Fig. 2

Material examined. Holotype (female): Peninsular Malaysia, Pahang, Gunung Berembau, elev. 1433 m, coll. A. Harmann, 12 November 1980 ( BMNH).

Paratype: Peninsular Malaysia, Pahang, Bukit Fraser: 1 female, along Semantan Road, N03.71851, E101.74084, elev. 1289± 4.9 m, tall grasses, coll. M. K. Tan & S. T. Toh, 16 May 2013, 2021 hours ( ZRC).

Diagnosis. The new species differs from all other species of the genus except Lichnofugia nigra Ingrisch, 1998 by the black instead of orange red face and the shape of the female subgenital plate. From L. nigra , of which only the male is known, it differs by a wider expansion of the black colouration of the face and especially by a distinctly narrower face with in frontal view straight lateral margins, while in L. nigra the face is oval and clearly wider.

Description. Habitus of female as shown in Figs. 2 A–B. Frons rugose ( Fig. 2 C). Pronotum mat; anterior margin faintly concave in middle; posterior margin distinctly concave; transverse furrows obsolete. Paranota low; ventral margin little sinuate; posterior angle triangularly rounded; auditory swelling small, nearly circular, distinct; humeral sinus indicated. Prosternum mute; mesosternal lobes obtuse-angular; metasternal lobes rounded; intermedial plate with small obtuse cones at hind angles ( Fig. 2 D). Femora with the following number of spines on ventral margins: profemur 2 external 3 internal; mesofemur 4 external, 0 internal; postfemur 8-9 external, 0 internal. Knees lobes: profemur obtuse externally, acute internally; mesofemur obtuse externally, spinose internally; postfemur spinose on both sides.

Female. Tegmen reaching middle of metanotum. Hind wings reduced to (hardly visible) minute scales. Tenth abdominal tergite much shorter than preceding tergites; little obtuse-angularly excised in middle ( Fig. 2 E). Epiproct triangularly rounded with faint pit on dorsal surface. Cerci conical, apex pointing. Subgenital plate with lateral areas curved up, otherwise flat; apex roundly excised ( Figs. 2 F–G).

Colouration. Brown. Frons including ventral areas of fastigium verticis, of scapus and of eyes black; clypeus and labrum brown; mandibles black. Pronotum light brown with irregular blackish brown lateral bands, which are present as distinct spots at anterior and posterior margins, interrupted and partly dissolved in between. Tegmen dark brown with light veins. Abdomen brown with blackish brown lateral bands including light bubbles.

Measurements (2 females). See Table 2 .

Etymology. The species is named after Malaya , the old name for the type locality Peninsular Malaysia; noun in apposition. This species is the first species of Lichnofugia to be described from Peninsular Malaysia.
