03E387941573FF91FCF4FA10FE622873.taxon	discussion	Comments: Diclidophlebia venosa fits the concept of Diclidophlebia redefined by BURCKHARDT et al. (2023) by the pterostigma of the forewing, which is leathery in the proximal half and membranous in the distal half (a synapomorphy of the genus), and the presence of well-sclerotised apical spurs on the metatibia arranged in two groups. Another diagnostic character of Diclidophlebia sensu BURCKHARDT et al. (2023), the broadened C + Sc vein of the forewing that is not clearly demarcated from the neighbouring cell, is not clearly visible in the specimens examined. Diclidophlebia venosa differs from all seven extant Diclidophlebia species recognised by BURCKHARDT et al. (2023) in the presence of the subapically forked vein R 1, which is unusual in psyllids and, as far as known, unique in Liviinae. In two of the four specimens at hand a second fork on R 1 is developed on one or on both wings, but then asymmetically. The asymmetrical nature of this extra-vein suggests that this constitutes an abnormal feature. Specimens with abnormal venation are sometimes also found in extant psyllids. Diclidophlebia venosa resembles D. fremontiae (KLYVER, 1930) in the unpigmented, elongate oval forewings with the vein M longer than M 1 + 2, and with the long cell cu 1, the apically barely expanded metatibia with apical spurs not located on processes, and its occurrence in the New World. These characters indicate a close phylogenetic relationship between the two species. Diclidophlebia venosa sp. nov. differs from D. fremontiae in the presence of black spots at the apices of the veins along the forewing margin, the greater number of metatibial spurs (1 + (2 – 3) in the latter), the longer male subgenital plate, the apically stronger and more abruptly narrowed paramere and the longer female terminalia without the upturned apex of the proctiger. The six Old World species have either pigmented forewings (D. eastopi VONDRÁČEK, 1964, D. excetrodendri (LI & YANG, 1991), D. harrisoni OSISANYA, 1969 and D. oceanica (CRAWFORD, 1919 )), the vein M 1 + 2 distinctly longer than M (D. eastopi, D. leptonychiae BURCKHARDT et al., 2006 and D. oceanica) or have an apically clearly widened metatibia with apical spurs on processes (D. eastopi, D. harrisoni, D. leptonychiae, D. oceanica, and Diclidophlebia xuani MESSI in MESSI et al. 1998).	en	Burckhardt, Daniel, Drohojowska, Jowita, Štarhová Serbina, Liliya, Malenovský, Igor (2024): First record of jumping plant lice of the family Liviidae (Hemiptera, Sternorrhyncha, Psylloidea) from Dominican amber.

03E387941577FF92FF3EFAA7FC1C2873.taxon	discussion	Comments: The new species has the following characters which diagnose Klyveria within the Liviinae (BURCKHARDT et al. 2023): head with moderately to strongly transverse vertex and subspherical, collared eyes; metatibia with an apical crown of weakly sclerotised spurs, without strong spurs laterally; female terminalia slender and relatively long, subgenital plate with a narrow apical process. Klyveria sucina differs from K. crassiflagellata (BURCKHARDT, 1996) and K. setinervis (BURCKHARDT, 1996), the only described species of the genus (BURCKHARDT 1996), in the relatively longer head, slender antennal segment 3, and in following details of the forewing: cell c + sc broad (rather than narrow), vein M shorter than M 1 + 2 (rather than longer) and vein Cu shorter than Cu 1 b (rather than longer). The meracanthus of K. sucina is slender and tubular rather than horn-shaped as in the other Klyveria species. This is probably an artefact due to compression of the specimen. The delimitation of vein C + Sc towards the cell is difficult to see in the two specimens at hand of the new species. This makes it difficult to judge whether the species differs in this character from other congeners. According to BURCKHARDT et al. (2023) the metatarsal segments in Klyveria are relatively short, but in the fossil species they are moderately long. This character is apparently more variable than suggested by BURCKHARDT et al. (2023) and the generic diagnosis needs to be amended.	en	Burckhardt, Daniel, Drohojowska, Jowita, Štarhová Serbina, Liliya, Malenovský, Igor (2024): First record of jumping plant lice of the family Liviidae (Hemiptera, Sternorrhyncha, Psylloidea) from Dominican amber.

03E387941574FF9CFCBBFAA7FB812B12.taxon	discussion	Comments: In general habitus, in the venation of the forewings (with the vein C + Sc, which is not widened and clearly delimited from the neighbouring cell, and a uniform membranous pterostigma), in the structure of the hind legs (with several indistinctly grouped, sclerotised apical spurs on metatibiae) and in the female terminalia, the new species is similar to extant Neotropical species of Melanastera (BURCKHARDT et al. 2023). Melanastera casca differs from the described Melanastera species in the pterostigma of the forewing with mostly subparallel margins rather than widened in the apical third. The characteristic pterostigma shape in M. casca is shared by M. vetus BURCKHARDT & DROHOJOWSKA sp. nov. and four undescribed species from southern and southeastern Brazil associated with Asteraceae (hosts confirmed for three species by the presence of immatures and likely for one species). The four extant species will be described in a monograph on the Paurocephalini from Brazil (SERBINA et al. 2024). Melanastera casca differs from M. vetus by the much longer cell cu 1 of the forewing and the shorter, more robust female terminalia. From the extant species associated with Asteraceae, M. casca differs in the broader forewings (2.2 versus> 2.4) and the relatively short female proctiger with an almost straight dorsal outline (versus relatively long with a distinctly sinuate or concave dorsal outline).	en	Burckhardt, Daniel, Drohojowska, Jowita, Štarhová Serbina, Liliya, Malenovský, Igor (2024): First record of jumping plant lice of the family Liviidae (Hemiptera, Sternorrhyncha, Psylloidea) from Dominican amber.

03E38794157BFF9DFF35FF76FACC2F49.taxon	description	Description: Adult: Colouration. Dark brown. Antenna entirely dark brown. Forewing veins and pterostigma dark brown; membrane colourless, transparent with brown patches at the apex of veins along wing margin. Structure. Head, in dorsal view, wider that pronotum, slightly narrower than thorax, moderately transverse (Fig. 1 F, 5 A). Vertex subrhomboidal; passing smoothly into genae anteriorly; coronal suture fully developed; median ocellus not visible; compound eyes, in dorsal view, hemispherical, appressed to head. Antenna 10 - segmented, slightly longer than head width; subdivisions only partly visible; relative lengths of antennal segment 10 and terminal setae as 1.0: 0.6: 1.0. Metacoxa (Fig. 5 B) with blunt, tubular meracanthus. Metatibia longer than metafemur, widened apically; bearing sclerotised apical spurs, their number and grouping is not visible (Fig. 5 B). Metatarsal segments moderately long, subequal in length. Forewing (Fig. 1 F, 5 C, D) oval, widest in the middle; membranous; vein C + Sc moderately, evenly curved, slender, distinctly delimited to cell; cell c + sc relatively wide; costal break developed, close to apex of vein R 1; pterostigma moderately wide, with subparallel margin in the median third, not expanded in apical third; entirely membranous; nodal line developed; vein R slightly shorter than M + Cu; vein Rs mostly straight, weakly curved to costal margin subapically; vein M much longer than M 1 + 2; vein Cu 1 a straight at base, curved towards anal margin subapically; in one wing a crossvein m-cu 1 a is developed (Fig. 5 C); veins M 1 + 2 and M 3 + 4 oblique to wing margin apically; cell cu 2 moderately long; anal break adjacent to apex of vein Cu 1 b; surface spinules not visible. Male unknown. Female terminalia (Fig. 5 E) cuneate; proctiger weakly concave dorsally, apex subacute, slightly upturned; beset with long setae across the middle and shorter setae apically; subgenital plate almost straight ventrally, acute apically. Measurements (in mm): Head width 0.73; antenna length 0.8; forewing length 1.6; metatibia length 0.5; female proctiger length 0.43.	en	Burckhardt, Daniel, Drohojowska, Jowita, Štarhová Serbina, Liliya, Malenovský, Igor (2024): First record of jumping plant lice of the family Liviidae (Hemiptera, Sternorrhyncha, Psylloidea) from Dominican amber.

03E38794157BFF9DFF35FF76FACC2F49.taxon	discussion	Comments: Melanastera vetus shares with M. casca and four undescribed Brazilian species associated with Asteraceae (SERBINA et al. 2024) the pterostigma of the forewing with subparallel margins (see also comments under M. casca). It differs from M. casca in the forewing with dark dots at the apices of the veins along the margin and a shorter cell cu 1, as well as in the longer, dorsally concave female terminalia. From the extant species, M. vetus sp. nov. differs in the broader forewings (2.4 versus ≥ 2.5) with dark dots, which are restricted to the apices of the veins along the margin but are otherwise absent from the cells. In the extant species associated with Asteraceae, the dark dots on the forewings are either completely absent or present on most cells.	en	Burckhardt, Daniel, Drohojowska, Jowita, Štarhová Serbina, Liliya, Malenovský, Igor (2024): First record of jumping plant lice of the family Liviidae (Hemiptera, Sternorrhyncha, Psylloidea) from Dominican amber.
