Agenysa stragula ( Boheman, 1862) comb. nov.

Mesomphalia stragula Boheman, 1862: 158 (original description).

Type locality. ‘Peruvia’.

Type material examined. HOLOTYPE: ♂, pinned, ‘ Peru [b, hw, s] || Type [w, p, s, c, rf] || Peru [hw] | Baly Coll. | 1905—54. [w, p, cb] || Mesomphalia | stragula | Boh | Peru [w, hw by Baly, cb] || Cuming | This species | was returned by | Boheman under | the name of | astulula Boh | is I believe | the type of | stragula | 34 [hw by Baly on underside of preceding label]’ ( BMNH).

Remarks. Mesomphalia stragula was unknown to subsequent authors, only SPAETH (1914) transferred it to Pseudomesomphalia (= Stolas ). Its holotype certainly belongs to Agenysa as it has a strongly widened last tarsomere. It is very similar to A. connectens as it has low convexity of elytra and reticulation nearly vanished on apical third of elytra but it differs in wider and trapezoidal pronotum with maximum width in apical third and more converging posterad than anterad while A. connectens has narrower and oval pronotum equally converging posterad and anterad. Agenysa stragula also has a black dorsum with dark metallic sheen and anterior part of explanate margin of elytra almost impunctate while A. connectens is bright metallic green or blue-green and has anterior part of the explanate margin finely but distinctly punctate. On the other hand, it is possible that A. stragula is only a local form of A. connectens but this requires further study based also on molecular data.

Distribution. Peru ( BOHEMAN 1862).
