Macaranga glandibracteolata
No full textglandibracteolata, M. hullettii, M. indistincta, M. petanostyla, M. trachyphylla, M. umbrosa, the non-waxy form of M. aetheadenia, and the thinly wax-covered M. glandibracteolata as an exception of a glaucous host species). Queens colonize seedlings as well as the tips of mature hosts that have been abandoned due to the loss of the original colony. On Peninsula Malaysia secondarily polygynous colonies that contained several queens have been found locally in the Gombak area. In former publications by our group this species was referred to as Crematogaster msp. 4 (Fiala et al., 1999; Feldhaar et al., 2003a; Feldhaar et al., 2003b).Published as part of Heike Feldhaar, Ulrich Maschwitz & Brigitte Fiala, 2016, Taxonomic Revision of the Obligate Plant-Ants of the Genus Crematogaster Lund (Hymenoptera: Formicidae: Myrmicinae), Associated with Macaranga Thouars (Euphorbiaceae) on Borneo and the Malay Peninsula, pp. 651-681 in Sociobiology 63 (1) on page 670, DOI: 10.13102/sociobiology.v63i1.949, http://zenodo.org/record/26981

Crematogaster
No full textSynonymic list of Crematogaster ( Crematogaster borneensis - group ) species from Borneo and the Malay Peninsula obligately associated with Macaranga In this study eight species of Crematogaster (Crematogaster borneensis -group) are recognized (including five new species), belonging to three species subgroups. Species subgroups were designated based on morphological characters of the queen caste, i.e. queens of the decamera -subgroup are smaller (WL ranging from 1.7 to 2.3 mm) and have relatively smaller compound eyes (EL 0.5 mm) (Feldhaar et al., 2003a; Feldhaar et al., 2010) (see Table S.1 for comparison of morphospecies designations used by our group and synonymized or new species names). All workers of Crematogaster (Crematogaster borneensis - group) workers including those associated with Macaranga have ten antennal segments. The workers of the Macaranga - associated Crematogaster species are all monomorphic. This is in contrast to the other three described species belonging to the former Decacrema from SE-Asia (C. angulosa, C. biformis and C. cephalotes) that all have dimorphic workers (see Supplementary Fig S2.1A to S2.3B). Body size may vary strongly within species although this is dependent on colony size (e.g. TL ranges from ~ 2.1 mm to 3.3 mm in Crematogaster captiosa workers). Thus, especially in workers relative measures (e.g. SI or RLEG) are more important characters than absolute measurements (e.g. SL or LHT) (see overview of most important distinguishing characters of workers in Table 1). Workers collected from small colonies are also lighter in colour. In queens shade of body coloration is a useful character, as are absolute measures. If possible, queens should be used for determination as worker characteristics are sometimes less distinctive (see overview of most important characters distinguishing queens in Table 1). Most of the diversity of the species is apportioned between the decamera -subgroup and the captiosa -subgroup. The placement of C. maryatii is unclear. In the molecular phylogeny based on mitochondrial DNA this species does not cluster with either group and came out most basal. Based on nuclear DNA (elongation factor 1α) (Feldhaar et al., 2010) this species is not separated from species of the captiosa -group. However, queen morphology and life-history characters resemble that of the decamera -group. Small size of queens and workers and early onset of reproduction may be a convergent trait though as this seems to enable usage of less productive and slow growing host plants (Feldhaar et al. 2010). Therefore, we currently do not place C. maryatii in either group. Crematogaster maryatii sp. nov. C. decamera -subgroup Crematogaster decamera Forel, 1910 Crematogaster hullettii sp. nov.
