Figures 97–102  
 Diagnosis: Cyrnopsis tangaron, new species, is distinguished from C. palpalis in having forewings each with very short apical fork 3 and stalked and short apical fork 4; crossvein m -cu is located more apically in each forewing, resulting in a sessile apical fork 5; and in the hind wings each having a sessile fork of M1+2 and M2+3. The male genitalia are similar to those of C. pingensis and C. hittigegamus. Cyrnopsis tangaron is distinguished from C. hittigegamus and C. pingensis by the shorter sternite IX and tergite IX being longer than the underlying segment X, not shorter as in the C. pingensis and C. hittigegamus. In addition, the cerci are more elongate, and less rounded. The gonopods of C. tangaron are broad basally, narrowing apically, and slightly sigmoid-shaped in lateral view; while in Cp. pigensis the gonopods are parallel-sided and straight in lateral view and in C. hittigegamus the gonopods have a bulbous base and are parallel-sided distally in lateral view.   
 Description: Male. Body uniformly pale brown. Maxillary palp formula (I,II)-IV-III-V. Head (Fig. 97) with well-developed epicranial grooves composed of coronal and frontal grooves, pair of elongate occipital compact setal warts dominating on dorsum of head; pair of postgenal and vertexal ocellar compact setose warts small; separation of frontal and antennal warts indistinct. Wings: venation as in Fig. 98; forewing length 2.8 mm.   
Male genitalia (Fig. 99–102). Sternite IX and tergite IX well-developed; sternite IX almost quadrate; tergite IX with short, tall, lateral regions supporting cerci and shallow, elongate, dorsomesal region completely covering segment X from above in lateral view (Fig. 99); tergite IX conical in dorsal view (Fig. 100). Intersegmental depresseion between tergum IX and segment X absent. Segment X membranous, shorter than elongated region of tergite IX and located below it.. Cerci as long as segment X in lateral and dorsal views (Figs. 99, 100). Sclerous paraproctal strap attached to ventrolateral margins of fused tergite IX and segment X; each strap originating at base of its cercus, running down to its posterodorsal corner of sternite IX before turning posteromesad into subphallic stripe. Gonopods each without harpago, elongate, much longer than segment X (Fig. 99); slightly S-shaped, broad at base; narrowing apically in lateral and ventral views (Figs. 99, 101); each curving slightly mesad along its length in ventral view (Fig. 101). Phallic apparatus embranced ventrally by subphallic sclerous straps of paraprocts and, together with segment X, forming almost closed sheath around phallic apparatus. Phallic apparatus (Fig. 102) tube-shaped, slightly arching posteroventrad; located dorsally in genitalia; phallotheca tube-shaped, retracted apical membranes without distinct spines or sclerites.  
 Holotype male: INDONESIA: East Borneo, Tangaron, [no date, Mjöberg] (NHRS).   
 Distribution: Indonesia (Borneo).   
 Etymology: Tangaron, named after the type locality.   
 Remark: Cyrnopsis palpalis Martynov is only known from female material.
