Abstract

Teneriffia hajiqanbari n. sp. is described based on female, male, and deutonymph specimens collected in mangrove forests in Qeshm Island, in the eastern part of the Persian Gulf, southern Iran. This new species can be distinguished by following characters: gnathosoma without “clasps” ventrally; palpal oncophysis absent; venter with 17–20 pairs of setae; genital plates with seven pairs of setae (female); dorsal body setae minutely barbed; opisthosomal setae d1, e1 and f1 long and reaching or surpassing the base of next seta; solenidotaxy of tarsi I–IV: 3-3-0-1. Additionally, an identification key to known species of Teneriffia is updated.


Introduction

Members of the family Teneriffiidae are red, yellow, or brownish long-legged predators that are fast-moving and medium-sized mites (Walter et al. 2009; Luxton 1993). Teneriffiids occupy many different habitats, ranging from the sea level to altitudes about 2,000 m in terrestrial and marine ecosystems, including intertidal sandbanks, undersides of rocks, caves, arid desert, plants, soil, and forest litter (Walter et al. 2009; Khanjani et al. 2011; Ueckermann and Durucan 2020).

The Teneriffiidae comprises about 27 species in the nine genera: Austroteneriffia Womersley, 1935 (9 or 10 species); Heteroteneriffia Hirst, 1925 (3 species); Himalteneriffia Schmölzer, 2002 (1 species); Mesoteneriffia Irk, 1939 (2 species); Mesoteneriffiola Schmölzer, 1956 (1 species); Neoteneriffiola Hirst, 1924 (5 species); Parateneriffia Thor, 1911 (1 species); Sinoteneriffia Yin et al., 1994 (1 species) and Teneriffia Thor, 1911 (4 species) (Schmölzer 2002; Ueckermann and Durucan 2020; Zmudzinski et al., 2021). The genus Teneriffia was erected by Thor (1911), with Teneriffia quadripapillata Thor, 1911, as the type species collected from Spain (Canary Islands). Until the present study, four species of this genus have been described from the world. The genus Teneriffia can be distinguished from other genera of the family by having a simultaneously prodorsal shield, coxae I–IV at least with five setae each and strongly bipectinated claws on tarsi I–II (Schmölzer 2002; Ueckermann and Durucan 2020).

During studies on mite fauna of the mangrove forests of southern Hormozgan province, a new species of Teneriffia was discovered. Herein, we describe T. hajiqanbari n. sp., the first species of Teneriffia recorded from Iran. Also, an updated key to the world species of Teneriffia is presented.

Material and methods

Mites were extracted from littoral and soil samples collected in mangrove forests in southern Iran using Berlese-Tullgren funnels, cleared in Nesbitt's fluid and mounted in Hoyer's medium. Morphological observations, measurements and illustrations were made using a compound microscope equipped with differential interference contrast and phase contrast optical systems and a drawing tube (Olympus BX51). Initial pencil line drawings were then scanned and cleaned using Adobe Illustrator CS6. Additional images were prepared using the automated Z-stacking feature of the Nikon NIS Elements package on a Nikon Eclipse 90i (Melville, NY) compound microscope with a PC controlled Ds-5M-U1 digital camera at the Acarology Laboratory of the Ohio State University (OSAL). Measurements are in micrometers (μm). The body length and width of the specimens were measured from the suture between the gnathosoma and idiosoma to the posterior margin of the idiosoma and at its broadest level, respectively. The length of the gnathosoma was taken from the base to the tip of the subcapitulum. The leg lengths were measured from the ventral insertion of the coxae to the base of the pretarsi. Measurements of the paratypes are given in brackets following that of the holotype. Terminology generally follows that of Ueckermann and Durucan (2020) and Kethley (1990).

Remarks

At first glance, the new species closely resembles Teneriffia sebahatae Ucekerman & Durucan, 2020 in having gnathosoma without ''clasps'' ventrally, palpal oncophysis absent, and solenidotaxy on legs. However, T. hajiqanbari n. sp. can be easily distinguished from T. sebahatae by the following characters: (1) ventral idiosoma with 17–20 pairs of setae (vs. 23 pairs in T. sebahatae); (2) genital plates (female) with seven pairs of setae (vs. six pairs in T. sebahatae); and (3) opisthosomal setae d1 , e1 and f1 long and reaching or surpassing the base of next seta (vs. short and not reaching in T. sebahatae). Also, length of setae ve 114 (106–116), d1 111 (92–104), e1 101 (94–109), f1 126 (114–129) and h1 126 (106–124) instead of length of setae ve, d1 , e1 , f1 and h1 = 58–78 in T. sebahatae.

Etymology

The species is named in honor of Dr. Hamidreza Hajiqanbar (17 August 1973–18 Oct 2021), a distinguished and well-known Iranian Acarologist who has made outstanding contributions to Acarology, especially Heterostigmatina.
