The genus Tinocallis Matsumura, 1919 is one of the large genera of the subfamily Calaphidinae with 19 species worldwide. From recent expeditions in Laos, we recognized the heavy infestation of Tinocallis himalayensis Ghosh, Ghosh & Raychaudhuri, 1971, which is new record in Laos, on Queen's crape-myrtle, Lagerstroemia speciosa (Lythraceae). In this paper, the diagnosis and illustrations for the alate viviparous female are provided with the images of live aphids and damage on host plant.

Intraspecific diploid androgenesis was achieved in mud loach (Misgurnus mizolepis) by the inhibition of the first mitotic division using combined thermal treatment. A combined thermal treatment (heat shock at $40.5\;^{\circ}C$ for 120 sec followed by cold treatment at $1\;^{\circ}C$ for 45 min) applied to the 1st metaphase of cell division (28 min post insemination at $25\;^{\circ}C$) successfully recovered viable androgenetic diploidy. Mean hatching success of the androgenetic diploid group was 29.6%, and the average yield out of total eggs taken was about 7% assessed at 1 week of age. However, relatively large variations in the yield of diploid androgenesis were observed among different egg batches used as cytoplasmic donors. Successful diploidization was confirmed by flow cytometric analysis, and parthenogenic reproduction in a paternal exclusive manner was verified with transgene dosage. Significant mortality was found in most androgenetic groups especially from hatch to 1 month of age, although such mortality was stabilized later.
