Diagnosis.

Phanuromyia ganga sp. nov. is close to P. kadamba sp. nov. but differs from it in the following character states. Posterior row of foveae on T1 ovoid, posterior margin of T2 straight; whereas in P. kadamba sp. nov. posterior row of foveae on T1 elongate, posterior margin of T2 convex and T3-T6 punctate.

Description.

Female body length=0.91-1.12 mm (n=5).

Colour. Head and mesosoma black; metasoma black-brown;radicle and A1-A7 yellow-brown, remaining antennomeres brown; procoxa brown, meso-and meta coxae yellow, remainder of legs yellow.

Head. Head 1.3 × as wide as high, 1.1 × as high as long; IOS 0.5 × head width, 0.9 × eye length; entire frons coriaceous reticulate, except for a smooth patch medially; transverse carinae present on either side of imaginary central keel; central keel absent; vertex transversely coriaceous reticulate; gena coriaceous reticulate except for smooth basal area with sparse transverse striae; eyes (L: W=13.2:10.8) large, without setae; POL: LOL in ratio of 8.2:3.9; lateral ocelli contiguous with orbits; hyperoccipital carina absent; occiput coriaceous reticulate with elongate setae; A1 3.2 × as long as wide; A1 2.6 × as long as A2.

Mesoscutum (L: W=16.1:22.1) convex, coriaceous reticulate, setose; mesoscutal humeral sulcus foveate; mesoscutal suprahumeral sulcus not foveate; lateral pronotal area posterodorsally transversely striate, anterodorsally weakly coriaceous reticulate, remainder smooth; epomial carina present; pronotal suprahumeral sulcus weakly foveate, setose; netrion sulcus entirely foveate; subacropleural sulcus indicated by two foveae; prespecular sulcus indicated with three foveae; mesopleural pit distinct; speculum transversely carinate; episternal sulcus indicated by foveae which continue along postacetabular sulcus; femoral depression weakly reticulate; ventral mesopleuron smooth with a weakly reticulate patch anteriorly; mesepimeral sulcus foveate; mesepimeral area smooth, narrower than width of mesepimeral sulcus; metapleural sulcus foveate; paracoxal sulcus foveate; dorsal and ventral metapleural area with intricate sculpture; metapleural epicoxal sulcus indicated by depressions; scutoscutellar sulcus laterally foveate; mesoscutellum semicircular (L: W=5.4:15.3), smooth; posterior mesoscutellar sulcus foveate; metascutellum anteriorly foveate, remainder weakly tuberculate with an uneven transverse furrow medially; metanotal trough weakly foveate; lateral propodeal area weakly sculptured, with foveae on inner margin; medial lateral propodeal carina not visible as hidden beneath metascutellum when viewed dorsally; fore wing (L: W=61.9:20.6) and hind wing (L: W=54.4:9.0) hyaline with dense microtrichia; ratio of length of marginalis: stigmalis: postmarginalis 5.4:7.4:12.9, respectively.

Metasoma. (L: W=35.1:20.6); T1 with basal foveae followed by a wide smooth patch and further by a band of longitudinal foveae; T1 laterally and posteriorly smooth; T2 smooth except for small basal foveae followed by weak longitudinal striae, extending 0.3 × length of tergite submedially; remaining tergites smooth; posterior margin of T2 straight; T1 with several lateral and one sublateral setae; T2 2 × length of T1.

Male. Not known.

Etymology.

This species is named after the Western Gangas, who came to power in the region of erstwhile Mysore after the reign of the emperor Ashoka Maurya.The name is treated as a noun in apposition.
