Redescription of an insect-associated nematode, Reiterina typica (Stefanski, 1922) Sudhaus, 2011 (Rhabditida: Rhabditidae) found in scarab grubs in Hungary

Three out of four currently accepted species of the genus Reiterina (Rhabditida: Rhabditidae) were described in the early 20th century. The type species of this genus, R. typica (Stefan & PRIME;ski, 1922) Sudhaus, 2011, has several synonyms, with differences in their individual species descriptions, which necessitates its detailed redescription. A population of this species was isolated from scarab beetles in Hungary and is characterised as follows: body 970 & PLUSMN; 123 & mu;m long in males and 1221 & PLUSMN; 188 & mu;m long in females, V% = 50.1-57.7, female tail conoid (94.5 & mu;m, c = 13, c' = 3.3), male tail conoid (36 & mu;m, c = 27, c' = 1.5) with anteriorly opened peloderan bursa supported by nine pairs of genital papillae (1 + 2 + 3 + 3), papillae 4 and 9 open on the dorsal side, and papillae 3 and 8 reaching the edge of the velum, spicules 28-47 & mu;m long. Newly sequenced 18S rDNA genes place Reiterina typica in a clade with other published Reiterina typica sequence and with sequences from the genus Rhabditis.
