Diagnosis.

Phanuromyia nirvighna sp. nov. is close to P. kanva sp. nov. The distinguishing characters are given under the latter species.

Description.

Female body length=0.96-1.21 mm (n=3); male: body length=1.02 mm (n=1)

Colour. Head and mesosoma black; metasoma black-brown; radicle and A1 yellow-brown, A2-A4 brown, A5-A7 yellow, remaining antennomeres brown-black;procoxa brown-black, meso- and metacoxae brown-yellow, remainder of all legs yellow-brown.

Head. Head 1.3 × as wide as high, 1.3 × as high as long; IOS 0.5 × head width, subequal to eye length;frons entirely coriaceous reticulate except for a medial smooth patch, and sparse striae above toruli; central keel absent; vertex coriaceous reticulate;gena weakly reticulate, except for smooth patch ventrally; eye (L: W=12.7:10.7) large, densely setose, setae long; POL: LOL in ratio of 11.2:6.0; lateral ocelli contiguous with orbits; hyperoccipital carina absent; occiput coriaceous reticulate with elongate setae; A1 4 × as long as wide; A1 2.7 × as long as A2.

Mesosoma. Mesoscutum (L: W=17.1:21.3) not convex, coriaceous reticulate, setose; mesoscutal humeral sulcus not foveate; mesoscutal suprahumeral sulcus not foveate; lateral pronotal area coriaceous reticulate; epomial carina present; pronotal suprahumeral sulcus not foveate; netrion sulcus weakly foveate dorsally; pronotal cervical sulcus foveate; subacropleural sulcus with two foveae, ventral to which an oblique furrow extends towards mesopleural pit; prespecular sulcus not foveate; mesopleural pit distinct with several vertical striae ventrally; speculum with weak transverse carinae; episternal sulcus not foveate; postacetabular sulcus not foveate; femoral depression smooth; ventral mesopleuron smooth except for anterior reticulate patch; mesepimeral sulcus indicated by a blunt carina; mesepimeral area smooth, wider than width of mesepimeral sulcus; metapleural sulcus indicated by three foveae dorsally; paracoxal sulcus not foveate; dorsal metapleural area smooth to weakly tuberculate; ventral metapleuron smooth;metapleural epicoxal sulcus with weak depressions; scutoscutellar sulcus foveate laterally; mesoscutellum semicircular (L: W=5.6:12.0), smooth, setose; posterior mesoscutellar sulcus foveate; metascutellum with a weak projection posteromedially, with small foveae on anterior margin, remainder smooth to weakly tuberculate; metanotal trough not foveate; lateral propodeal area smooth with large depressions on inner margin; entire lateral propodeal carina visible posterior to metascutellum when viewed dorsally; fore wing (L: W=57.4:21.3) and hind wing (L: W=54.6:8.3) hyaline with dense microtrichia; ratio of length of marginalis: stigmalis: postmarginalis 6.4:8.9:15.1, respectively.

Metasoma. (L: W=33.4:21.2); T1 with longitudinal foveae, laterally and posteriorly smooth; T2 with large basal foveae, followed by longitudinal striae culminating in weak reticulations; remaining tergites smooth; posterior margin of T2 slightly convex; T1 with three lateral setae and one sublateral seta; T2 4.8 × the length of T1.

Male. Similar to female.

Etymology.

This species is named ‘nirvighna’, one of the numerous names of the Hindu God Ganesha. The name is treated as a noun in apposition.
