Lichtwardtia Enderlein, 1912


Genus Lichtwardtia Enderlein, 1912 

Lichtwardtia  Enderlein, 1912: 406. Type species: Lichtwardtia formosana  Enderlein, 1912 (original designation).

Vaalimyia  Curran, 1926: 398. Type species: Vaalimyia violacea  Curran, 1926 [= Dolichopus angularis  Macquart, 1842] (original designation).


The generic synonymy list is as given by Yang et al. (2005) except that Lichtwardtia formosana  Enderlein, 1912 was considered to be a junior synonym of L. ziczac  ( Wiedemann 1824); it is confirmed a valid species in this work.


Small to medium-sized species (3.5-5.0 mm). Head: overall dark metallic green including vertex, with thick pale pollinosity; face wide, slightly narrow at middle, slightly raised from lateral view, frons and face both with thick pale pollinosity that hiding the ground colour, face parallel sided, but slightly narrowed near mid-length. Hairs and bristles on head black but lower postocular bristles pale. Vertex flat. Ocellar tubercle distinct. With pairs of strong vertical and diverging ocellar bristles present, with weak postvertical bristles which are approx. a half-length of vertical bristles. Antenna wholly or mostly yellow; scape with short dorsal bristles, longer than pedicel; arista-like stylus dorsal, two-segmented, with feather-like long hairs on apical segment. Eyes dichoptic, with hairs between facets. Clypeus long and wide.

Thorax: dark metallic blue-black. Metapleuron with one narrow black stripe. Hairs and bristles on thorax black. Acr biseriate, hair-like. Five strong pairs of dc. With one pa, two sa, one sr, one hm, one pm, two npl. Propleuron with long curved bristle just above base of fore coxa. With hairs anterior to spiracle. Scutellum with two pairs sc, apical pair long and strong, basal pair short and weak. Mid and hind coxae with outer bristle(s). Fore femur without distinct bristle. Mid and hind femora each with preapical bristle. Hind femur thick, 5.0 times longer than wide. Hind tarsomere I with strong dorsal bristles, shorter than hind tarsomere II.

Wing: usually clear, sometimes with faint brown clouding around distal vein M and dm-cu crossvein, occasionally partly smoky. Vein costa sometimes widened at the joint with R1, with various callus. M with fading M2, M1 with one short subvein. Crossvein dm-cu straight. Vein M joining margin just before apex. CuAx around 1.0.

Abdomen: metallic green (in Oriental), nearly 1.5 times longer than wide, with pale pollinosity. Hairs and bristles on abdomen black.

Male terminalia: Epandrium distinctly longer than wides. Epandrial lobe with three long pale bristles Cercus nearly triangular, margin rounded, usually pale with broad black outer margin, with weak digitations around outer margin, with black simple or specialised marginal bristles on digitations.
