A new and a known species of the genus Mesorhabditis (Osche, 1952) Dougherty, 1953 associated with the larva of longhorn beetle (Cerambycidae) and ground beetle (Scarabaeidae)

A new isolate of Mesorhabditis monhystera (Bütschli, 1873) Dougherty, 1955 (Rhabditida: Rhabditidae): re-evaluated with molecular data and scanning electron microscopic observations

“…The molecular data of the present population of M. monhystera and the other previously reported isolates (MT710269; ON693986; MT710271) revealed close relationships with M. denticulatus Mahboob and Jahan, 2021; however, the present population of M. monhystera showed closeness to M. denticulatus and M. litoralis Yeates, 1969 in appearance of lip region and labial sensilla, shape and size of the male tail, and similar shape of spicules. However, M. monhystera could be differentiated from the latter two species in having females with conoid (vs. slender) tails and arrangement of genital papillae in five (vs. nine) pairs.…”

“…Males have not been reported in Mesorhabditis acuminata (Kreis, 1929) Dougherty, 1955; Mesorhabditis capitata Loof, 1964; Mesorhabditis cranganorensis (Khera, 1968) Andrássy, 1983; M. dunensis Khera, 1971; Mesorhabditis sambharensis Khera, 1971; and Mesorhabditis signifera (Baranovskaya, 1959) Baranovskaya, 1962. Only a few species such as M. acuticauda (Shokoohi et al ., 2014), Mesorhabditis minuta (Boström, 1991; Abolafia & Peña-Santiago, 2009) belonging to the Spiculigera- group, and Mesorhabditis microbursaris (Mahboob and Jahan, 2021) belonging to the Monhystera- group have been described based on scanning electron microscopic observations. Likewise, Mesorhabditis acidophila (Borgonie et al, 2010) and Mesorhabditis monhystera have been molecularly characterized.…”
