03E69D0BC65B4F74FF02F94AFD13044A.taxon	discussion	The first species of this family, Ectoedemia occultella, was described in 1767 (Linnaeus 1767). From then on, discoveries and descriptions of Nepticulidae occurred unevenly across 23 time periods (i. e., decades) from 1767 until 2021 (Fig. 34). After the first species was published, the discovery of new species proceeded very slowly until 1840, but then starting in 1841 and continuing until 1890, the number of new pygmy moths soared. However, 1881 – 1900 marked a recession, and then in 1901, a general tendency for an increase in the number of discoveries of new species was observed with slight fluctuations. Two periods clearly stand out: 1971 – 1980 and especially 2011 – 2021, during which the largest numbers of new species were discovered and described. Understandably, the total, accumulative number of new species of Nepticulidae increased with each time period, but it was particularly apparent during 1971 – 1980 when the curve of the total number of species rose steeply. During the 255 years of research, 1,000 species were discovered, about 3.92 average species per year. But there is great difference in the average of species described per year between the early 20 th and early 21 st centuries.	en	Dobrynina, Viktorija, Stonis, Jonas R., Diškus, Arūnas, Solis, M.

03E69D0BC6554F7BFF02FF61FDDA07C5.taxon	discussion	The earliest species of the Opostegidae was Pseudopostega auritella, published in 1813, although not yet named as the family Opostegidae at that time (Hübner 1796 – 1838) (Fig. 35). The analyzed data shows that discoveries of new Opostegidae species were extremely few until the 19 th century: a maximum of four described species per time period or decade, or no species described at all. A surge in the number of descriptions was observed at the beginning of the 20 th century. In the years 1911 – 1920 was the highest peak of discovery, when 35 new Opostegidae species were described. From 1931, a sharp decline was observed, which lasted until 1980: only three new species were described during this time period. The total or accumulative number of Opostegidae species gradually increased, and in 1981 – 1990 there was gradual increase in numbers every decade. The year 1981 opened up significant increase in the number of new species described. In 2001 – 2010 a record-breaking number of the Opostegidae species were described (74 new species) (Davis & Stonis 2007; Remeikis et al. 2009). But from 2011, there was a decline once again, when only seven new species were described until 2021. A total of 197 Opostegidae species were published during 209 years of research; an average annual number of species descriptions is 0.94 a year. However, these averages significantly differ in the 19 th century (0.22 species per year), the 20 th century (0.97 species per year), and the 21 st century (3.86 species per year).	en	Dobrynina, Viktorija, Stonis, Jonas R., Diškus, Arūnas, Solis, M.

03E69D0BC6554F7BFF02FCE9FE660005.taxon	discussion	The first species of the family, Tischeria ekebladella, was described in 1795 (Bjerkander 1795) (Fig. 36). Analysis of the data showed that, starting in 1795 until 1870, the discovery and description of new species proceeded slowly, only a total of 10 new species were described at this early stage of research. During 1871 – 1880, 15 new species were described, and during 1911 – 1920, 10 new species. Many new species of Tischeriidae were discovered and published during 1971 – 1980 (19 species) and 2021 – 2010 (27 species). The boost in the number of species discoveries occurred in 2011 – 2021, when 62 new Tischeriidae species were described. The total, accumulative number of described species rose gradually, but it should be noted that the extremely rapid rise occurred at beginning of the 21 st century. A total of 170 Tischeriidae species were described during the 227 years of research, the average number of descriptions per year is 0.75 species. In the 18 th century, the actual annual average was 0.17 species; in the 19 th century it was 0.28 species; in the 20 th century it was 0.52 species; and in the 21 st century it was 4.24 species. It is clear that the annual average was increasing with each century, but a particular increase occurred early in the 21 st century (Fig. 36).	en	Dobrynina, Viktorija, Stonis, Jonas R., Diškus, Arūnas, Solis, M.
