The species is named after Fr. Juan Ignacio Molina, a famous Chilean naturalist and author of the first account of the natural history of Chile.</p><p>Remarks. The new species is similar to  Parasecia fundata (Brennan, 1969) but differs from it in a wider scutum (AW = 65–68 vs. 49–55, PW = 77–79 vs. 61–62, and SB = 32–35 vs. 22–24), a lesser number of idiosomal setae (VS = 12–13 vs. 17–22, and NDV = 34–35 vs. 39–44), and shorter PL setae (34–36 vs. 41–50).</p><p>The above comparison was based on the original description of  P. fundata (Brennan 1969) and our measurements of 2 specimens of this species collected in Costa Rica (ZIN collection Nos. 7069 and 7083). Collection data of this material were given by Stekolnikov et al. (2007). The new species moreover differs from Costa Rican specimens of  P. fundata in P-PL = 14–16 vs. 11–12 and in somewhat longer legs (Ip = 736–769 vs. 675 and TaIIIL = 63–65 vs. 52–56). However, these measurements were not reported for the type series of  P. fundata; therefore, their taxonomic significance is unclear.</p><p>Additional material of P. m o l i ni differs from the type series in a somewhat wider scutum (AW, PW), slightly shorter scutal and idiosomal setae (AM–V max), and in slightly shorter legs (pa, pp, Ip) (Table 3). Moreover, 2 of 3 specimens in this material (Nos. 8526 and 8527) have fPp = B/B/BBB vs. B/B/NNB in the type series. We consider these differences to be intraspecific.</p></div>	https://treatment.plazi.org/id/D41287FEFF84FF9B49FDFEF3FDA1FF78	Public Domain	No known copyright restrictions apply.

The species is named after Rodolfo Amando Philippi, a German and Chilean naturalist who made a valuable contribution to the knowledge of Chilean nature.</p><p>Remarks.  Paratrombicula philippii sp. nov. is the first known  Paratrombicula species having mastitarsala. However, this seta is ciliated in  P. philippii and therefore can be regarded as a typical tactile seta. By the presence of 2 genualae I,  P. philippii differs from all other  Paratrombicula (having only 1 genuala I) except  P. goff i Stekolnikov and González-Acuña, 2012, in which some part of examined specimens has 2 or 1/2 genualae I. Moreover, the new species is very close to  P. goffi by the measurable characters and differs from it in the presence of 7–9 setae in 2nd and 3rd rows of dorsal idiosomal setae vs. 6, larger number of idiosomal setae (DS = 37–38 vs. 28–32, VS = 30 vs. 20–26, NDV = 67–68 vs. 50–57), and in slightly shorter legs (Ip = 700–716 vs. 725–765).</p></div>	https://treatment.plazi.org/id/D41287FEFF9BFF9949FDFE1AFAEDFEB2	Public Domain	No known copyright restrictions apply.

Authors of the original description received the single specimen of this chigger from Fritz S. Lukoschus (Katholieke Universiteit Nijmegen, the Netherlands). The only collectional data they provided were as follows: “ Holotype from CHILE, Zelebor, ex  Octodon degus ” (Brennan &amp;  Goff 1978). Obviously, “Zelebor” is not a geographic term, but the collector’s name. Austrian naturalist Johann Zelebor participated in the Novara Expedition organized by Austrian Empire in 1857–1859 (Wurzbach 1890). This round-the-world mission stayed in the Chilean port Valparaíso from 17 April to 11 May 1859 (Scherzer 1863), where Zelebor could have obtained a specimen of degu. The range of this rodent species is characterized as “ Chile, west slope of the Andes between Vallenar and Curico” (Wilson &amp; Reeder 2005); this territory includes parts of Atacama, Coquimbo, Valparaíso, O’Higgins, and Maule Regions. Undoubtedly, the chigger mite was collected from this rodent in a museum by Lukoschus, more than a century later.</p></div>	https://treatment.plazi.org/id/D41287FEFF90FF9049FDFC5BFDB7F9DE	Public Domain	No known copyright restrictions apply.

Phyllotis osilae J.A. Allen,  Neotomys ebriosus Thomas ( Rodentia:  Cricetidae),  Lagidium peruanum Meyen ( Rodentia:  Chinchillidae). New host:  Neovison vison (Schreber) ( Carnivora:  Mustelidae).</p><p>Distribution. Peru. Recorded in Chile, Region of Magallanes and Antártica Chilena, Antártica Chilena Province, for the first time.</p><p>Remarks.  Trombicula macrochaeta Brennan and Jones, 1961 was described by 3 specimens (holotype and 2 paratypes) with broken sensilla. This defect resulted in erroneous identification of the tribe this species belongs to. Vercammen-Grandjean (1965a) placed it in the species group kallipygos within the genus  Guntherana Womersley and Heaslip, 1943, implying that this species should have expanded sensilla, as all members of Schoengastiini. Thorough examination of the description led us to the conclusion that this species undoubtedly belongs to the genus  Proschoengastia .</p></div>	https://treatment.plazi.org/id/D41287FEFF90FF9149FDF928FE2BFE59	Public Domain	No known copyright restrictions apply.

Thus, mastitarsala in  M. camanchaca is homologous to an unspecialized tactile seta in M.  jorgei, from which it differs in the lesser number of cilia and thin, whip-like distal part. Therefore,  M. camanchaca could be an intraspecific form of  M. jorgei; its status should be clarified using more extensive material and possibly molecular methods.</p><p>The whole sample of  Morelacarus collected in the Fray Jorge National Park, except 9 specimens of  M. jorgei and 3 specimens of  M. camanchaca, includes 6 unidentified specimens of poor quality ex  L. platei No. IV 136 (27).</p></div>	https://treatment.plazi.org/id/D41287FEFFA8FFAE49FDFB2EFA16FE7E	Public Domain	No known copyright restrictions apply.
