Type material examined. Henricohahnia wangi Ren, 2001 . Holotype: ♀, “<Yunnan Xishuangbanna Mengzhe> [ch] \ 1200 <m> [ch] \ < Chinese Academy of Sciences > [ch]” [with horizontal line between lines #2 and #3], “ 1958. VII. 8 [hw] \ <collector: Wang Shu Yong> [ch]”, “ Henricohahnia [hw] \ wangi Ren , sp. [hw] \ nov. [hw] \ HOLO- TYPE [pr] 2000.V. [hw]” [red, with pr black frame]; pinned, right distiflagellum missing ( NKUM) ( Figs. 7–14 ).

Diagnosis. Differs from other species of Henricohahnia Breddin, 1900 , in the presence of conspicuously large and robust, almost cylindrical tubercles on the anterior lobe of the pronotum (with a particularly large pair posteriorly), on the head ventrolaterally ( Figs. 10–11 ), and on the scape subapically ( Fig. 12 ); these tubercles are distinctly smaller in other congeners. In respect of the above characters it is fairly similar to H. montana (Distant, 1903) , known from northeastern India (type material examined); due to the lack of males it is tentatively maintained as a distinct species.

Distribution. CHINA: Yunnan!

Discussion. Henricohahnia wangi was described based on a single female (the holotype) from Xishuangbanna Dai Autonomous Prefecture, Yunnan, China. This specimen is deposited in NKUM and it was reexamined during the present study ( Figs. 7–14 ). Henricohahnia obscara was described based on a female holotype and two female paratypes, also from Xishuangbanna. According to the original description the holotype was deposited in IZAS, but our request to this institution to study their reduviid types was declined; the satisfactory original descriptions and illustrations, however, enable an identification of this species.

The specific epithet of H. obscara was spelled as obscara in pp. 155, 160, 163 and 164, but obseura in p. 156 of the paper containing the original description. The authors ( Cai et al. 2003: 162) stated that “[t]he species [is] named for its dull colour”, therefore apparently they intended to create the name obscura from the Latin adjective obscurus, - a, - um, but this spelling does not appear in the paper, therefore the spelling obscara is selected here as the correct original spelling acting as First Reviser ( ICZN 1999, Art. 32.2.1), and obseura is considered as a typographic error, hence an incorrect original spelling. The subsequent usage of the specific epithet obscura ( Zhao et al. 2014: 368) must be considered as an incorrect subsequent spelling.

Cai et al. (2003) did not mention H. wangi in their review of Henricohahnia from China, suggesting that they had overlooked this species. Subsequentely Zhao et al. (2014: 368) speculated that H. obscara (misspelled as obscura ) differs from H. wangi by the “apical spine of lateral pronotal angle pointed lateroposteriorly, but not upturned” (“distinctly upturned and pointed laterally” in H. wangi ), and “head laterally ventrally [on] each [side] with 3 long cylindrical tubercles” (“with more than 3 large tubercles” in H. wangi ). These diagnostic characters were apparently based on the illustrations of Ren (2001: 1, figs. 2 and 3); the figures in concern, however, are inaccurate, especially with respect to the ventral armature of the head. The head of the holotype is shown in Figs. 10 and 11 ; these photographs were taken after relaxing the specimen and pulling the forelegs away, thus exposing both lateral sides of the head. The ventrolateral side of the head of the holotype is provided with four tubercles on the left side, but only three tubercles on the right side (the tubercle marked with arrow in Fig. 10 has no counterpart on the right side); the right side therefore perfectly matches the condition figured by Cai et al. (2003: 164, fig. 36) for H. obscara , rendering this diagnostic character suggested by Zhao et al. (2014) for differentiating the two species invalid. Similar to the ventrolateral tubercles on the head, the humeral processes also show considerable variability, with clear asymmetry between the left and the right side; the condition found in the holotype of H. wangi , particularly its left-hand side, is not different from the condition figured for H. obscara by Cai et al. (2003: 163–164, figs. 35, 36 and 41). Other diagnostic characters provided for H. obscara by Cai et al. (2003), e.g. the shape and arrangement of the tubercles on the scape or the shape of the female terminalia show a very close match with the condition found in the holotype of H. wangi ( Figs. 12, 13 ; cf. Cai et al. 2003: 164, figs. 37–39 and 43, respectively). It can be concluded that currently no difference of potential specific importance can be demonstrated between H. wangi and H. obscara , therefore the subjective synonymy of the two species is hereby proposed.
