Diagnosis

Morphology

This new Porricondyla differs from congeneric species in the unusually large and strongly flattened gonostylus ( Fig. 27A ). The fairly large tooth at the gonostylar apex transitions dorsally into a finely serrate margin (↓ 1, Fig. 27A ). Larvae and females of P. plana sp. nov. are unknown.

DNA barcode

The CO1 sequence (640bp) of the paratype specimen detailed below is available in BIN BOLD:AEO7191. Search on BOLD’s BIN Database retrieved no further result for this BIN (accessed 27 Aug. 2023).

Etymology

The Latin adjective ‘ plana ’ means ‘flat’. The name refers to the conspicuously flattened gonostylus characteristic of this species.

Other characters

Male

BODY LENGTH. 1.9‒2.2 mm.

HEAD. Eye bridge dorsally 3‒4 ommatidia long. Antenna slightly longer than body; scape and pedicel brighter than flagellum; circumfila present on flagellomeres 1‒13; neck of fourth flagellomere 1.8× as long as unusually slender node ( Fig. 27B ). Palpus 4-segmented, slightly longer than head height, apical segment longest of all.

THORAX. Scutal windows distinct. Pronotal setae 5‒7, anepisternal setae 0‒3, anepimeral setae 3‒5.

WING. Markedly longer than body. Length/ width ratio 3.0‒3.2.

LEGS. Foreleg with femur 1.1 × length of tibia, T 2 not retained. Acropods, to assess structure of claws and empodia, not retained.

TERMINALIA ( Fig. 27A ). Gonocoxal synsclerite: ventral emargination U-shaped, with darkly pigmented margin; processes nearly straight, rounded apically, reinforced laterally; a narrowed portion anteriorly with only a few, mostly marginal setae; dorsal apodemes protrude beyond ventroanterior margin. Gonostylus: outside slightly convex, with numerous setae of various sizes; inside slightly concave, with much fewer setae of which 3‒4 are conspicuously long and bristle-like. Parameres fairly slender, crossing each other apically, with narrow transverse bridge subbasally. Aedeagal apodeme longer than gonocoxae, moderately sclerotized, slightly broadened and with large membranous cap apically; ducts of accessory glands evident (not illustrated).
