( Fig. 1 ); scutellar foveae as long as broad ( Fig. 9 ); forewing with short dense cilia on margin; metasoma black; gall rounded, only slightly elongate to apex, with soft and spongious parenchima ( Figs 15–17 ), on Q. eduardi ............ zacatecaensis n. sp.

- Head rounded in front view, anterior tentorial pits large, distance between them only 3.0–3.5 times as large as diameter of pit ( Fig. 47 ); scutellar foveae longer than broad ( Fig. 48 ); forewing without cilia on margin; metasoma dark brown; gall elongate, spindle-shaped, with hard parenchima ( Figs 44–45 ), on Q. eduardi .......................................... fusus
