Brachinus stenoderus Andrewes, 1924 [non Bates, 1873] ( Lorenz 2016; Anichtchenko 2016)

Material examined. Gilgit-Baltistan, Hunza , Jaglot , 5 ♀ & 5 ♂, 09.ix.2014 ; Skardu, Rundu , 1 ♀ & 2 ♂, 04.ix.2014, Mishkat & Ibad ; Khyber Pakhtunkhwa, Chitral, Shah Sheri Sham , 1 ♀ & 2 ♂, 22.viii.2015, Mishkat ( PMNH).

Measurements. Male (n=5): TL= 10.61 mm, HW= 1.91 mm, PL= 1.81 mm, PW= 1.68 mm, EL= 6.68 mm, EW= 2.28 mm. Ratios PL/PW= 1.07, HW/PW= 1.13 and EL/EW= 2.92

Female (n=5): TL= 10.34 mm, HW= 1.78 mm, PL= 1.71 mm, PW= 1.59 mm, EL= 6.55 mm, EW= 2.15mm. Ratios PL/PW= 1.07, HW/PW= 1.11 and EL/EW= 3.04

Diagnosis. Mostly reddish yellow. Antenna, palps and legs pale yellow. Head and pronotum strikingly narrow, the head longer than wide with large eyes. Elytra black-blue with fine vigorously raised striae. Elytral membranous apical margin moderately developed and clothed with a fringe of closely spaced, very short setae. Abdomen ventral side blackish brown and thorax yellowish brown.

Comments. Brachinus pallidipes was placed in the subgenus Brachynolomus Reitter, 1919 ( Anichtchenko 2016; Lorenz 2016), while Hrdlička (2003) retained this species in incertae sedis. We suggest the placement of this species in the subgenus Neobrachinus , as the III antennal segment is longer than the combined length of I plus II segments (it is subequal in Brachynolomus ). Likewise, male anterior tarsal articles show ventral adhesive vestiture longitudinally arranged, as in Neobrachinus , whereas it is diagonally arranged in Brachynolomus .

Distribution. This species is newly recorded from Pakistan. It has been recorded from India by Anichtchenko (2016).
