Horniolus guimeti (Mulsant)

( Fig. 1e )

Scymnus guimeti Mulsant, 1850: 979 (lectotype female; OUMNH).– Weise 1879: 145; Korschefsky 1931: 143.

Horniolus guimeti: Booth & Pope 1989: 354 (lectotype designation).– Poorani 2002: 349; Chen et al. 2016: 119.

Distribution. Malaysia ( Sarawak and Sabah); Bangladesh.

Note. Horniolus guimeti (Mulsant) ( Fig. 1e , BMNH) was originally described by Mulsant (1850) as Scymnus guimeti based on Hope’s material. Booth & Pope (1989) mentioned that “this species appears not to have been correctly recognized since its original description”, transferred it to Horniolus and designated a lectotype for it with illustrations of the male and female genitalia. As observed by Poorani (2002, 2015), it is a doubtful record for India and the specimens identified as H. guimeti by R. D. Pope in the collections of the erstwhile Commonwealth Institute of Biological Control, Bangalore, were found to be Scymnus (Pullus) latemaculatus Motschulsky, 1858 , a common species with a superficially similar elytral pattern consisting of four yellow spots. Poorani (2002) and Chen et al. (2016) included Bangladesh in its distribution range and it remains an unverified record.
