Pandher, Manpreet Singh & Saini, Malkiat Singh, 2012, Seven new species of the genus Chimarra Stephens (Trichoptera: Philopotamidae) from India, Zootaxa 3478, pp. 313-329 : 319-320

Chimarra lakhwinderae sp. nov.

( Figs. 10–13 , 29–31 , 46–47 )

Diagnosis: The male genitalia of this species closely resemble those of Chimarra burmana Kimmins 1957 from Myanmar but can be distinguished in lateral view by inferior appendages that are broad and curved inward, each with a distinct mesal process at its middle, whereas these appendages are pointed and without any mesal process in C. burmana . Also in lateral view, the apices of the lateral lobes of tergum X are rounded in C. lakhwinderae , but are triangularly pointed in C. burmana .

Description (male only): Length of each forewing 6.25 mm (n=2). Color in alcohol nearly uniformly fuscous except head blackish and femora yellowish grey; body covered with inconspicuous and fuscous pubescence. Each antenna 4.22 mm long (n=2). Maxillary palps 1.62 mm long (n=2), segment 3 sub-equal to 2 and 5; labial palps 0.65 mm long (n=2). Forewing venation: Rs deflected or curved; discoidal cell elongate, length 3 or more times width; crossvein m usually proximal to crossveins s and r-m; 2A obsolete apically and looped to 1A ( Figs. 46, 47 ).

Male genitalia ( Figs. 10–13 , 29–31 ): Abdominal segment IX long; in lateral view with anteroventral margin broadly pointed; posteroventral process scarcely evident; posterolatersal margins each with 2 protuberances, one each above and below articulation with inferior appendage. Inferior appendages in lateral view narrower basally and broader subapically, stout, each with distinct, backward-directed and incurved dorsomesal projection. Tergum X with sclerotized and projecting and paired lateral and mesal lobes; lateral lobes broad, rounded apically in lateral view; mesal lobes longer than lateral lobes, digitate in lateral view, outwardly curved apically. Preanal appendages rounded, wart-like laterally. Phallic apparatus with sclerotized portion long, cylindrical and pointed apically in ventral and dorsal views ( Figs. 30–31 ); phallobase cylindrical, posterior part of phallotheca with weak ventrolateral constriction in ventral view ( Fig. 29 ); phallotremal sclerite complex with 2 small slender Y-shaped processes facing each other in ventral view inside retracted phallotheca; endotheca without micro spines in retracted phallotheca, 4 broad, ovoid, asymmetrical spines beyond phallotremal sclerite complex in retracted phallotheca.

Female: Not known.
