Lispe nasoni Stein, 1898

( Figures 16a – f , 21g )

Diagnosis

Dorsocentral setae 2+4, the two presutural stronger and first two postsutural less developed, half the length of the third and fourth dorsocentral postsutural setae. Hind tibia on ad with a row of better developed setae (6 – 7) as compared to those that cover the tibia. Male hind femur with one row of short, robust setae on basal half of pv. Meron with a few setulae.

Redescription

Male. Colouration: Ground-colour black, with brown and silvery pollinose areas. Head ( Figure 16a ): Frontal vitta blackish with a silvery triangular band that is slender at the insertion of the antenna. Ocellar triangle blackish. Fronto-orbital plate, face, parafacial, gena silvery pollinose. Antenna dark brown, with light, silvery pollinose areas. Apex of pedicel yellow. Postpedicel and arista dark brown. Thorax ( Figure 16e ): Ground-colour black, with light brown pollinose areas. Scutum with five narrow, dark brown vittae, the two middle vittae along dorsocentral setae. Postpronotal lobe and notopleural with silvery pollinose. Pleura black with silvery pollinose. Wing: Hyaline. Calypteres whitish with slightly yellow margins. Halter yellowish. Legs: Femora dark brown, yellowish distally. Tibiae yellow and tarsi black, the fore tarsus yellowish pollinose, middle and hind tibiae with yellowish pollinose. Abdomen: Ground-colour black with silvery pollinose areas and well-defined dark spots on the dorsal region of tergites II, III, IV and V.

Head. Distance between eyes, at the level of the insertions of the antennae, 1/3 times head width. Three pairs of frontal setae. Postpedicel measuring 2 times the length of the pedicel.

Thorax. Intra-alar setae 1+2. Supra-alar setae 1+2, the second postsutural less developed. Postalar setae 2. Intrapostalar seta developed. Basal postpronotal setae 2. Notopleural setae 2. Scutellum with lateral and apical pair of well-developed setae. Anepisternum with six well-developed setae. Katepisternal setae 1+1+1.

Legs. Fore femur pd and pv with a complete row of setae; fore tibia on ad and p with one median seta; d, pd and pv with one apical seta. Mid femur ad with a median seta; av and v with a row of setae on basal half; p with two pre-apical setae; mid tibia a and p with median seta; a, ad, pv and av with one pre-apical seta. Hind femur ad with a complete row of setae; av with one seta on basal half; ad and av with median seta; av, ad and d with one pre-apical seta.

Terminalia . Not examined.

Female. Similar to male, but differs in space between eyes being bigger than in the male and hind femur without one row of short, robust, setae on basal half of pv.

Terminalia . Not examined.

Type material. Syntype. Male: ‘ Algonquin, III .\ 8.15.95 – 114 [white printed/hand-written label] ’; ‘ 4792 [white hand-written label] ’; ‘ USA [green hand-written label] ’; ‘ CoTypes [red printed label, only “ Co ” hand-written] ’; ‘ Lispa ♂ \nasoni\ Cotype Stein \ Prof P Stein det . 97 [white hand-written label] ’. Syntypes. USA, 1 ♂ and 2 ♀ same data as syntype ( ZMHU) .

Distribution. Bahamas Islands, Cuba, Mexico, Nearctic region, Puerto Rico, Virgin Islands of the United States ( Figure 21g ).

Comments. Lispe nasoni was originally described based on males and females from the USA (various states). Later, the cercal plate, sternite 5, and terminalia of the male and female were illustrated for the first time ( Snyder 1954).
