COMMENTS

WESTWOOD (1859) described Necroscia sangarius based on material from Mt. Ophir, from Pulau Penang in Peninsular Malaysia and from Sarawak in Borneo. REDTENBACHER (1908) described Calvisia commutata and referred to Westwood’s illustration of the male from Penang as being the same species. BROCK (1995) synonymised C. commutata with sangarius and designated the female from Mt. Ophir as the lectotype. Although the species was recorded from Borneo on numerous occasions ( WESTWOOD, 1859; BRAGG, 2001; SEOW-CHOEN, 2016, 2019), these records are regarded as erroneous and SEOW-CHOEN (2021) excluded the species from the Bornean species list. The paralectotypes of C. sangarius originating from Sarawak are considerably different from the lectotype and were recently identified as Calvisia (Nigracalvisia) nirgoaxillaris GÜnther, 1943 ( SEOW-CHOEN, 2021)

The female examined by the authors from Ringlet in the Cameron Highlands agrees in every aspect with the lectotype. It has the head and body predominantly olive green; the pronotum has the anterior and posterior margins vivid yellow and a red spot medially on the metazona; the mesonotum has the anterior and posterior margins red; tegmina and costal region of hind wing have an olive green ground colour with black spots with sky blue inclusions; legs have the posterior portion of femora and base of tibiae coloured dark blue to almost black. However, the descriptions and illustrations provided by BROCK (1999) and SEOW-CHOEN (2005, 2017, 2021) show a predominantly light- to reddish brown insect, but the markings on pro- and mesonotum and the black spots with sky blue inclusions on the tegmina and costal region of hind wing agree with the lectotype. All records agree in general morphology.

More research needs to be done by examining more specimens from different localities. Molecular and in vivo studies should provide interesting insights on the relevance of colouration characters for species delimitation in the genus Calvisia .
