Abstract
The correct author and date of availability for Caelidia are noted to be Boisduval, 1835, not
Dejean, 1833 nor Burmeister, 1844. References are provided for a reversal of precedence under
ICZN Article 23.9 to protect the name Parastasia Westwood, 1841.

Introduction
The name Caelidia was first used by Dejean (1833), but without including any available species
name, leaving it a nomen nudum under article 12.2 (ICZN, 1999). Following Neave (1939:515),
it has generally been attributed to Burmeister (1844:371) and treated accordingly as a synonym
of Parastasia Westwood, 1841. This was despite Kuijten (1992:69) pointing out that Burmeister
never actually made the name available. While compiling and clarifying relations between
Dejean names and their synonyms or available counterparts for inclusion in the Interim
Register of Marine and Nonmarine Genera (IRMNG) it was noticed that Caelidia had a
significantly earlier date of availability than quoted in Neave (1939).
When Boisduval published Caelidia marginata (Boisduval, 1835:187), he also validated that
generic name and established C. marginata as its type by monotypy. It is not clear why Kuijten
(1992) treated that species name as available, but failed to reach the logical conclusion that the
generic name was simultaneously made available, and instead treated it as the unavailable
Caelidia Burmeister, 1844. This dating issue is only noted in a very indirect way by Bouchard
and Bousquet (2013:223), who did not point out the consequences of this as it was beyond the
scope of their article.
Results and discussion
As a consequence of this lasting oversight, the name Caelidia Boisduval, 1835 is a senior
subjective synonym of Parastasia Burmeister, 1841 and threatens its nomenclatural stability.
Given that Caelidia has never been treated as a valid genusindeed, even when discussing
Parastasia, it has been mentioned only uncommonly if at allsince it was synonymized by
Arrow (1899:484), and Parastasia is a speciose genus of over a hundred species (Zhao, 2019),
the reversal of precedence (ICZN 1999; Article 23.9) is only appropriate here. The required 25

All genus-group names first proposed or made available for the first time in the third edition of Dejean's catalogue of his beetle collection are recorded. The following 18 names are made available for the first time in Dejean's third catalogue: Batoscelis Dejean [Carabidae], Laphyra Dejean [Carabidae], Sauriodes Dejean [Staphylinidae], Abrobapta Dejean [Buprestidae], Selagis Dejean [Buprestidae], Eurhipis Dejean [Eucnemidae], Anaeretes Dejean [Scarabaeidae], Doryscelis Dejean [Scarabaeidae], Epilissus Dejean [Scarabaeidae], Hoploscelis Dejean [Scarabaeidae], Brachygenius Dejean [Tenebrionidae], Capnisa Dejean [Tenebrionidae], Heterocheira Dejean [Tenebrionidae], Selenomma Dejean [Tenebrionidae], Dactylocrepis Dejean [Curculionidae], Lophodes Dejean [Curculionidae], Heterarthron Dejean [Bostrichidae] and Homalopus Chevrolat [Chrysomelidae]. Eurhipis Dejean, 1836 is considered a junior synonym of Phyllocerus Lepeletier and Audinet-Serville, 1825 for the first time. Abrobapta Dejean, 1836 has precedence over Torresita Harold, 1869.

The population fluctuation pattern of light-attracted beetles was studied from August 1992 to September 1998 (for 73 months) using ultraviolet light-traps set at three vertical levels in a tropical lowland dipterocarp forest in Sarawak, Malaysia. During our study, a general flowering occurred from April to July in 1996, and flowering on a small scale in 1997 and 1998. We analyzed the data for eight scarabaeid and six meloid species, some of which were anthophilous species. Various fluctuation patterns were observed among the beetle species in aspects of both seasonality and correlation with the supraannual phenological pattern. Three large chafer species (Scarabaeidae, Melolonthini) showed a clear seasonal fluctuation pattern with a peak once from March to May every year, the peak monthly catch greatly fluctuating annually. Other scarabaeid beetles did not show such a clear seasonal population pattern and hardly fluctuated annually. Populations of an anthophilous scarabaeid species, Parastasia bimaculata, a specific pollinator of Homalomena propinqua (Araceae), hardly fluctuated, probably because of its response to the constant flowering of its floral hosts. Monthly catches of an anthophilous scarabaeid, Anomala sp., and meloid beetles showed clear supraannual patterns in response to the general flowering and were significantly correlated with the flowering intensity with or without a lag of a month. The fluctuation pattern of meloids suggests a supraannual population fluctuation pattern of their hosts, i.e., megachilid/anthophorid bees.

This study investigated floral visitations of two beetles, Parastasia bimaculata (Scarabaeidae) and Chaloenus schawalleri (Chrysomelidae), and examined associations between beetle visitations and variation in attractant traits, such as quantitative variations of attractants in floral odors and heat generation of spadices in Homalomena propinqua (Araceae). Observations showed P. bimaculata visited pistillate-phase inflorescences most frequently during heat generation, whereas C. schawalleri visited regardless of floral stages and heat generation. Chemical analyses of five dominant components of floral odors showed quantities of 2-butanol, veratrole, and alpha-pinene during the pistillate phase were the most abundant during all floral stages, and increased during heat generation. When testing combinations of these five authentic chemicals, some mixtures including 2-butanol or veratrole or both attracted both beetles, and veratrole attracted C. schawalleri. These results strongly suggested that the increased emission of floral odor attractants which accompanied heat generation influences floral visitations by P. bimaculata, but not by C. schawalleri. We therefore hypothesize that P. bimaculataaculata is a reliable pollinator, and that variation in attractant traits is a honest signal for P. bimaculata to seek rewards. In contrast, C. schawalleri can detect the signal even at low levels, and so visits inflorescences steadily during all floral stages.

The genus Peltonotus Burmeister ( Coleoptera: Scarabaeidae: Dynastinae) includes 19 species that are distributed throughout Southeastern Asia. We describe ten new species of Peltonotus: P. adelphosimilis, P. deltomentum, P. fujiokai, P. gracilipodus, P. kyojinus, P. nethis, P. podocrassus, P. silvanus, P. sisyrus, and P. suehirogarus. We synonymize two names: P. morio sawaii Miyake with P. morio Burmeister and P. sakaii Miyake & Yamaya with P. similis Arrow. Lectotypes are designated for the following species: P. malayensis Arrow, P. nasutus Arrow, and P. similis Arrow. A neotype is designated for P. morio Burmeister. The name P. peninsularis Miyake was not validly described and is an unavailable name. The genus Subpeltonotus Ghai et al. is synonymized with the genus Parastasia Westwood ( Scarabaeidae: Rutelinae). We discuss the contentious nomenclatural history of the genus which was historically placed in the Dynastinae ( tribe Cyclocephalini) and the Rutelinae ( tribe Rutelini or Peltonotini). We discuss characters that support the monophyly of the genus Peltonotus, comment on the natural history and distribution of species in the genus, and provide a key to species.

1. Seasonal patterns in insect population fluctuations have rarely been examined in rainforests of the central part of Southeast Asia where the climate is aseasonal. 2. We examined the seasonality of population fluctuations in a Bornean rainforest phytophagous scarabaeid assemblage (six species of Melolonthinae and seven of Rutelinae). We also investigated effects on abundances of these insects of irregularly fluctuating environmental changes, such as short-term rainfall, and community-level leaf flushing and flowering of canopy trees. Scarabaeids were collected over 6 years by monthly light-trapping. 3. Eight scarabaeid species had clear seasonality in occurrence and abundance. Seasonal trends were synchronised across the eight species; their monthly catches peaked from March to May and were nearly zero in other months. An analysis of correlations between environmental changes and insect abundances suggested that short-term changes in rainfall affected the synchrony. 4. In contrast, fluctuations in abundances of five other scarabaeid species were unrelated to calendar seasons. In one of the five scarabaeids, which is a flower-visiting species, the patterns in population fluctuation strongly correlated with flowering changes. In the remaining four species, no correlations were observed between environmental changes and population fluctuation patterns. 5. While previous studies have demonstrated that aseasonal patterns in population fluctuations are common in various insect assemblages in Southeast Asian rainforests, we show that clear seasonality is prevalent for the phytophagous scarabaeid assemblage.

A revision is presented of the species in the genus Parastasia. All known species are described, 11 new species are established, the parameres of most species are figured, the taxonomic levels of several taxa are changed, and 21 new synonymies are proposed. For many taxa lectotypes are designated and many specimens bearing incorrect or dubious type labels are degraded to their true status. Some aspects of distribution and dispersal are shortly discussed. A tentative key and a check list are added.
