description: Klyveria sucina BURCKHARDT & DROHOJOWSKA sp. nov.
Fig. 1C, D, 3
LSID: urn:lsid:zoobank.org:act:7FE418DF-D9EB-4081-A0BC-779B2530276E
Etymology: From the Latin adjective sucinus (1 st /2 nd declension) = of amber, referring to the origin of the species from amber.
Holotype: Female specimen, sample #D-14-1146 (AMNH).
Paratype: One female, sample #31(1) (GPAC).
Type locality: Dominican Republic, Cordillera Septentrional.
Description: Adult: Colouration. Light brown. Antenna brown, segments 4–8 with apical third dark brown and segments 9 and 10 entirely dark brown. Metascutum with two brown sublateral dots on either side. Forewing colourless, transparent with dark apices of veins along apical wing margin.
Structure. Vertex (Fig. 1 C, 3 A) rhomboidal, transverse, 2.5 times as wide as long; passing smoothly into genae anteriorly; coronal suture not visible basally; genae not enlarged into processes; frons small, trapezoidal (Fig. 1 D); median ocellus visible in perpendicular view to vertex; compound eyes, in dorsal view, subglobular, slightly collard. Clypeus pear-shaped, large, flattened ventrally (Fig. 1 D). Antenna 10-segmented, longer than head width; relative length of flagellar segments as 1.0: 0.4: 0.4: 0.4: 0.3: 0.3: 0.4: 0.2; terminal setae not visible. Pronotum, in dorsal view, hardly curved posteriad laterally, 0.6 times as long as vertex along median longitudinal body axis. Metacoxa (Fig. 3 B) with slender subacute horn-shaped meracanthus. Metatibia (Fig. 3 B) much longer than metafemur, hardly widened apically; lacking sclerotised spurs along its length; bearing a posteriorly open crown of densely spaced apical, weakly sclerotised spurs. Both metatarsal segments moderately long, subequal in length. Forewing (Fig. 3 C) oval, widest in the middle; 2.3 times as long as wide, membranous; vein C+Sc evenly curved, delimitation to cell not clearly visible; cell c+sc wide; costal break developed, close to apex of vein R 1; pterostigma indistinct, not clearly visible; nodal line developed; veins R and M+Cu subequal; vein Rs almost straight; vein M shorter than M 1+2; vein Cu 1a strongly curved towards anal margin; veins M 1+2 and M 3+4 almost perpendicular to wing margin apically; vein Cu shorter than Cu 1b; anal break adjacent to apex of vein Cu 1b; surface spinules not visible. Hindwing almost as long as forewing. Male unknown. Female terminalia (Fig. 1 D, 3 D) partly damaged; both proctiger and subgenital plate with massive base and slender apical process.
Measurements (in mm): Head width 0.6; antenna length 0.9; forewing length 1.5; metatibia length 0.5; female proctiger length 0.28.
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 1b (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.
