Comments.
Alaptus nowickii
was described and well illustrated from a series of the female
holotype
,
9 female
paratypes
and
1 male
allotype
(deposited in RMCA, not examined) collected in
May 1938
by J. Ghesquière in the coffee plantations in Rutshuru, then
Belgian
Congo
(
Ghesquière 1939
). The examined non-type specimens from
the Democratic Republic of the
Congo
match its original description quite well. These slide-mounted females (
Fig. 190
), whose body length is 303–345 µm, are characterized by the following features: body, pedicel and flagellum of antenna brownish, scape and legs mostly yellowish; antenna (
Figs 191, 193
) with pedicel longer than any funicle segment (all funicle segments short but slightly longer than wide except sometimes F1 subquadrate), clava about as long as combined length of F2–F5 but sometimes of F1–F5, fore wing (
Fig. 192
) with 1–6 (but possibly as many as 8) setae in an incomplete median row (besides admarginal rows of microtrichia), about 9.2× as long as wide, and with its longest marginal seta about 4.8× maximum wing width; ovipositor 1.0–1.1× as long as metatibia, not exserted beyond apex of gaster. It is important to note that F2 of the male antenna of
A. nowickii
is a little longer than F1, as described and illustrated by
Ghesquière (1939)
, so it cannot possibly be conspecific with
A. iceryae
or its proposed synonym
A. priesneri
in which F2 of the male antenna is notably shorter than F1. The fore wing of
A. nowickii
is narrower than that of
A. andersoni
, which is 7.5× as long as wide in the
lectotype
, and the latter species also has a relatively shorter marginal setae on the fore wing (3.2× maximum wing width in the
lectotype
) and just 1 seta in the middle of the disc.
