A total of 42 specimens of Argyrops spinifer were caught from Iraqi territorial waters during the period from October 2019 till September 2020. The adult nematodes were isolated from the infected fishes. Morphological features of both males and females of nematodes matched with that of Dichelyne (Cucullanellus) tripapillatus (Gendre, 1927). This nematode is distinguished by the location of nerve ring in relation to the length of oesophagus, as well as the distribution of the ten caudal papillae of males. The record of this species and its subgenus represent its first one in the Arabian Gulf and Iraq.

The present study identifies one species of the genus Octopus in the order: Octopoda (Cephalopoda: Mollusca), recorded forthe first time in the Iraqi coastal waters and Arabian-Persian Gulf. The study extended from January 2019 to December of thesame year. The Octopus specimens were seasonally obtained from the fishing trawlers operating in the Iraqi coastal waters inthe South of Al- Fao District, Basrah- Iraq, NW Arabian Gulf. The Octopus was identified as O. vulgaris in Iraqi coastal watersdepending on morphological features. The habitats of living specimens are briefly described. Some observations were reported on the occurrence of this species and the measurement of some environmental factors. The species was identified up to spe-cies level using standard literature. This species looks similar morphologically to the species which is already identified from the other areas around the world. The present study records significant expansion in the distribution range of this species.

Summary The Desmodoridae is a diverse and widespread family of free-living nematodes. Here, we provide the first record of the group in the Persian Gulf and describe three new species: Metachromadoroides sinuspersici sp. n., Zalonema iranicum sp. n. and Z. supplementorum sp. n. Metachromadoroides sinuspersici sp. n. is characterised by finely annulated cuticle, short and stout cephalic sensilla, amphidial fovea on cuticular thickening, pharyngeal bulb well developed and partitioned into three sections, absence of precloacal supplements, and presence of 6-8 pairs of rounded postcloacal papillae. Zalonema iranicum sp. n. is characterised by papilliform subcephalic sensilla (best observed with SEM), convex cephalic capsule, large multispiral amphidial fovea with 4-5 turns in both males and females, buccal cavity with one ventrosublateral and two dorsal teeth and posterior body of males with lateral alae extending from the last third of the body to the cloacal aperture and ventral alae extending 1395-2250 μm anterior to the cloacal aperture, and no precloacal supplements. Zalonema supplementorum sp. n. is characterised by four subcephalic sensilla 1-2 μm long, multispiral amphidial fovea with three turns in both males and females, buccal cavity with one dorsal and two ventrosublateral teeth, males with lateral alae present on each side of body from posterior half of body to cloacal aperture, ventral alae extending 942-1257 μm anterior to cloacal aperture, strongly cuticularised spicules 41-43 μm long, and 12-16 precloacal supplements. Near full length SSU and partial D2-D3 LSU sequences are provided for M. sinuspersici sp. n. and Z. iranicum sp. n., and the COI sequence is provided for Z. iranicum. The SSU phylogeny suggests a close relationship between M. sinuspersici sp. n. and Metachromadora and Metachromadoroides species and the monophyly of Zalonema (after currently available data). The LSU phylogeny suggests an affinity between Metachromadoroides and Zalonema with Spirinia and Acanthopharynx, respectively.

AbstractAn invasive pest,Tuta absoluta(Meyrick) has been observed infesting tomatoSolanum lycopersicumL. (Solanales: Solanaceae) in Central Uganda. The affected farmer made the report, and upon visiting the farm, we observed tiny larvae, green to cream in colour with a black head feeding on tomato leaves, fruit, as well as tender stems. Also, we saw several tiny moths resting on screen house linings. Delta traps baited with TUA-Optima®(Russell IPM) were set in and around the affected farm. Dozens of moths were attracted and trapped on the sticky surface of the traps. The team tentatively identified the insect asT. absoluta. Scientists at the International Centre of Insect Physiology and Ecology (icipe) in Nairobi, Kenya identified the insect using morphological features and molecular techniques.

A new Alaninema species associated with leaf-veined slugs (Athoracophoridae) in New Zealand is described and illustrated. Alaninema ngata n. sp. is characterised by a very long, cylindrical body, rounded head bearing two circles of cephalic papillae and amphids, shallow stoma with three bifid teeth, muscular, cylindroid pharynx lacking valves, enlarged, rounded cardia, nerve ring crossing the anterior intestine, excretory pore situated just posterior to nerve ring, monodelphic females with post-median vulva, thick-shelled eggs covered with prominent tubercles, monorchic males with short testis reflection, reduced number of male genital papillae, strong equal spicules and gubernaculum and tail tip bearing about 20 digitate processes. It is distinguished from A. venmansi and A. njoroensis by having a larger body size (mean 8.3 mm and 13.8 mm in males and females, respectively vs 8.2 mm females in A. venmansi and 4.8 mm and 5.5 mm in A. njoroensis males and females, respectively) and more anterior vulval position (V = 51.6 vs 70 and 66.4 in A. venmansi and A. njoroensis, respectively). Analyses of a partial 18S rDNA sequence indicate that A. ngata n. sp. is affiliated to the Panagrolaimorpha. The systematic position, host range and distribution of A. ngata n. sp. are discussed.

SummaryDetails about the record of a juvenile mermithid roundworm parasitizing the bark spider Caerostris sumatrana Strand, 1915 from Thailand are presented. The morphology and ecology of both organisms is discussed. Morphological features suggest this juvenile nematode belongs to the genus cf. Aranimermis. Due to the subadult stage of parasite, identification to species-level was not possible. This first report of a nematode infection in C. sumatrana with several recent findings from other studies significantly adds to the current inventory of mermithids parasitizing spiders. Moreover, our finding is among the first record of this host-parasite interaction from Southeast Asia.

Here, we present the first record of Eptesicus brasiliensis argentinus Thomas, 1920 for the province of Entre Ríos, Argentina. This subspecies was originally described as a full species (E. argentinus) based on its morphological features that clearly separate it from all other species of the genus. However, it was later treated as a subspecies of E. brasiliensis by Cabrera (1957), a treatment that was followed by all authors until today. Our record raises the number of bat species for the province of Entre Ríos to 21. This locality represents the fourth record for this subspecies in Argentina, after 35 years since the last known record was obtained. Its geographic range is extended by approximately 130 km to the south, which represents the southernmost known record for this subspecies, and a new ecoregion, the Espinal, is added to its distribution.

Nymphs and adults of Tingis americana Drake, 1922 were found feeding on leaves of Handroanthus heptaphyllus (Vell.) Mattos and Handroanthus chrysotrichus (Mart. ex A. DC.) Mattos in the Botanic Garden, Porto Alegre, state of Rio Grande do Sul, Brazil. This is the first record of T. americana on these host plants and in the southern Brazil. We aimed to compare the nymphal development on both hosts and to analyze the reproductive parameters on H. heptaphyllus (25 ± 1ºC; 60 ± 10% RH; 16 h photophase). The mean nymphal period (days) was shorter in individuals reared on H. heptaphyllus (12.69 ± 0.076) than on H. chrysotrichus (19.11 ± 0.208) (P < 0.0001), however, nymph viability was similar. On H. heptaphyllus, the mean embryonic period lasted 12.32 ± 0.274 days and the egg viability was 92%. The mean total and daily fecundity were 310.0 ± 19.40 eggs/female and 7.46 ± 0.302 eggs/female/day, respectively. Paired males and females showed similar longevity (P = 0.0691), while unpaired females lived longer than unpaired males (P = 0.0460).

The larva and pupa of the sagrine chrysomelid Mecynodera balyi Clark, 1864 are described and life history notes provided for this species. The larva of Mecynodera balyi is spermophagous and feeds inside seed pods of Pandorea, a vine in the Bignoniaceae. This is the first record of larval spermophagy in any chrysomelid other than Bruchinae, the sister subfamily to Sagrinae. Several morphological features of the immature stages are newly recorded for the Sagrinae. The implications of these new data for systematic placement of Sagrinae are discussed.
