The genus Filipinolotis Miyatake has been reviewed in this study. Descriptions and illustrations of two species (F. latefasciata Miyatake and F. purpuratorotunda Wang, Zhang & Ślipiński, sp. n.) in the Luzon island of the Philippines, are given. The male genitalia of F. latefasciata are described for the first time. A key to known species is also provided.

The family Coccnellidae is an abundant species group of beetles. Ślipiński (2007) proposed a two subfamily system with Microweiseinae and Coccinellinae, merging Sticholotidini into an expanded concept of Coccinellinae (Escalona and Ślipiński 2012). The tribe Sticholotidini was defined by Gordon (1977) and Miyatake (1994). The final composition of Sticholotidini and the taxonomic status of many genera are not fully resolved (Ślipiński 2004). Coccinellid evolutionary history is borne out in previous molecular studies (Giorgi et al. 2009; Seago et al. 2011; Robertson et al. 2015).

Miyatake (1994) revised the Asian genera of the tribe Sticholotidini and proposed six new genera: Synonychimorpha, Chilocorellus, Sulcolotis, Filipinolotis, Mimoserangium, and Coelolotis for the species described from China, Philippines, and Vietnam. The genus Filipinolotis was erected with F. latefasciata Miyatake, 1994 as the type species from Luzon Island, Philippines. Filipinolotis is similar to Sticholotis except for some differences in characters of the hind wings (atrophied), antennae (shorter with distinct club), prosternal process (raised), and epipleura (broad). To date, F. latefasciata has been the only species in the genus Filipinolotis. In this paper, F. purpuratorotunda, sp. n. from Luzon Island in the Philippines is described and added to this genus.

Materials and methods

The specimens examined were collected from Luzon, Philippines. All materials were deposited at Australian National Insect Collection, CSIRO, Canberra, Australia (ANIC), South China Agricultural University, Guangzhou, China (SCAU), and Museum für Naturkunde in Berlin, Germany (MNB). External morphology was observed with a dissecting stereoscope (Zeiss Stemi 2000-cs). The following measurements were made with an ocular micrometer:

TL total length, length from apical margin of clypeus to apex of elytra;

TW=EW total width, width across both elytra at widest part;

TH height, from the highest part of the beetle to elytral outer margins;

HW head width in a frontal view, widest part including eyes;

PL pronotal length, from the middle of anterior margin to the base of pronotum;

PW pronotal width at widest part;

EL elytral length, along the suture, from the apex to the base including the scutellum.

Images were taken with digital cameras (AxioCam HRc and Coolsnap-Procf & CRI Micro*Color) connected to a dissecting microscope in the Key Laboratory of Bio-Pesticide Innovation and Application, Engineering Technology Research Center of Agricultural Pest Biocontrol, Guangdong Province of South China. The software AxioVision Rel. 4.8 and Image-Pro Plus 5.1 were used to capture images from the cameras. Software Adobe Photoshop CC 2015 was used for cleaning up images.

Terminology follows Ślipiński (2007) and Ślipiński and Tomaszewska (2010). Type specimens designated in the present paper are deposited at ANIC and SCAU.
