Redescription of an insect-associated nematode, Reiterina typica (Stefański, 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
(Stefański, 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 ± 123 μ m long in males and 1221 ± 188 μ m long in females, V%
= 50.1-57.7, female tail conoid (94.5 μ m, c = 13, c′ = 3.3), male tail conoid (36
μ 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 μ 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 .
