Diagnosis

Morphology

Cassidoides riparius sp. nov. is one of the smallest species known of the genus. The male is barely 1.3 mm long and its terminalia are of tiny dimensions ( Fig. 15D View Fig ). A terminalia structure peculiar to this species relates to the gonocoxal processes, which each consist of a broad, presumably flattened portion basally that transitions into a thick, tusk-shaped portion apically (↓ 4, Fig. 15D View Fig ). Larvae and females of the new species are unknown.

DNA barcode

The CO1 sequence (653bp) of the holotype specimen is available in BIN BOLD:AER0232. Search on BOLD’s BIN Database retrieved no further result for this BIN (accessed 26 Aug. 2023).

Etymology

The Latin adjective ‘ riparius ’ means ‘living on the riverbank’, an allusion to the habitat in which the holotype specimen was collected.

Male

HEAD. Eye bridge dorsally 1‒2 ommatidia long. Antenna shorter than body; scape and pedicel brighter than flagellum; 12 flagellomeres; apical flagellomere long, composed of two nodes; circumfila present on all flagellomeres, irregularly sinuous; neck of fourth flagellomere 1.1× as long as node ( Fig. 15C View Fig ). Palpus 4-segmented, nearly as long as head height.

WING. Slightly longer than body. Length /width ratio 2.7. M 4 extremely faint, CuA ending well before wing margin.

LEGS. Acropods, to assess structure of claws and empodia, not retained.

TERMINALIA ( Fig. 15D View Fig ). Gonocoxal synsclerite broader than long, with dense setae of very different lengths ventrally; ventral emargination faintly contoured, apparently U-shaped. Gonostylus compact, 1.5 × as long as thick; outside with numerous setae of various lengths; inside slightly excavated, sparsely setose incl. 2‒3 long subapical bristles; pectinate claw broad, slightly undulated ( Fig. 15E View Fig ). Aedeagal apodeme about as long as gonocoxae, its sclerotized portion narrowed apically and covered by membranous cap. Tegmen: shaped like inverted V, apex bent slightly dorsad, blunt with small indentation.
