TYPE MATERIAL. — Holotype adult (probably ♂) ( MNHN, AR 92.1 About MNHN ) and paratype adult ( MNHN, AR 92.2 About MNHN ) originally in single piece of turbid amber from Archingeay-Les Nouillers , Charente-Maritime , France : Lower Cretaceous, uppermost Albian, lithological subunit A1 sensu Néraudeau & Moreau (1989).
ETYMOLOGY. — The species is named after Marie-Noëlle and Jean-Marc Rossi.
DESCRIPTION OF HOLOTYPE
Carapace ( Fig. 2A View FIG ) with small, regular and dense granules, eyes large (maximum diameter 0.061 mm). Chelicera ( Fig. 2C View FIG ) with five setae on palm, b and sb shorter than others, but without obvious denticulation, es long; seta of movable finger subapical, extending past tip of spinneret; spinneret with about three or four, non-terminal, rudimentary rami; palm and movable finger reticulate. Coxae ( Fig. 2B View FIG ) normal; setae small and sparse. Palps ( Fig. 3 View FIG A-C, E) moderately granulate; fixed finger with small, sparse granules extending for about half length of finger on paraxial side. Setae short, apart from a patch of longer setae ventrally just after pedicel ( Fig. 3C View FIG ). Femur graduallypedicellate; palm ovate, but not as robust as Figure 3A View FIG suggests (foreshortened due to oblique view). Trichobothriotaxy as illustrated ( Fig. 3E View FIG ); ib situated in a shallow furrow; it near middle of finger, slightly distad of est; st slightly nearer to t than to sb. Spot sensilla not clearly visible, but a lighter spot between trichobothria st and t might represent coupled sensilla pc (i.e. p 1 + p 2) ( Fig. 3E View FIG ). Teeth large, contiguous, cusped (not triangular) and upright. Trochanters of legs with one ventral seta longer than others. Leg I with tarsus of normal shape ( Fig. 3F View FIG ), but distal setae longer (longest 0.15 mm) and more numerous than on other tarsi. Claws of leg I largely obscured, but anterior (paraxial) claw seems to be simple; claws of other legs simple. Legs III and IV ( Fig. 3G View FIG ) with a long (c. 0.30 mm on IV) tactile seta near base (TS IV index 0.19); subterminal setae simple, curved. Arolia shorter than claws and fan-shaped.
Measurements of holotype Carapace c. 0.82×?0.53(c. 1.6).Palp trochanter0.37 × 0.2 (1.7), femur c. 0.82 × 0.20 (4.0), patella? × 0.24, chela + 0.92 × <0.33 (> 2.8), chela – 0.89 (> 2.7), palm + 0.49 (> 1.5), palm – 0.46 (> 1.4), movable finger 0.49 (1.0 × palm +). Leg I tarsus 0.33 × 0.07 (4.7). Leg III tibia 0.49 × 0.14, tarsus 0.38 × 0.079.
DESCRIPTION OF PARATYPE
The few parts of the palp and posterior legs that can be observed clearly are very similar to those of the holotype. The only additional information provided by this specimen concerns the form of the palp patella ( Fig. 3D View FIG ), which is better preserved than that of the holotype.
Measurements of paratype
Palp femur 0.78 × 0.20 (4.0), patella c. 0.69 × 0.25 (c. 2.8), palm + c. 0.54 × 0.30 (c. 1.8), palm – c. 0.49 (c. 1.7).
REMARKS
The holotype lies close to an incomplete specimen of a heteropteran, but the association between the two is probably fortuitous.
