Genus Prionopetalum Attems, 1909 View in CoL
Prionopetalum Attems, 1909: 51 View in CoL .
Type species: Prionopetalum serratum Attems, 1909 View in CoL , by original designation.
Unlike many other genera of Odontopygidae , Prionopetalum is well-defined and quite homogeneous, not only in non-sexual characters, but also in gonopod structure.
Diagnosis
(Modified after Kraus 1960 and VandenSpiegel & Pierrard 2009, excluding some non-gonopodal characters which were mentioned by these authors but which are of no diagnostic value.)
Prionopetalini in which the anal valves have a raised rim, a well-developed dorsal spine and sometimes a smaller ventral one; limbus with simple, pointed denticles (true of all species after removal of “ P.” fasciatum , see below).Male legs with ventral soft pads on postfemur and tibia, except on anteriormost and posteriormost legs (true of all species after removal of “ P.” fasciatum , see below).
GONOPODS. Coxal metaplica on its basal part with a large longitudinal mesad flange (mlf), separated by a deep sinus from an oblique-horizontal sub-semicircular mesad flange (mof). Telopodite with a posttorsal (“femoral”) spine (pts), but without a (“tibial”) spine near the origin of the solenomere, divided into solenomere and telomere shortly after post-torsal narrowing. Solenomere (slm) simple, whip-like, without outgrowths (exception: P. fryeri ( Turk, 1956) with a short accessory branch at c. ⅔ of the solenomere’s length). Telomere with two characteristic processes: a variously shaped, often speciesspecific proximal process (tpp) which projects at ± right angles from the main telomere axis, and a long, slender distal process (tdp) which is armed with a row of spines or thorns. ( In the terminology of Kraus (1960), tpp is “eine hornartige Spitze oder auch eine entsprechende, schalige Lamelle ”, and tdp is “der meist auffallende schlankere Distalabschnitt ….. gezackt oder bezahnt”. For VandenSpiegel & Pierrard (2009), tpp is a “processus basal du tarse”.)
Body size
Published body diameters for adult males range from 2.5 mm ( P. exaratum , P. glomeratum ) to 6.8 mm ( P. bifidum ), but a male of P. frundsbergi in the ZMUC collection has a diameter of 7.6 mm. Published numbers of podous rings range from 57 ( P. exaratum ) to 71 ( P. bifidum ), but the above-mentioned male of P. frundsbergi has 72 podous rings. Table 1 View Table 1 and Fig. 2 View Fig. 2 summarise the size information and give detailed information for the two Udzungwa species. One has been subtracted from published “segment” numbers because these have traditionally included the telson. Two records have been omitted: “nearly fourty-three” for P. clarum ( Chamberlin, 1927) and 93 for P. tanganjikum Verhoeff, 1941 – the latter number is probably a lapsus calami.
