The Systematics of the Subfamily Ornithodorinae (Acarina: Argasidae). II. Identification of the Larvae of the Western Hemisphere and Descriptions of Three New Species1

Ticks parasitizing bats (Mammalia: Chiroptera) in the Caatinga Biome, Brazil

“…Additional reports included the collection of adults from caves in the Rondônia state within the Amazonian biome (LABRUNA et al, 2008). Although a detailed description of the larvae from both species has not been published, morphological characters of Antricola larvae presented by Cooley & Kohls (1944), and posteriorly by Kohls et al (1965), coincide with the general morphology of the larva found parasitizing P. parnelli in the present study. This host-parasite association is not unexpected since both Antricola and Pteronotus bats live in caves (ESTRADA-PEÑA et al, 2004;GUIMARÃES & FERREIRA, 2014;LABRUNA et al, 2011), and because Antricola larvae have been reported on Pteronotus bats in the Amazon biome (LABRUNA et al, 2011).…”

“…A total of 409 larvae belonging to Antricola, Nothoaspis and Ornithodoros genera were collected (Table 1). The single larva of Antricola was identified to genus level by the presence of three postcoxal setae (KOHLS et al, 1965) (Figure 1). One fully engorged larva of Nothoaspis amazoniensis Nava, Venzal & Labruna 2010 was identified by the following combination of characters: dorsal plate elongate and triangular; dorsum with 12-13 setae pairs (5-6 anterolateral, 3 central, and 4 posterolateral); venter with 10 pairs of setae; posteromedian setae absent; 3 pairs of sternal setae; 1 pair of post-coxal setae; 5 pairs of circumanal setae; 1 pair of ventral posteromarginal setae and basis capituli pentagonal, following Nava et al (2010) (Figure 2).…”

In addition, morphological identifications of 20 larvae were confirmed by molecular analyses.…”

“…Fourth-instar nymphs feed and then moult to Redrawn from Cooley and Kohls (1944). Redrawn from Kohls et al (1965). adults, which are always females.…”

Ornithodoros quilinensis sp. nov. (Acari, Argasidae), a new tick species from the Chacoan region in Argentina

“…All measurements are given in micrometres (µm), with the mean followed by the standard deviation and range in parentheses. In the descriptions, larval chaetotaxic terminology and measures followed Sonenshine et al (1962) and Kohls et al (1965), with the modifications proposed by Venzal et al (2008) and Labruna et al (2011). DNA was extracted from 2 larvae (one collected in 2010 and other in 2011) and processed using a polymerase chain reaction (PCR).…”
