(Figs 6–8)
Female. Body fully extended; pronotum basally slightly dented; basal abdominal segments difficult to assess due to shiny refraction; legs folded under body except right mid leg; fore wings overlapping hind wings.
Colour (Fig. 6) uniformly light brown including antennae and legs; all major setae and wing fringes dark; wing veins coloured pale greyish-brown, only a shade darker as wing membrane.
Head (Fig. 6) with reticulate sculpture particularly in the middle; about as long as wide and produced in front of anterior margin of eyes, with cheeks slightly rounded behind eyes; cheeks lacking setae; one pair of long but very fine ocellar setae close to base of antennae. Eyes not prolonged ventrally. Hind ocelli close to compound eyes; far apart from each other. Vertex with postocular setae far behind eyes (left seta missing). Antennae 9-segmented; segment I barrel-shaped; segment II basally asymmetric without elongated pedicle; III–VIII symmetrical, inverse conically shaped and tapering distally from level of sense cones; sensorium on segment II not visible; number of sense cones of the following segments difficult to assess but at least one inner and one outer on III–VI and one outer only on VII; segment IX conically shaped, at base narrower than segment VIII distally. Mouth cone short and rounded. Maxillary palps 2-segmented; labial palps minute, not assessable. Pronotum wider than long, trapezoidal; posteroangular setae long and pointed, other pronotal setae not developed or missing; epimeral setae long and pointed. Metanotum with a pair of fine setae far apart from the front margin of the plate. Prosternum with fernal plates wider than long; basantra not visible (very likely not developed); mesopresternum complete, very flat boatshaped; mesosternellum and metasternum fused. Fore wings (Fig. 6) becoming progressively larger in distal half; anterior vein complete, reaching costa near apex; bearing two distal setae and one basal seta located anteriorly to the vein; straight except for the short bending close to its tip; second vein not developed; membrane without microtrichia. Fringe cilia straight; arising from sockets; duplicated cilia present around apical margin of wing; clavus with paired setiform processes at tip. Hind wings at base clearly with microtrichia (Fig. 8); without any veins; base with recurved setae; sockets of wing fringes smaller as on fore wing (Fig. 7). Fore legs with femora stout; fore tarsi with two teeth. Mid and hind legs slender. All femora with one long ventral and all tibiae with one long dorsal seta; mid and hind tibiae terminally each with three spines, much smaller on mid tibiae; mid and hind tarsi two-segmented, with hamus. Abdominal tergites faintly sculptured reticulate (partly visible only), without wing-retaining setae; lateral setae long, pointed; setae s3 on IV–VII longer than other lateral setae and conspicuously bent inwards (Fig. 6). Abdominal segment I (pelta) not assessable; IX conical, with setae s3 long and somewhat protruding tube; sternite IX with structures interpretable as gynosternal plates and fustis (cf. Bhatti 1998b). Abdominal segment X (tube) conically extended at base; its sculpture not assessable; apparently without campaniform sensilla; with terminal crown of long anal setae.

Sense cones, length of inner (outer) on segment III 20 (18), IV 22 (19), V 22 (25), VI 25 (19), VII – (16); basal width 4–5. Fore wings, length 1030; largest width 206.
Syninclusions. Remnants of another insect and a stellate trichome.
Etymology. The species R. patrickmuelleri is dedicated to Patrick Müller for his generous donations of Burmese amber thrips inclusions.
