(Figs 1–2)
Type material. HOLOTYPE: ♂ (RMNH), PORTUGAL: GUARDA DISTRICT (formerly Beira Alta Province): Serra da Estrela, 3 km S Manteigas, 1000 m, deciduous forest, 9.v.1994 (P. Oosterbroek & C. Hartveld leg.), labelled ‘PORTUGAL Beira Alta / Serra da Estrêla / P.Oosterbroek / & C.Hartveld’ // ‘ 3 km Z MANTEIGAS / decid. forest 1000 m / 9 V 1994 ST.31’ [both printed, white labels] // ‘HOLOTYPE / Limonia / hartveldae sp. n. ♂ / J. Starý 2017’ [printed, red label]. The specimen is micro-pinned on a stage of polyporus, all legs attached but of hind left leg only femur is present; apex of abdomen cut off, terminalia dissected and placed in a sealed plastic tube with glycerine, pinned with the specimen.
PARATYPES: 2 ♂♂, same data as for holotype (RMNH, JSOC). Both specimens micro-pinned.
Diagnosis. Medium-sized species. Body colouration in general dark brown, with paler areas, especially on pleuron. Wing membrane slightly tinged with brownish grey. Wing pattern diffuse but distinct. Male terminalia with aedeagus of moderate length and breadth and paramere moderately emarginated at posterior margin, with its inner process subacute at tip. Body length 7.8–8.5 mm, wing length 8.1–9.8 mm.
Description. Male. Head dark brown to black, suffused with grey pruinosity on frons and vertex, somewhat shiny on rostrum. Palpus dark brown. Antenna 14-segmented, moderately long, reaching to about base of wing, dark brown. Flagellomeres elongate, subcylindrical. Longest verticils very long, about five times as long as their respective flagellomeres.
Thorax generally dark brown. Pronotum dark brown throughout. Prescutum and scutum with dark brown median area demarcated with prescutal setae, and with dark brown patch laterally; interspaces slightly paler. Scutal lobes dark brown, with yellowish brown area in between. Scutellum yellowish brown anteromedially, otherwise dark brown. Mediotergite yellowish brown anterolaterally, rest dark brown. Pleuron generally dark brown, with paler areas on anepimeron, laterotergite, and around base of wing and halter. Wing moderately broad, with width-length ratio about 1: 3.5. Wing membrane slightly tinged with brownish grey. Wing pattern consisting of three darker spots at anterior margin, more or less diffuse but distinct, at origin of Rs, at tip of Sc 1, and over R 2 (= cross-vein r) (pterostigma). Diffuse, darker seams along veins, especially Cu and so-called outer cord (series of subvertical vein elements, including base of discal cell, at about two thirds length of wing). Venation usual for Limonia, with discal cell moderately long; M 3+4 (lower margin of discal cell) and M 4 subequal in length. Halter with pale stem, slightly darker on knob. Legs generally yellow, with coxae, especially fore ones, darker, brown; femora fading from yellow to yellowish brown distally, with pale subapical and dark apical rings; tarsi dark brown, with tarsomeres 1 slightly longer than rest of tarsi.
Abdomen generally dark brown, with anterior margins of tergites narrowly yellowed; tergites 1 and 8 often dark brown throughout; ventral side paler, with yellow areas on sternites larger. Male terminalia (Figs 1–2) dark brown. Tergite 9 essentially semicircular in outline. Its posterior margin broadly rounded, formed by chitinized bar, with shallow, rather V-shaped median notch. Gonocoxite usual in length and breadth. Gonostylus conical, rather long, evenly arched and tapered to subacute tip, not markedly swollen in proximal half. Aedeagus of moderate length and breadth, moderately enlarged in proximal half, with another slight enlargement before apex. Paramere moderately emarginated at posterior margin, with its inner process rather broad at base, subacute at tip.
Female unknown.
Differential diagnosis. According to SAVCHENKO (1985), the new species belongs to the L. flavipes species group and seems to be most similar to European species, such as Limonia sylvicola (Schummel, 1829) and L. taurica (Strobl, 1895). Its body colouration and wing pattern are, however, distinctly darker. The male terminalia have the gonostylus rather long and slender and the inner process of the paramere subacute at the tip, whereas, in both L. sylvicola and L. taurica, the gonostylus is shorter and broader and the inner process of the paramere rounded at the tip.
Etymology. The new species is named in honour of one of its collectors, Cita Hartveld (Amsterdam, The Netherlands) who, together with Pjotr Oosterbroek, has made extensive collections in the Mediterranean. A noun in genitive singular.
