Platypalpus canzonerii Raffone

Platypalpus canzonerii Raffone, 2002a: 79 .

Type material examined. HOLOTYPE Ƌ, labelled: “ Morbegno (Sondrio), River Fiume Adda, 5.VIII.1993, legit Canzoneri ” [genitalia dissected] ( MNHM) . PARATYPES: same data as holotype (1 Ƌ, 1 ♀) ( MNHM) .

Notes on type material. The male holotype is badly damaged (without head, right fore leg and left mid leg) with genitalia in a plastic microvial and it is a specimen of P. maculimanus (Zetterstedt) despite absence of fore leg tarsus annulations (illustrated by Grootaert & Chvála 1992, fig. 212), which was probably caused by immaturity or preceding maceration in alcohol. Genitalia of this specimen exactly, even in all small details (shape of cerci), agrees with P. maculimanus in Grootaert & Chvála (1992, figs 214–217) . Comparing the terminalia of the holotype with Raffone (2002a, figs 1–3) reveals inadequacies in Raffone’s (l.c.) figures: long and strong setae on tip of right epandrial lamella are omitted in his fig. 1, shape of right cercus is different (depicted as narrowed apically) from the original specimen (where it is broadened apically) and also shape of left epandrial lamella was peculiarly illustrated by Raffone (l.c.). The male paratype is well preserved and is clearly a male of P. maculimanus . The female paratype is also damaged (lacking left fore leg and three apical tarsomeres of right fore leg, lacking left hind leg and apical four tarsomeres of left mid leg) and represents a female of P. articulatus Macquart (see also discussion under P. subarticulatus Raffone, 2002 ). Although Grootaert & Chvála (1992) stated: “It is very difficult to distinguish the females of P. articulatus and P. maculimanus . Positive identification is only reliable with males”, we believe that their mutual recognition is possible according to microtrichosity pattern of the abdomen. Females of P. articulatus have abdominal tergites 3–5 entirely microtrichose laterally, whereas females of P. maculimanus have abdominal tergites 3–5 lustrous laterally, bearing at most narrow anterior stripe of microtrichosity. Moreover, the former species has slightly narrower lustrous spot on the katepisternum.

Remarks. Characters of P. maculimanus not previously mentioned in descriptions and specified here include: postpedicel up to 3X longer than broad; fore leg in some specimens darkened, especially fore femur posteriorly and sometimes also fore tibia brownish.

Platypalpus canzonerii is considered a new junior synonym of P. maculimanus .
