gen. nov.

Phaenospila van Achterberg & Yao , gen. nov.

( Figs 2–4 View FIGURE 2 View FIGURE 3 View FIGURE 4 )

Type species: Phaenospila signator Yao , sp. nov. Gender: feminine.

Etymology. From a combination of two generic names ( Phaenocarpa and Cratospila ) because it belongs to the Phaenocarpa group of genera and shares with Cratospila the very elongate antennomeres ( AS). However, in the latter genus the first flagellomere is longest instead of the second.

Diagnosis. Antenna with white band, AS 4 strongly elongate and 1.8–2.7 × as long as AS 3; clypeus semicircular and ventrally obtuse; precoxal sulcus complete and crenulate; postpectal carina present ventrally and more or less lamelliform; vein r issued distinctly behind middle of pterostigma; marginal cell of fore wing reaching apex of wing (rarely remaining removed from apex) and vein 1-R1 1.4–1.9 × as long as pterostigma ( Fig. 2B View FIGURE 2 , 3B View FIGURE 3 , 4F View FIGURE 4 ); veins 1-M and m-cu of fore wing subparallel ( Fig. 2B View FIGURE 2 , 3B View FIGURE 3 , 4F View FIGURE 4 ); vein 1-SR+M of fore wing evenly curved basally; vein 1r-m of hind wing gradually merging into vein 1-M; vein m-cu of hind wing far antefurcal and unsclerotised basally; vein M+CU of hind wing 0.7–1.0 × as long as vein 1-M; setose part of 0.4–0.5 × as long as fore wing and 1.1–1.6 × as long as hind tibia, ovipositor sheath setae long and moderately dense ( Figs 2I View FIGURE 2 , 3I View FIGURE 3 , 4H View FIGURE 4 ).

Distribution. Oriental ( Thailand).

Biology. Unknown.

Notes. The genus Phaenospila van Achterberg & Yao , gen. nov. runs in the key to the genera and subgenera of the Alysiini by Zhu et al. (2017) to Alysiasta . However, the new genus can be separated from Alysiasta Wharton as follows:

1 Postpectal carina present ventrally, lamelliform ( Figs 2C View FIGURE 2 , 3C View FIGURE 3 ); vein m-cu of hind wing largely unsclerotised ( Figs 2B View FIGURE 2 , 3B View FIGURE 3 , 4F View FIGURE 4 ); vein 1-R1 1.5–1.6 x as long as pterostigma ( Figs 2B View FIGURE 2 , 3B View FIGURE 3 , 4F View FIGURE 4 ); antenna with white band ( Figs 2A View FIGURE 2 , 3A View FIGURE 3 , 4A View FIGURE 4 ); fourth antennomeres very elongate, 1.8–2.7 x longer than third segment ( Figs 2F View FIGURE 2 , 3D View FIGURE 3 , 4E View FIGURE 4 ); wing membrane subhyaline; metanotum not or slightly protruding dorsally ( Figs 2F View FIGURE 2 , 3G View FIGURE 3 , 4E View FIGURE 4 ); veins 1-M and m-cu of fore wing subparallel ( Figs 2B View FIGURE 2 , 3B View FIGURE 3 , 4F View FIGURE 4 ); biology unknown; Old World.......................................................... Phaenospila van Achterberg & Yao , gen. nov.

- Postpectal carina absent ventrally; vein m-cu of hind wing distinctly sclerotised basally (Fig. 20 Wharton 1980; Fig. 1C View FIGURE 1 Dix 2010); vein 1-R1 1.1–1.2 x as long as pterostigma (Figs 19, 25 Wharton 1980; Fig. 1B View FIGURE 1 Dix 2010); antenna without white band; fourth antennomeres less elongate, 1.3–2.0 x longer than third segment (Figs 5, 6 Wharton 1980); wing membrane darkened; metanotum more or less acutely protruding dorsally; veins 1-M and m-cu of fore wing strongly covering posteriorly (Figs 19, 25 Wharton 1980; Fig. 1B View FIGURE 1 Dix 2010); parasitoids of Sarcophagidae View in CoL ; New World, East Palaearctic?.. Alysiasta Wharton, 1980 View in CoL

Notes (by CvA). The genus Alysiasta Wharton, 1980 View in CoL (as treated in this paper has a New World distribution, with the possibly exception of the East Palaearctic species A. udaegae Belokobylskij, 1998 View in CoL . This species may belong to Alysiasta View in CoL despite a fore wing marginal cell that is longer than normal for Alysiasta View in CoL , but vein 1-R1 of the fore wing is 1.1 times longer than the pterostigma (which is similar to New World Alysiasta View in CoL ). The oblique vein m-cu of fore wing and the far antefurcal vein m-cu of hind wing allow for retaining this species in Alysiasta View in CoL , but the partly pale antenna and subhyaline wing membrane indicate that it might not belong to this genus. Fischer (2006) included the Oriental Phaenocarpa abbreviata Bhat, 1979 and P. sikkimensis Bhat, 1979 in Alysiasta View in CoL but the first species belongs to a yet undescribed genus and the second to Idiasta Foerster, 1863 View in CoL (comb. nov.) because of the comparatively long hind wing vein M+CU. Alysiasta triangulum Fischer, 2006 View in CoL belongs to a newly described genus Anamalysia van Achterberg, 2022. Two Afrotropical species are included by Fischer (2006): A. multicrenis Fischer, 2006 View in CoL has a long vein 1r-m and strongly widened marginal cell of fore wing indicating that it does not belong in Alysiasta View in CoL . Most likely is an aberrant species of Heratemis Walker, 1860 View in CoL (comb. nov.). The second species, A. levigata Fischer, 2006 View in CoL is insufficiently described to place the species in a genus, but the illustrated fore wing (e.g. marginal cell reaching tip of wing and vein m-cu angled with vein 2-CU1) indicates that it does not belong to Alysiasta View in CoL . The description does not indicate why it should be included in Alysiasta View in CoL and the description does not supply arguments against inclusion in Idiasta Foerster, 1863 View in CoL , therefore, it is treated provisionally as belonging to Idiasta View in CoL .
