Noei, Javad & Rabieh, Mohammad Mahdi, 2019, New data on Nothrotrombidium, Southcottella and Eatoniana larvae (Acari: Trombellidae, Neothrombiidae, Erythraeidae) from Iran, Persian Journal of Acarology 8 (3), pp. 179-187 : 180-182

Eatoniana lorestanicus ( Saboori & Lachinani, 2003)

Diagnosis of larva [after Saboori and Lachinani (2003)]:

Solenidion on TFe I and Ge III present; two pairs of setae between coxae III; fn Ti 14-15-15; fn Ta 27-23-23; fPp: 0-B-B-BBN 2 -B3NωζCp.

Remarks

The recent re-examination of the holotype of E. lorestanicus by Prof. Alireza Saboori upon request showed that the number of normal setae on Ti II is 15 instead of 14. Also, the number of setae on leg Tarsi I–III and palp setal formula are as follows: fn Ta 27-23-23; fPp: 0-B-B-BBN 2 - B3NωζCp. Furthermore, Saboori and Lachinani (2003) did not mention the presence of " as " on ventral side of gnathosoma in their description and illustration. However, this seta is present and is short and smooth (5 long) ( Fig. 1 ). Table 1 shows the metric data of E. lorestanicus from Lorestan province, and South Khorasan province, Birjand (this study).

province [ Saboori and Lachinani (2003)].

This species was described from undetermined grasshoppers ( Orthoptera : Acrididae ) from Khorram Abad (Lorestan province), Iran. In this study, the species is collected as ectoparasite of Sphingonotus sp. ( Orthoptera : Acrididae : Oedipodinae ). The genus Sphingonotus is recorded as new host for Eatoniana larvae.

Saboori and Lachinani (2003) in their description of E. lorestanicus clearly stated "posterior claw a rod which may be spoon-like". Therefore, it cannot be a difference between E. lorestanicus and E. gonabadensis as written in identification key in Mąkol and Sevsay (2015) and corrected identification key is presented here.

Material examined

Seven specimens (ARS-20190321-1a– 1g) were collected as ectoparasites of Sphingonotus sp. ( Orthoptera : Acrididae : Oedipodinae ), IRAN: South Khorasan province, Birjand city, Chahkand village (32° 83' 66" N, 59° 15' 56" E, 1624 m a.s.l.), 18 June 2017, coll. J. Noei. The specimens are deposited in the Acarological Collection, Jalal Afshar Zoological Museum (JAZM), Department of Plant Protection, Faculty of Agriculture, University of Tehran, Karaj, Iran.
