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’.

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).
