Eulichas incisicollis Pic, 1933

( Figs. 11–12 , 33 , 53 , 73 )

Eulichas incisicollis Pic, 1933: 22 (original description, Archipel Malais); Jäch 1995: 363 (catalogue); Ivie & Jäch 2002: 166 (correction of the type locality).

Type locality. “Archipel Malais: Isle” [“Camerons Island”, = Cameron Highlands, Malaysia].

Type material. Lectotype Ƥ ( BMNH), by present designation: “ Type [printed, round label with red frame] // Pres. by / Imp.Inst.Ent. / Brit. Mus. / 1932-412 [printed] // G. 837 [handwritten vertically along the left side of the label] / Malaya [printed] / Camerons / Island. / 2.4.1930 [handwritten] / Entom. Div. / Agric. Dept. [printed] // Eulichas / incisicollis / n sp / (desiré) [Pic’s handwriten] // LECTOTYPE / EULICHAS (s. str.) / incisicollis Pic, 1933 / Jiří Hájek det. 2009 [printed, red label]”. Number of syntypes unknown. I designate a lectotype to fix the identity of this species. There are several other species of Eulichas occurring in Cameron Highlands, and available taxonomic works do not allow an unambiguous identification of specimens.

Description. Habitus elongate, fusiform. Body colouring from brownish-red to brown. Pale part of setation consists of recumbent yellow or whitish setae forming indistinct ocellations on pronotum, and very characteristic ocellations on elytra ( Fig. 11–12 ).

Measurements. Males: 21–28 mm; females: 33–37 mm.

Head punctation consists of sparse, irregularly distributed moderately large setigerous punctures. Antenna slender, short compared to other species – reaching only the middle of body length. Last antennomere narrowly oval, 2.70–3.15 times as long as wide ( Fig. 33 ), its ventral side smooth.

Pronotum trapezoidal, ca. 1.95–2.11 times as wide as long. Sides skewed and straight in anterior two thirds, then with obtuse angle, distinct incision subbasally, and prominent hind angles ( Fig. 53 ). Pronotum with two rounded shallow depressions on the disc, and indistinct depressions medially also along anterior and posterior margin. Punctation consists of sparse regularly distributed setigerous punctures.

Elytra with numerous longitudinal rows of moderately large punctures, and very fine interstitial setigerous punctures.

Ventral part with fine punctures, which are sparse medially and become larger and denser laterally. Last abdominal ventrite laterally regularly rounded to apex.

Male. Aedeagus with phallobase shorter than parameres. Parameres simple, slender, their inner side attenuating regularly to subapical hook. Parameral subbasal hook is missing, but the subapical hook is developed. Median lobe slender, rather subparallel ( Fig. 73 ).

Female. Distinctly larger than male. Antenna shorter, and more slender. Lateral incision of pronotum more distinct.

Collection circumstances. Collected at light.

Distribution. So far known only from the Cameron Highlands on the Malay Peninsula.
