Eulichas pacholatkoi Jäch, 1995

( Figs. 26 , 42 , 63–64)

Eulichas pacholatkoi Jäch, 1995: 369 (original description, Vietnam: Da Lat: Phu Hua Hotel)

Type locality. “Phu Hoa Hotel, Da Lat City, 11°56’N / 108°25’E, 1500 m a.s.l. (collected at light)”.

Type material. Holotype ɗ ( NHMW), labelled: “S-VIETNAM / Dalat City / 21. – 27. 4. 1994 / Pacholatko & Dembicky [printed] // HOLOTYPE / Eulichas / pacholatkoi sp. n. / des. M. Jäch 1994 [red label, printed]”. Paratypes: 2ɗɗ 1Ψ, “S-VIETNAM 28.–30.4. / 12km N Dalat, 1994 / Lang Bian / Pacholatko & Dembicky [printed]” ( NHMW).

Additional material studied. 8 specimens — VIETNAM: 6ɗɗ, 12 km N Dalat [Ðà Lat], Lang Bian, 12°03’N 108°27’E, 1580–1750 m, 17.–21.iv.1995, P. Pacholátko & L. Dembický leg. ( NHMW). The following specimens were identified with doubt: 1ɗ 1Ψ, Vietnam, Gialai [Gia Lai, = Pleiku], Contum [Kon Tum], Tramlap, 20.iv.1995, Govochov leg. ( ZMAS).

Description. Habitus elongate, fusiform. Body colouring brown. Setation consists of dominant recumbent light brown setae covering most of dorsal surface, thus the colouration of the body seems to be paler than the colour of integument, and whitish setae forming ocellations on pronotum and elytra (Fig. 63). On abdominal sternites, whitish setae predominate over brown ones.

Measurements. Males: 25–26 mm; female: 30 mm.

Head punctation consists of sparse fine setigerous punctures. Antenna robust, last antennomere 1.71–2.05 times as long as wide ( Fig. 42 ), its ventral side smooth with numerous small tubercles.

Pronotum largely transverse, ca. 2.25–2.37 times as wide as long. Sides almost regularly rounded. The disc with two rounded shallow depressions. Punctation consists of fine and sparse setigerous punctures on the disc, which become slightly coarser and denser laterally.

Elytra with numerous longitudinal rows of moderately large setigerous punctures, and very fine interstitial 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 longer than parameres. Parameres simple, their subapical hook is reduced to an indistinct angle. Median lobe slender, subparallel ( Fig. 26 ).

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

Remarks. The two specimens from “Gia Lai – Kon Tum” agree with typical material in the shape of last antennal segment and male genitalia. However, they are more robust (male: 27 mm; female: 33 mm), and the body setation consists of dark brown and greyish setae forming ocellations (Fig. 64). While only two specimens are known to me, I have assigned them provisionally to E. pacholatkoi . Study of more extensive material may reveal that these specimens represent a separate taxon.

Collection circumstances. Collected at light.

Distribution. So far known only from several localities in southern Vietnam.
