H o l o t y p e ♀: Myanmar: Hkamti, Sagaing Division, leg. local collector [cTM].

D e s c r i p t i o n: Measurements of the HT (in mm): BL: 4.8, FBL: 2.1, EL: 0.85, PL: 0.8, SL: 0.7.

Body blackish-brown, with distinct pubescence; legs and antennae orange-brownish, last segments infuscate.

Head with distinct elevated median portion of frons, distinctly exceeding the high of the inner eye margin (see arrow, Fig. 2 View Figs ). Labrum with long protruding silvery pubescence. Antennae slender (1.2 mm), club antennomeres IX–XI ( Fig. 3 View Figs ) longer than wide, length of antennomere IX: 0.07 mm; X: 0.05 mm; XI: 0.08 mm, ending in a small tip at the apex.

Pronotum densely punctated, largest punctures as large as basal cross-section of antennomere III; with small irregular depressions, longitudinal furrows not visible. Legs slender; tarsomeres with distinct pubescence, metatarsomere I as long as the combined length of metatarsomeres II–III, tarsomere IV very weakly bilobed.

Elytra broadest in posterior third, humeral angles prominent, posterior ends protruding beyond the posterior margin. Punctation widely, punctures about as large as those on pronotum, interstices larger than diameter of punctures. Coloration indistinctly discernible, possibly with one orange spot each in the posterior third ( Fig. 1 View Fig ).

Abdomen with very distinct pubescence; marginated, details of paratergites not clearly visible; row of u-shaped basal impression on tergite III.

Female. Sternite IX/valfivera apicolaterally acute ( Fig. 4 View Figs ).

D i f f e r e n t i a l d i a g n o s i s: The new species is distinguished from Festenus gracilis ŻYŁA et al., 2017 and Festenus robustus ŻYŁA et al., 2017 by its habitus, the size, the coloration of elytra and the cap-like elevation on the frons of the head.

E t y m o l o g y: The species epithet " annodutt " (German, colloquially: "anno dutt" from long ago) refers to the fact that the new species originates from the long ago time of the Late Cretaceous.
