Six Asian species of Aulacaspis are studied on the supposition that they are related to A. auslralis Brimblecombe and A. constricra Takagi and De Faveri, mangrove-associated species in Australia: A. crawii (Cockerell) [=Diaspis crawii var. fulleri Cockcrell], A. mischocarpi (Cockerell and Robinson) [=Phenacaspis thoracica Robinson, n.syn.], A. alangii, n.sp. (Borneo, on Alangium), A. otophorae, n.sp. (Palawan, on Otophora), A. shoreae, n.sp. (Malaya, on Shorea), and A. fici, n.sp. (Malaya, on Ficus). One of them, A. crawii, is closely related to A. australis; the other five species are lumped under the mischocarpi species group, which may be responsible for the origin of A. constricta. Four of the six species, together with A. litsearum, n.sp. (India, on Litsea) and A. rosae (the type species of the genus) added for comparison, are examined for their growth patterns in the stage of the adult female by means of pairing full-groWn adult females with teneral ones from the same samples.

TAKAGI, S., 2015. Notes on scale insects of the genus Aulacaspis occurring on grasses and herbs (Sternorrhyncha: Coccoidea: Diaspididae). Ins. matsum. n. s. 71: 121¬177, 26 figs. Species of Aulacaspis recorded from poaceous grasses and herbaceous plants are enumerated and annotated. Three pairs of closely related species are picked out from them, and the species in each pair are revised as to their relationship: Aulacaspis madiunensis (=Chionaspis madiunensis Zehntner) and Aulacaspis takarai Takagi, both known as pests of sugarcane, the former in tropical Asia and other regions and the latter in the Ryukyu Islands; Aulacaspis herbae (=Chionaspis herbae Green) and Aulacaspis discorum Hall and Williams, grass-associated species described from the Indian Subcontinent; Aulacaspis trifolium Takagi and Aulacaspis isobeae Takagi, hypogeal species collected on Trifolium pratense in Honsyu and on an undetermined herbaceous plant in Okinawa, respectively. Four species are described as new: Aulacaspis takahashii found on an undetermined orchid intercepted at quarantine inspection, and three species, Aulacaspis labucola, Aulacaspis trichosanthis, and Aulacaspis hodgsoniae, all collected from wild cucurbitaceous plants in the Malay Peninsula. © 2015, Graduate School of Agriculture, Hokkaido University.

'Atypical' species of Aulacaspis, scale insects referable to the genus but not conforming with the type species in body shape, are dealt with; 21 species including 17 new species are described, three undetermined and seven known species are briefly noted, and 10 published names are mentioned. Not all of them are closely related to each other, so that the atypical species do not form their own taxonomic group within the genus. The calcarata species group is composed of nine species similar to each other in certain pygidial characters; five of them are typical and the other four atypical in body shape, the latter exhibiting two types of body shapes. These species suggest the emergence of the different body shapes within the group. The antennae of the first insta rare six-segmented in six species, whereas five-segmented in many others; the possibility that the number of the antennal segments sometimes changes between closely related species is not excluded.

Aulacaspis cupulifera and Aulacaspis cylicophora, n. spp., are described from the Ryukyu Islands, Japan. They are extraordinary in having 'cupulae' on the ventral surface of the mesothoracic region, but in other characters they are very similar to Aulacaspis yabunikkei. The cupulae are supposed to be suckers useful in test construction. A. cupulifera was collected in November on Neolitsea aciculata at two localities in Tokuno-Sima, and A. cylicophora in March on Neolitsea sericea in Okinawa. One of the two samples of A. cupulifera has full-grown and teneral adult females mounted mostly from the same leaves and separated clearly into two successive generations, parental and offspring. The adult females of the offspring or hibernal generation tend to have more numerous dorsal macroducts and perivulvar disc pores, the mean values of the total numbers being significantly different statistically. This phenomenon requires attention on seasonal ecophenotypic variation in comparing characters taxonomically The adult females of the other sample are considerably grown but still juvenile, and those of A. cylicophora are fully grown; these females probably belong to the hibernal generation, in which the two species may properly be compared.

'Aulacaspis yabunikkei' or the yabunikkei complex of Aulacaspis comprises three distinct species including two new ones in Japan: A. yabunikkei Kuwana associated with Cinnamomum spp., A. neolitseae occurring on Neolitsea sericea usually and on Cinnamomum japonicum occasionally, and A. sirodamo collected from N. sericea. The grounds adopted for recognizing the three species are explained. A small sample from Taiwan agrees with the revised concept of A. yabunikkei; two other samples collected in Taiwan and Hong Kong are referred to A. sirodamo tentatively. Seven other species of Aulacaspis, all occurring on Lauraceae but not particularly related to the yabunikkei complex, are described: Aulacaspis ferrisi Scott, originally described from 'Kwangtung', China, and represented in the present study by samples collected in the Kowloon Peninsula, Malay Peninsula, Kathmandu Valley, and South India, and six new species occurring in the Malay Peninsula, A. obconica, A. ulukaliana, A. medangena, A. kedahana, A. cinnamomorum, and A.jeraiana. © 2014 Graduate School of Agriculture, Hokkaido University.
