Bermilloides lumawigi Otto , new species

Fig. 4–5

Description. Female holotype: Length, 14.0 mm. Width, 5.5 mm. Body color uniformly dark brownblack ( Fig. 4 ).

Head: Densely rugose; subspherical; surface dullish; delicate, median carina extremely short, confined to the vertex; epistomal part of epicranium with delicate, short median carina eyes slightly protuberant.

Antennae: Filiform, reaching just beyond the pronotal hind angles; dark brown.

Pronotum: Dark brown-black, dullish with short, yellow erect setae; surfaces densely rugose; wider than long, with large sharp, hind angles; lateral sides arcuate; disc convex; base sinuous.

Scutellum: Dark brown-black, dull, wide, sparsely setose, with median carina, sub-triangular and distally rounded.

Elytron: Convex, elongate, gradually narrowed from humeri to apices; conjoined tightly at apex; somewhat dullish with short, yellow recumbent setae; dark brown-black; length 10.0 mm; width 2.75 mm at humeri; humeri striate; disc striate; interstices elevated, transversely rugose.

Legs: Femur and tibiae dark brown; tarsi dark brown and somewhat shiny; surfaces closely punctate to rugose, with short, yellow recumbent setae.

Venter ( Fig. 5 ): Somewhat shiny; dark brown-black; surface with elongate, yellow recumbent setae; rugose.

Variation. Two paratypes were examined. The single male paratype is smaller than the holotype, measuring 8.5 mm long. Antennae are longer, extending beyond the pronotal hind angles by three segments. Antennomeres III–VII are quadrate, while antennomeres VIII–X are longer than wide in the male paratype. Median carina is strongly indicated on the pronotum, but shorter on the head, confined to the vertex in the male specimen. The single female paratype is slightly smaller than the holotype, measuring 11.0 mm long. Exoskeletal structures are similar to the holotype, except for the presence of a median fovea above the base of the epistomal part of epicranium. A median carina is feebly indicated on the pronotum, but strong on the head, extending from vertex midway down the frons in the female paratype.

Type material. Holotype, female, with label data: “ MALAYSIA: SABAH:, (Borneo) Crocker, Range ; 14-VI-2005 ” / “ Bermillus , sp., Det. R.L. Otto, 2012” / “ HOLOTYPE:, Bermilloides , lumawigi, Otto, det. R. L. Otto, 2014 ” (♀ handwritten behind species name on label) [red printed label] . Holotype in FSCA .

Paratypes. 2, each with label data: 1, “ PHILIPPINES, MINDANAO, MASARA, COMPOSTELA, VAL- LEY, ii 2014, lg: I. LUMAWIG” ( AAC) ; 1, “ PHILIPPINES:, Mindanao, Panamokan, Bukidnon, May 2014, Ismael Lumawig ” ( GERP). Each paratype labeled: “ PARATYPE:, Bermilloides , lumawigi, Otto, Det. R.L. Otto, 2014 ” (either ♂ or ♀ handwritten behind species name on label) [yellow printed label] . Paratypes in AAC and GERP.

Distribution. The species is known from a single locality in Malaysia and two localities on Mindanao in the Philippines.

Biology. The type locality is an upper montane forested environment. Two Philippine specimens were taken in tropical montane forests and mountainous forests. Developmental stages remain unknown.

Etymology. The specific epithet is named in honor of my friend Ismael Lumawig from the Philippines.

Remarks. Adults of Bermilloides superficially resemble the Southeast Asian genus Bermillus , but differ in the structure of the antennae, being quadrate to longer than wide and filiform in Bermilliodes and wider than long in Bermillus . The antennal grooves are medially undefined in Bermilloides and well defined in Bermillus . Slender mandibles, as well as straight sex combs along with the length of the prothoracic tarsomere I in males, places the new genus in the tribe Anelastidini . Form and basally toothed tarsal claws will distinguish it from Anelastidius Du Val within the tribe Anelastidini .
