Eatoniana lorestanicus ( Saboori & Lachinani, 2003 )


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.


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. 1View Figure 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.
