“…have morphological characteristics that correspond to the descriptions made by Gusakov and Gagarin (2015). On the other hand, Sen et al (2011), point out that in males the upper end is ventrally more curved than in females, with blunt In the morphological and morphometric analysis of Mononchus spp., these individuals resemble the characteristics reported previously (Lordello, 1958): body and tail length of 788-924 µm and 53.5-68.8 μm, respectively. However, other descriptions of the genus indicate different sizes for body length: 1000-2950 μm (Siddiqi et al, 2015), values higher than the ones reported here.…”

Plant-parasitic nematodes cause 14 % of annual losses in different crops in the world and there are more than 35 genera of phytoparasitic nematodes associated with the rhizosphere of the papaya crop (Carica spp.), being the most important the root-knot nematode (Meloidogyne spp). The present study aimed to carry out the morphological identification of the genera of nematodes associated with the cultivation of Andean papaya (Carica pubescens), in Sandia district, Puno, Perú. One-hundred and fifty-five soil and roots samples from eight communities were evaluated. The samples were processed by the centrifugal fluctuation method in sucrose solution and subsequent identification of the nematodes at the genus level, using the dichotomous key of Mai and Mullin. We found the genus Meloidogyne, Pratylenchus, Helicotylenchus, Mesocriconema, Apelenchus, Dorilaymus, Tylenchus, Xiphinema, Mononchus, Discocriconemella, Trichodorus and other unidentified free-living nematodes. This information may allow the design of an integrated nematode management plan in Andean papaya crops.

The new species Iotonchus lotilabiatus n. sp. from Bat Xat Nature reserve in Lao Cai Province, Vietnam is described and the molecular data (18S and 28S rDNA) are given. Females of the new species are characterized by large body size ( L = 3.8-5.2 mm); barrel shaped buccal cavity of large size (41–54×70–89 µm) with dorsal tooth apex located 22 to 23.5% of buccal cavity length from its base; reproductive system didelphic-amphidelphic, vagina long, corresponding almost half of body width at the vulva with distinct parrefringens vaginae , sclerotized and triangulated pieces in optical section; tail long filiform, ventrally arcuate, with three small caudal glands in tandem and prominent terminal spinneret. Males with spicules 119 to 148 µm in length, and slender, slightly curved gubernaculum, 39 to 44 µm long and with 13 to 14 ventromedian supplements. The new species Iotonchus lotilabiatus n. sp. is closest to I. miamaensis (Khan and Araki, 2002), but differs by having larger size of body length and buccal cavity, lower position of dorsal tooth apex; longer female tail with lower c but higher c′ ratios and the presence of advulval cuticular structures.
