03FA8783FF98FF945CF0F9592ED7F145.taxon	diagnosis	Diagnosis. This species is possibly most similar to C. uncula Mey. Both species have paired spinelike projections from dorsolateral margins of segment IX and also a modified tergum VIII, with a mesal invagination and accompanying spines. The differences, however, are considerable. The armature of tergum VIII is especially distinctive in C. aculeata in that the dorsal margin has a distinctive pair of brushes composed of many spines bordering the mesal invagination; also, the apices of the resulting lobes each have a small tassel of spines. The shape of the inferior appendages is also quite different in the 2 species.	en	Blahnik, Roger J., Arefina-Armitage, I., J, Brian (2012): The Genus Chimarra Stephens (Trichoptera: Philopotamidae) in Vietnam.

03FA8783FF9AFF9A5CF0F9792DB7F7A5.taxon	diagnosis	Diagnosis. We are unsure about the closest affinity of this species, which has a general similarity to a number of species in the tsudai Group. It is most readily diagnosed by the distinctive, angled apicomesal projection on the dorsal margin of each inferior appendage. This projection is also evident in lateral view. Description. Forewing length (male) 6.2 mm. Color (in alcohol) yellowish-brown. Head relatively elongate (postocular parietal sclerite extended behind eye). Mesoscutellar setal wart pear-shaped, with usual anterior suture. Maxillary palps with 1 st segment very short, 2 nd segment moderately elongate (shorter than segment 3, longer than segment 4), 3 rd segment relatively elongate, slightly shorter than segment 5, 4 th segment short. Tarsi of males somewhat modified, tarsal claws moderately enlarged, asymmetric in length and curvature. Forewing with Rs strongly deflected (curved toward anal margin) and sinuously inflected before base of discal cell; veins at base of discal cell somewhat swollen, length of discal cell about 3 times width; r-m and m cross-veins hyaline (unpigmented), s not hyaline, s and r-m linearly aligned, m distinctly proximal; anal veins without apical fork (2 A and 3 A both apparently looped to 1 A). Hind wing with Sc and R 1 narrowly separated, not fused. Male genitalia: Segment VIII with sternum short, subtending ventral margin of segment IX; tergum widened dorsally, dorsal margin rounded, projecting, without distinct modifications, about twice length of sternum VIII. Segment IX unsclerotized dorsally, with distinct, short dorsolateral apodemes on anterior margin, anterior margin extending nearly linearly from apodemes, curved in ventral half to form strongly projecting ventral margin, anteroventral margin strongly convexly rounded (as viewed dorsally or ventrally); segment very short dorsally (anterior and posterior margins narrowly separated), posterior margin abruptly, angularly lengthened below preanal appendages; ventral process very short, subtriangular, broad basally, ventrally projecting. Tergum X with lateral lobes simple in structure, elongate, narrow, rounded apically, with numerous sensilla along dorsal, ventral, and apical margins; mesal lobes digitate, nearly uniform in width, apices acute, lobes strongly reclinate and posteriorly projecting, apices of lobes, as viewed dorsally, curved outward, each lobe with two small subapical sensilla. Preanal appendages short, rounded, somewhat constricted basally (knob-like). Inferior appendages relatively short, subquadrate, each with mesally curved process from posterodorsal margin; as viewed ventrally, with apicoventral margin rounded and dorsomesal process narrowing apically to form very distinct, acute, posteromesally angled process; extreme apex of process mesally incurved, resulting in apices of paired appendages being nearly proximate. Phallotheca moderate in length, tubular, with usual basal expansion. Endotheca short, membranous, apicomesally with moderately elongate, narrow spine-like projection, apparently formed of several closely apposed seta-like spines; apex also with pair of small, rounded, membranous lobes, each with numerous, minute, weakly-sclerotized spines.

03FA8783FF94FF985CF0FB992EB5F045.taxon	diagnosis	Diagnosis. Chimarra mina belongs to a subgroup of species in the tsudai Group characterized by having a distinctive lateral brush of very elongate setae on the inferior appendages. The subgroup includes C. crepidata Kimmins, C. haimuoi Malicky, C. lahuorum Chantaramongkol and Malicky, C. oreithyia Malicky, C. pontus Malicky, C. scopulifera Kimmins, C. semiramis Malicky, and C. suthepensis Chantaramongkol and Malicky. Species differ in details of the shape of the inferior appendages, especially the position and shape of the apicomesal projections, the shape of the lateral lobes of tergum X, and in the armature of the phallic apparatus. Distinctive characters of C. mina include apicomesal projections on the inferior appendages that are relatively narrow basally (and thus more distinctly awl-like than some others in this group), a short tergum X with a basolateral bulge, and endothecal spines that include a pair of clustered spines.	en	Blahnik, Roger J., Arefina-Armitage, I., J, Brian (2012): The Genus Chimarra Stephens (Trichoptera: Philopotamidae) in Vietnam.

This species has an apparent close similarity to both C. thaiorum Chantaramongkol and Malicky and C. atnia Malicky and Chantaramongkol, especially in the elongate inferior appendages and the curvature of these in ventral view. It differs from either species in that the apices of the appendages are more strongly bent in their apical half, as viewed laterally, and in the very prominent basomesal protuberance of the appendages. Additionally, the lateral lobes of tergum X are much shorter and the mesal lobe of tergum X has a very distinctive Y-shaped apicomesal sclerite.	en	Blahnik, Roger J., Arefina-Armitage, I., J, Brian (2012): The Genus Chimarra Stephens (Trichoptera: Philopotamidae) in Vietnam.

Among described species, Chimarra corneola is perhaps most similar to C. georgensis, sharing a number of similarities, including, especially, the divided, spine-like lateral lobes of tergum X; and, the shape of the phallotheca, which is very short and has its apex strongly deflexed, with a pair of spine-like apical projections. However, it differs in the details of the shape of the lateral lobes and inferior appendages. The minutely spined ventral division of the lateral lobe of tergum X is especially distinctive.	en	Blahnik, Roger J., Arefina-Armitage, I., J, Brian (2012): The Genus Chimarra Stephens (Trichoptera: Philopotamidae) in Vietnam.

03FA8783FF8BFF8B5CF0F8F92EE7F125.taxon	diagnosis	Diagnosis. This is a distinctive species, best diagnosed by the very short lateral lobes of tergum X, each of which has a digitate ventral projection, and also by the structure of the inferior appendages, which are ovate and each have two mesal cusps, best seen in caudal view. The species is interesting in having some plesiomorphic features that characterize the georgensis “ Group ”, including a forewing with unmodified Rs vein, hyaline and linearly aligned cross-veins, and anal veins without an apical fork. It also possesses the apomorphic fusion of the Sc and R 1 in the hind wing that characterizes species in the georgensis “ Group ”, but lacks the highly modified and shortened phallotheca found in the type species for the group. As discussed above, fusion of the Sc and R 1 in the hind wing seems to have occurred in a number of lineages (as for instance, in the minuta Group discussed above and in the subgenus Otarrha). The character occurs especially among smaller species.	en	Blahnik, Roger J., Arefina-Armitage, I., J, Brian (2012): The Genus Chimarra Stephens (Trichoptera: Philopotamidae) in Vietnam.
