Eulichas fasciolata

Hájek, Jiří, 2009, Revision of the genus Eulichas Jacobson, 1913 (Coleoptera: Eulichadidae) II. E. dudgeoni species group, Zootaxa 2192, pp. 1-44 : 36-38

The Eulichas fasciolata species complex

The complex contains four species from the Greater Sunda Island of Borneo. They differ from all other Eulichas species in the relatively short parallel sided parameres with a characteristic twisted apex. The subapical parameral hook is well developed, the subbasal hook is reduced. The median lobe is narrowly lanceolate, always longer than the parameres. The phallobase is about the same length as parameres and median lobe combined.

Description. Habitus elongate, fusiform. Body colouring redish-brown to brown. Pale part of setation consists of recumbent brownish-yellow setae covering uniformly head, pronotum and ventral part, and forming rather indistinct ocellations on elytra ( Fig. 21 ).

Measurements. Males: 23–32 mm; females: 30–35 mm.

Head punctation consists of sparse moderately large setigerous punctures. Antenna long, slender, last antennomere narrowly oval, 3.19–3.58 times as long as wide ( Fig. 41 ), its ventral side smooth.

Pronotum trapezoidal, ca. 1.90–1.91 times as wide as long. Sides almost straight, in some specimens with indistinct sinuation behind the middle, hind angles prominent ( Fig. 61 ). The disc convex with two lateral and one basal shallow depression. Punctation consists of sparse moderately coarse setigerous punctures on the disc, which become slightly coarser and denser laterally.

Elytra with numerous longitudinal rows of moderately large punctures, and 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 parallel sided, with twisted emarginated apex; their distal part rather short. Median lobe lanceolate, with thin apical part; exceeding parameres ( Fig. 81 ).

Female. Similar to male in habitus, but larger. Antenna shorter, and more slender.

Remarks. Although the type material of the species was not found/recognised in the MNHN, the large number of additional specimens from Kinabalu deposited in various collections has allowed confident identification and redescription of the species.

Collection circumstances. Collected at light in the primary forest.

Distribution. Known from the Malay part of the Greater Sunda Island of Borneo – Sabah and Sarawak.
