Figs 11–12
Diagnosis. Males of L. baltica are largely similar to Polyardis males, with the exception of the genitalia. Genitalic characters specific to L. baltica are the same as for the genus (see the generic diagnosis and Fig. 12).
Male characters. Body size 1.1–1.2 mm. Head. Postfrons with a single pair of setae. Eye bridge 1 ommatidium long laterally, 2–3 ommatidia dorsally. 3 postocular bristles. Scape slightly larger than pedicel. Hair-shaped translucent sensilla on flagellomeres 1–11. Neck of fourth flagellomere markedly longer than node; node with 1 complete and 2 incomplete crenulate whorls of sensory hairs, 1 whorl of short setae basally, a variable number of hair-shaped translucent sensilla distally (Fig. 11). Palpus shorter than head height, 3-segmented; first segment thick, with hair- shaped translucent sensilla; second and third segments subcylindrical. Thorax. Pronotum setose. Scutum with lateral and dorsocentral stripes of setae. Wing. R 1 2.0–2.5 times as long as Rs. M 1+2 weak but continuous to the wing edge. Hind fork distinct, nearly rectangular. Legs with more setae than scales, scales narrow, those on tarsi shorter and broader. Claws sickle-shaped, toothless. Empodia as long as claws. Genitalia (Fig. 12). Ninth tergite shortened medially. Gonocoxal synsclerite slightly broader than long, markedly narrowed towards the base; ventral portions with setae of various lengths excepted a non-setose margin anteriorly; ventral emargination deep, V-shaped; medial bridges slightly bulging, densely setose; dorsal transverse bridge conspicuously narrow with rounded, somewhat irregular anterior edge. Gonostylus dorsoventrally flattened, in ventral view slender, clearly tapered towards the apex with fingernail-shaped tooth; 2 strong, short bristles subapicomedially. Tegmen large, apparently more strongly sclerotized compared with Polyardis, nearly parallel-sided for most of its length; apex narrowed into a sclerotized collar (↓ 1); parameral apodemes enlarged into semicircular lobes (↓ 2). Aedeagal apodeme about as long as the parallel-sided portions of tegmen, strongly sclerotized; the basal, rod-like portion occupying about two thirds of total length; apex usually slightly notched. Hypoproct hardly traceable, present as a pair of soft, membranous bodies without microtrichia, if correctly interpreted. Cerci, although smaller than in most other Micromyini, unusually strong and protruding ventrally, with dense microtrichia and a few posterior setae (↓ 3).
Etymology. The Latin adjective baltica refers to the occurrence of this species in Europe’s Baltic region.
Type material. Holotype. Male, Sweden, Skåne, Simrishamn, Stenshuvud National Park, old-growth beech forest, 26 May–28 June 2010, Malaise trap, M. & C. Jaschhof (spn. CEC 2779 in NHRS). Paratype. 1 male, same data as the holotype (spn. CEC 2780 in SDEI).
