Allothrombium monosolenidion Kamran and Alatawi, 2020: 736 , syn. nov. [L].
Diagnosis: Adult and Deutonymph. See Mąkol (2005).
Larva (after Kamran and Alatawi, 2020). Colour in live specimens yellowish orange. Hypostomal setae ( bs) calyx, with 4-7 finger-like digitations. fD = 24, fV = 6, fnCx 2-2-1. Genua II and III each with one solenidion. Pretarsi I and II with two claws and a claw-like empodium. Pretarsus III with anterior claw and a claw-like empodium. Posterior claw on pretarsus III absent.
Description: Adult ( Fig. 1 View Figure 1 ) and Deutonymph, See Mąkol (2005).
Larva ( Figs 2 View Figure 2 , 3 View Figure 3 ), See Kamran and Alatawi (2020). Male. Not collected and reared in this study. Deutonymph. Not collected and reared in this study.
Distribution: Hungary, Italy [?], Poland and The Netherlands ( Mąkol, 2005, 2007; Mąkol and Wohltmann, 2012). New record from Türkiye (pesent work).
Laboratory observations and biology: The one female, collected on May 2019, laid 40 yellowish-orange eggs in a cluster two days after capture. A total of 35 larvae hatched within 21-22 days after oviposition. Another female, collected on April 2023, laid 35 yellowish-orange eggs in a cluster seventeen days after capture. A total of 32 larvae hatched within 21-22 days after oviposition.
Ten unfed members of the latter group of larvae were exposed to different host candidates (Diptera, Lepidoptera, Orthoptera and Homoptera). Of these, however, only representatives of Aphis ( Hemiptera : Sternorrhyncha: Aphididae ) were parasitized by the larvae of A. incarnatum . Remarks: The crista metopica and the dorsal seta structures of the females, from which the larvae were obtained, are compatible with the species A. incarnatum ( Figs 1 A, B View Figure 1 ). These females have three pairs of papillae in their genital openings ( Fig. 1 C View Figure 1 ). In the morphometric comparison of Polish and Turkish females of A. incarnatum (see Table 1), the differences in the length of the following characters are striking; CML (94.8-138.2 vs. 195-270) and tibia I (94.8-142.2 vs. 180-190). However, the structure and length of the pDS setae of both groups of specimens are compatible. In our opinion, the reason for these measurement differences is that the range of variation is larger for some character lengths. The fact that Oudemans (1916) gave the length of tarsus I of the female specimen of this species as 370 (op. cit., p. 42) supports our opinion. Of all the larval species described in the genus Allothrombium , only A. monosolenidion is characterized by having one solenidion on genua II and III (other species have two solenidia) ( Kamran and Alatawi, 2020). The larva of A. incarnatum ( Fig. 2 View Figure 2 ) also has one solenidion on genua II and III ( Fig. 3 View Figure 3 ). Morphologically, there are no differences between the larval forms of these species. Furthermore, the present work shows that the metric data of the larvae of these two species overlap (see Table 2). As a result, we consider A. monosolenidion as a subjective junior synonym of A. incarnatum .
Additionally, the genus Monotrombium Zhang, 1995 in Zhang and Norbakhsh (1995), which is represented by only one larval species, M. simplicium Zhang, 1995 , is characterized by the presence of a single solenidion on genua II-III and a single seta on coxa II ( Zhang and Norbakhsh, 1995). The larva of M. simplicium differs from the larva of A. incarnatum by the presence of only a single seta on coxa II (coxa II has two setae in the larva of A. incarnatum ). Future experimental and/or molecular studies could clarify the taxonomic status of the genus Monotrombium .
