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.
The specimens examined were collected from Luzon, Philippines. All materials were deposited at Australian National Insect Collection, CSIRO, Canberra, Australia (
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
Filipinolotis Miyatake, 1994: 254. Type species: Filipinolotis latefasciata Miyatake, 1994.
The genus Filipinolotis can be distinguished from other genera of the tribe Sticholotidini by the following characters: body rounded, glabrous, dorsum strongly convex (Figs

Filipinolotis latefasciata Miyatake, 1994: 255
This species can be recognized by the following combination of characters: pronotum reddish yellow, elytra blackish shiny with a broad transverse reddish yellow band in the middle (Figure
TL: 1.92–2.3 mm, TW: 1.86 mm, TH: 1.35–1.38 mm, TL/TW: 1.03–1.24; PL/PW: 0.38–0.42; EL/EW: 0.89–1.08; HW/TW: 0.39; PW/TW:0.67–0.74.
Head reddish yellow (Figure
Body rounded, dorsum strongly convex and glabrous (Figure
Male genitalia (Figure
Philippines: 1 male, Mt. Polis, Lepanto, Luzon Prov., Böttcherleg (
Philippines (Luzon).
This species is similar to F. latefasciata Miyatake but it can be distinguished from the latter as follows: body uniformly black with purple shine, without spots (Figure
TL: 1.99–2.63 mm, TW: 1.84–2.55 mm, TH: 1.28–1.8 mm, TL/TW: 1.03–1.08; PL/PW: 0.40–0.49; EL/EW: 0.93; HW/TW: 0.34–0.39; PW/TW: 0.59–0.60.
Color: Head, pronotum, scutellum, elytra purplish shiny black, without spots (Figure
Body rounded, dorsum strongly convex and glabrous (Figure
Male genitalia. Tegemen stout and symmetrical, tegminal strut stout and straight; penis guide in lateral view almost straight and gradually narrowing along apical third to pointed apex, with membranous prominence at basal half; in ventral view narrowest at base and gradually broadening to apex, then strongly narrowed to form a nipple-shaped apex; parameres with dense long setae apically, longer than penis guide; phallobase membranous (Figure
Holotype: Philippines: 1 male, La Trinidad, Luzon Prov., 1300m, 4–5.IV.1968, Benqae (
Philippines (Luzon).
The name purpuratorotunda is composed of the word purpuratus, which refers to the purplish color of the body and rotundus, referring to the rounded body shape.
