D i a g n o s i s: The genus Isoparis OPITZ was described in 2017 ( OPITZ 2017). In this work, I described Isoparis virgulata from which I. cassidilis specimens differ by showing a more oblong pronotum, more fully developed pronotal tubercles, and the visible abdominal sternites II-IV each show a pair of small bursae.
D e s c r i p t i o n: Size: Length 4.3 mm; width 1.0 mm. Form: As in Fig. 329 View Figs 326-329 . Color: Cranium and pronotum castaneous, pronotal disc with 3 black stripes; pterothorax brown; mesothorax, metathorax, and abdomen brown; elytra mostly castaneous, with yellow X-shaped marking; legs testaceous. Head: Eyes large, coarsely facetted, eye wider than frons (EW/FW 25/20); funicular antennomeres subfiliform ( Fig. 97 View Figs 92-100 ), capitular antennomeres 9 and 10 triangular, antennomere 11 narrow ovate. Thorax: Pronotum ( Fig. 170 View Figs 163-170 ) oblong, lateral tubercle well defined (PW/PL 65/74), disc coarsely punctate; elytral asetiferous punctures profusely distributed; (EL/EW 185/50). Abdomen: Pygidium quadrate / scutiform; aedeagus as in Fig. 246 View Figs 243-248 .
Variation: Length 4.0-5.0 mm; width 1.3-1.8 mm. Other than body size, the available specimens are quite homogeneous.
N a t u r a l H i s t o r y: The Bolivian specimens were collected during November, at 430 m.
D i s t r i b u t i o n: This species is known from Bolivia and Brazil.
E t y m o l o g y: The trivial name, cassidilis, is a Latin noun with a meaning of "small bag"; with reference to the small paralateral saccular structures on sternites II-IV.
