A revision of the Afrotropical species of Pachylophus Loew (Diptera: Chloropidae) and some related Ovoviviparous genera Author Deeming, John C. text Zootaxa 2018 2018-09-17 4482 1 1 51 journal article 29184 10.11646/zootaxa.4482.1.1 72a80b13-e18f-4dc3-bec2-bb20d17f0e5f 1175-5326 1454415 79FECD6E-5192-45C3-9B46-4E6817366F64 Pachylophus femoratus ( Johnson, 1898 ) ( Plate 4 , Fig. 19; plate 5, Fig. 22; plate 12, Figs 58, 59) Elachiptera femorata Johnson, 1898 : 164 Pachylophus tellinii Bezzi, 1908 : 177 , syn. n . Pachylophus frontellinus Speiser, 1910 : 196 Pachylophus cymbiformis Becker, 1916 : 426 Described as a species of Elachiptera from Somalia , this species is further recorded from Rhodesia , South Africa , Tanzania and Uganda . P. frontellinus Speiser, 1910 : 196 and P. cymbiformis Becker, 1916 : 426 are junior synonyms. In NHMUK are 2♂ (one of them headless) labelled "Durban, F. Muir" determined by C.G. Lamb as P. frontellinus . Misidentifications are listed under P. frontalis (below). Dr. Ebejer informs me that he has run the type of P. cymbiformis through the above key and that it traces perfectly to femoratus . Through the kindness of Mrs. Sarah Whitman of the Museo Zoologico de "La Specola", Museo di Storia Naturale, Firenze I have been able to examine the unique holotype of Pachylophus tellinii Bezzi, 1908 from Eritrea . This is in good condition, though the tips of the wings are damaged. It bears the following labels: (1) male sex sign (2) red " Typus " label, (3) ERITREA : ADI-UCRI, vii.1901 , Dr. A . Andreini, (4) what appears to be "1109" on a diamond-shaped label, (5) " Pachylophus Tellinii n. sp." handwritten. It is without doubt conspecific with Pachylophus femoratus (Johnson) .

There is a striking difference in the ground colour of the thorax, abdomen and, to a lesser extent, the legs of the above material, that from Ethiopia and the Mt . Kenya specimen being considerably darker, appearing blackish brown, whereas those from elsewhere are ferruginous, the South African (Pirie Dam) material, which is mature, being especially pale. In addition to the above-listed material 2♂ 4♀ collected with the typical material by Dr. Ismay at 10km S. of Harare appear to be a different species, being slightly smaller, having the frons less projecting and consequently the frontal triangle shorter and with straighter sides, the hind margin of the surstylus less concave (forming a concavity of one quarter of a circle in typical form) and the angle between gena and occiput lightly dusted (shining in typical form). However, amongst Dr. von Tschirnhaus' material are specimens which are morphologically intermediate between the typical form and that from Harare , having the frontal triangle variable in shape and the dusting of the genal/occipital angle dusted. These specimens lead me to consider that all should, for the time being at any rate, be regarded as representing the same species. Within the Chloropinae characters of male terminalia are often misleading, and the unfortunate result of workers figuring the same structure from a slightly different angle can lead to confusion. This morphologically intermediate material is: 3♂ 2♀ , TANZANIA : foot of Mt.

A dissected female from Mulu was found to contain a well developed larva with shell membrane still attached. Puparium 3.75mm in length, 0.96mm in greatest breadth, tubular, smooth surfaced and yellowish brown in colour; mandibular sclerite ( Plate 5 , Fig. 22); anterior spiracles similar to those described here for P. pellucidus , transversely orientated and situated on lateral edges of dorsal emergence cap; posterior spiracles small, uncoloured and not raised above puparial integument, those figured here ( Plate 4 , Fig. 19) showing the right hand spiracle to have 3 large respiratory pores, whereas the left hand one has the appearance of the development of a further pore.
