Subgenus Ashima Chen, 2011 View in CoL

Ashima Chen View in CoL in Cao et al., 2011: 682 (as subgenus of Phortica View in CoL ); Gong et al., 2018: 438. Type species: Phortica xyleboriphaga Senior-White, 1921 View in CoL .

Diagnosis. Projections at anterolateral corners of the cibarium longer than 1/2 width of cibarial, anterior margin (ch.10-1; Fig. 2C View FIGURE 2 ); mid-dorsally constricted epandrium (ch.29-1; Figs 3B,D View FIGURE 3 , 4B View FIGURE 4 , 6D View FIGURE 6 , 7E View FIGURE 7 , 8G View FIGURE 8 , 9F View FIGURE 9 ); less sclerotized, broad lobe-like surstylus (ch.34-1; Figs 3E View FIGURE 3 , 4B View FIGURE 4 , 5C View FIGURE 5 , 6D View FIGURE 6 , 7E View FIGURE 7 , 9F View FIGURE 9 ); hypandrium with a pair of anterolateral, inward extensions articulated to base of pregonite (ch.42-1; Figs 3C,F View FIGURE 3 , 4D View FIGURE 4 , 5E View FIGURE 5 , 6G View FIGURE 6 , 7F View FIGURE 7 , 8J View FIGURE 8 , 9I View FIGURE 9 ).

Shared characters. Characters described as commonly seen across this subgenus (the Phortica foliiseta species complex at that time) by Chen et al. (2005b) are not repeated here. Occipital setae on lower portion shorter than postocular setae (ch.2-0; Figs 7A View FIGURE 7 , 9A View FIGURE 9 ). Pedicel with only 1 thick seta (ch.4-0; Figs 2A View FIGURE 2 , 4A View FIGURE 4 , 5A View FIGURE 5 , 6A View FIGURE 6 , 7C View FIGURE 7 , 8A View FIGURE 8 , 9B View FIGURE 9 ). Clypeus medially pale (ch.8-1; Fig. 8F View FIGURE 8 ). Lateral membrane of proboscis scale-like patterned (ch.13-1; Fig. 2D View FIGURE 2 ). Prominent postpronotal seta 1. Epandrium not extended at anteroventral corner (ch.30-1; Figs 3D View FIGURE 3 , 4B View FIGURE 4 , 6D View FIGURE 6 , 7E View FIGURE 7 , 8G View FIGURE 8 , 9F View FIGURE 9 ). Surstylus completely or largely covered with epandrium (ch.36-1; Figs 4B View FIGURE 4 , 7E View FIGURE 7 , 8G View FIGURE 8 , 9F View FIGURE 9 ), with pubescence (ch.38-0; Figs 3E View FIGURE 3 , 4B View FIGURE 4 , 5C View FIGURE 5 , 6D View FIGURE 6 , 7E View FIGURE 7 ). Cercus longer than twice of width (ch.39-0; Figs 3B,D View FIGURE 3 , 4B View FIGURE 4 , 5C View FIGURE 5 , 6D View FIGURE 6 , 7E View FIGURE 7 , 8G View FIGURE 8 , 9F View FIGURE 9 ). Pregonite articulated to tip of aedeagal guide (ch.54-1; Figs 3G View FIGURE 3 , 4I View FIGURE 4 , 5G View FIGURE 5 , 6E View FIGURE 6 , 7G View FIGURE 7 , 8D View FIGURE 8 , 9C View FIGURE 9 ), without sensilla on apical portion (ch.51-0; Figs 3G,H View FIGURE 3 , 4C View FIGURE 4 , 5D View FIGURE 5 , 6E View FIGURE 6 , 7G View FIGURE 7 , 8I View FIGURE 8 , 9G View FIGURE 9 ). Phallapodeme vertically flat plate, with posterior, rod-like process apically articulated to aedeagal median rod (ch.60,61-1; Figs 3G,H View FIGURE 3 , 4C View FIGURE 4 , 5D View FIGURE 5 , 6E View FIGURE 6 , 7G View FIGURE 7 , 8I View FIGURE 8 ). Aedeagal sheath with more or less sclerotized postgonite(s) (ch.64-1; Figs 3 View FIGURE 3 F–H, 4D, 5D,E, 6F,H, 7F, 8I–K, 9G–I).

Key. The digital, multiple-entry key “ Ashima View in CoL ( Diptera : Drosophilidae View in CoL : Phortica View in CoL )” to all species of this subgenus has been constructed largely based on the character matrix of Appendix 1, and its database package including software instructions is available from the following website: https://drive.google.com/open?id=10ht68FhP1DJDg h2T33kZn7I2ro8YGGX0.
