Figure 1 . Lateral view of the designated lectotype of Alloxysta fulviceps (Curtis). 
stated that the mesoscutum is completely black. For these reasons, 
we must consider that the specimen that was chosen as lectotype 
does not fit the original description by Curtis. On the other hand, 
we have examined the one remaining specimen of Curtis’s type 
series, which corresponds exactly with Curtis’s description. In 
summary, we designate here a new lectotype for Alloxysta 
fulviceps (= Cynips fulviceps Curtis), which has the following 
labels: ‘ Alloxysta minutal (Hrt.) 9 det. Quinlan 1986’ (white 
label), ‘this specimen has not type-status’ (white label), ‘MUS. 
VIC. ENTO 2011-4-L’ (green label), ‘this specimen has type 
status JP-V, 2011’, ‘27 Cynips fulviceps bred from Aphides female 
by Aphidius? T.C. 13 July 26 — [unreadable] Dorset. Bred from 
aphids of Willows and Cow Parsnip Hal’ (photocopy of Curtis 
original annotations of his notebook), ‘lectotype of Cynips 
fulviceps Curtis, 1838 9 , designed J.P-V 2011’ (red label), 
‘Alloxysta victrix (Westwood, 1833) Ferrer-Suay det-2011 (white 
label). 
Our study of this material also shows that A. fulviceps is 
the same species as A. victrix. Therefore, in this study, the 
synonymy of A. fulviceps and A. erythrothorax is removed, a 
new lectotype for A. fulviceps is established, this species is 
synonymised with A. victrix and the validity of A. erythrothorax 
(Hartig) is re-established. 
The taxonomic changes we propose restructure the list of 
synonyms and valid species implied, so we present it here: 
Alloxysta erythrothorax (Hartig, 1840) Dalla Torre and 
Kieffer, 1902 
Xystus erythrothorax (Hartig, 1840, p. 200). Synonymised by 
Quinlan and Fergusson (1981, p. 254). Type: ZSBS (according to 
Evenhuis, 1982, p. 23). 
Xystus defectus (Hartig, 1841, p. 352). Synonymised by Fergusson 
(1986, p. 10). Type: ZSBS (according to Evenhuis, 1982, p. 22). 
Allotria nigriventris (Thomson, 1862, p. 409). Synonymised by 
Fergusson (1986, p. 10). Type: MZLU (according to Andrews, 1978, p. 
87). 
Comments : Hellen (1963) redescribed A. erythrothorax and A. 
defecta. The latter was synonymised with the former by 
Fergusson (1986). The two species match chromatically. 
Fergusson (1986) also synonymised A. nigriventris (Thomson)
