The Porricondylini (Diptera: Cecidomyiidae: Porricondylinae) of Sweden revisited: descriptions of nineteen new species of ten genera, including a new genus Author Jaschhof, Mathias Author Jaschhof, Catrin text Zootaxa 2020 2020-01-22 4728 2 151 182 journal article 24288 10.11646/zootaxa.4728.2.1 15784c76-41dc-47a2-aad7-db1b284033d1 1175-5326 3621083 3E13B249-1123-4CA9-85BE-62C5F2835B21 Porricondyla ottenbyensis sp. nov. Figs 40–41 Diagnosis. This new Porricondyla has a platelike gonostylar tooth, a condition classifying it in species group C ( Jaschhof & Jaschhof 2013: 233 ff.). A peculiarity of P. ottenbyensis is the bifurcate apices of the parameres ( Fig. 41 , ↓ 1 ). Porricondyla bifurcata Mamaev is only faintly similar in having the right paramere deeply split into two branches while the left paramere is entire ( Mamaev & Zaitzev 1996 : fig. 1). All other Porricondyla have entire, single-pointed parameres. Females and larvae of P. ottenbyensis are unknown. Other male characters. Body size 1.9 mm . Head. Eye bridge 7–8 ommatidia long at vertex. Antenna with only 11 flagellomeres retained, all with circumfila. Scape and pedicel concolorous with flagellum. Neck of fourth flagellomere 1.8 times as long as node ( Fig. 40 ). Palpus 1.6 times as long as head height, 4 setose, subcylindrical segments, apical segment longest of all. Thorax. Presutural windows distinct. Pronotal setae 7; anepisternal setae 3; anepimeral setae 3. Wing longer than body. Length / width ratio 2.7. M 1+2 absent. Hind fork nearly complete. Legs. Femur and tibia of foreleg equally long. Tarsi and acropods missing. Genitalia ( Fig. 41 ). Gonocoxal synsclerite: most of ventral surface setose, although sparser medially; narrowed ventrobasal portion moderately long; ventral emargination U-shaped, slightly reinforced basally; processes broad, largely membranous, only basolaterally reinforced; ventrobasal edge straight; dorsal apodemes moderately long, ending close to ventrobasal edge. Gonostylus elongate in a ventral view, 3 times as long as broad, broadest subbasally, then evenly tapered towards apex; 3–4 inconspicuous, long bristles mediosubapically. Parameral apices oriented laterally. Aedeagal apodeme about as long as gonocoxae, both base and apex unmodified. Posterior ends of accessory gland ducts well discernible. Etymology. The species epithet refers to Ottenby Nature Reserve, located at the southern tip of the island of Öland, southeast Sweden . The type locality, Södra lunden, is a large, varied woodland with intermittent haymeadows, which is grazed by both cattle and fallow deer, the latter introduced long ago as royal game. Type material.
