Diagnosis
The ventroposterior edge of the gonocoxites has a V-shaped emargination flanked by subtriangular lobes of moderate size (↓ 1, Fig. 3A); the posteromedial protuberance has a slightly sinuous edge and a pair of ovate substructures, whose outline may remind one of eyeglasses (↓ 2, Fig. 3A). The roughly H-shaped tegmen is provided with a pair of posterolateral processes whose spike-bearing apices are bent ventrolaterally (↓ 3, Fig. 3D). The vestiture of the ninth tergite (Fig. 3A) consists of normal setae and microtrichia; megatrichia are absent.
Etymology
The specific epithet refers to Tomelilla, a small town in Sweden’s province Skåne, where the holotype specimen was collected.
Material examined
Holotype SWEDEN: ♂, Skåne, Tomelilla, Drakamöllan, grassy heathland, 29 Apr.–19 May 2004, Malaise trap, Swedish Malaise Trap Project leg. (trap 38, collecting event 599) (NHRS, no. CEC 1406).
Paratype SWEDEN: ♂, Öland, Borgholm, Rönnerum-Abbantorp Nature Reserve, small bushy fen within broadleaf forest,, 16 Jul.–21 Aug. 2015, Malaise trap, M. and C. Jaschhof legs (SDEI, no. CEC1407).
Differential diagnosis
Glemparon tomelilla sp. nov. differs from G. sagittifer, the only congener in the Palearctic, in the outline of the posterior gonocoxal edge, the structuring of the tegmen, and the more slender gonostylus. Furthermore, G. sagittifer has metepimeral setae, which are missing in G. tomelilla sp. nov. A species with genitalic structures generally similar to that of G. tomelilla sp. nov. is G. warra sp. nov. from Tasmania (Fig. 20 A–D).
Other characters
BODY SIZE. 1.6–1.7 mm.
HEAD. Eye bridge 2–3 ommatidia long dorsally. Flagellomeres 14; apical flagellomere simple (holotype) or obviously merged of two bodies (paratype); neck of fourth flagellomere 0.8 times the node (Fig. 1H). Palpus shorter than head height, 4 setae-bearing segments; first segment smallest of all; second segment slightly swollen, which is more pronounced in the paratype (Fig. 1E) compared with the holotype (Fig. 1D).
THORAX. Pronotal setae absent.
WING. Length /width ratio 2.8. Rs long, one third of apicR 1.
LEGS. Basitarsal spines absent.
TERMINALIA. Gonocoxites with narrow, unsetose, separate section ventrobasally; medial bridges clearly convex, in close distance to each other (Fig. 3A). Gonostylus 2.5 times longer than broad; densely setose except the concave portions medially and the somewhat angular-shaped, densely microtrichose apex (Fig. 3B). Ejaculatory apodeme with large, membranous, arrow-shaped apex (Fig. 3C).
Distribution and phenology
This species is known from two locations in southern Sweden, where only two specimens were obtained as a result of extensive Malaise trapping all over Sweden by both the Swedish Malaise Trap Project and ourselves for several years. A common feature of the two collecting sites is that grasses predominate in the ground cover, with one of the sites being markedly dry, the other rather swampy. Specimens were collected during the main vegetation period in May–August.
