The holotype and the only known specimen of Ropalidia crassa van der Vecht, 1941, have been lost (Kojima & Carpenter, 1997) and the identity of this species is yet uncertain. We have searched in vain for specimens that fit the description of R. crassa by van der Vecht (1941) among the many specimens in MZB and IUNH. Distribution record: Indonesian Archipelago: Sulawesi I.

Ropalidia variegata
No full textRopalidia variegata (Smith, 1852) Epipona variegata Smith, 1852: 48 Remarks. Kojima and van Achterberg (1997) recorded a single female specimen of R. variegata as “ Sulawesi: nr Luwuk, Bunga, c. 300 m: 1, MT–17, 1–14.xi.1989, C. v. Achterberg (RMNH)”. This is the only R. variegata specimen from Sulawesi I. and we have not found any other specimens of this species among many Ropalidia specimens collected in Sulawesi I. and deposited in MZB and IUNH. The current occurrence/establishment of this species in Sulawesi I. would need confirmation based on further intensive field research. Distribution record: Indonesian Archipelago: Sulawesi I., Timor I.; Indian subcontinent; southern parts of continental China; Indochina Peninsular (Kojima and van Achterberg, 1997; Kojima and Carpenter, 1997; Nugroho et al., 2011).Published as part of Handru, Alan, Nugroho, Hari, Saito-Morooka, Fuki, Ubaidillah, Rosichon & Kojima, Jun-Ichi, 2020, Eusocial wasp fauna of Sulawesi Island, the central island of Wallacea (Hymenoptera: Vespidae; Polistinae, Vespinae), pp. 541-559 in Zootaxa 4885 (4) on page 556, DOI: 10.11646/zootaxa.4885.4.5, http://zenodo.org/record/429694
Ropalidia jacobsoni
No full textRopalidia jacobsoni (du Buysson, 1908) Icaria jacobsoni du Buysson, 1908: 123 Remarks. Since the only two female specimens of this species have been recorded from Sulawesi I. by van der Vecht (1962) as “ R. variegata jacobsoni … Celebes: 2 Females, South Celebes, Dec. 1936, Indonesian collector (ML [= currently Naturalis (formerly Rijksmuseum van Natuurlijke Historie), Leiden])”, the present species has never been recorded and we have searched in vain specimens of this species from Sulawesi I. in the collection of MZB and IUNH. It may need further intensive field research to clarify whether R. jacobsoni had previously occurred or currently occurs in Sulawesi I. Distribution records: Indonesian Archipelago: Bangka I., Sumatra I., Java I., Sulawesi I.; Indian subcontinent; Indochina Peninsular (van der Vecht, 1962; Kojima et al., 2007).Published as part of Handru, Alan, Nugroho, Hari, Saito-Morooka, Fuki, Ubaidillah, Rosichon & Kojima, Jun-Ichi, 2020, Eusocial wasp fauna of Sulawesi Island, the central island of Wallacea (Hymenoptera: Vespidae; Polistinae, Vespinae), pp. 541-559 in Zootaxa 4885 (4) on page 552, DOI: 10.11646/zootaxa.4885.4.5, http://zenodo.org/record/429694
Ropalidia impetuosa

Remarks. As given under “ Distribution records ”, this species is distributed in the areas east of the HuxleyWallace line. In the areas west of this biogeographical line, R. fasciata (Fabricius, 1804), the species apparently most closely related to R. impetuosa, is distributed, and as far as is known the two species do not co-occur. The two species may be distinguished with certainty only in males.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
