Examined non-type specimens: 1 ♀; Portugal, Vila Real, Serra do Marão , 750 m, 21.05.1997; leg. W. Starke (cLB). – 1 ♂, 1 ♀; Portugal, Vila Real, Serra do Marão , 750 m, June 1997; leg. Th. Assmann (cLB). – 1 ♂; Portugal, Vila Real, Serra do Marão , 750 m, 10.06.1997; ( SDEI) .

Diagnosis: Size: 3.2-3.9 mm. Body colour auburn.

Pronotum: Underside at fore margin without rostral notch or channel, just somewhat sinuate. Metacoxae separated from mesocoxae by their diameter and about a quarter more; length of metasternum well as long as diameter of mesocoxae or as long as three of the coarse punctures in line; in middle of metacoxae on first ventrite coarsely punctuate with especially large, roundish-oval punctures ( Fig. 2B View Fig ), but not confluent in the shape of a groove.

Elytra L/W 1.57-1.62, elongate, parallel sided, widest behind middle ( Fig. 2C View Fig ). Striae coarsely and regularly punctuate, counting 14-16 punctures from elytral base to declivity.

Male genitalia: Penis rectangular, parallel sided, broadened, enlarged sidewards and margin sinuate at apex with small tip in the middle in dorsal-ventral view, in lateral view apex pointed, abruptly narrowed ( Figs 3 View Fig A- D). Female genitalia: ventrite VIII with plate inverted bell-shaped with forked branches thickened, apodeme as long as plate, apex inverted T-shaped ( Fig. 4A View Fig ). Spermatheca c-shaped, cornu attenuate towards rounded tip, base with globular ramus and hardly noticeable nodulus ( Fig. 4D View Fig ). Gonocoxite of ovipositor triangular, weakly sclerotized with parallel sided, tube shaped styli ( Fig. 4G View Fig ). Bursal atrium strongly sclerotized, frog bodyshaped in dorso-ventral view ( Fig. 4 View Fig L-M).

Derivation of name: The epithet “ spathiferum ” characterises the shape of the penis: “spatula” from Greek “σπΆΘΗ” and “fer” wearing.

Remarks: The specimens from the species’ population on Serra do Marão differ slightly from the typical ones from Serra da Estrela (see slightly narrower penis in Fig. 3 View Fig C-D), therefore they are not included in the type series. More specimens are needed to evaluate the significance of these differences.
