Cyphochilus carinchebanus Brenske, 1903: 381

Type material examined: holotype: ZMHB; 1 ♀; Carin Cheba, 800-1100 m, L. Fea V XII-88.

Material examined: 10 specimens.

MYANMAR: ZMHB; 1 ♂; Carin Cheba, 800-1100 m, L. Fea V XII-88; (Fig. 82).

THAILAND: MHNG; 2 ♂, 7 ♀; North Thailand, Chiang Rai, Wiang Pa Pao; 3.III.1988; leg. F. Ferrero.

Description of male specimen in ZMHB: Size – BL: 18.2 mm, BW: 7.1 mm, BWX: 9.3 mm, situated at midpoint of elytra. Color – Integument brown with legs, antenna and other appendices light brown; surface with white scales densely aggregated along the sides of pronotum and margins of elytra. Head – CW/L: 3.2; clypeus largely rounded (F/O: 4.9) with lateral margins divergent posteriad; antennal club much longer than antennomeres 2-7 (A2-7/CL: 0.7). Pronotum – (PnW/L: 2.2); apical angles and lateral margins flattened; apical angles right and slightly protuberant; basal lateral margins straight, basal angles obtuse. Elytra – Without any visible striae. Thoracic sterna – Surface with short, white pubescence and scales; mesosternum feebly developed (MstL: 0.35 mm) however visible in lateral view between the mesocoxae. Abdomen – Sternites with uniformly sparse scales; pygidium convex with the apical margin narrowly reflected. Legs – Protibia tridentate with the basal tooth well developed; slender apical tooth as long as the middle tooth. Aedeagus – Parameres slightly asymmetric with two long appendices in addition to the terminal part of parameres (Figs 47-49).

Variability: BL: 16.5-18.5 mm.

Females: Relatively larger than males (7.4-7.6 mm); antennal club ovate, much shorter than preceding antennomeres 2-7 (A2-7/CL: 2).

Type locality: The type locality Carin Cheba corresponds nowadays to Karen Hills (750 m altitude) in Myanmar.

Distribution: The species was described from Karen Hills in Myanmar, one of the main hill ranges in eastern Burma located across the SW corner of Shan State and Kayah State; is also known from the southwestern most district of Chiang Rai Province in northern Thailand.

Remarks: This is a small Cyphochilus species and can be readily separated from all other congeners by the unique form of the parameres. Unfortunately, Brenske described this species from a female specimen, however, comparison of recently collected specimens with the type, leave no doubt they are conspecific.
