Other specimens: 1♁ 1♀, same data as paratype. Etymology. The name of the new species is derived from the processes on male tenth abdominal tergite stout, from Greek erromen - (stout). Discussion. The new species is similar to Homogryllacris obtusitubera Li, Dou & Shi, 2019 based on morphology of the processes on male tenth abdominal tergite, but it can be distinguished from the latter in the following: body obviously large, body length about twice as long as that of the latter species; posterior margin of male subgenital plate with a triangular notch; female subgenital plate is of almost equal length and width, posterior margin subtruncate. Furthermore, DNA sequencing was implemented of these two species based on COI, the genetic distance between them is more than 8% (unpublished). Hence, with a combination of morphological and molecular evidence, we regard it as a new species of Homogryllacris.

Background: Multidrug resistance (MDR) is one of the primary causes of tumor chemotherapy failure. Therefore, it is essential to uncover new drug treatment protocols. In the current study, employing chitosan (CS) and sodium tripolyphosphate (TPP) as carriers and cross-linking agents, the proanthocyanidins (PHL)/poly (lactic-co-glycolic acid) (PLGA) were encapsulated by emulsion solvent evaporation, through which the cationic CS-PLGA-PHL nanosystem was obtained. The effectiveness of CS-PLGAPHL on the invasion and migration of human oral squamous cell carcinoma cells was discussed, as were their potential mechanisms. Methods: A CS-PLGA-PHL nanosystem was constructed by emulsion-solvent evaporation. The size distribution, dispersion, and morphology were characterised by the laser particle size analyser and transmission electron microscope. Human oral squamous cell carcinoma drug-resistant cell lines SCC131/R and SCC-15/DDP were cultured in vitro. The two cell types were induced at different concentrations by CS-PLGA-PHL, after which a CCK⁃8 experiment was performed to determine the effect of CS-PLGAPHL on the proliferation of the two cell lines. The 50% inhibitory concentration (IC50) of CS-PLGAPHL was calculated at different time points. The transwell chamber experiment was performed to identify the effects of CS-PLGA-PHL on the migration and invasion of OSCC cells. The expression levels of MMP-2 and MMP-9 were detected by Western blot and q-PCR. objective: The preparation of nano system to reduce the proliferative activity of OSCC cells together with inhibit the migration, invasion and tumor growth of OSCC cells Results: CS-PLGA-PHL is well dispersed. The PDI appeared to be lowest when the mass ratio of chitosan to PLGA equaled 1:15. CS-PLGA-PHL exhibited a marked effect in inhibiting the proliferation of SCC131/R and SCC-15/DDP as well as the invasion and migration. CS-PLGA-PHL was able to downregulate the expression of MMP-2 and MMP-9 genes and proteins significantly in drug-resistant cell lines. Conclusion: CS-PLGA-PHL for oral squamous cell carcinoma has been successfully prepared to exert significant inhibition on the proliferation, invasion, and migration of OSCC cells. The mechanism involved was possibly related to the down-regulation of MMP-2 and MMP-9 expression by CS-PLGA-PHL. result: CS-PLGA-PHL is well dispersed. The PDI appeared to be lowest when the mass ratio of chitosan to PLGA equaled 1 ∶ 15. CS-PLGA-PHL exhibited a marked effect in inhibiting the proliferation of SCC-131/R and SCC-15/DDP as well as the invasion and migration. CS-PLGA-PHL of was able to downregulate the expression of MMP-2 and MMP-9 genes and proteins significantly in drug-resistant cell lines other: None

Body: ♂ 9.5–10.9, ♀ 12.6–12.9; pronotum: ♂ 3.9–4.5, ♀ 3.5–3.9; tegmen: ♂ 9.2–12.2, ♀ 10.9–13.8; hind femur: ♂ 9.1–9.5, ♀ 10.2–10.5; ovipositor: 11.1–11.4. Etymology. The name of this new species is named for morphology of male cercus, from Latin ‘ arct -’ (narrow) and ‘ lamin -’ (lamellar). Discussion. The new species resembles Microconema clavata (Uvarov, 1933), but it differs from the latter in: male cercus on inner basal area with a narrow lamellar extension on dorsal margin and ventral margin respectively; subgenital plate nearly rectangular, with a median longitudinal furrow distinctly. Ventral margin of ovipositor with some small blunt teeth in subapical area.
