RESUMO
Oryctophila bonaerensis sp. nov. parasitizing curculionid beetle larvae from Argentina, is described and illustrated. The species is characterized by a prominent genital cone and a short and filiform tail appendage. Female with vulva at midlenght of body, vagina long, S-shaped, monodelphic, opistodelphic. Male with one club-shaped spicule. Genital papillae arranged as follows: one pair of large preanal papillae and three pairs of postanal papillae of various sizes: a pair of medium sized papillae is immediately posterior to the anus, followed by a pair of large papillae, and one pair of small papillae at the base of the caudal appendage.

RESUMO
Una nueva especie, Hexamermis paranaense sp. nov. (Nematoda, Mermithidae), parásito de larvas del gusano blanco, Diloboderus abderus Sturm, 1826 (Coleoptera, Scarabaeidae), se describe e ilustra. Esta nueva especie se caracteriza por poseer anfidos pequeños, con la apertura en forma de bolsillo, parte anterior de la vagina muscular, con una rama que desciende y forma un lazo antes de la conexión al útero, tres hileras de papilas genitales: la hilera de posición ventro-lateral dividida en dos hileras con ocho papilas en la hilera externa y con seis papilas en la interna; la hilera ventral con una papila, seguida de cuatro pares, todas en posición preanal y dos pares, interrumpidos por tres papilas, seguida de un par, una simple, y un par, todas de posición postanal.
A new species, Hexamermis paranaense n. sp. (Nematoda, Mermithidae), a parasite of larvae of Diloboderus abderus Sturm, 1826 (Coleoptera, Scarabaeidae) is described and illustrated. This new species is characterized by amphids small, amphidial opening pocket-shaped, the anterior portion of the vagina muscularized and slightly protruding with a descending branch forming a loop before joining the uterus, and three rows of genital papillae: the ventrolateral divided in two rows with eight papillae in the outer row and with six papillae in the inner one; the ventral row with four pairs and one single preanal papillae, and with two pairs, a triplete, one pair, a single and one pair postanal papillae.

RESUMO
Una nueva especie Blatticola cristovata n. sp. (Oxyurida, Thelastomatidae) parásita del grillo Anurogryllus muticus (De Geer, 1773) (Orthoptera, Gryllidae) en Argentina, se describe e ilustra. Esta es la primera especie del género Blatticola que se encontró parasitando a grillos. Esta nueva especie se caracteriza por tener las hembras la cutícula anillada a lo largo de todo el cuerpo, la abertura bucal triangular rodeada por ocho papilas cefálicas, el estoma corto con tres pares de placas esclerotizadas dispuestas en dos líneas, anfidios pequeños en forma de poro, esofago dividido en tres partes, una anterior con un corpus cilíndrico, un istmo distintivo, y un bulbo basal con valvas, el anillo nervioso situado rodeando el corpus, el intestino ensanchado anteriormente, huevos ovales, de cáscara lisa, con un lado recto y el otro con una cresta longitudinal. Macho con un par de papilas preanal, uno adanal y dos pares de papilas postanales, y apéndice caudal corto, cónico y punteagudo.
Blatticola cristovata n. sp. (Oxyurida, Thelastomatidae) a parasite of the cricket Anurogryllus muticus (De Geer, 1773) (Orthoptera, Gryllidae) from Argentina, is described and illustrated. This is the first species of the genus Blatticola found parasitizing cricket. This new species is characterized in females by having the cuticle annulated through the body length, the mouth opening is subtriangular and surrounded by eight cephalic papillae, the stoma is short with three pairs placed in two rows of cuticular sclerotised plates, amphids in small pore shaped, oesophagus is divided into three parts, anterior cylindrical corpus, isthmus distinct, and basal bulb valved, the nerve ring is situated around the middle of corpus, the intestine is wide broad anteriorly, oval eggs, smooth shell, with a straight side, and the other side with a band running longitudinally. Males with one pair of preanal, one pair of adanal and two pairs of postanal papillae, and the tail appendage short, conical and pointed.
