MNHN.F.C02458 (A. Nel leg., one specimen, a nearly complete female with apex of one wing missing and gas bubbles on wing bases, in same piece of amber with a Ceratopogonidae, a Chironomidae, and a fragment of apical part of a rather large wing of an Odonata: Zygoptera), stored in Muséum national d’Histoire naturelle (MNHN), Paris, France. Images and specimen accessible under request to curator of collection.</p><p>Horizon and locality. Lowermost Eocene (Ypresian), Le Quesnoy outcrop near Creil (Houdancourt village), in Oise Department, Hauts-de-France, France.</p><p>Diagnosis. Female characters only, unique combination of characters not found in described taxa of Hellichiella . 10 antennomeres; palpomere IV distinctly shorter than palpomeres II and III together; pedisulcus visible but shallow; calcipala rather large and apically pointed; vein Rs ending in C very far basal to terminus of C; basal radial cell short.</p><p>Description. Body 1.9 mm long; head 0.3 mm long, 0.8 mm wide; eyes 0.36 mm wide, without line of discontinuity between large upper facets and small lower facets; eyes not in contact at centerline above antenna, 0.08 mm apart; 10 antennomeres; pedicel larger than first flagellomere; both maxillary palps visible; palpomere IV distinctly shorter than palpomeres II and III together; palpomere V elongate; sensory vesicle occupying about slightly less than one fourth of palpomere III; thorax 0.9 mm long, 0.6 mm wide; scutum unpatterned; precoxal bridge complete; wing hyaline, 1.8 mm long, 0.92 mm wide; C with hair-like macrotrichia interspaced with thicker spiniform macrotrichia; Sc with short setae; short basal radial cell, representing 28% of distance from base of Rs to wing apex, basal section of R with spiniform setae dorsally; R1 ending on C distal middle of wing; Rs nearly appressed to R1, not distally forked, ending in C very far basal to terminus of C, and with short setae dorsally and ventrally; CuA distinctly sinuate; absence vs presence of basal medial cell cannot be determined because of presence of gas bubbles at bases of both wings; both hind legs visible; hind basitarsus with a distinct calcipala and second tarsomere with shallow pedisulcus; all claws each with a broad basal thumblike lobe; abdomen 0.92 mm long, 0.7 mm wide; structures of female genitalia hardly determinable, but apparently genital fork with lateral plates broadly joined to corresponding tergite.</p><p>Etymology. Named after the Oise department.</p></div>	https://treatment.plazi.org/id/93650F65FFCD512FFF3E32182EA3FEC8	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.
