Allanagrus orientalis Manickavasagam & Palanivel , sp. n.

( Figs 1–7 )

Type material. Holotype female ( EDAU, registration No. Mym 21/2017) on slide, dissected under four coverslips: INDIA, Tamil Nadu, Salem, Yercaud , 11°49′N 0 78°10′E, 1.ii.2016, S. Palanivel and M. Avinkumar, YPT, coffee plantation.

Paratypes (5 ♀ on slide, EDAU): INDIA . Tamil Nadu. Salem, Yercaud , 11°49′N 078°10′E, 7.x.2013, S. Palanivel, T. Krishnachaitanya and S. Suneelkumar, YPT, forest (1 ♀) ; Pattipadi, 21.iv.2014, 31.i.2016, 1.ii.2016, 11°49′N078°10′E, S. Palanivel, M. Ayyamperumal and M. Avinkumar, YPT, coffee plantation (4 ♀). One paratype deposited in NBAIR, Bangalore.

Diagnosis. Females are distinguished from A. montanus , the only other Indian species of Allanagrus , by the features given in Table 1. It is distinguished from other world species with similarly long fl1 and fl2, i.e. excluding A. occidentalis , as follows. From A. magniclava females by fl2 with 3 mps and ovipositor clearly exserted beyond apex of gaster (fl2 with 0 mps and ovipositor barely exserted in A. magniclava ); from A. mayeri by fl4 same length as fl6 and fl2 and fl3 with mps (fl4 distinctly longer and fl2 and fl3 without mps in A. mayeri ); from A. aurum by distinctly exserted ovipositor (barely exserted in A. aurum ); and from A. gladius by the ovipositor not exserted as far beyond apex of gaster (much further in A. gladius ), the fore wing more pointed apically and with a much larger area along posterior half of fore wing without microtrichia (fore wing more rounded apically and with microtrichia more uniformly distributed and present along posterior half in A. gladius ), and fl5 much longer than fl4 or fl6 (fl5 almost same length as fl4 and fl 6 in A. gladius ).

Description. Female (holotype). Body length 650 µm. Body golden yellow. Head light brown with eye and ocelli dark red. Antenna yellowish to dark brown; wings hyaline ( Fig. 1 ).

Head width 205 ( Fig. 2 ); mandible unidentate. Antenna ( Fig. 3 a, b) with scape 3.0× as long as wide, 1.8× as long as pedicel; fl1 0.5× as long as fl2; fl2 1.1× as long as fl3; fl4 0.5× as long as fl5; fl2, fl3 and fl5 each with 2 mps; fl6 1.2× as long as wide; clava almost 3.0× as long as wide, with 7 mps.

Mesosoma ( Fig. 6 ) 0.9× as long as metasoma. Fore wing ( Fig. 4 ) 5.9× as long as wide; longest marginal seta 0.8× wing width. Hind wing ( Fig. 5 ) 18.8× as long as wide; longest marginal seta 3.3× wing width.

Metasoma with ovipositor 1.8× metatibia length and its exserted part 0.35× metasoma length ( Fig. 7 ).

Antennal segment length/width: scape, 75/25 (paratype); pedicel, 40/25; fl1, 28/13; fl2, 50/18; fl3, 43/20; fl4, 25/18; fl5, 45/23; fl6, 25/20; clava, 128/43. Mesosoma (paratype), 385/205. Fore wing length/width, 745/125; longest marginal seta, 110; hind wing length/width, 565/30; longest marginal seta, 100; metasoma, 405/150; ovipositor, 468, exserted part 143; metatibia, 250.

Male. Unknown.

Etymology. The species is named after the zoogeographical region of the type locality.
