Vitzthumegistus andrei

(a nomen novum for Cyclothorax carcinicola von Frauenfeld, 1868 , sensu Vitzthum, 1928)

(q.v. von Frauenfeld, 1868: 893; Vitzthum, 1928: 194; q.v. Oudemans, 1932: LXI; q.v. Vitzthum, 1937: 638; q.v. Johnston, 1960: 442; q.v. Kethley, 1977: 139)

Diagnosis — Cercomegistoid vitzthumegistid mite. Anterior end of dorsal shield with a pair of distinctly long i1 (= j1) setae (see Vitzthum, 1928: 195, Fig. 3). Dorso-lateral (marginal) setae long, close to length of genua. Ventrianal shield wide, almost covers venter. Fused metapodal-endopodalexopodal-peritrematal shields element fused with ventrianal shield posteriorly.

Type series — Syntype: Two males (slide number: V1207, V1208; each mounted on a thin square cover slip). ex. Coenobita sp. (Paguroidea: Coenobitidae ); Coll. Fulmek (Leopold Fulmek, 9 November, 1883 – 17 June, 1969), August, 1925. Type specimens located in Hermann Graf Vitzthum collection, Zoologische Staatssammlung (ZSM), München, Germany.

Type locality — INDONESIA: Northeast coast of Sumatra Island, Beach of Perbaungan .

Remarks — The Vitzthum Collection in Zoologische Staatssammlung (ZSM) has two additional microscope slides (slide number: V1214, V1215), which carry the mite specimens from Coenobita sp. collected by Johannes Carolus van der Meer Mohr (1892-1969) in March, 1933 at the same type locality (Beach of Perbaungan) in Sumatra Island. Slide V1214, in poor condition, contains three female specimens mounted together on a thin square cover slip, and slide V1215 carries a single male mounted on a thin square cover slip. Slide V1215 lacks gnathosoma, anterior dorsum, and legs I; and through the V1214, I was able to confirm the presence of three-tined palptarsal claws and polyramous hs1 setae. However, these four specimens in V1214 and V1215 slides were not included in the original description of Vitzthum (1928), and cannot be treated as name-bearing types. For the minimal change of name, I followed the same specific epithet, andrei , that Kethley (1977: 139) proposed in honor of Marc AndrØ (10 February, 1900 – 28 May, 1966). Immatures and biology are unknown.
