1♀
, same data as holotype
.
Comparative diagnosis.
Belongs to the group of
Cratospila
species together with
C. alboapicalis
Tobias, 1990, described from
Vietnam
in having the apical half of
♀
antenna with 8-13 white segments. However, in
C. alboapicalis
length of eye 4-5 times length of temple in dorsal view (1.9 times in the
C. albifera
sp. nov.) and antenna of
♀
with dark apical segments (only white segments in
C. albifera
sp. nov.). Differs from the very similar
C. luteocephala
sp. nov. by having the minimum width of face 1.2 times its height (0.9 times in
C. luteocephala
sp. nov.), vein r of fore wing ca 5 times longer than wide (ca 3 times), and first subdiscal cell of fore wing ca 5.0 times longer than wide (ca 7.5 times). COI sequence of
C. albifera
sp. nov. differs by 10% from that of
C. luteocephala
sp. nov. (Table
1
).

3.1 mm
; Antenna 1.2-1.4 times longer than body in female, 27-32-segmented. First flagellomere 1.9-2.0 times longer than second; metasoma 2.7-2.8 times longer than apical width; setose part of ovipositor sheath 0.58-0.61 times as long as mesosoma, 0.46-0.51 times as long as hind tibia and with long setae.

Etymology.
Named after the white apex of the
♀
antenna: "
Cratospila albifera
" is derived from
"albus"
(Latin for white) and
"fero"
(Latin for carry or bear).
