Abstract: Porricondyla acutistylata sp. nov. urn:lsid:zoobank.org:act: EFBAACCE-1703-484C-BF57-1F2133CE4B98 Fig. 22 Diagnosis Morphology The gonostylar tooth of P. acutistylata sp. nov. is comb-shaped, i.e., consists of numerous individual spines with a common, conjunctive base, which places this species in subdivision A of Jaschhof & Jaschhof’s (2013) intrageneric classification. Within that subdivision, the new species is characterized by a set of terminalia characters, as follows (Fig. 22A). The gonostylus is both markedly bent and tapered towards the apex (↓ 1); the long, slender and for the most part moderately sclerotized parameres have conspicuously pale, strongly bent apices (↓ 2); and the large, broadly rounded gonocoxal processes are completely membranous (↓ 3). Larvae and females of the new species are unknown. DNA barcode The CO1 sequence (652bp) of the holotype specimen is available in BIN BOLD:AER2210. Search on BOLD’s BIN Database retrieved no further result for this BIN (accessed 27 Aug. 2023). Etymology The specific name, an adjective, means ‘with pointed gonostylus’. Type material Holotype GERMANY • ♂; Bavaria, Weilheim, Pähl, Hartschimmelhof; 47°93′99″ N, 11°18′30″ E; 20 Jun.‒12 Jul. 2020; D. Doczkal and K. Grabow leg.; Malaise trap; fen; BOLD GBDTA9910-21; ZSM-DIP-42303-C06. Other characters Male BODY LENGTH. 2.0 mm. HEAD. Eye bridge dorsally 1‒2 ommatidia long. Antenna markedly longer than body; scape and pedicel brighter than flagellum; circumfila present on flagellomeres 1‒14; neck of fourth flagellomere 1.8× as long as node (Fig. 22B). Palpus concealed in only specimen available for study. THORAX. No scutal windows. Pronotal setae 4, anepisternal setae 0, anepimeral setae 7. WING. Markedly longer than body. Length/ width ratio 2.8. LEGS. Foreleg with femur 0.9× length of tibia, T 2 not retained. Acropods not retained. TERMINALIA (Fig. 22A). Gonocoxal synsclerite with subtriangular protuberances ventroapically; ventral emargination very broadly U-shaped; a large, narrowed portion anteriorly with only a few, mostly lateral setae; anterior margin broadly rounded. Parameres with unusually broad transverse bridge subbasally. Aedeagal apodeme including its extensive membranous apex as long as gonocoxae, for the most part moderately sclerotized; ducts of accessory glands evident (not illustrated).
