A new species of Medinodexia Townsend (Diptera: Tachinidae) from Japan, with a discussion on phylogenetic implications of the female postabdomen in Blondeliini Author Tachi, Takuji Author Huang, Yu-Zen text Zootaxa 2019 2019-07-18 4638 4 584 594 journal article 26172 10.11646/zootaxa.4638.4.8 2e85af1d-8c73-498a-a572-ee29db2ffdf5 1175-5326 3340549 339A0232-8CD7-4E32-B5A9-24784766A22C Medinodexia fulviventris Townsend, 1927 ( Figs 13 16 ) Medinodexia fulviventris Townsend, 1927: 57 . Lectotype ³ [by designation of Crosskey (1969: 98) ; Naturalis Biodiversity Center, Leiden, The Netherlands ]. Type locality: Indonesia : Sumatra , Tandjunggadang. Specimens examined. Malaysia , Borneo: 3 ³³, Sabah , Crocker Range , Inobong , 4–5.ii.2004 , T. Tachi & H. Shima leg. ( BLKU , ITBC ) ; 4 ³³, Sabah , Crocker Range , Inobong , 2.v.2004 , T. Tachi leg. ( BLKU , ITBC ) ; 3 ³³, Sabah , Crocker Range , Inobong , 2–5.ii.2006 , T. Tachi & H. Shima leg. ( BLKU ) ; 4 ³³, Sabah , Crocker Range , Inobong , 23–26.ii.2006 , T. Tachi leg. ( BLKU , ITBC ) ; 1 ♀ , Danum Valley , West trail, 25.xi.2002 , Malaise trap , T. Tachi leg. ( ITBC ) . Diagnosis. Very similar to M. japonica sp. nov. , but differing from it as follows: antenna with first flagellomere rather long, approximately 4.5 times as long as pedicel; gena approximately 0.2 of eye height; fore tibia with 2 posterior setae; male abdominal sternite 5 elongated, rectangular, distinctly longer than wide; male cercus slightly slenderer than that of M . japonica in lateral view. Distribution. Indonesia ( Sumatra ), Malaysia (Borneo). Host(s). Unknown. Remarks. Tachi & Shima (2010) included this species, as “ Medinodexia sp.”, in their molecular phylogeny, and it was classified in Blondeliini . It is very similar to M . japonica sp. nov. in the male and female postabdominal characters, but the male sternite 5 differs distinctly from that of M . japonica in the long anterior part. This is the first record of this species from Borneo, Malaysia . No hosts have so far been recorded for this species. A detailed description was given by Shima (1997) .
