Specimens examined — 1♂ (UFMG AC 221059), 1 deutonymph ♀ (UFMG AC 221061) and 1 deutonymph ♂ (UFMG AC 221060) on Desmodus rotundus (1 ex.): Brazil, Minas Gerais, Rio Acima, carste/mata, PN Serra do Gandarela, -20.1105, - 43.6661 ° E, 27 Mar. 2020, collected by B. Gomes-Almeida et al. (COX1 sequence [voucher code]: OP964399 [UFMG AC 221059], OP964400[UFMG AC 221060] and OP964401[UFMG AC 221061]); 2 protonymphs (UFMG AC 220113–14) on Desmodus rotundus (1 ex.): Brazil, Minas Gerais, Montes Claros, Lapa Grande cave, PE da Lapa Grande, - 16.7067° S, - 43.9549° E, 13-14 Dec. 2021, collected by B. Gomes-Almeida et al. (COX1 sequence [voucher code]: OP964402 [UFMG AC 220114] and OP964403 [UFMG AC 220113]).

Barcode sequences — OP964399–403 ( Table 1).

Distribution — Brazil, Colombia, Costa Rica, Mexico, Panama, Paraguay, Peru, Trinidad, Venezuela ( Gettinger 2018 ; Beron 2020).

Hosts and records from Brazil — Artibeus planirostris : Mato Grosso do Sul ( Silva and Graciolli 2013 ; Silva et al. 2017); Desmodus rotundus (E. Geoffroy, 1810) : Distrito Federal ( Gettinger and Gribel 1989), Mato Grosso do Sul ( Silva and Graciolli 2013 ; Silva et al. 2017), Minas Gerais (new report in present study), Rio de Janeiro ( Confalonieri 1976 ; Almeida et al. 2011), São Paulo ( Confalonieri 1976); Myotis nigricans : Mato Grosso do Sul ( Silva and Graciolli 2013); Sturnira lilium : Mato Grosso do Sul ( Silva and Graciolli 2013 ; Silva et al. 2017).

Differential diagnosis — Female: distance between first and second pairs of dorsal proteronotal setae less than or equal to distance between second and third pairs; six opistonothal setae short to very short (first pair just posterior to coxa IV largest). Sternal plate subpentagonal in shape, with narrow anterior border, and an acute small and triangular tip (homomorphic), or with sternal plate with subpentagonal shape gradually distorted to a spade-shaped outline with a broad arrow head pointed tip (maximum heteromorphic form); proximal anterodorsal seta of tibia II large ( Morales-Malacara et al. 2018). Male: narrow longitudinal and cross-shaped unsclerotized crack in the center of dorsal plate (Morales-Malacara 2001; Morales-Malacara et al. 2018) ( Figure 9B ); intercoxa IV area with nine pairs of setae, plus one pair of adanal setae: first pair small to medium sized and situated posterior to sternogenital plate ( Herrin and Tipton 1975) with a unique reticulated sclerotized pattern over most of plate ( Figure 9C ) (Morales-Malacara 2001; Morales-Malacara et al. 2018).

Nymphs ( Figure 10A–N ): similar to males with regard to above features, except by ontogenetic differences ( Deunff et al. 2011). Deutonymph female has 13 pairs setae on intercoxal IV area, including adanal pair, and seven pairs of hysteronotal setae (one pair poststigmal setae and six pairs opisthosomal setae) and plus one unpaired seta on caudal dorsum. Deutonymph male has 10 pairs setae on intercoxal IV area, including adanal pair, and five pairs hysteronotal setae (one pair poststigmal setae and four pair opisthosomal setae) and plus one unpaired seta on caudal dorsum (similar to adult male). Protonymph has only two pairs hysteronotal setae (one pair poststigmal setae and one pair opisthosomal setae) and plus one unpaired seta on caudal dorsum.

Remarks — P. herrerai is reported for the first time from Minas Gerais. This species is monoxenous associated with the vampire bat, D. rotundus . Morphological characters of –

examined specimens match those of the original description and re-descriptions ( Machado-Allison 1965a ; Furman 1966 ; Herrin and Tipton 1975 ; Morales-Malacara et al. 2018), except by four pairs of dorsal opisthosomal setae on male deutonymph, instead of three pairs.

In our bGMYC species delimitation analyses ( Figure 2 ), both Periglischrus herrerai haplotypes (haplotypes 36 and 37) out of five sequences recovered as a single putative species with pp.>95%.
