Description: Head round, eyebridge of 3 facet rows; distance between eyes 4 facet diameters; laterally of eyes a single row of postocular bristles. Palpus segments, absolute length: 0.066-0.088- 0.096-0.164 mm; relative length: 33-44-48-82. Antenna with scape, pedicel and 14 flagellomeres: absolute length 0.052 -0.042 -0.04-0.042-0.046- 0.044-0.044-0.046-0.044-0.04-0.038-0.036-0.034-0.022- 0.018-0.024 mm; relative length: 26-21-20-21-23-22-22- 23-22-20- 19-18-17-11 - 9-12 mm; terminal flagellomere with a short apiculus; pairs of digitate ascoids on flagellomeres 5–11.

Wing 2.67 times longer than wide, length 1.83 mm, width 0.68 mm.

Male terminalia with hypandrium broadened over 1/3 of its length with parallel sides ( Fig. 8View FIGURES 8–14). Gonocoxites approximately 2x longer than wide slightly bent, on basal edge 2 short ‘fingers’ jointed to the hypandrium; inner side with basal broadening with a group of longer setae, in the basal third with a single seta longer than gonocoxite; gonostylus almost straight, as long as gonocoxite.

Parameres with a broad ventral bridge, in the midst develops a racket-shaped ‘plate’, part of the aedeagus sheath; above a pair of thin inner processes that do not meet in the middle; further dorsal large condyles developed that converge in the middle with strongly sclerotized parallel sides that develop a ‘keel’ that underpins the basiphallus sclerite.

Basiphallus with ventral arm bilobed, shorter lobe connected to the distiphallus, longer lobe slightly bent medially thickened with blunt tip; distiphallus a specifically shaped cross sclerite, both ends with sharp tips, another tip on the broad end folded ventral. The dorsal lobe of the basiphallus distally as broad as the distiphallus ( Fig. 9View FIGURES 8–14), which is in dorsal view roughly triangular with abundantly folded margin.

Epandrium rhomboid, epandrial processes straight, apically with 10–12 feathered tenacula.

Distribution: Great Britain, Central and South-West Europe.

Remarks: Tonnoiriella pulchra  was originally placed in genus Pericoma  , a type locality was not given ( Eaton 1893). However, in the British Museum (Natural History) one specimen is labelled as holotype (must be lectotype!) selected by A.L. Tonnoir. The lectotype and additional specimens from Eaton’s bequest give an adequate impression of the species. Specimens from different areas in Europe vary slightly in size but the morphology of the terminalia is remarkably constant. Summarizing the knowledge on Psychodidae  in North Africa Afzan & Belqat (2016) mentioned T. pulchra  from Morocco and Algeria, based on literature references; it is most probable that their original references included misidentifications of related species, probably T. paveli Ježek 1999  .
