Differential diagnosis. Habitus as in Figs. 1 and 6. Chilotrogus panotrogoides is extremely similar to Ch. matejicecki new species and can only be differentiated by morphology of male genitalia. See treatment of the latter for a discussion of diagnostic characters.
Distribution. Broadly distributed in the Kerman province, both on the plateau and on mountains, between 1800 and 2900 m a.s.l., possibly parapatric with respect to its close relative Ch. matejiceki new species, and at least partially sympatric with Ch. schoolmeestersi new species. A single outside record is known from lowland close to the coast in Hormozgan province (Fig. 47).
Remarks. Reitter (1905) described the genus Chilotrogus to accommodate his new species Ch. panotrogoides. In the primary description, he indicates that he describes it on a unique specimen captured by A. Matthiessen who kindly offered it to him: “ Zentral-Persien (Kerman.) Von Herrn A. Matthiessen (Kivennapa, Finnland) 1 ♂ entdeckt und mir freundlichst überlassen ”. [= “Central Persia (Kerman.) From Mr. A. Matthiessen (Kivennapa, Finland), one male discovered and kindly donated to me”]. A corresponding specimen was found at HNHM, where Reitter collection is housed (Fig. 6). It bears a red bordered label that identifies it as “Monotypus”, which however has been placed afterwards under the specimen following a sometimes unwarranted curatorial work on Reitter’s type specimens housed at HNHM (Reitter never added any label mentioning holotype or paratype to his specimens, see also Miessen 2019). Anyway, based on the first three labels, which are handwritten by Reitter (a sample of a label by Reitter can be found in Horn & Kahle (1935 –1937, plate 10)), we do confirm this specimen to be the true holotype, and we add a new red label: “ Chilotrogus panotrogoides Reitter, 1905 holotypus ♂, id. Miessen, Uliana & Keith, 2019”.
Surprisingly, we found another specimen in the collection of Rudolf Petovitz (MHNG), apparently collected together with the holotype and labelled as paratype (labels in Fig. 8). Petrovitz also labelled a female captured by himself as allotype (labels in Fig. 7), declared as such and described in Petrovitz (1980: 619). Because Ch. panotrogoides was described according to holotype only, both these specimens deposited in MNHG should be removed from the type series.
Due to the similarity of this species to Ch. matejiceki new species, we thought useful to revise a part of the typical series (including holotype) of Articephala phasmella, which allows us to confirm the synonymy with Ch. panotrogoides established by Keith (2006).
