Quercivir dohrni Lameere, 1912

( Figures 17–20 )

Quercivir dohrni Lameere, 1912: 37 ; Monné, 2018c: 137 (cat.).

According to Lameere (1912) (translated): “A female from Rio was sent to me by Dr. H. Dohrn of Stettin. The insect had been seen by Lacordaire, who had considered it as belonging to a new genus.”

In the ZMPA there is a specimen with the following labels ( Fig. 20 ):

1. White (handwritten): Quercivir / Lacordairei / Type / Lam.

2. Red (printed): Type

3. Greenish (handwritten): Rio / [unreadable]

4. White (printed): Mus. Zool. Polonicum / Warzawa / 12/45

5. White (printed): 400

6. Yellowish (handwritten): N. G. / Lacordaire

The first label was undoubtedly written by Lameere. This can be confirmed in the calligraphy examples in Horn & Kahle (1935: Plate III), and also in several other labels handwritten by Lameere. Based on a similar label from former Carl August Dohrn collection, the unreadable text on label “3” is the name of the collector. The informa- tion “12/45” on label “4”, is probably the date of the inclusion of the specimen in the ZMPA collection. Finally, the calligraphy on label “6” is not that of Lacordaire, as it is possible to see in the label of the Fig. 21 , and appar- ently is by H. Dohrn. Based on this evidence, we are sure that the specimen named “ Quercivir lacordairei ” in the ZMPA collection is the holotype of Quercivir dohrni . We infer that Lameere initially intended to name the species as “ lacordairei ”, put the label and sent the specimen to H. Dohrn. However, he changed the name to “ dohrni ” in the publication. As additional confirmation of the identity of the holotype of Q. dohrni , the length of the specimen (about 32 mm) matches the measurement in the original description (34 mm).

According to Lameere (1912) (translated): “The generic name of Quercivir was given to him in litteris by Dr. Dohrn father… the color is light reddish brown with the elytra testaceous; the prosternum is covered with abundant yellow setae. The eyes are very widely separated dorsally and ventrally, the upper eye lobes do not surpass the level of the inner base of the antennal tubercle. The antennae only reach the middle of the elytra; they have a poriferous space limited by a carina from internal end of the antennomere III, and the four last antennomeres are completely poriferous, the carina of the antennomeres VIII-X is median; the antennomere III one-third longer than IV, the remaining decreasing in length, XI just longer than X; the apex of the antennomeres is projected from III, but it is not angular, and progressively so from V; the scape is rugose-punctate, the antennomere III coarsely and sparsely punctate. The head and prothorax are very rugose; the lateral margins of the prothorax are angular near anterolateral angles, and then directed a little obliquely to a relatively strong medial tooth, raised upwards; from this tooth, the margins are nearly straight directed toward posterolateral angle, which is well-marked in a right angle; the posterior margin is distinctly wider than anterior margin. The area of hypomeron that precedes the medial tooth is rugose, while the posterior area is smooth. The elytra, a little shiny, are fringed on the edges; the sutural angle is unarmed; they are covered with coarse punctures, and are a little rough behind; they show three obsolete longitudinal carinae, between which they are sulcate. The abdomen is slightly shining and almost glabrous; the ventrite V is slightly notched, and rounded at apex. The legs are pubescent with the tibiae rugose; the tarsi have the tarsomere I longer than the II and III combined, the II being the length of the III, V about as long as I; the lobes of the tarsomere III are narrow.” This description agrees very well with the holotype, except for the length of the antennae. Actually, they reach the posterior third of the elytra. But we have no doubt that this was a mistake in the description, because Lameere (1919) provided a drawing of Quercivir dohrni , also showing the antennae distinctly surpassing midlength of the elytra. This drawing of Q. dohrni by Lameere (1919) also shows the elytral carinae very well-marked, which is not true in the holotype, and also does not agree with the original description.

Galileo (1987a) did not examine the holotype of Q. dohrni , and believed it was deposited in the ISNB. Even so, she correctly recognized the species. Monné (2018c) and Tavakilian & Chevillotte (2018) recorded the holotype being deposited in the CMSP collection.
