description: Tribus: Haplotropiidini Sergeev, 1995
Sergeev 1995: 38(2): 216. Type genus. Haplotropis Saussure, 1888.
Remarks. The taxonomic place of the genus Haplotropis Saussure is not clear. It was described in the present subfamily Thrinchinae (= Batrochotetriginae) (Saussure 1888: 125). Adelung (1910) gave it in the subfamily Pamphaginae (sensu Uvarov 1943). Uvarov (1943: 21) considered the Pamphagidae as a subfamily and divided it into 9 tribes. According to Uvarov (1943: 21) “future studies may show that it belongs to a tribe of its own, but for the time being it is best left in the Pamphagini, with which it agrees in the structure of vertex, while differing in this respect from the Thrinchini.” Sergeev (1995) erected the tribe “ Haplotropini ” after the only genus Haplotropis. According to Sergeev (1995) the genus Haplotropis is similar to Pamphagini in the structures of vertex and pronotum, but it is also similar to Thrinchini by the second anal vein of the hind wing is curved, thickened and well developed. Zhang et al. (2003: 220) included it to the subfamily Pamphaginae. Storozhenko & Paik (2011) acknowledged that in a previous paper dated 2007, they mistakenly included the genus Haplotropis in Thrinchinae and moved it in the subfamily Pamphaginae, due to the structure of fastigium of vertex, the arch-like median carina of pronotum, the presence of a few tubercles on the upper side of hind tibia; from Pamphaginae by the short apical valves of penis and the semi-bridge shaped epiphallus. I fully agree with Storozhenko & Paik (2011) that the most important character is the structure of male genitalia. The male genitalia of Haplotropis is much more in agreement with Thrinchinae (Figs. 1–2) rather than Pamphaginae (Figs. 3–5). As it is given in the subfamily key above, the tumida of cingulum and the dorsal valves of cingulum are present in Haplotropis (and Thrinchinae) which surrounds the apical valves of penis laterally (both absent in Pamphaginae), the rami is bordered by a narrow white band dorso-posteriorly in Haplotropis (and Thrinchinae) (Figs. 1–2). The apical valves of penis and aedeagus are variable in both subfamilies (Figs. 6–30 and 32–92). The presence of dorsal tubercles of the mid tibia is a character of the Thrinchinae as well. The semi-bridge shaped epiphallus is similar to the genera of Thrinchinae found in China and Mongolia such as Filchnerella, Eotmethis, Beybienkia, Mongolotmethis. Besides, the inner-ventral margin of hind femur without any spine or tubercle, completely smooth in Haplotropis as in all Thrinchinae (all Pamphaginae except the tribe Tropidauchenini and several specimens of N. African Pamphaginae, with distict small spines or tubercles), the very large arch of zygoma covered by a thin membrane (very narrow and small in Pamphaginae), the curved and thickened second anal vein are very important characters also fully agree with Thrinchinae. In addition, the distributional areas of Pamphaginae, Thrinchinae and Haplotropis and the biogeographical history of the both subfamilies given by La Greca (1999) support the separate state of Haplotropis from the subfamily Pamphaginae. It is a fact that the fastigium of vertex and pronotum are similar with the members of Pamphaginae, but these external characters probably represent a secondary adaptation to its home range, and are tribal characters distinguished from Thrinchini (see key to tribes of Thrinchinae). Because of the reasons given above it is concluded that the tribe Haplotropiidini with its only genus Haplotropis is here considered a member of the subfamily Thrinchinae.
