Diagnosis

Morphology

Males of C. gracilostylus sp. nov. differ from those of other Claspettomyia in a combination of several terminalia characters: the slender, nearly parallel-sided gonostylus lacks an apical bulge (↓ 5, Fig. 16B View Fig ), the short, robust parameres have small, barb-like processes dorsomedially (↓ 6), and the long, slender gonocoxal processes are strongly bent ventrolaterad (↓ 7). Larvae and females of the new species are unknown.

DNA barcode

The CO1 sequence(652bp) of the paratype specimen detailed below is available in BIN BOLD:AER0010. Search on BOLD’s BIN Database retrieved no further result for this BIN (accessed 13 Feb. 2023).

Differential diagnosis

The only other Claspettomyia whose gonostylus lacks an apical bulge is C. corniculata Mamaev, 1998 from the Far East of Russia. The terminalia illustration of the holotype specimen ( Mamaev 1998: fig. 4) suggests that the parameres are unusually short (even shorter than in C. gracilostylus sp. nov.) and bifid apically, and the unbent gonocoxal processes point posteriad. In Claspettomyia aff. kirghizica (cf. Jaschhof & Jaschhof 2013: 278, fig. 132a), a further superficially similar species, the gonostylus is slightly swollen apically and the parameres are thin and barbless.

Etymology

The specific epithet, a noun in apposition, highlights the slender gonostylus characteristic of this species.

Other characters

Male

BODY LENGTH. 1.7‒2.0 mm.

HEAD. Eye bridge dorsally 4‒5 ommatidia long. Antenna longer than body; scape and pedicel somewhat brighter than flagellum; flagellomeral nodes unpigmented; circumfila present on flagellomeres 1‒11; neck of fourth flagellomere 1.5 × as long as node ( Fig. 16C View Fig ). Palpus 1.4 × as long as head height.

WING. Longer than body. Length / width ratio 2.9.

TERMINALIA ( Fig. 16B View Fig ). Gonocoxal synsclerite: ventral emargination broadly U-shaped, with broad, darkly pigmented margin anteriorly; protuberances near gonostylar bases large, pointed, with sparse microtrichia of normal size and several fine setae. Gonostylus markedly bent subbasally, then straight; apex with plate-like tooth; outside with numerous setae of various lengths; inside more sparsely setose, including 2‒3 long subapical bristles.
