Fernandoschmidia amudita , new species

Fig. 17

This and the following new species can be separated most readily on characters of the inferior appendage and phallic apparatus. In F. amudita the apical forks of the inferior appendage are subequal while in F. aramaniya , new species, the dorsal fork is much shorter than the ventral. In F. a m u d i t a the parameres are very long and relatively straight while in F. aramaniya they are shorter and curved. The dorsal keel on the phallicata is much larger and wider in F. amudita and there is a subapical ventral spine-like projection on the phallicata not seen in F. aramaniya .

Adult. Length of forewing: male 6.5 mm (n=1). Color brown, with scattered small patches of white hairs and distinct white spots at arculus, stigma, and apical wing margin.

Male. Abdominal segment IX annular, setose, especially ventrally; in lateral view anterior and posterior margins parallel; tergum IX long; anterior margin with pair of small acrotergites; posterior extension of sternum IX short, 1/2 length of sternum, in ventral view divided into pair of widely separated digitate processes, apices subacute, in lateral view digitate, tapering to acute apex. Preanal appendage lanceolate, heavily setose, about as long as segment X, apex acute, slightly directed mesad. Inferior appendage with broad, compact basal region and narrow digitate apical region, ventrolateral corner of basal region with subtruncate, flangelike, sclerotized ridge (best seen in caudal view), apical region bifurcate apically, dorsal fork short, narrowly digitate, ventral fork long, narrow. Tergum X saddle-shaped, short, about 1/3 width of segment IX, in lateral view triangular, apex acute, dorsolaterally with pair of low, weakly developed protuberances, in dorsal view apex slightly emarginate. Phallic apparatus elongate; phallobase subspherical, only partially fused with phallicata; phallobase ventrolaterally with ridge-like flange articulating with dorsolateral corners of basal region of inferior appendages; phallicata gradually curved ventrad along its length, apex of phallicata bulbous, with subapical, spine-like projection and apicomesal membranes; dorsally with large, rounded, medial keel; parameres very long, heavily sclerotized, relatively straight, bearing numerous thick spines apically; phallotremal sclerite not discernable.

Female. Unknown.

Holotype male: INDIA: Assam (Kameng), Bhairabkunda, 3–4, 7.iii.1961, F. Schmid ( CNC).

Distribution. India.

Etymology. This Sanskrit name was used by Schmid. We could not find an exact translation, but as a part of some words it may pertain to happiness or joy. The epithet is to be regarded as a noun in apposition.
