Fang, Yan, Zhang, Haichun & Wang, Bo, 2009, A new species of Aboilus (Insecta, Orthoptera, Prophalangopsidae) from the Middle Jurassic of Daohugou, Inner Mongolia, China, Zootaxa 2249, pp. 63-68 : 64

Genus Aboilus Martynov, 1925

Type species. Aboilus fasciatus Martynov 1925 ; by original designation.

Type horizon and locality. Middle–Upper Jurassic, Galkino village, East Karatau, Kazakhstan.

Revised diagnosis. Male tegmen oblong or broadly oval, precostal area ordinary-sized or narrow; C slightly arched, ending in anterior margin before the middle length of tegmen, proximal branches of Sc arched upwards, ending in stem C; RS diverging from R slightly before the middle length of tegmen; both RA and RS giving not less than 4 branches; origin of MA2 much closer to fusion point of MP+CuA1 than to origin of RS; “handle vein” nearly straight, ending in fusion point of MP and CuA1 or branch of MP+CuA1, no crossveins between “handle vein” and CuA1; “oblique veins” (crossveins between CuA2 and CuP) almost straight and sub-parallel to each other.

Included species. At least 19 species: type species Aboilus fasciatus , A. columnatus , A. femineus , A. zebra and A. chinensis sp. nov. based on male tegmina; A. abbreviatis , A. amplus , A. aulietus , A. cornutus , A. dilutus , A. jiyuanensis , A. krassilovi , A. lamina , A. longitudinalis , A. pullus , A. stratosus , A. tigirs , A. transverslis and A. tuzigouensis based on female tegmina.

Remarks. Up to now, 11 genera were assigned to Aboilinae Martynov, 1925 based on male tegmina including Aboilus Martynov, 1925 , Apsataboilus Gorochov, 1990 , Bacharaboilus Gorochov, 1988 , Circulaboilus Li et al. 2007 , Flexaboilus Li et al. 2007 , Novaboilus Li et al. 2007 , Prophalangopseides Sharov, 1968 , Sigmaboilus Fang et al. 2007 , Sunoprophalangopsis Hong, 1982 , Tettaboilus Gorochov, 1988 and Utanaboilus Gorochov, 1990 . Some other genera which were established on female tegmina possibly belong within the same subfamily, namely Archaeohagla Lin, 1965 , Angustaboilus Li et al. 2007 , Baissaboilus Gorochov, 1996 , Furcaboilus Li et al. 2007 , Karatailus Gorochov, 1996 , Mesohagla Zhang, 1996 , Nipponohagla Fujiyama, 1978 , Pseudohagla Sharov, 1962 , Pycnophlebia Deichmuller, 1886 , Shangxiania Zhang, 1993 and Sinohagla Lin, 1965 .

Aboilus is similar to Prophalangopseides , but differs in branches of Sc simple; RS arising slightly before the middle length of tegmen; the origin of MA2 much closer to the tegminal base and crossveins not forming “fan” veins between CuA and CuP. Although similar to Protaboilus in stem C, the precostal area and costal area, it is different from the latter in crossveins between CuA and CuP straight or weakly arched. Differs from Sigmaboilus in the precostal area narrow, stem C comparatively short, and MP and CuA1 not united for an appreciable distance.
