Planetella galiciensis Ševčík & Hippa sp. nov.
( Figs 10A,B View Fig , 14D View Fig )
Type material. HOLOTYPE: J, Spain, Galícia, Fragas do Eume Natural Park , 150 m, 16.–30.v.2019, Malaise trap 2, leg. María J. Servia & J. Ševčík, specimen after DNA extraction, prepared on slide, No. PLA19 (coll. NMPC).
DNA sequences. DNA sequences (COI barcode region, 28S, 16S) taken from the holotype (No. PLA 19) are deposited in GenBank. Their Accession numbers are provided in Table 1.
Diagnosis. This is the only European species of Planetella with 22 flagellomeres and uniform orange brown coloration. Male terminalia ( Figs 10A,B View Fig ) with gonocoxite three times as long as broad, aedeagus longer than gonocoxite, gonostylus narrow, more than half as long as gonocoxite, apically with a pointed tooth.
Etymology. This species is named after Galícia, northern Spain, where the holotype was collected; adjective.
Description. Male. Wing length 6.8 mm. Overall body coloration mostly reddish brown, with legs and halters lighter.
Head. Eyes narrowly connected with eye-bridge.Antennal flagellum with 22 binodal tricircumfilial flagellomeres, the apical one with a short uninodal appendage lacking circumfila. Flagellomere 1 ( Fig. 14D View Fig ) 3.2 times as long as broad, slightly longer and less constricted but of similar shape as the other flagellomeres, flagellomere 4 ( Fig. 14D View Fig ) 2.9 times as long as broad. Left flagellomere 2 in holotype with an aberrant medial projection. Maxillary palpus short, with 3 palpomeres, the apical palpomere about twice as long as the previous one.
Thorax mostly reddish brown. Scutum with three longitudinal darker stripes. Scutellum dark brown. Laterotergite darker in upper part. Both scutum (anteriorly) and scutellum lined with black curved lateral stripes. Scutum distinctly produced above the head.
Wing elongated, about 3 times as long as broad. Veins C, R 1, R 5 and Cu-stem dark and distinct. R 1 joining C almost in the middle of wing. R 5 reaching C beyond wing apex. Rs indistinct. M 4 light. CuA with dark stem and distally bent downwards.
Legs with tarsal claws about 1.5 times as long as maximum tarsal diameter, gradually bent.
Abdomen brownish, with a light oval spot on each side of the tergite.
Terminalia ( Figs 10A,B View Fig ). Gonocoxite relatively narrow, about three times as long as broad, mediobasally with a broad lobe. Gonostylus very narrow, only slightly curved, evenly broad throughout, 4.7 times as long as broad, short- er than gonocoxite, apically with a pointed, transversely grooved dark lobe. Cerci short, apically rounded, basally fused. Hypoproct relatively broad, subrectangular, basally broader, distinctly longer than cerci. Aedeagus narrow, elongate, apically pointed, as long as gonocoxites. Gonocoxal apodemes strongly sclerotized, medially fused.
Female. Unknown.
Biology. Unknown. The holotype was collected in the Atlantic coastal forest, along a small forest brook joining the river Eume.
Discussion. This is the only European species of Planetella with 22 flagellomeres. The second highest number of flagellomeres (21) can be found in P. antennata sp. nov., which has, however, eyes separated and banded abdomen (see above). Its sister species in the phylogenetic tree ( Fig. 15) is P. antennata sp. nov. but its closest relative in terms of K2P genetic distance is P. fasciata , with 6.2% distance ( Tab. 3).
