„Heteromysis sixi“, die neue Garnelen Spezies!

Am 9.1.21 erhielt ich von unserem Zoo Vizedirektor Dr. Daniel Abed Navandi die folgende E-Mail: 

Lieber Herr Six, 

anbei das vorab veröffentlichte Autorenexemplar: 

(Four_new_Heteromysis spp_accepted_author_version_2020.pdf) Sie sind darin als "citizen scientist" und "promoter" des ‘Haus des Meeres’ angeführt (auf den Seiten 49 und 50). 

Heteromysis sixi:

Etymology: "The  species  name... dedicated on the occasion of his retirement to Franz Six, citizen scientist and 55 year-long promoter of the ‘Haus des Meeres’, a public marine aquarium in Vienna.

Holotype: HAWAII • ♂ ad., BL 3.0 mm (on slides); Honolulu, Waikiki Beach, Waikiki Aquarium; Jan.

2020; Gwen Lentes leg.; NHMW 26964. 

Es mir jedenfalls ein Anliegen, Ihnen und der Familie Six so für die Schaffung des Wiener Meeres zu danken! 

Mit lieben Grüßen,

Heteromysis (Olivemysis) sixi sp. nov

urn:lsid:zoobank.org:act:A5C4DF45-0137-4A0F-AAB5-4C71E081755C

Etymology

The species name is a noun with male ending in genitive singular, dedicated on the

occasion of his retirement to Franz Six, citizen scientist and 55 year-long promoter of the

‘Haus des Meeres’, a public marine aquarium in Vienna.

Holotype

HAWAII • ♂ ad., BL 3.0 mm (on slides); Honolulu, Waikiki Beach, Waikiki Aquarium;

Jan. 2020; Gwen Lentes leg.; NHMW 26964.

Diagnosis

Only male holotype known (ranges of meristic characters are here indicating differences

between left and right side of the body). Rostrum (Fig. 12A) triangular with narrowly

rounded tip, 2/3 length of terminal segment of antennular trunk. Cornea (Fig. 12A, B)

occupies distal third of eye surface. Eyestalks with smooth surface except for a prominent

tooth on disto-mesial edge. Antennular trunk (Fig. 12C–E) with blade-like, subapically

flagellate spine in addition to setae on disto-mesial edge. Distal 16–24% of this spine with

rugged, obliquely truncate margin. Antennal scale (Fig. 12A) undivided, extending

shortly beyond antennal peduncle; scale length 2.4–3.0 times maximum width. Thoracic

sternites (Fig. 12H) with short median processes. Flagellum of thoracic exopod 1 with 8

segments, exopods 2–8 with nine segments (Fig. 13A). Carpopropodus of thoracic

endopods 1–8 with 2, 2, 2, 4, 6, 6, 6, and 6 segments, respectively. Thoracic endopod 3

(Fig. 12I–M) without tooth-like extension on disto-mesial edge of merus; carpopropodus

length 5/2 maximum width. Distal 44–64% of male carpus 3 with total of six flagellate

spines along inner margin; propodus without paradactylary setae. Penes (Fig. 13A)

cylindrical, apically blunt, ending in five blunt lobes; size 3/4 length of ischium 8; small

setae present at half penis length. Pleopods (Fig. 13B–G) rudimentary, unsegmented, with

residual differentiation of endopod (pseudobranchial lobe). Male pleopods 1, 3–5 normal,

without spines. Pleopod 2 with large smooth spine (stylet) on apex and three minute

flagellate spines in series along distal half of outer margin of elongate distal portion.

Exopod of uropods (Fig. 13H) 1.2–1.3 times length of endopod; endopod with only one

small spine near statocyst; distal spine-free portion is 2/3 length of endopod. Each lateral

margin of telson (Fig. 13I) with six spines on distal half, proximal portion smooth. Ushaped

apical cleft penetrates 1/3 telson length; proximal 5/6 of cleft with 26 laminae.

Disto-lateral lobes each with two spines on narrowly truncate apex. The outer apical

spines are 16–18% telson length; inner apical spines are 0.2–0.3 times length of outer ones.

Abgesehen davon, dass ich mich über diesen Ausdruck der Wertschätzung sehr gefreut habe, war es mir ein Anliegen, unserem Dr. Abed Navandi und seinen Kollegen zur Entdeckung der neuen Garnelen Spezies herzlichst zu gratulieren.

Die Forschung ist neben der exzellenten Tierhaltung und Information der Gäste die wichtigste Aufgabe eines „Wissenschaftlich geführten Zoo(s)“
