Aphelinoidea (Aphelinoidea) subexserta Nowicki, 1940: 659 View in CoL (illustration), 660–661. Type locality:

Szépvölgy­ District­ of­ Budapest,­ Hungary­ (“by­ sweeping­ grass­ in­ the­ wood­ and­ in­ the­

field”).

Aphelinoidea subexserta Nowicki View in CoL : Doutt & Viggiani 1968: 530 (list); Fursov 2007: 969 (key, dis-

tribution [as A. subexerta , misspelling]); Viggiani 2011: 104 (list [as A. subexerta , mis-

spelling]); Hu & Lin 2005: 153 (compared to A. shawanica ) [as A. subexserta Novicky ].

Aphelinoidea (Aphelinoidea) subexserta Nowicki View in CoL : Trjapitzin 1995: 302 (listed in the anatolica View in CoL species

group of Aphelinoidea View in CoL s.str.), 305 (key), 307–308 (compared with A. melanosoma View in CoL and A.

turanica).

Aphelinoidea monocroma [Nowicki]: Viggiani 2011: 104 (list). Nomen nudum.

Diagnosis: Aphelinoidea subexserta belongs to the plutella species group of A. ( Aphelinoidea ) as it has a hyaline, sparsely setose path on the fore wing disc beyond the­venation­(Figs­80,­84,­86).­It­is­very­similar­to,­and­quite­likely­conspecific­with,­ A. shawanica in having a relatively long ovipositor (1.8–2.1× length of metatibia), as discussed in the diagnosis of the latter above.

Redescription: Female (holotype). Head of ( Fig. 77) lighter than rest of body (except gena dark brown); mesosoma notably lighter than gaster and apparently brown­(Fig.­79);­gaster­ dark­ brown;­antenna­ mostly­ brown­ except­ first­ segmentof clava a little lighter; legs brown to dark brown except apices of tibiae light brown.

Antenna ( Fig. 78) with scape minus radicle 3.1× as long as wide; pedicel 2.2× as­long­as­wide;­first­anellus­much­larger­than­second,­the­latter­partially­imbedded­into­first­claval­segment;­clava­3.1×­as­long­as­wide,­2.1×­length­of­pedicel;­apicalsegment of clava 3.0× length of basal segment, the latter incompletely, obliquely divided in middle on its inner side; basal segment of clava with 1 mps, apical segment with several mps.

Mesoscutum and scutellum with faint cell-like sculpture and each with mediolongitudinal groove ( Fig. 79). Fore wing ( Fig. 80) disc almost hyaline beyond

venation and slightly infuscate behind venation (more so just behind stigmal vein as small darker spot), with distinct hyaline, sparsely setose (most setae very short except for a few distinct setal lines) path across wing just beyond venation, more or less uniformly setose in apical 0.5 of wing (beyond the hyaline area) except for a few distinct setal lines.

Ovipositor relatively long, 2.0× length of metatibia, occupying about 0.85× length of gaster ( Fig. 79) and exserted slightly beyond its apex. Hypopygium extending to about 0.6× length of gaster.

Measurements of the remounted holotype (µm). Metasoma, 400; ovipositor, 354. Antenna, radicle, 18; rest of scape, 83; pedicel, 63; clava (given as lengths of basal/apical segments), 33/98. Fore wing length, 603. Metatibia, 176.

Variation. Paratype “a”:body length 713µm.Non-type,slide-mounted specimens of Nowicki: body length 683–818 µm; mesosoma brown to dark brown; antenna with scape minus radicle 2.7–3.6× as long as wide, clava 2.5–3.0× as long as wide and 2.1–2.3× length of pedicel, apical segment of clava 2.3–2.7× length of basal segment; fore wing 2.0–2.1× as long as wide, longest marginal seta about 0.07× greatest width of wing; hind wing ( Fig. 81) 12.7× as long as wide, disc almost hyaline (except slightly infumate behind venation) and with 3 rows of setae, longest marginal seta 1.5× greatest width of wing; ovipositor 1.8–2.1× length of metatibia (usually 1.9–2.0×), sometimes occupying almost entire length of gaster.

Description: Male (previously unknown; non-type specimens of Nowicki from Europe). Body length 713–800 µm (slide-mounted specimens). Similar to female in color. Antenna ( Fig. 82) with scape minus radicle 3.3× as long as wide; clava 2.0–2.6× as long as wide. Fore wing ( Fig. 84) about 2.1× as long as wide. Genitalia ( Fig. 83) length 124–130 µm, aedeagal apodemes present.

Type material examined: ­ Holotype­ ♀ ­ [ DEZA],­ remounted­ at­ UCRC­ in­ December­ 2011 ­ from­ adried (cracked), darkened water-soluble mountant ( Fig. 75) in the original Nowicki-style micro-slide on a pin ( Fig. 74) ( Viggiani 2011) onto a normal slide in Canada balsam ( Fig. 76) and labeled as follows: (1) [data label glued onto the underside of the original micro-slide] “Budapest [in pencil] Szépvölgy­10.VII.37­[in­blue­ink]­ Aph. monochroma [faintly in pencil]”, (2) [added after remounting] “Remounted from dry liquid Faure at UCR/ERM by V.V. Berezovskiy 2011 in Canada balsam”, (3) [added after remounting] “ Aphelinoidea subexserta Nowicki ,­ 1940­ HOLOTYPE­ ♀ ­ Det.­ by­ S. V. Triapitsyn 2011”. The holotype, whose collecting date was indicated by Nowicki (1940) as 11.vii.1937, is in poor condition, with the following remaining parts now mounted under separate coverslips: the head with one antenna (lacking the clava) and radicle of the other antenna attached to it, the other antenna without a radicle, the body with most leg segments detached and fragmented, and the incomplete fore wings .

Paratype:­Viggiani­(2011)­mentioned­seven­specimens­of­this­species­in­Ś.­Nowicki’s­collectionat DEZA (misspelled as “ subexerta ”) and also six specimens of “ A. monocroma ” (nomen nudum, misspelling of Nowicki’s manuscript name “ A. monochroma ” which he changed to A. subexserta in­its­original­description).­Examined­was­paratype­“a”­[1♀,­ DEZA]­(Figs­85–87)­of­ A. subexserta (Nowicki 1940) from Hungary: Nagy Hortobágy in the Hungarian Puszta (Hortobágy National Park, W of Debrecen, Hajdú-Bihar County), similarly remounted at UCRC into Canada balsam from the original darkened, completely dried micro-slide labeled (the data label glued onto its underside): (1) “N. Hortobágy 13.VII.37 Aphe-a female [an illegible name followed by “var.” and another illegible name, written very faintly in pencil] n. sp.”, (2) [originally on the same pin with some other micro-slides of A. subexserta including the holotype and several non-type specimens, and obviously initially intended to be the holotype of this species under a different manuscript name] “Det. S Novickij [printed]­ ♀ ­ Aphelinoidea monochroma n. sp. v. pusztae [i.e., of the undescribed variety of the Puszta] n. sp. HoloType!” [in India ink] ( Fig. 85). This paratype of A. subexserta is now in fair condition but lacking most of both antennae (except for the scapes), both hind wings, some leg segments, and also the very tip of the ovipositor which is broken off; its fore wing ( Fig. 86) and body ( Fig. 87) are illustrated here to facilitate recognition of this species.
