n. sp.
(
Fig. 2
)
Shape and colour of scale covering of the adult female unknown, since all specimens of the type-series were scale-less.
Male not observed.
Adult female
; as in generic diagnosis, but body circular-oval;
0.5–1.3 mm
long,
0.4–0.6 mm
wide. Pygidium with poorly-defined 4 pairs of lobes; median lobes narrowly separated from each other, together forming a broad triangular projection; second lobes triangular; third lobes smaller than the second; fourth lobes triangular. Segmental setae on pygidial margin each 16–30 μm long. Without pygidial marginal scleroses. Without perivulvar pores. Dorsum of abdominal segments VIII, VII and VI with a reticulated pattern of dark and bright areas which are disposed perpendicularly to pygidial margin. Anal opening oval, about 14 μm long, 7 μm wide; separated from pygidial apex at a distance about 7 times its longer axis. Vulva placed at a level about twice that of anal opening. Anterior and posterior spiracles without perispiracular pores. Antennal tubercle situated submarginally, with one hair. Microducts, of 1-barred
type
, each about 25 μm long, 1 μm in diameter; on venter disposed submarginally from pygidium up to level with posterior spiracle, plus a few anterior to both spiracles; a few also disposed near pygidial margin on dorsum. Dorsal intersegmental line between segments IV and III present as a discontinued, dark, sclerotised line.
Etymology
. The species epithet refers to the reticulated pattern on the pygidial dorsum of the adult female.
Type
material
. All specimens were collected in
Madagascar
by B.L. Fisher, from galleries of
Melissotarsus insularis
Santschi
, on various host plants.
