Cavoptinus palawanicus nov.sp., a new species from the Philippines (Coleoptera, Bostrichoidea, Ptinidae)

Jiří HÁVA & Petr ZAHRADNÍK

A b s t r a c t : A third species Cavoptinus palawanicus nov.sp. belonging to the genus Cavoptinus PIC, 1931, (Cavoptinus albonotatus PIC, 1931 and Cavoptinus luzonicus ZAHRADNÍK & HÁVA, 2017) from the Philippines is described, illustrated and compared. K e y w o r d s : , new species, Coleoptera, Ptinidae, Ptininae, Cavoptinus, the Philippines.

Introduction

Until recently, the genus Cavoptinus PIC, 1931 contained two species from the Philippines: Mindanao I. and Luzon I. (BELLÉS 1983, 1991; ZAHRADNÍK & HÁVA 2014, 2017) – type species Cavoptinus albonotatus PIC, 1931. In this article we describe a new species from the Philippines: Palawan I. This genus is similar to Cylindroptinus PIC, 1910, Luzonoptinus PIC, 1923 and Maheoptinus PIC, 1903.

Material and methods

We have studied original descriptions of all three mentioned genera - Cavoptinus PIC, 1931, Cylindroptinus PIC, 1910, Luzonoptinus PIC, 1923 and Maheoptinus PIC, 1903 (including all four subgenera: Maheoptinus - Maheoptinus s. str., Cephaloptinus BELLÉS, 1983, Kalimantanus BELLÉS, 1991 and Luzonites BELLÉS, 1983). Specimen of the presently described species are provided with a red printed label with the text as follows: "HOLOTYPE Cavoptinus palawanicus nov.sp. J. Háva & P. Zahradník det. 2020".

Taxonomy Cavoptinus palawanicus nov.sp. (Figs 1a-d) Type material: Holotype (♂): Philippines, Palawan, San Vicente, October 2019, local collector. Holotype deposited in coll. J. Háva (Jiří Háva, Private Entomological Laboratory & Collection, Únětice u Prahy, Prague-West, Czech Republic). D e s c r i p t i o n : Male. Longly oval, slightly transversally convex, body length 3.2 mm, greatest width 1.2 mm (Fig. 1a). Piceous black, antennae, palpi and legs dark brown, brown setation erect and long, grey setation recumbent and short. 86

Head slightly convex, shiny, finely and densely punctuate, punctures almost touched, with intermixed grey and brown setation, on vertex sparser. Eyes relatively large, globular, glabrous. On front between eyes with a few long erect setae. Palpi dark brown. Antennae consist of eleven antennomeres, filiform, without antennal club (Fig. 1c). All antennomeres with dense, long semi-erect, brown setae. Pronotum slightly longitudinal (Fig. 1b). Sides of pronotum parallel (from dorsal view), in the middle slightly narrowed. Disc of pronotum with short, very narrow, longitudinal depression. The posterior part of pronotum with depression with long grey setae, posteriorly sharpened. Surface of pronotum shiny, finely punctuate. Part of surface covered with short grey setae (especially on border of depression) and with long dense erect, brown setae, especially on border of pronotum. Scutellum triangular, covered densely by grey setae. Elytra parallel, obtusely ended, with distinct shoulders, shiny, with long erect, brown setae and short grey setae. Each elytron with tenth striae consisting of large, longitudinal punctures. Interstriae narrower than striae. Each elytron with one humeral spots of grey setae and the posterior third quarter of grey setation. Legs dark brown, slim, covered with intermixed yellow and white setation, femur more robust. Tibiae as long as tarsi. All tarsomeres short and wide, slightly emarginate. Claws large, without teeth. Metasternum covered with grey setation, with longitudinal suture, inclined anteriorly from base (Fig. 2a). Male genitalia see Fig. 1d. Female: unknown. Differentialdiagnosis: The new species is similar to Cavoptinus albonotatus PIC, 1931 and C. luzonicus ZAHRADNÍK & HÁVA, 2017 but differs from them by the form of pronotal carinae, elytral spots and the structure of male genitalia. E t y m o l o g y : Named according to the type locality, Palawan Island, the Philippines.

Key of genera

Cavoptinus PIC, 1931 - Metasternum without suture (Fig. 2b) ...... Luzonoptinus PIC, 1923
