Hayden, James E. & Landry, Jean-François, 2020, Arcola malloi (Pastrana), the alligatorweed stemborer, a new synonym of Macrorrhinia endonephele (Hampson) (Lepidoptera: Pyralidae: Phycitinae), Insecta Mundi 2020 (768), pp. 1-25 : 7-8

Macrorrhinia parvulella ( Barnes and McDunnough, 1913)

Fig. 11 , 17 , 25 , 34 , 43 , 58 , 71

Divitiaca parvulella Barnes and McDunnough 1913: 183 .

Divitiaca parvulella consociata Heinrich 1956: 190 (“race”). Diagnosis. The forewing length is 4.5–6.0 mm. The maculation ( Fig. 11 ) resembles that of M. ochrella but is darker, rather cream-orange with dark scales and complete transverse lines, and the hind wings are darker gray than those of the other species. The gnathos ( Fig. 34 ) is not tapered, having a broadly rounded apex and recurved point. The ductus bursae ( Fig. 58 ) is not dilated near the corpus bursae; this section instead is represented by an appendicular lobe attached to the corpus bursae adjacent to the ductus bursae. Spines and signa are absent. The antrum ( Fig. 71 ) is proportionally small and narrower than the zone of microtrichiae with a convex posterior margin and short lateral projections.

Material examined. USA, FLORIDA, Miami-Dade Co.: 2 (2014, 2015), MGCL slide 1984, 1 male (1940), slide USNM 144164 ; Monroe Co.: 75 (1955, 1964, 1990, 1992, 1994–1996, 2015), MGCL slide 5202 ( FSCA), Key Largo : 1 male, 1 female (1967), CNC slides PYR 2199, PYR 2200 ( CNC) ; 50 males and females, Broward Co., Collier Co., Indian River Co. , Monroe Co. ( CNC, USNM) .

Comments. We examined the holotype but not the dissection slide of M. parvulella consociata (Heinrich) , described from Colombia. Shaffer (1995) listed it at the subspecies rank, and we have no reason to change its status.

The following two species are included for comparative purposes.
