"Lepisiota frauenfeldi" analysis

Bolton's "New General Catalogue" (1995: 226-229) has many names which were published originally as subspecies, varieties or races of "Acantholepis frauenfeldi". It seems that the almost random efforts of various other modern authors has led to some names being elevated to species rank, e.g. dolabellae, melanogaster, melas, nigra, nigrescens, semenovi, sericea, splendens and syriaca. There still remains two confused "species" with many supposed synonyms and subspecies (Bolton's preferred term inclusive of varieties, stirps, etc.).

This list quite clearly is wholly misleading and the "species" is in a highly confused and poorly differentiated state. Simply on the basis of historic descriptions and illustrations, I have attempted to bring some clarity and, hence, this analysis page. The links are to the key sections below.


{Lepisiota frauenfeldi}Mayr's (1855) description is on {original description}.


Translation of Mayr (1855) description of the type form [translation from German, Marcus Stüben, 15.11.2006]
Hypoclinea frauenfeldi Mayr 1855 Lepisiota frauenfeldi (Mayr 1855)
[latin description] (...) TL 2,5 - 3mm [further parts of the Latin description match the German description]
"WORKER: brownish black or pitch-black, the ventral side of the head, the antennae except the funiculus end of the scape (= distal part of the scape), the alitrunk, the joints of the legs and the tarsi brownish yellow-red, sometimes the alitrunk has dark spots on the pronotum and on part of the mesonotum, also quite often on the propodeum [metanotum]. The shiny body is nearly hairless, just the mandibles, the antennae and the legs are more pilose. The head is broader than the alitrunk and nearly egg-shaped. The mandibles are very shallowly and extensively wrinkled (= rugose) and their inner (= masticatory) margin dentate. The clypeus is carinate, seemingly smooth but with higher magnification it is very shallowly and extensively wrinkled (= rugose)), behind the frontal margin and along this margin there is a shallow groove. The frontal carinae are very narrow. The scape of the 11-segmented antennae is very long, reaching - if put back - back until the frontal margin of the mesonotum and is thickened at the funiculus end (= distal part); the funiculus is longer than the scape, filiform and apically a little thicker than the basal part. The frontal triangle [= Stirnfeld], forehead and occiput are seemingly smooth, but with higher magnification they appear very shallowly and extensively wrinkled (= rugose). The median frontal groove is indistinct. The occiput is not sinuate. The alitrunk is finely rugose, the mesonotum is compressed laterally, the basal part of the propodeum is higher than the mesonotum and formed in such a way that the two teeth are at the tip of the propodeum, which is hollowed between the two teeth. The petiole is high and thick, above strongly cut out semicircularly, so as to form two very acute and long teeth and produced on either sides [really two teeth on either sides of the petiole??]. The egg-shaped gaster is finely rugose, broader and nearly as long as the alitrunk. The legs are long. This very delicate and slim species was previously found only at Sign in Dalmatia by Mr. Frauenfeld."


Agosti & Collingwood (1987b) separated frauenfeldi and Lepisiota nigra, both being at least mainly dark, with alitrunk no more than slightly sculptured and the petiole toothed, by the first having part of the alitrunk usually with a small patch of red and the pronotum sculptured; while the latter is wholly black and has a smooth pronotum. Recorded once from Saudi Arabi by Collingwood (1985: 295) and not listed from the Arabian Peninsula by Collingwood & Agosti (1996).

Historic Keys -
Forel's (1892a) key with separation of four varieties (bipartita, syriaca, sericea and pubescens), is at {original description}.
Forel's (1894c) key with a short description of integra is at {original description}.
Santschi (1917d) gave a review of the then known species that; with an illustration of petiole shapes, and adding eleven new varieties or strains, is at {original description}.
Kuznetsov-Ugamsky (1929c) reviewed numerous specimens he had collected in Turkestan (primarily across the south of modern Turkmenistan and Uzbekistan) and provided a key to the many forms he chose to describe as new subspecies or varieties of frauenfeldi; this is at {original description}.

Modern Revisions
Agosti & Collingwood (1987b) separated frauenfeldi and nigra, both being at least mainly dark, with alitrunk no more than slightly sculptured and the petiole toothed, by the former having part of the alitrunk usually with a small patch of red and the pronotum sculptured; while the latter is wholly black and has a smooth pronotum.

As with "frauenfeldi" semenovi is an obvious mess and I have tried to produce some clarity in the table that follows. A puzzle is why Kuznetsov-Ugamsky (1929c) lumped together forms with obviously very different petiole shapes under one heading as varieties of frauenfeldi. Then after Pisarski (1967) separated off some as species, Dlussky and his colleagues separated semenovi but lumped Pisarski's species back under semenovi.
