Afidentula manderstjerane bhutani ssp. nov.

( Figs. 47–56 , 172 )

Diagnosis. Differs from the nominotypical form in having median tooth of mandible provided with a few very small denticles and the pronotum without black macula, but can be identified without a doubt only by comparison of the male genitalia ( Figs. 49–52 ).

Description. Length 3.68 mm; TL/EW = 1.24; PL/PW = 0.42; EL/EW = 1.04; EW/PW = 1.64.

Pronotum light brown, darker medially; each elytron with six small brown spots arranged as 2–3–1, with apical spot weakly transverse. Meso and metaventrite brown. Abdomen light brown.

Antenna with antennomere 3 longer than antennomeres 4–6 together; antennomere 4 subquadrate, antennomere 5 longer than wide and longer than 4; antennomeres 6 and 7 subquadrate and 8 transverse. Mandibles three-dentate; median tooth with a few additional very small denticles.

Prosternal process ( Fig. 47 ) subtruncate apically; about 1.65 times wider than prosternum in front of procoxae in narrowest place. Metaventrite ( Fig. 47 ) without distinct groove behind raised border of intercoxal process.

Abdomen and male abdominal ventrite 6, and tergite VIII as in Figs. 48, 53, 54 .

Male terminalia and genitalia ( Figs. 49–52, 55, 56 ). Tergite IX not divided dorsally. Apodeme of sternite IX long and thin, about 2.5 times as long as width of tergite X. Tergite X arcuate at apex. Penis guide in lateral view broadest along basal third, apical ½ distinctly narrower, apex pointed and slightly curved outwardly; parameres shorter than penis guide. Penis thin with apical part submembranous, curved outwardly, somewhat pointed.

Female not known.

Type material. Holotype, male: “ Bhutan: Samchi, 300 m, 7-11.5., Nat.-Hist. Museum Basel—Bhutan Expedition 1972/ Afidentula manderstjernae (Muls.) det. R. Bielawski 1978” (MIZ).
