Diagnosis
Morphology
The male of P. lobata sp. nov. is characterized by the gonostylus whose thick basal portion extends apicodorsally into an elongate-subtriangular process (↓ 1, Fig. 21A), and by the H-shaped tegmen whose lateral pillars are markedly bent dorsad beyond the cross connection (↓ 2, Fig. 21A). Larvae and females of the new species are unknown.
DNA barcode
CO1 sequences (642‒652bp) were obtained of four paratype specimens detailed below and allocated to three different BINs: BOLD:ADW4641 (specimen ZSM-DIP-42305-E05), BOLD:AEO7433 (ZSM-DIP-42306-A08), and BOLD:AEE7552 (ZSM-DIP-42306-G02 and ZSM-DIP-42306-G07). Morphological evidence in support of the genetic clustering was not found (see the remarks below). Search on BOLD’s BIN Database retrieved a further match for BIN BOLD:AEE7552, as Cecidomyiidae sp. from Bavaria, Germany (accessed 27 Aug. 2023).
Etymology
The Latin adjective ‘ lobata ’, for ‘lobate’, refers to the peculiar structure of the gonostylus.

Other characters
Male
BODY LENGTH. 1.5‒2.0 mm.
HEAD. Eye bridge dorsally 3‒4 ommatidia long. Antenna markedly longer than body; scape and pedicel brighter than flagellum; circumfila present on flagellomeres 1‒13; neck of fourth flagellomere 2.0‒2.2 × as long as node (Fig. 21B). Palpus 4-segmented, slightly longer than head height.
THORAX. Scutal setae sparse. Anepisternal setae 0‒4.
WING. Longer than body. Length / width ratio 2.9‒3.2.
LEGS. Claws with large tooth basally. Empodia ⅓ as long as claws.
TERMINALIA (Fig. 21A). Gonocoxal synsclerite: ventral emargination deeply U-shaped, reinforced basally; setose portion below emargination very short; anterior margin membranous, of varying outline. Gonostylus: medial bulge subglobular, with 2‒3 ordinary setae and 1 long bristle below pectinate tooth. Aedeagal apodeme markedly longer than gonocoxae, moderately sclerotized; both base and apex broadened, apical broadening subrectangular, slightly sclerotized; ducts of accessory glands evident (not illustrated).
Remarks
The new species exhibits morphological variation to the same, normal extent as found in other Parepidosis (Jaschhof & Jaschhof 2013). The confusing thing about P. lobata sp. nov. is that, in slide-mounted specimens examined ventrally, the length of the tegminal processes varies depending on how strongly the tegminal apex is bent dorsally under the pressure of the cover slip (Fig. 21A, C).
