Key to species of Moiradiomus View in CoL
The species of Moiradiomus can be readily separated by characteristics of the male genitalia and the species of larval host plant. Additional morphological and color differences are added to the key as confidence characters, but we project that these will prove insufficient for identification purposes, particularly considering our small sample sizes and the potentially large number of undescribed species in the genus.
1. Male genitalia with short, broad paramere (length only 2× width) ( Fig. 32a View FIGURES 29–32 ); basal lobe in ventral view ( Fig. 32b View FIGURES 29–32 ) strongly tapered toward apex with rounded apical knob. Penis tube ( Fig. 32c View FIGURES 29–32 ) with slight angulation and irregular swelling near distal ½. Larvae develop on food bodies of P. reticulatum . Adults proportionally shorter ( Figs. 19, 20 View FIGURES 17–20 ) than other known species, with prosternal carinae ( Fig. 28 View FIGURES 25–28 ) nearly parallel, framing subtrapezoidal depression......................... M. nanita , n. sp.
1’. Male genitalia with paramere longer (length approximately 2.5–3.0× width) ( Figs. 29a, 30a, 31a View FIGURES 29–32 ); basal lobe not as above. Penis tube without angulation and swelling near distal ½ ( Figs. 29c, 30c, 31c View FIGURES 29–32 ). Larvae develop on other Piper hosts. Adult form elongate oval ( Figs. 13–18 View FIGURES 13–16 View FIGURES 17–20 ), prosternal carinae more or less distinctly converging toward apex, framing subtriangular to ovoid depression ( Figs. 25–27 View FIGURES 25–28 )........................................................................... 2
2. Male genitalia with basal lobe strongly unevenly tapered in apical half ( Fig. 29b View FIGURES 29–32 ), terminating in hook-shaped process resembling a vulture’s head ( Fig. 29d View FIGURES 29–32 ). Larvae develop on food bodies of Piper holdridgeianum . Adult with terminal maxillary palpomere elongate, moderately expanded distally ( Figs. 13, 14 View FIGURES 13–16 )....................................... M. clotho , n. sp.
2.’ Male genitalia with basal lobe nearly parallel-sided in apical half, terminating in oblique apex ( Figs. 30b, 31b View FIGURES 29–32 ). Larvae develop on other Piper hosts. Adult with terminal maxillary palpomere short, strongly expanded distally ( Figs. 15–18 View FIGURES 13–16 View FIGURES 17–20 )............ 3
3. Basal lobe of male genitalia with pronounced dorsal hump at basal 1/3, forming a conspicuous subangulation in lateral view ( Fig. 31a View FIGURES 29–32 ). Prosternum with strongly convergent carinae framing subtriangular depression with attenuate, narrowly rounded apex ( Fig. 27 View FIGURES 25–28 ). Larvae develop on food bodies of Piper friedrichsthalii . Adult form narrow, tapered toward apex; male with scutellar shield same color as elytron, and base of pronotum in front of shield with light brown transverse mark ( Fig. 17 View FIGURES 17–20 )........................................................................................... M. atropos , n. sp.
3’. Basal lobe of male genitalia with dorsal surface nearly flat, weakly sinuous in lateral view ( Fig. 30a View FIGURES 29–32 ). Prosternum with weakly convergent carinae framing elongate ovoid depression ( Fig. 26 View FIGURES 25–28 ). Larvae develop on food bodies of Piper lanosibracteum . Adult form less narrow, oval with lateral margins nearly parallel-sided, then rounded off in apical 2/5; male scutellar shield may be paler than elytron and base of pronotum in front of shield without brown transverse mark ( Fig. 15 View FIGURES 13–16 )...................................................................................................... M. lachesis ., n. sp.
