Stenichnus styriacus is redescribed.Genera and species of the subtribe Hecalina from the Indian subcontinent tend to be evaluated. Three genera, Hecalus (28 species), Linnavuoriella (1 species), Thomsonia (4 species) comprising 33 valid species Wang’s internal medicine reported from the Indian subcontinent are recognized. Three brand-new types, Hecalus shanayai sp. nov. (Maharashtra Chikhaldhara), Hecalus tumidus sp. nov. (Himachal Pradesh Kinnaur) and Thomsonia assymetrica sp. nov. (Meghalaya Barapani) from Asia are described and illustrated. An annotated checklist and key to genera of Hecalina through the Indian subcontinent tend to be provided.The present paper handles the revised description of some less popular silent-slender crickets of Euscyrtinae (Orthoptera Gryllidae) from the tropical hilly tracts of Asia. Besides, we describe an innovative new types, Euscyrtus tubus sp. nov., and report the event of Euscyrtodes ogatai (Shiraki, 1930) from India.Two new species of cave-adapted ground beetles are explained and illustrated from Sichuan Province, southwestern China Jujiroa zhouchaoi sp. nov. through the calcareous conglomerate cave Shenxian Dong in Mt. Zhaogong (Dujiangyan, Chengdu) and Pterostichus (Huaius) hanwang sp. nov. from the limestone cave Hanwang Dong (Chaotian, Guangyuan). A brand new locality for Jujiroa deliciola Uéno and Kishimoto, 2001 is provided. Keys to types of the genus Jujiroa Uéno, 1952 while the subgenus Huaius Tian and Huang, 2019 (in Tian et al. 2019) are also supplied.We describe a brackish-water calanoid copepod Acartia (Acanthacartia) cagayanensis sp. nov. gathered from river estuaries within the northernmost Luzon, the Philippines. The new types has actually a few characteristic features being typical to your A. plumosa team (A. (A.) plumosa Scott T., 1894, A. (A.) sinjiensis Mori, 1940 and A. (A.) tropica Ueda Hiromi, 1987); specifically, a short apical back in the lengthy terminal section of male left leg 5, which will be special to the team. The morphological top features of genetic homogeneity A. cagayanensis sp. nov. distinctive from those for the A. plumosa team would be the barrel-shaped genital double somite in addition to cylindrical basal area of the terminal segment of female leg 5. Among the list of species in the group, A. cagayanensis sp. nov. is closest to A. sinjiensis in terms of the spinule patterns from the female antennule, the posterior place regarding the prosome, and the male second urosomite. The genetic analysis using DNA sequences of mitochondrial gene cytochrome oxidase subunit I (COI) revealed that A. sinjiensis from Japan and A. cagayanensis sp. nov. differed by 16.5-16.9%, as opposed to a small variation (0.0-0.5%) within each populace. We confirmed that earlier records of A. sinjiensis through the Philippines are not A. cagayanensis sp. nov., and therefore, A. cagayanensis sp. nov. may be the 3rd types of the subgenus Acanthacartia Steuer, 1925, after A. sinjiensis and A. (A.) tsuensis Ito, 1956.A complementary information of Panonychus caricae Hatzinikolis, 1984, is presented based on the morphology of adult feminine and male individuals gathered from fig trees (Ficus sp., Moraceae) in Greece. Morphological differences between Panonychus caricae and two closely associated species, Panonychus ulmi (Koch, 1836) and Panonychus hadzhibejliae (Reck, 1947), tend to be discussed. Panonychus caricae can be separated from two various other Panonychus species utilizing the period of the female dorsal setae in combination with the ratio involving the amount of female dorsal opisthosomal setae f2 and h1, and also the ratio between the amount of dorsal setae sc1 and h1. A phylogenetic maximum likelihood tree had been constructed on the basis of the cytochrome c oxidase subunit we (COI) gene of mitochondrial DNA (mtDNA) from 10 types of the subgenus Panonychus s.str. (such as the re-described types P. caricae) plus the just two species of the subgenus Sasanychus. The phylogenetic tree indicates why these 12 species tend to be plainly divided from each other. The 2 subgenera, Panonychus s.str. and Sasanychus, comprise strongly supported monophyletic clades with 98% bootstrap values. The convergence of molecular and morphological data (dorsal setae set on tubercles or otherwise not, quantity of tactile setae on tibiae I and II, and patterns for the dorsocentral striae) suggests that Sasanychus shouldn’t be categorized beneath the genus Panonychus. Consequently, molecular and morphological research aids the resurrection associated with the genus Sasanychus, which contains two types, S. akitanus (Ehara) and S. pusillus Ehara Gotoh, as distinct from Panonychus. A vital to the globe species of Panonychus and Sasanychus can also be supplied.We report recent results of Isthmohyla pictipes (Cope, 1875) in the Cordillera de Talamanca, Costa Rica, approximately 2 decades after it had been last signed up. We provide notes on microhabitat use, shade difference, exterior morphology of adults and larvae, and geographical difference, and discuss some taxonomic characters used to differentiate I. pictipes from I. tica (Starrett, 1966) and I. xanthosticta (Duellman, 1968). We also report fluorescence in the ventral areas of I. pictipes. Our results are anticipated to shed light on the taxonomy of this species and really should be useful in additional population assessments and conservation plans.Eight brand new species of Duplominona (Platyhelminthes, Proseriata, Monocelididae) are described from the Pacific coastline of Panama. They differ from their congeners in the detailed morphology of tough structures from the copulatory organ. Duplominona basidilatata n. sp. has a cirrus provided with 5-6 rows of triangular spines, 3-8 μm long, with a sizable, flat, poorly sclerotized basis. D. hystricina n. sp. has 10-12 rows of needle-shaped spines, 3.5-15 μm long, with a swollen basis. The cirrus of D. hyperhystricina n. sp. is offered with 20-25 rows of slim spines 1.5-9 μm long, with a recurved distal tip. In D. veracruzensis n. sp., cirrus spines increase abruptly in proportions, from 1.5-2 μm to 6-7 μm. D. uniserta n. sp. has a very long seminal vesicle and a small cirrus, given one girdle of hook-shaped spines, 3-5 μm long. D. macrodon n. sp. has one girdle of large, triangular spines, 8-18 μm very long. Both D. trimera n. sp. and D. pseudotrimera n. sp. have a tripartite end, and their cirrus receives a stylet. In D. trimera n. sp., the stylet is surrounded by 15-20 rows of spines, 6.5-10 μm long, while D. pseudotrimera n. sp. has 6-8 rows of huge spines, 7-22 μm long. D. uniserta n. sp. and D. aduncospina Curini-Galletti, 2019 through the Copanlisib concentration Caribbean coast of Panama have few rows of morphologically nearly identical spines, and so are feasible candidates as trans-isthmian geminate species. The existence of types with a tripartite tail on both sides associated with Isthmus of Panama shows the likelihood of additional geminate species pairs; but, no help might be gotten based on the morphology of the tough frameworks.
