Makarkin, Vladimir N., Perkovsky, Evgeny E. & Gröhn, Carsten, 2019, Neotype designation and re-description of Prolachlanius resinatus (Hagen) (Neuroptera, Hemerobiidae) from Baltic amber, with the first record of the species from Rovno amber, Zootaxa 4688 (1), pp. 57-70 : 59

Genus Prolachlanius Krüger, 1923

Type species. Hemerobius resinatus Hagen in Pictet-Baraban et Hagen, 1856 , by original designation.

Diagnosis. May be easily distinguished from other genera of the subfamily by male genitalia (e.g., elongated ectoprocts with strong setae and spines apically; extremely short 8th sternite), and distal branch of RP being not deeply forked and presence of crossveins 4r-m in the forewing.

Species composition. The type species, known from Baltic and Rovno ambers, and probably one undescribed species from Baltic amber.

Remarks. One specimen deposited in the private collection of Thomas Weiterschan probably represents a new species of the genus. It differs from Prolachlanius resinatus by forewing characters, e.g., the widely-spaced subcostal veinlets, the one-branched CuA, and its narrower, paler wing almost lacking maculation.
