Pseudodendrothrips marissae
sp.n.
Female macroptera
: In life, sharply bicoloured, abdomen almost white but head and thorax often with extensive red internal pigment. Body and legs largely pale; head extensively brown dorsally and ventrally but paler laterally; pronotum evenly light brown but paler on posterior third; antennal segments I and II as dark brown as head, III–IX light brown with III palest; fore wing basal third or quarter white (also clavus) in sharp contrast to dark median area that is gradually paler toward the apex (
Fig. 31
).

Pseudodendrothrips marissae
:
(29)
head and pronotum—paratype female in Hoyers Mountant;
(30)
head and pronotum—non-paratype female;
(31)
fore wing;
(32)
tergites IV–VI.
Structural details typical of genus; head weakly reticulate, ocellar setae III small arising just mesad of anterior margins of posterior ocelli (
Fig. 30
); compound eyes with about 7 weakly pigmented facets. Antennae 9- segmented, sense cones on III and IV elongate and U-shaped; VI with sense cone arising close to base, VII clearly distinct from VI. Pronotum transversely reticulate, reticles with internal markings; posterior margin with 3 (sometimes 4) pairs of setae of which outer 2 pairs longest. Mesonotal setae small, metanotum typical of genus (
Fig. 30
). Fore wing with 7 veinal setae, clavus with 2 veinal and one discal setae; costal cilia arising almost at anterior margin; posteromarginal cilia straight.
Hind
tarsi very long, about 0.8 as long as hind tibiae. Tergites II–VIII lateral thirds with transverse rows of small longitudinal ridges (
Fig. 32
), median setal pair long and close together; VIII with long marginal comb; IX and X with band of discal microtrichia on posterior third. Sternites transversely reticulate, III–VII with 3 pairs of marginal setae, II with 2 pairs, setae on VII arising sub-marginally.

Comments
. The dark fore wing with the basal fifth sharply pale distinguishes this species from its congeners in
Australia
. Moreover, the pronotum is more evenly brown in colour, rather than bearing discrete brown areas (
Fig 29
). The females excluded from the
type
series have the pronotum rather paler (
Fig. 30
), the fore wing more extensively pale distally, and the males with the body and wings almost uniformly pale. In common with all the
Pseudodendrothrips
known from
Australia
, the apex of the hind tibia in
marissae
bears a single stout seta, in contrast to the two such setae found in
aegyptiacus
, a pale bodied species that is widespread from eastern Mediterranean countries, including
Egypt
,
Israel
and Abu Dhabi, to southern Africa and the Canary Islands.
