Figs 40 A, 41; Map 6

Type material (1 ♂). Holotype, ♂, labeled ‘W. Malaysia: Pahang, Genting Highlands, Awana, 1150 m , 03.iv.1993, Löbl & Calame, #27a / Holotype [red], ♂, Horniella awana sp. n., det. Yin & Li, 2014, MHNG’.

Description. Male (Fig. 40 A). Length 3.26 mm. Head slightly longer than wide, HL 0.63 mm, HW 0.58 mm; anterolateral genal projections (Fig. 41 C) weakly indicated; median sulcus between antennal tubercles short; scapes (Fig. 41 B) lacking expansion at lateral margins; clubs (Fig. 41 A) formed by apical three moderately enlarged antennomeres; venter lacking lateral spines (Fig. 41 D). Maxillary palpomeres II slightly broadened from base toward apex. Each eye composed of about 40 facets. Pronotum longer than wide, PL 0.69 mm, PW 0.60 mm. Elytra wider than long, EL 0.83 mm, EW 1.25 mm; discal striae reaching apical 3/4 of elytral length. Protrochanters simple, profemora (Fig. 41 E) each with two tiny ventral denticles at base, protibiae (Fig. 41 F), mesotrochanters, mesofemora (Fig. 41 G), and mesotibiae (Fig. 41 H) simple; tarsomeres II normal, not extending to beneath tarsomeres III. Abdomen large, AL 1.11 mm, AW 1.30 mm, tergite IV (first visible tergite) with median carina extending pass half of tergal length, lacking lateral discal carinae, tergite V with thin median carina extending to apical 1/3 of tergal length. Sternite IX (Fig. 41 I) elongate, well-sclerotized. AeL 0.71 mm; aedeagus (Figs 41 J–L) with relatively stout, symmetric median lobe, apex obliquely and broadly rounded; endophallus composed of large, oval membranous part with many small denticles anterior to middle.

Female. Unknown.

Differential diagnosis. This species is placed as a member of the H. hirtella group. Males are similar to H. philippina and H. cibodas in general appearance as is discussed above. Horniella awana can be readily separated from these two species by its stout aedeagal form, which are distinctly elongate in both H. philippina and H. cibodas .

Distribution. West Malaysia: Pahang (Map 6).

Collection notes. The male was probably collected from litter samples by sifting and use of Winkler-Moczarski extractors, with this being the same procedure used by I. Löbl in Nepal and Thailand.

Etymology. This species is named after the type locality Awana .
