Diagnosis.

This species can be easily identified with the narrow and elongate metasoma and T2, the latter with longitudinal striae extending 3/4 length of tergite.

Description.

Female body length=1.05-1.25 mm (n=2).

Colour. Head and mesosoma black; metasoma black-brown; radicle yellow, A1-A4 brown with weak yellow patches, A5-A7 yellow-brown, remaining antennomeres black-brown; procoxa black-brown, meso- and meta- coxae yellow; remainder of legs yellow-brown.

Head. Head 1.3 × as wide as high, 1.3 × as high as long; IOS 0.5 × head width, 0.8 × eye length; frons dorsally weakly reticulate, medially smooth, transversely carinate above toruli, remainder coriaceous reticulate; central keel absent; vertex coriaceous reticulate; gena coriaceous reticulate except for smooth basal patch; eye (L: W=16.7:15.0) large, with short setae; POL: LOL in ratio of 10.4:4.5; lateral ocelli contiguous with orbits; a blunt hyperoccipital carina indicated; occiput coriaceous reticulate with elongate setae; A1 3.6 × as long as wide; A1 2.7 × as long as A2.

Mesosoma. Mesoscutum (L: W=19.7:25.7) convex, coriaceous reticulate, setose; mesoscutal humeral sulcus foveate; mesoscutal suprahumeral sulcus not foveate; lateral pronotal area dorsally weakly coriaceous reticulate, remainder obliquely striate; epomial carina present; pronotal suprahumeral sulcus not foveate; netrion sulcus entirely foveate; subacropleural sulcus not foveate; prespecular sulcus with four foveae; mesopleural pit distinct with several carinae radiating ventrally; speculum with transverse carinae; episternal sulcus not foveate; postacetabular sulcus weakly foveate; femoral depression smooth; ventral mesopleuron smooth with anterior coriaceous reticulate patch; mesepimeral sulcus foveate; mesepimeral area smooth, narrower than width of mesepimeral sulcus; metapleural sulcus foveate; paracoxal sulcus indicated; dorsal metapleural area smooth; ventral metapleuron smooth with sparse, blunt oblique carinae; metapleural epicoxal sulcus indicated with depressions; scutoscutellar sulcus wide, foveate laterally; mesoscutellum semicircular (L: W=6.4:20.0), smooth; posterior mesoscutellar sulcus foveate; metascutellum foveate on anterior margin, remainder smooth; metanotal trough foveate; lateral propodeal area smooth with foveae on inner margin; entire lateral propodeal carina visible posterior to metascutellum when viewed dorsally; fore wing (L: W=70.3:24.3) and hind wing (L: W=64.9:9.6) hyaline with dense microtrichia; ratio of length of marginalis: stigmalis: postmarginalis 6.6:11.2:15.1, respectively.

Metasoma. (L: W=55.3:23.8); T1 with longitudinal foveae, laterally and posteriorly smooth; T2 with elongate basal foveae, followed by longitudinal striae, extending 0.8 × length of tergite; remaining tergites smooth; posterior margin of T2 slightly convex; T1 with two lateral and a sublateral setae; T2 4.2 × the length of T1.

Male. Not known.

Etymology.

The species is named after the ancient Chera kingdom located on the Malabar coast in southwest India. The name is treated as a noun in apposition.
