FOUR NEW GENERA OF PLATYPEZIDAE

Zhang Jun-feng (Shondong Provincial Museum)  
Four new genera and five new species of flat- footed flies described in this paper were collected from the Third Member of the Laiyang Formation at Nanligezhuang and Tuanwang villages in the south Laiyang Basin of Shandong by the author in the autumn of 1984.For a long time,only a few species of insect fossils from this area were studied by C.Ping(1928).Recently,after making a de- tailed investigation,a large number of fossil in- sects have been discovered,mostly representing new forms.Besides the material described in the pre- sent paper,other fossil insects Of the Laiyang For- mation will be studied by the writer in the near furture.The Namligezhuang village lies about 21 km south to southwest of the Laiyang town in ea- stern part of Shandong,while the Tuanwang vil- lage lies about 4km south to southwest of Nanli- gezhuang(see text-fig.1).Fossil insects have ma- inly been found in the thin shale at the middle and upper parts of the Third Member of the Laiyang Formation which is a set of lake deposits(see text- fig.2).The author considers that the age of the Laiyang Formation may be Late Jurassic.Up to now,no elements of the Platypezidae have been discovered in Mesozoic all over the world. Description of new genera and species Family Platypezidae Fallen,1817 Genus Palaeopetia gen.nov. Type species:Palaeopetia laiyangensis gen.et sp.nov. Diagnosis:Venation of wing clear.Sc longer, connecting with R in middle part.Distal cell small,nearly as long as second basal in length. M(?) long and straight,branching off from M_(1÷2) at middle of wing.Anal cell small and sharp in distal part.A_2 longer,running near hind margin of wing.Tarsi of leg short.Posterior metatarsi short,a little narrower than tibiae.Lateral part of mesonotum with few and scattered bristles.Termi- nate part of tibiae with setae. Comparison:This genus somewhat resembles Opetia Meigen,but it may be separated from the latter by its distal cell,longer Sc connecting with R in middle part and longer A_2. Palaeopetia laiyangensis gen.et sp.nov. (Pl.Ⅰ,fig.1;Text-fig.3) Head absent.Thorax long,oval, with one humeral and two notopleural bristles.Scutellum semicircular,with two long distal scutellar bristles. Legs stout and shorter.Tarsi a little longer than tibiae.Posterior metatarsi somewhat narrower than tibiae,as long and broad as second segment of tar- sus.Characters of venation shown in Text-fig.3. Abdomen broadly oval,with 6 segments. Total length(excluding the head)2.70mm. Wing 2.63mm in length and 1.12mm in breadth. Posterior femus 0.48mm,tibia 0.66mm and tarsus 0.73mm in length. Horizon and locality:Third Member of Lai- yang Formation,Nanligezhuang,Laiyang. Genus Mesopetia gen.nov. Type species:Mesopetia tuanwangensis gen.et sp.nov. Diagnosis:Antennae slender,long,with short arista.Head large.Thorax stout.Venation dis- tinct.Distal cell obviously longer than second ba- sal.M_1 long and straight,with transverse vein connecting with M_2.A_2 short.Anal cell longer. Comparison:This genus differs from Palaeope- ria in the longer distal cell,in the transverse vein between M_1 and M_2,in the longer anal cell and in the shorter A_2. Mesopetia tuanwangensis gen.et sp.nov. (Pl.Ⅰ,fig.2;Text-fig.4) Head subquadrilateral.Proboscis stout,short and soft.Mesonotum raised.Scutellum evidently projecting.Femora and tibiae short,stout and with setae.Characters of venation as shown in text-fig. 4.Seventh and eighth segments of abdomen very small,curved forwards;last segment approximate- ly oval. Total length 3.76mm.Wing 2.89mm in leng- th,1.23mm in breadth. Horizon and locality:Third Member of Lai- yang Formation,Tuanwang,Laiyang. Genus Lithopetia gen.nov. Type species:Lithopetia hirsuta gen.et sp. nov. Diagnosis:Head large.Eyes dichoptic.Legs long,with long setae and hairs.Anterior meta- tarsi very long;posterior metatarsi short.Sc en- ding at middle of costal margin of wing.R en- ding at two-thirds of costa.Rs clear,thin.M,CuA and A too faint to identify.Abdomen consisting of 5 segments. Comparison:This new genus is similar to the living genera of Platypezidae in the characters of Sc,R and Rs veins,but it can be distinguished from them by the very faint M,CuA and A,very long anterior metatarsi and short posterior meta- tarsi. Lithopetia hirsuta gen.et sp.nov. (Pl.Ⅰ,figs.3,4;Text-fig.5) Proboscis spreading forwards.Eyes large,ap- proximately round.Thorax broadly oval,with four postalar and one lateral scutellar bristles.An- terior femora clearly stouter and shorter than ti- biae;the latter with long hairs in terminate part. Posterior femora a little stouter and shorter than tibiae;the latter with a line of setae and a line of long hairs.Metatarsi as broad as tibiae and second segment of tarsus,as long as the latter in length; both with long hairs.Characters of venation as shown in Text-fig.5.Abdomen long egg-shaped, displaying darker colour on fifth segment. Total length 3.22mm.Wing 2.83mm in leng- th,and 1.27mm in breadth.Posterior femus 0.61 mm,long,tibia 0.83mm and tarsus 0.94mm in length. Horizon and locality:Third Member of Lai- yang Formation,Nanligezhuang,Laiyang. Genus Psedopetia gen.nov. Type species:Pseudopetia grandis gen.et sp. nov. Diagnosis:Head large,triangular.Eyes large, dichoptic.Antennae short cone-shaped.Legs stout and short.Posterior metatarsi a little narrower than tibiae.Costa of wing with setae.Sc short and dissociated.R stout and long.Other veins too faint to identify.Abdomen with 8 segments. Comparison:This genus is very particular in the characters of venation and the short cone-shaped antennae,but with two branches of Rs and three branches of M.It is necessary to make a furture study on the taxonomy of the family to which Pse- udopetia should belong. Pseudopetia grandis gen.et sp.nov. (Pl.Ⅰ,fig.5;Text-fig.6) Head with long bristles.Antennae very short, clearly slender in terminate part.Thorax broadly oval,with four notopleural and two postalar bris- tles.Anterior femora stouter and shorter than ti- biae;the latter with few scattered long setae as long as tarsi.Metatarsi as long as second and third segments added together.Posterior femora distinctly stouter and shorter than tibiae;the lat- ter with few and scattered long setae in distal part, nearly as long as tarsi.Metatarsi a little narrower than tibiae,obviously broader than second segment and two times as long as the latter.Characters of venation as shown in Text-fig.6. Total length 3.00mm.Wing 2.77mm in leng- th and 1.05mm in breadth.Posterior femus 0.33 mm,tibia 0.83mm and tarsus 0.84mm in length. Horizon and locality:Same as that of the pre- ceding species. Pseudopetia exilis sp.nov. (Pl.Ⅰ,figs.6;Text-fig.7) Antennae distinctly shorter than head in leng- th,sharp in terminate part.Eyes nearly connec- ting.Thorax more or less round.Anterior femo- ra nearly as long and broad as tibiae,with the latter as long as tarsi.Posterior femora shorter than tibiae,evidently narrower than distal part of the latter.Tarsi a little longer than tibiae and metatarsi as long and broad as second segment. Characters of venation as shown in Text-fig.7. Sixth and seventh segments of abdomen very short, distal part of eighth segment being rent in two. Total length 1.96mm.Wing 1.62mm in leng- th and 0.72mm in breadth.Posterior femus 0.31 mm,tibia 0.43mm and tarsus 0.46mm in length. Comparison:The new species is very close to P.grandis,but can be distinguished from the lat- ter by its longer Sc,short and sharp antennae, shorter metatarsi of fore and hind leg. Horizon and locality:Third Member of Lai- yang Formation,Tuanwang,Laiyang,Shandong.
