039887CD4A27FFD30E9FFBA08E5DFE3C.taxon	diagnosis	Diagnosis: Myrmecophilus jordanicus n. sp. differs from M. (Myrmophilina) ochraceus and M. (Myrmophilina) cyprius Stalling, 2017 in having the overall darker body and visibly shorter setae (setae on frons only about half as long as the diameter of the antennae on the third segment, but about as long as the diameter of the antennae in M. ochraceus and M. cyprius; appressed setae on pronotum and tergites about 0.02 mm long, while they are about 0.03 mm in M. ochraceus and M. cyprius). The ovipositor of M. jordanicus n. sp. has straight outer edges in the apical area, whereas it has convex outer edges in M. ochraceus and M. cyprius. The new species differs from M. (Myrmophilina) americanus in being paler and much larger (the latter is dark reddish brown with a pale beige mesonotum, and has an average body length of 1.9 mm in females and 1.4 mm in males) and in having only one spine in the proximal third on the basitarsus (usually two spines, one proximal and one distal, are present in M. americanus). The female ovipositor is elongated in M. jordanicus n. sp., whereas the outer valvae of the ovipositor are ladle-shaped in M. americanus.	en	Stalling, Thomas (2024): Myrmecophilus jordanicus, a new species of ant cricket from Jordan and Israel, with notes on the synonymy of Myrmecophilus nigricornis (Orthoptera: Myrmecophilidae).

039887CD4A27FFD30E9FFBA08E5DFE3C.taxon	biology_ecology	Biology and habitat: The new species lives in the nests of the harvester ants of the genus Messor Forel, 1890. In Jordan, the species was found in the semi-arid Mediterranean bioclimatic zone in stony grassland with small perennial bushes grazed by goats (Shawbak, Fig. 3), and in the sub-humid Mediterranean bioclimatic zone in limestone hills, covered by evergreen Kermes Oak forest (Quercus coccifera), partly cultivated with olive groves and crop fields (Ajloun). Both localities belong to the Mediterranean vegetation region (Al-Eisawi 1996). In Israel, the species was found in the transition area — between the Mediterranean zone and a semidesert consisting of bare hills — covered by the Mediterranean scrub comprising Sarcopoterium spinosum, Amygdalus sp. and Crataegus sp., with geophytes such as Drimia maritima (L. Friedman, pers. comm., Fig. 4).	en	Stalling, Thomas (2024): Myrmecophilus jordanicus, a new species of ant cricket from Jordan and Israel, with notes on the synonymy of Myrmecophilus nigricornis (Orthoptera: Myrmecophilidae).

039887CD4A27FFD30E9FFBA08E5DFE3C.taxon	discussion	Remarks: Myrmecophilus jordanicus sp. n. belongs to the subgenus Myrmophilina Silvestri, 1912 with respect to the following characteristics: outer valvae of female (viewed laterally) rounded (vs. double-pointed in the subgenus Myrmecophilus); setae on the front and antenna long, erect and bushy (vs. short and inconspicuous in the subgenus Myrmecophilus); hind basitarsus with one spine in the proximal position (two or three dorsal spines in the proximal, medial and sometimes distal positions in the subgenus Myrmecophilus). The internal male phallic complex has not been dissected in order to preserve the only existing male paratype, and because its significance for the differentiation of the Myrmecophilus species is unclear.	en	Stalling, Thomas (2024): Myrmecophilus jordanicus, a new species of ant cricket from Jordan and Israel, with notes on the synonymy of Myrmecophilus nigricornis (Orthoptera: Myrmecophilidae).

039887CD4A23FFD00E40FE2D8D33FB3D.taxon	materials_examined	Material examined: Israel: Judean Hills: ♀ aDult, Abu Gosh near Jerusalem, 7. v. 1948, A. Moscona (MNHN); Central Negev: ♀ aDult, WaDi AbyaD, 27. iii. 1952, J. Wahrman (MNHN); ♀ aDult, Asluj, 26. xii. 1956, O. Yarkoni (SMNHTAU). Taxonomic status of Myrmecophilus nigricornis Myrmecophilus nigricornis was described by Chopard in 1963 based on material from the Jerusalem area in Israel. According to the original description, the holotype had been deposited in the “ Hebrew University Collection ”, which was transferred to the National Collection of Insects of Tel Aviv University in 1992 and should have been kept in the SMNHTAU, but could not been located (L. Friedman, pers. comm.). Subsequently, I examined the Orthoptera collection of the National Museum of Natural History in Paris that houses a lot of Chopard material, but failed to locate the labelled M. nigricornis holotype there as well. However, a female specimen designated by Chopard as a paratype of this species with the exact collecting data of the holotype was found, labelled as: “ PARATYPE / MNHN-EO-ENSIF 4499 / A. Moscona 7. v. 1948 / Israel Abu Gosh near Jerusalem / Myrmecophilus nigricornis Chp. PARATYPE ” (Fig. 5). Since the data of the holotype corresponded to this specimen instead of the paratype data given by Chopard (1963), I presume that it is the actual holotype, which was mistakenly labelled as a paratype instead of the holotype. We also found two (out of five) assumed paratypes of M. nigricornis in the examined holdings of the SMNHTAU and MNHN, both not labelled as paratypes: one adult female from Asluj [= Mash'abe Sade, 31 ° 00 ' N 34 ° 46 ' E] and another adult female from Wadi Abyad [= Nahal Lavan, 30 ° 54 ' N 34 ° 31 ' E], which probably belongs to M. jordanicus n. sp. Chopard (1963) did not provide any differential diagnosis for M. ochraceus in the original description of M. nigricornis. The presumed holotype, an adult female, clearly shows all the characteristics of the subgenus Myrmophilina. It has a beige coloured body, long setae on the frons and body, an elongated ovipositor with straight outer edges at the tip, which distinguishes it from both M. jordanicus n. sp. and M. americanus. The whereabouts of the holotype of M. ochraceus is unknown (Cigliano et al. 2024); therefore, it cannot be used for verification purpose. Instead, various specimens of M. ochraceus from the author’s collection from the area of the type locality in Sicily have been used for comparison. No characters distinguishing M. nigricornis and M. ochraceus could be found; consequently, M. nigricornis Chopard, 1963 is here considered a junior subjective synonym of M. ochraceus Fischer, 1853.	en	Stalling, Thomas (2024): Myrmecophilus jordanicus, a new species of ant cricket from Jordan and Israel, with notes on the synonymy of Myrmecophilus nigricornis (Orthoptera: Myrmecophilidae).
